Especially in the dead of winter?? It’s pretty much the only thing I can think about at this very moment. I mean, do you see the all that cheese??
I am dying. All the cheese please!
So we have serious things to chat about today, and when I say serious, I’m talking about this very simple vegetarian skillet lasagna. I’m sure after looking at this gooey deliciousness that you might like to start making this pretty much ASAP, right?!?! I get that, actually, if you are reading this bright and early… I would tell you to add a fried egg and call it breakfast.
That may be kind of weird, but man it would be delicious!

Getting back on topic here, I think I’ve said this before, but my family really loves lasagna. It’s just one of those cozy family dinners that everyone loves. When I make it for the whole fam, I always go the classic route, but last week I just really wanted lasagna, and I really really wanted to do ZERO work to get it.
Like no pasta boiling, pasta layering, sauce making or baking for an hour plus. No, NONE of that please.
Obviously, the whole ZERO work lasagna thing was never going to happen, but this lasagna recipe is the next best thing. Read: ONE skillet, NO layering lasagna noodles, NO boiling lasagna noodles, made in under one hour and actually a pretty healthy veggie filled meal… if you count cheese as healthy, which you should all know by now that I DO. Duh.

Sounds pretty awesome, right???
It totally is, and it’s totally delicious and satisfying… even without any meat! To bulk up the sauce, I used a mix of zucchini, mushrooms and lentils. I am on a big veggies and lentils kick right now. I’ve basically been swapping them for meat in almost any and every thing I make. I know that may sound scary to you meat lovers out there, but can I just say that this skillet lasagna got two thumbs up from my plain eating, meat loving, mother. Her reaction to this meal made me SO happy!
I got my mom to eat lentils!! LENTILS!! YESS. She hates beans and legumes of any kind, so when I can sneak them into her food… AND she actually likes the food, it is a very good day!
P.S. who could not like beans?? Hello bean burritos, beans and rice…cheesy beans?? YUM.

The point is that this lasagna passed the picky eater test. Meaning I feel like you can totally get your kids to eat this. And if you don’t have kids? More for you (leftovers are KILLER)!!
I also feel like this would be another great Valentine’s Day dinner. Shhh, no one needs to know that you didn’t slave over the stove all day long. That can be our little secret. 🙂

As for my cheese choices? Mozzarella, provolone and parmesan, the classic Italian line up.
Nothing better.
And hey, all the veggies and lentils cancel out any issues you may have with the cheese, right?? OF COURSE, no other way to look at. So you see??!!! Here you have a have super yummy, cozy and romantic Valentine’s Day meal that’s pretty simple… and healthy too!
Now all you need is the wine, the chocolate and all the flowers your money can buy…seriously.

Is there anything better than a plate full of lasagna?? The answer is noooooo and this Simple Vegetarian Skillet Lasagna is something you have to try! Vegetarian or not!
Ingredients
- 2 tablespoons olive oil
- 1 zucchini chopped
- 8 ounces button mushrooms finely chopped
- 1 red pepper seeded + chopped
- 2 cloves garlic minced or grated
- 1 jar roasted garlic or tomato basil pasta sauce
- 1 cup milk
- pinch of crushed red pepper flakes
- 1/2 cup oil packed sun-dried tomatoes oil drained
- 1/2 cup rinsed green lentils
- 6 ounces no boil lasagna noodles
- 2 cups fresh spinach
- 1 cup fresh basil
- 8 ounces mozzarella sliced
- 4 ounces provolone shredded
- 1/3 cup grated parmesan plus more for topping
- pesto, for serving (optional)
Instructions
-
Preheat the oven to 375 degrees F.
-
Heat a large, high-side skillet or dutch oven over medium heat. Add a drizzle of olive oil. Once hot, add the zucchini, mushroom and red pepper. Season with salt + pepper. Cook 3 minutes or until just lightly caramelized. Add the garlic and cook another minute. Stir in the tomato pasta sauce, milk and a pinch of crushed red pepper flakes. Stir in the sun-dried tomatoes, lentils + 1/4 cup water. Break each lasagna noodle into 2-3 pieces and stir them into the sauce, making sure most of them are submerged. Cook until the noodles are al dente and the lentils are soft, about 15 minutes. If the sauce seems like it is getting too thick, add water to thin.
-
Stir in the spinach + basil until they have wilted down into the sauce. Remove from the heat and add the mozzarella, provolone and parmesan.
-
Place the skillet on a large baking sheet. Place in the oven and bake for 10 minutes or until the cheese has melted and is bubbly. Remove and let sit 5 minutes. Serve with basil pesto and fresh parmesan. Enjoy!

Oh, and maybe some extra parmesan and chunky, garlicy, brown butter basil pesto. OH, oh… and some toasted bread too, obviously.
i love all your time-intensive, millions of ingredient recipes, but i’m also really digging these quicker ones, too! and adding coconut milk is giving me a baked ziti kind of vibe, yum!
Nom nom! This is perfect for me ♥ I would eat all by myself ♥
summerdaisy.net
Love how simple this is! Also that you sneaked in some lentils, would make me feel a bit better about myself! So tempted to make this for dinner tonight 🙂
Oh yum, this is the best ! Sounds awesome, perfect and all that stuff. I have to try this 🙂
aiaiaiaiaiiii I could gobble this one down right now!!! Looks so amazing and yummy!!
http://bloglairdutemps.blogspot.pt/
Simply perfect, delicious !!!!!!! 🙂
This looks fabulous! I love meatless meals too:) And as always, gorgeous photos!
This is the perfect quick weeknight dinner or a Friday night dinner during Lent!!
This first photo is stunning!
THANK YOU!
Yes, all the cheese!
What I want to know is whether you told you mother about the lentils before or after she ate it! I have a daughter who is just like your mom, so I’m always making bean-less chili. I’m going to have to make this lasagna when she returns from London and see what she thinks.
Thanks, Tieghan!
I totally agree, lasagna just calls to me in the winter! I love the lentils in this!
Vegan cheese sits better in my stomach, but I love the occasional mozzarella and goat cheese! This skillet looks to DIE for! I wouldn’t share it with anybody!
I seriously need to acquire a skillet so I can make all of these delicious skillet-y things. I have to start my no-dairy, no-legumes, no-grains, no-sugar, month-long diet this coming week, so this recipe will have to wait, but oh, it will be a good one to savour afterwards.
YOU NEED a skillet! 🙂
This looks perfect! You’ve got all the best things going on here with the no-precook noodles, lentils and veggies. Thanks so much! I can’t wait!
Thank you so much, Karen!
Lasagna in a cast iron skillet is so genius! I am loving this idea!

Thank you! 🙂
Tieghan! I love the mix of veggies, cheeses and those no-boil noodles! I actually prefer the texture of those noodles. This looks dreamy…pinning so I can make it this weekend!
THANK YOU! Have a great weekend!
Quick, easy, AND picky eater approved? What more could a gal ask for? Usually I am all about the classic lasagna, too, but these days something quick that will warm me up without a ton of effort is a necessity. Basically, gimme all the skillet lasagna!
hehe! Thank you so much, Amanda! 🙂
This recipe is everything! I cannot wait to make it for myself! Also, your photos are stunning!

THANK YOU!
Tieghan, these pictures are gorgeous! And I love the idea of a rustic, meatless lasagna. I agree, perfect valentine’s day meal!
Thank you!
Ohhhh I’m excited about this one! (as I am about all your recipes<3)
THANK YOU! It means a lot! 🙂
Veggies dunked in cheese – yes, gimme this lasagna!
Thanks Naomi! Have a fun weekend! 🙂
to answer your first question, no, there is nothing better than a plate full of lasagna. this looks incredible. i’ll have to try this.// ▲ conundrumofcoitus.com ▲
haha! Thank you so much! 🙂
I LOVE lasagne but I agree that sometimes it is just too much effort and takes so long! Your quick version sounds amazing and I may just try it out on Valentines.
Thanks Hannah!
It’s like you’ve read my mind – I’ve been looking for a vegetarian lasagne for a while now. The lentils is a great way to get a meat like texture and I imagine the mushrooms help too.
This looks delicious and I too am a cheese fiend, so more melted cheese please!
hip, hip for cheese!! 🙂
Thank you!
I made this last night and I can’t stop eating it today. So delicious! I can’t wait for your cookbook!
YEAHH!!!! This makes me so happy, thank you! Have a great weekend!
This look sooooo delicious! And all that melted cheese, yum! 🙂
Thank you! Have the BEST weekend!
Made this tonight and it was really good. I liked the coconut milk in it along with the fresh basil – almost a Thai Lasagna. Thank you Tieghan.
This looks so so good!
Kisses from http://poshnessary.com ❤
This looks so delicious and the perfect night-in meal.
This might just be my dream dinner. Adding it to my must-make list for the week! 🙂
Wow! Looks amazing, all that cheesy goodness.
I made this for meatless Monday and it was a huge hit! My husband and oldest child usually don’t love zucchini, but they raved about this lasagna. We are trying to get more vegetarian options in the rotation and this was awesome. Thank you!
I made this last night and the whole family loved it. My daughter helped me cook but was skeptical since she likes neither mushrooms nor zucchini but ended up liking it a lot. My only problem was the noodles falling too much apart – I would have liked bigger pieces. But definitely a recipe I will be making again – thank you!
brilliant – I hate cooking lasagna noodles!
Thank you!
This looks unbelievably good! I can’t wait to make this on Saturday for company! Although I don’t have a skillet so I’ll have to use a metal saute pan. I need to buy a skillet; What is the size/diameter of your skillet? Thanks!
I used a 12 inch skillet. Let me know if you have questions and I hope this is a hit! 🙂
Made this twice now, its really good! Made a couple of substititions, carrots for zucchini, and boiled whole wheat noodles. Only issue I had was both times the lentils were still somewhat hard. Not sure if this is how its supposed to be, but I’ll try soaking them prior next time. Thanks for the easy recipe:)
SO happy you love it! Thank you!! I like the lentils a little firmer, but some people prefer them softer. Have a great weekend! 🙂
Wow this looks divine! I went veggie for Lent so this perfect! Thank you!
Lots of Love, Lottie | Lifestyle blog to make you smile 🙂
This is a great recipe!! One thing – for the traditional baked lasagna it is NOT necessary to boil the noodles! The noodles will cook in the tomato sauce when you bake! Just pointing out because you talk about how much work it is, and I myself experienced all that boiling before I learned you can skip that step with no negative effects.
Made this tonight. Family really liked it! Again, another keeper. I did have trouble with the lentils and simmered it for 45 min. I will use brown lentils or presoak the green ones next time.
So happy you and your family loved this, thank you!
Unfortunately, despite the sauce boiling the entire time, the lentils took 45 minutes to cook. In that space of time the noodles became overcooked and stuck to the bottom. I would strongly recommend cooking the lentils separately and adding them so you don’t ruin the meal waiting for them to cook (and make everyone wait an extra half hour for lunch) – no one wants to find hard lentils and over cooked stuck-on noodles aren’t fun either. Sorry I can’t recommend this recipe as is.
I am really sorry you had trouble with this. I do like my lentils a little firm so that may have been the issue. Again, very sorry.
Woweeee! I knew when I saw this I’d love it and had to make it right away!! Made it Friday night and LOVED it!!! What a genius way to make a lasagna! And I loved the addition of lentils! gave it a nice nuttiness! mmm Thanks for a great recipe!
Hi there,
This looks delicious – I can’t wait to try it! May I ask what size Staub skillet you were using (the 10″ or the 12″)? I’m about to purchase one and can’t decide between the two.
Thanks!
For this I use the 12 inch, but I use the 10 inch almost everyday! Thanks!!
Do you think I can use a different type of pasta here?
Hi Lindsay! Yes, you can use any cut you’d like. Let me know if you have any other questions. Thanks!
I made this tonight and it was a big hit with the family. I used red lentils because they cook faster and my husband doesn’t like “firm” lentils. Really tasty!
Oh, and I also used regular fusili pasta
I made this tonight. My husband LOVE it! I’m wondering, since I’m journaling, what is the nutritional value of this meal per serving?
SO happy you love this, thanks! I am sorry, but I do not no the calories for this.
Hello! I’m part of a team making a literary magazine for a college project, and I was wondering if I could use that first photo in the magazine! You would receive credit for the photo as well as a pdf version of the lit mag, if you contribute. If you’d prefer not to, that’s totally okay!
Hey Alyssandra! That is fine with me, you can use my photo. Thanks!
Hi Tieghan, I made this as well as the sunflower veggie burgers. This was absolutely double delicious. And so much of it! It will save me from having to cook tonight and tomorrow night as well! I was going to say what kind of green lentils do you have over there?! But I see from other comments that I am not the only one with uncooked lentil problems! To even get them cooked it took a good 45 mins. I did wonder if when you said ‘rinsed’ you meant ‘cooked’! As a consequence I also added quite a lot of water to keep it going. It was all fine though and a lovely cheesy sloppy lasagne was the result! Thank you!
This was super easy and fast for an Italian Weeknight dinner! The whole family loved it. Great job Food Network!! THIS IS A Keeper!
Thank you Anastasia! So happy you loved it!
You should probably include that parmesan cheese is not vegetarian, unless you specifically buy veggie parmesan. Also, most pesto contains parmesan, thereby also making it not vegetarian. You need to specifically find vegetarian pesto also.
I made this last night, but used whole grain pasta instead of no-boil. I let it cook on the stove a bit longer, but other than that, followed the recipe. Soooo goood. I was skeptical of the coconut milk and I was wrong. Its delicious!
Awh good, I am so happy you loved this one Amy! Thank you!
I was looking for a skillet lasagna recipe and saw yours…What a great idea!! It was really delicious and so less-time consuming! Definitely a keeper! ThANK YOU SO MUCH:-):-):-)
Yay, so happy it was good! Thanks for making it Marianne!
Looks fantastic!!?
Thank you!
Seriously, Tieghan.. How do you just improvise and create stuff like this?! Made it – best. lasagna. ever. Thanks for sharing. Such an incredible talent 🙂
I don’t know! But i’m so happy you like them (: Thank you Rayna!
Hi. I am planning on making this this week. Several people have commented that they like the Coconut Milk in the recipe, but I can’t see that ingredient in the list. Any idea on if and how much I should add, and when?
Hi Liz! Use the coconut milk in place of the milk, so 1 cup of coconut milk. Please let me know if you have any other questions. I hope you love this recipe. Thank you!
Hello, do the lentils have to be soaked, or are they just dried lentils that have brown cleaned/rinsed? Thank you, looks delicious and I want to try it.
Just dried lentils, no need to soak. Please let me know if you have other questions. Hope you love this recipe! Thanks! 🙂
Hi! 2 questions…
1. Should the lentils be cooked or uncooked when you add?
2. If I can’t find “no boil” lasagne noodles, could I use regular and pre-boil them a bit?
Hi! Use uncooked lentils and yes just pre-boil the noodles. HI! That size bird will need to cook for 4 1/2-5 hours. Please let me know if you have other questions. Hope you love this recipe! Thanks! ?
Made this skillet lasagne for our Valentines dinner. It was amazing !!!! So filling and so cheesy. I will be making this again.
Thank you Jackie!
This is a great recipe! Just one question; what is a jar pasta sauce in ml, ounces or cups?
Thank you!
Thank you Nicole! It is usually about 24 ounces! I hope you love this!
Can’t wait to try. Lentils to use are dried?
Yes, I use dried lentils. Please let me know if you have other questions. Hope you love this recipe! Thanks! 🙂
Made this and it was great. Nice mix of flavors and like that it has lentils in it. Also like to use cast iron skillet. Your recipes are so creative and good even with the substitutions that I have learned to make to keep calories low but flavor high. The ingredients and herbs you recommend do make a recipe unique and flavorful.
I am so glad you enjoyed this Frances! Thank you so much, I hope you continue to love my recipes!
I made this tonight using barilla gluten free lasagna noodles. Usually I can tell when I use gluten free pasta but I couldn’t in this. Absolutely delicious! Now to convince my kids…
Haha that is so great! I am really glad you liked this Catherine!
This is my week-end go to recipe. Absolutely delicious and easy to make. I have made it several times, even with regular cooking spinach pasta and it works well too, just adding a little more water to the sauce. Yummy!
Thank you! I am so glad you enjoyed this Claire!
Great recipee I was unsure but once everything is done it’s comes together like gravy on potatoes …I will definitely make this again soon
I am so happy to hear that! Thank you Renea!
Hello, juszt wanted to mention, I liked this article.
It was funny. Keep on posting!
Thank you!
My brother suggested I would possibly like tbis web site. He was once entirely right.
This post actually made my day. You cann’t consider simply how so much time I had spent for this information! Thank you!
Thank you so much!
Congratulations on getting this recipe for skillet lasagna put on the Huffington Posts – The Best Instagram Recipes From 2018!!
Woohoo!! Happy New Year!
Thank you so much Barbara! Happy New Year!
This looks fabulous and would be great for a pot luck. Question: can I use skim mile or do I need heavier milk for this to come out? TIA
Hey Judy! I’d recommend using whole milk, but skim does work too if that’s what you prefer. The sauce will just be a little thinner. Please let me know if you have any other questions. I hope you love this recipe! Thank you! xTieghan
Made this for a Wednesday night dinner and it was a real crowd pleaser for my teens! Keep inquiring us with your creative recipes and beautiful photography. Just pre-ordered your next cookbook.
Thank you!! I hope you love the new cookbook, Sheryl! Also, so glad this recipe turned out so well for you! xTieghan
What type and size of skillet did you use in this recipe? What brand did you use for – jar roasted garlic or tomato basil pasta sauce? Im looking forward to making this. Looks delicious. Thanks!
Hi there! I use a 12-inch Staub cast iron skillet. I use DeLallo brand pasta sauce. Please let me know if you have any other questions. I hope you love this recipe! Thank you! xTieghan
In these crazy times, I found this dish.What a joy it was to make and eat.It was so much fun looking at your pages.Made my day and made me smile.Thank you
Thank you so much Michelle! xTieghan
I love this recipe. It’s so quick, simple, and delicious. The method works with any ingredients. I’ve used it with frozen vegetables, have added sausage, have used plain tomato sauce and just added spices, have used fresh mozzarella, the list goes on and on. One issue I do have is the lasagna noodles sticking together since they’re so flat, I think I’ll try this with some fresh pasta next time since it should cook in the same amount of time. I think it would be just as delicious with any type of noodle. Thanks so much for this recipe!
Hi Kelly! I am so glad this recipe turned out so well for you! Also, I am sure it will taste amazing with any noodle! Thank you so much! xTieghan
I have made this recipe so many times, I use whatever vegetables I have on hand. I threw in some leftover ratatouille and it worked this last time. What a winner. I feel like it’s lighter than regular lasagna, too, and takes much less time. Great recipe, as usual.
Thank you so much Lori! I am really happy this recipe turned out so well for you! xTieghan
This is one of the best veggie lasagnas I’ve ever had and I’m a vegetarian! I’m making it tonight for the second time and it’s going to be a go-to week night meal from now on. It’s so easy & delicious and with just two of in the house there’s left overs. It’s also one of the vegetarian meals I make that my husband will eat. Thanks for sharing!
Thank you for trying this Millie! I am really glad this turned out so well for you! xTieghan
Hi, thank you for the recipe, any idea to replace mushrooms in vegetarian or vegan recipes?
thank you so much
Lena
Hey Lena,
You could use another veggie that you enjoy! I hope you love the recipe, please let me know if you have any other questions! xTieghan
Excellent! Better than meat lasagna and flavors blend so well! I did forget the spinach, but still excellent!
Hey Jackie,
Thanks so much for giving the recipe a try. I am so glad that it was enjoyed!! xTieghan
I made this and it was really good. The prep time was a lot longer.. lots of stuff to chop I guess? And the cook time was longer too.. those darn lentils! In the end.. it was enjoyed by all and I will make it again. Thank you!
Hey Lydia,
Thanks so much for giving the recipe a try. I am so glad that it was enjoyed!! xTieghan
I have made this recipe several times….and each time I forget just how good it is! Delicious and easy….Yum!
Hey Laure,
I am so glad the recipe was enjoyed, thank you for making it! xTieghan
This a great base recipe….add or subtract what you have/want to put in and presto! I added a few marinated artichokes/sun dried tomatoes and sweet red pepper /eggplant/zucchini that I pan roasted in the oven. I will try the lentils next time. I omitted the milk. I added lots and lots of fresh basil at the end and served it over ww rotini. The fresh spinach made it special. My daughter-in-law is begging for more…she absolutely loved it.
Hey Melinda,
Fantastic!! Love to hear that this recipe was enjoyed, thanks a lot for making it! Have a great Sunday:) xxTieghan
Looks amazing but make sure you find alternative cheeses to provolone and parmesan. These both contain meat rennet.
Hey Mark,
You can use any cheese you like here. I hope you love the recipe! xTieghan
