Sandwiches of any kind are one of the foods I struggle with most when it comes to photography. It’s stupid, but because I struggle with them so much I always avoid sharing any kind of sandwich recipe. I literally cringe at the thought of photographing them. The fear of an ugly food photo stops me in my tracks.

I know, I know, stupid. But hey, look at me today! Here I am with my favorite quinoa burger. I can’t say I find these photos gorgeous, but it’s a burger, and it may never be gorgeous. The brothers said they looked good, Mom said they look good. So I’m trusting their opinions and sharing despite what I think.

Point is that these burgers have been a favorite since the very, very beginning of HBH. And with the Super Bowl on Sunday, I obviously had to share them…these really are the BEST quinoa burgers.

Yes, these burgers are EVERYTHING. And that’s not an exaggeration in the least, they just have so much going on. These are what we call the “epic” crispy quinoa burger. Crispy, cheesy burgers topped with melted Gruyere cheese, buttery beer caramelized onions, spicy-sweet potatoes fries, fresh herbs, and even a little avocado.

Everything about this recipe is SO GOOD. These are not your average quinoa burgers.

The burger details…

Here is what I will say, this is not my most “super simple” recipe. But nothing about making these burgers is hard. There are a handful of steps, and you do need to have a little time to make them. But you can do so much ahead of time, and trust me, the extra time in the kitchen is worth it.

Start with the burgers themselves. They’re made up of quinoa, white beans, bread crumbs, and egg. The key to creating the best quinoa burger? The combination of the spices and cheese in the burgers themselves. You have to give them flavor, so I use a touch of chipotle chili powder and plenty of sharp cheddar cheese.

Form the quinoa mix into patties and keep them covered in the fridge while you prepare the sweet potato fries.

Now for those sweet potato fries…

They’re simply the best thing to ever be put on top of a burger. Dramatic, but true.

I like to cut my fries super thin and skinny and then toss them with a mix of chili powder and smoky paprika. Roast in the oven until crisp on the outside, but still soft in the center. Fair warning, these fries are addicting. You might just double the recipe. Some for the top of the burger and some to snack on.

Just a thought…

Sweet Potato Fries

Ah, and those beer caramelized onions…

Yes, you need these too, because you can never go wrong with caramelized onions. I know it seems like a bit much, but go with me on this.

Using beer to caramelize the onions not only adds additional flavor right into the onions but it also helps them to cook down and caramelize faster. If you love caramelized onions, you will love these onions even more. They’re truly so good, even onion haters enjoy them.

Once the onions are cooked, the fries are ready, and the burgers have been crisped in the skillet, it’s assembly time. Find your favorite buns, toast them up, then add a cheesy burger to each bun. Add the beer caramelized onions and sweet potatoes. At this point, you could be done. OR you can take the burger a step further with mashed avocado, a fried egg, and fresh herbs.

Do what you’d love most here, completely up to you as to how you finish these. Just be sure not to skip the onions or the fries. These are two key toppers that you really do NEED.

A few tips…

The burger patties themselves don’t need to be put in the fridge for chilling. I just recommend doing so while you make the fries. If you need to cook these up right after forming, that works just as well.

You can make the burgers up to four or five days in advance and keep in the fridge. Or you can freeze them for up to four months

If you don’t enjoy cooking with beer, just caramelize the onions without the beer following these directions.

These make for a fun Monday dinner. Or plan to make them on Sunday for the Super Bowl. Either is great, but once you make these, my hope is that you’ll be making them on repeat throughout the year! They’re healthy(ish), easy(ish), and so very delicious.

Fingers crossed you all love them as much as we do!

Calories 559 kcal


Quinoa Burgers

  • 2 cups cooked quinoa
  • 1 cup cannellini beans mashed
  • 1/2 cup Panko bread crumbs
  • 1 large egg, beaten
  • 1 clove garlic, minced or grated
  • 1 teaspoon chipotle chili powder
  • kosher salt and black pepper
  • 3/4 cup shredded sharp cheddar cheese
  • 1/2 cup shredded gruyere cheese
  • 6 burger buns, toasted
  • fried eggs, mashed avocado, and herbs, for serving (optional)

Sweet Potato Fries

Beer caramelized onions

  • 2 tablespoons salted butter
  • 2 large yellow onions, thinly sliced
  • 1 cup beer, such as pumpkin, lager, or pilsner


  1. 1. In a medium bowl, combine the quinoa, mashed beans, Panko, egg, garlic, chili powder, cheese, and a pinch each of salt and pepper. Form the mix into 5-6 equal burgers. Place on a plate, cover, and transfer to the fridge.

    2. To make the fries. Preheat the oven to 425 degrees F. Place the sweet potatoes on a large baking sheet and toss with olive oil, chili powder, paprika, and a large pinch each of salt and pepper. Spread the fries in an even layer. Do not overcrowd the pan, if needed, divide the fries between 2 baking sheets Transfer to the oven and bake for 15-20 minutes, then flip and bake for 15-20 minutes more. You want the sweet potatoes to be tender, yet crisp. 

    4. Meanwhile, make the onions. Melt the butter and onions together in a large skillet over medium-high heat. Cook, stirring occasionally until softened, about 5 minutes. At this point, you want to slowly add the beer, 1/4 cup at a time, until the beer cooks into the onions. Continue to cook another 8-10 minutes until you've used all of the beer and the onions are deeply caramelized. Remove the onions from the skillet to a plate.

    5. Cook the burgers in the same skillet, heat a drizzle of oil over medium-high heat. When the oil shimmers, add the burgers and cook until golden and crisp, about 5 minutes per side. During the last minute of cooking add the Gruyere cheese, cover, and cook 2-3 minutes, until the cheese has melted.

    6. To assemble, place each burger on a bun, top with caramelized onions and sweet potatoes. If desired, add a fried egg, mashed avocado, and fresh herbs. ENJOY.

Recipe Notes

To Make Ahead: the burgers can be formed and kept in the fridge for up to 1 week. Cook as directed. 

Freezing: the burgers can be frozen in an airtight container for up to 4 months. To cook, thaw on the counter for 1-2 hours, then cook as directed. 

Baking Instead of Pan Cooking: you can bake the burgers on an oiled baking sheet at 425˚ for 20 minutes, flip and continue baking for another 5-10 minutes, until crisped. Note that you will not get as crispy of a burger this way.
