  • 1 lb. sweet potatoes peeled, cut into ½-inch cubes
  • ½ cup quinoa rinsed and drained
  • 1 cup vegetable broth or water
  • 1 ½ tsp. cumin
  • ¾ tsp. paprika
  • ½ tsp. garlic powder
  • ¼ tsp. cayenne pepper
  • 1 ½ tsp. salt
  • ¼ tsp. pepper
  • 15 oz. black beans canned, rinsed and drained
  • 1 cup oats quick or old-fashioned, gluten-free
  • ½ cup sweet onion finely diced
  • ¼ cup cilantro finely chopped
  • 2 Tbsp. olive oil
  • Hamburger buns gluten-free*
  • Avocado or guacamole optional
  • Tomato thinly sliced, optional
  • Onion thinly sliced, optional


  1. In a medium-sized pot combine sweet potatoes, quinoa, and vegetable broth. Cover pot with a lid and bring to a boil. Reduce heat to a simmer and cook for 22-25 minutes, or until sweet potatoes are fork tender.
  2. In a small bowl combine cumin, paprika, garlic powder, cayenne pepper, salt, and pepper. Whisk to combine.
  3. Pulse oats in a high speed blender 3-4 times to make a coarse oat flour.
  4. Once sweet potatoes and quinoa are done cooking, add them to a large bowl with black beans, coarse oat flour, onion, cilantro, and seasoning mix. Mix until well combined. (You may have to use your hands for this!)
  5. Divide burger mixture into 8 equal portions. Form each portion into a round disc about 1 inch thick.

Stove top:

  1. Heat olive oil in a large skillet over medium heat. Place burger patties in a single layer. (You may have to cook these in 2 batches depending on the size of your skillet.)
  2. Cook patties for 4-5 minutes per side. 

In the Oven:

  1. Preheat oven to 400 degrees.

  2. Line a baking sheet with parchment paper.  Coat each patty with 1 teaspoon olive oil and place in a single layer on the baking sheet.

  3. Bake patties in preheated oven for 35-40 minutes, flipping halfway through.

  4. Serve sweet potato black bean burgers on gluten-free hamburger buns with avocado, tomato, and onion and enjoy!


  1. Heat grill to medium heat. Let fully heat for at least 10 minutes.

  2. Spritz a bit of non-stick cooking spray on the grill before adding patties.

  3. Cook patties for 5-6 minutes per side. Enjoy!

Recipe Notes

  • Nutritional information is for 1 patty without the bun.
  • Udi's hamburger buns taste great and can be found in most grocery stores! (That's what I used in this recipe.)
  • Schar's gluten-free buns have a really great texture, too.

Meal Prep and Storage

  • To Prep-Ahead: Make the patties completely and store in the refrigerator or freezer until ready to serve.
  • To Store: Store in an airtight container in the refrigerator for up to 4 days.
  • To Freeze: Place patties in a freezer-safe container with a piece of wax paper between each one. Freeze for up to 6 months.
  • To Reheat: When ready to reheat, add a bit of oil to a skillet and cook for a few minutes per side until heated through. You can also add them to a 300° oven for 10-15 minutes.

Expert Tips and Tricks

  • Rinse quinoa. This gets rid of the bitter saponins.
  • Make your own oat flour. Pulse oats a few times in a blender. This is a much healthier binder than bread crumbs!
  • Mush it together. If you're worried about them falling apart, smash the burgers together before forming into patties.
  • Get a good crusty sear. When cooking on the grill or skillet, wait to flip the patties until you have a nice crusty sear. This also helps to ensure the burger doesn't fall apart.
  • Freeze and save for later. This recipe makes enough for 8 patties. Freeze them and pull out later when you're craving a burger.
