How to Make Sweet Potato Black Bean Burger

It’s pretty easy to make these sweet potato burgers, so let’s get started!

  1. Cook the sweet potato in a microwave until tender.
  2. Pulse oats and walnuts in a food processor until a coarse flour forms. 
  3. Add the sweet potato and remaining burger ingredients (except the corn) to the food processor. Pulse in short bursts to create a batter with some texture.
  4. Stir in the frozen corn and let the mixture sit for 5 minutes.
  5. Form patties and place them in a heated skillet and cook until browned on both sides, around 5 minutes.
  6. Place the cooked burgers on a baking pan and bake for about 10 minutes.
  7. Serve on toasted buns with your favorite toppings.

Here are more detailed step-by-step instructions:

Step One: Prepare the Sweet Potato

The first step is to cook your sweet potato.

  1. Wash the potato to remove any dirt.
  2. Prick it with a fork several times.
  3. Place it in the microwave and cook it for 2 to 3 minutes, until tender.

Step Two: Create the Burger Batter

  1. Place the oats and walnuts in a food processor and pulse until a very coarse flour is developed. It’s ok if you see bits of oatmeal; it will add texture.
  2. Chop up the cooked sweet potatoes and pulse that until smooth.

  3. Drain the beans and add them to the food processor along with the seasonings.
  4. Stir in the frozen corn to distribute them equally throughout the batter.
    Frozen corn is added to the veggie burger batter.
  5. Let the mixture sit for a few minutes for the oats to soak up the moisture.

Notice I don’t add any salt. Canned beans have salt already, so no need to add any extra.

Step 3: Cook the Patties

  1. Form the sweet potato veggie burgers dough into patties (6 thinner patties, or 4 larger patties).
  2. Cook them in a skillet over medium-high heat until browned on both sides (about five minutes each side).

  3. I like to sprinkle salt pepper on the uncooked side of the burgers.
  4. Place the browned burgers in a heated oven and cook for around 10 minutes to help the burgers set and become firm.

Marly’s Tips

Here are some tips for making this sweet potato black bean burger recipe perfect every time:

  • You may need to use a spatula to help stir the ingredients in the food processor.
  • You can freeze sweet potato and black bean burgers. Cook the burgers and allow them to cool and then transfer to a freezer bag or container and freeze for up to 2 months.
  • If you’re using a low salt taco seasoning, you can add additional salt to the burger batter, up to a 1/2 teaspoon.
  • Use different seasonings for variety, such a mesquite-grilled seasoning or spicy chipotle.
  • To grill these burgers, skip the skillet and bake the patties for about 10 minutes, and then grill them. This helps them firm up so they will grill nicely.

Frequently-Asked Questions

Are black bean burgers good for you?

Yes, the majority of black bean burgers are good for you. That’s because they’re made with black beans, vegetables and grains. Black beans are loaded with fiber, potassium, folate, and a whole host of other important phytonutrients.

Can I freeze black bean burgers?

Freezing black bean burgers is one of the things I love about making them homemade. I prefer to make a double batch and then freeze half. The recipe below yields 4 to 6 burgers (depending on the size of the burgers), so you can expect anywhere from 8 to 12 from a double batch.

There’s no end to delicious toppings for veggie burgers. What’s your favorite veggie burger topping? Is it onion rings? Something unusual? Leave it in the comment below!

Gluten-Free Bean Burgers

It’s great that these bean burgers are gluten-free. Even if you don’t have sensitivities, it never hurts to give your body a break from gluten.

In fact, the wheat consumed 50 years ago is different than the wheat we eat today. Wheat was re-engineered so it would produce larger yields. As a result, some people claim that today’s wheat is harder on your body.

I’m not celiac, I do consume some gluten, but my priority is to minimize it in my diet.

That’s one reason I used oatmeal in this recipe instead of bread crumbs. And it’s a good thing I experimented with that because it’s my new favorite gluten-free veggie burgers ingredient.

  • 1 medium sweet potato
  • 1 cup oatmeal
  • ¼ cup chopped walnuts
  • 15 oz black beans (canned) rinsed and drained
  • 1 tablespoon dehydrated onions
  • 1 teaspoon garlic powder
  • 1 tablespoon taco seasoning (See note on salt)
  • 1 tablespoon nutritional yeast flakes
  • 1 tablespoon ground flax seeds
  • ¼ cup frozen corn


  • Scrub and wash the outside of a sweet potato. Use a fork to stab the potato several times and then place it in the microwave and cook for two minutes. Use oven sits to remove from the oven and allow it to cool. After it's cooled, chop into large cubes.
  • Place the oatmeal and walnuts in a food processor and pulse until a coarse flour is formed. 
  • Add the cubed sweet potatoes, drained black beans, onions, garlic powder, taco seasoning, nutritional yeast flakes, and ground flax seeds. Pulse for a couple of seconds and then use a spatula to push the ingredients back down. Pulse again for several seconds. It's good to leave some texture in the burgers so don't puree it down to a paste, just creating a cohesive mass.
  • Add the frozen corn and use a spatula to stir it throughout. Let that mixture sit for about 5 minutes.
  • When you're ready to cook the burgers, turn your oven to 200°F and spray a skillet with vegetable cooking spray. Place the skillet over medium to medium-high heat. Form patties and place them in the heated skillet using a spatula.
  • Cook patties for about 5 minutes on one side. Sprinkle salt and pepper on the uncooked side of the patties. Flip the patties and cook on the other side until the patties have firmed up and are brown on both sides.
  • Place the cooked burgers on a baking pan and place that pan in your heated oven or toaster oven. Repeat cooking any remaining veggie patties using the process described above until all the burgers are cooked, allowing each about 10 minutes to stay in the oven before serving.
  • Serve on toasted buns with dairy-free mayo, pickles, onions, and sliced tomatoes.

Recommended Equipment

(The products above contain sponsored links to products we use and recommend)


If your taco seasoning is a low-salt variety, you may choose to add a 1/2 teaspoon of sea salt or a teaspoon of mild miso paste to this recipe, depending on your taste preferences. We try to keep added sodium to a minimum.
I like to reserve a few whole black beans to add to the mix with the corn to add visual interest to the final black bean burgers.

      Hi Maggie. See above. The word “miso” has been removed from the text of the recipe. The ingredients are correct.

    This sounds so delicious! I noticed miso is listed in the directions but not in the amounts.

    This was a great burger!!! Had a white sweet potato (Japanese) already cooked so used that and omitted the corn. (not a fan in a burger). Pan fried for dinner and stored the rest for later. Better warmed the next day even!! Thanks Marly!!
