How to Make Sweet Potato Black Bean Burger

You can find the full printable recipe, including ingredient quantities, below. But first, here are some explanations of ingredients and steps to help you make this recipe perfect every time.

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.

What You Need

Here’s what you’ll need for this sweet potato burger recipe:

  • Sweet potato — You’ll need a medium sweet potato, roughly 5 inches long and 2 inches wide.
  • Oatmeal — We’re using oatmeal instead of bread crumbs to keep these burgers gluten-free. If you prefer breadcrumbs substitute it in the same quantity.
  • Walnuts — A great, healthy fat option
  • Black beans — You’ll need one 15-ounce can of black beans or 1 3/4 cup cooked black beans.
  • Seasoning — I like adding taco seasoning to give the burgers a zesty flavor, but you can use any of your favorite seasonings here.

Step-by-Step Instructions

Here are more detailed step-by-step instructions:

Step One: Prepare the Sweet Potato

The first step is to cook your sweet potato. Here’s how to do it:

  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.
    Ingredients plus spices for these black bean burgers are in a food processor.
  2. Pulse until a coarse flour is developed, leaving texture of the ingredients
  3. Stir in the frozen corn to distribute it equally throughout the batter.
    Frozen corn is added to the veggie burger batter.
  4. 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.

The patties will firm up even more as they cool. So making them ahead of time and allowing them to come to room temperature before serving them is ideal.

Why This Recipe is a Winner

  • Using dehydrated onions minimizes the moisture that can cause bean burgers to be gummy, while still adding delicious flavor
  • Adding walnuts contributes healthy plant-based fats
  • Using oats instead of breadcrumbs keeps this recipe gluten-free while adding binding that keeps this veggie burgers firm.

Marly’s Tips

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

  • Use a rubber spatula to push down ingredients from the side of the the food processor bowl.
  • 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

Prep Time: 20 minutes
Cook Time: 10 minutes
Total Time: 30 minutes
Servings: 6
Calories: 195kcal

Ingredients

  • 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

Instructions

  • 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.

Notes

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.

    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!!
