Sweet Potato Black Bean Burgers are the perfect way to use up a leftover baked sweet potato. You don’t even need a food processor to make them!
Ingredients You’ll Need
Featuring canned beans and mashed sweet potato, this veggie burger recipe is naturally gluten-free and vegan. If you don’t keep oat flour on hand, you can make it at home by simply blending oats in your blender.
Paired with oat flour and BBQ sauce, these burgers have plenty of flavor without a hefty list of spices. For a grain-free option, you can use ground flax seed instead of oat flour with similar results.
If you prefer a different flavor profile, try adding a squeeze of sriracha for spice, or add in chili powder or smoked paprika for a smoky flavor.
How to Make Sweet Potato Black Bean Burgers
Preheat the oven to 350ºF. Rinse and drain the canned black beans, then spread them out in a single layer on a large, rimmed baking sheet.
Place them in the oven for 15 minutes to remove any excess moisture. Once they start to split, remove the pan from the oven and set it aside.
Meanwhile, heat the olive oil in a skillet over medium-high heat. Sauté the onion until softened, about 5 minutes, then add in the garlic and stir for one more minute. Remove from the heat.
In a large bowl, combine the sauteed onion and garlic, cooked black beans, sweet potato, oat flour (or ground flax seed), BBQ sauce, cumin, and salt.
Use a fork to stir the mixture, mashing the beans to help the batter stick together.
You don’t want to mash all of the beans, as they help add texture, but you want it mashed enough that you can form and shape the burger patties. The batter will be relatively sticky.
Use a 1/3 cup measure to scoop the black bean mixture and drop it onto a large baking sheet lined with parchment paper. Use your hands to flatten the mixture and shape it into a burger patty about 3/4-inch thick. (Use wet hands to prevent sticking, if necessary.)
This recipe should make 8 to 9 burgers.
Bake the burgers at 350ºF for 20 minutes, then use a spatula to gently flip them over and bake for another 5 to 10 minutes. The finished burgers will feel a little dry around the edges, but still slightly soft to the touch in the center.
As they cool, they will firm up and dry out a bit more, so don’t overcook them.
Serve warm on your favorite hamburger buns with lettuce, tomato, red onion, and any other toppings you love. Sauteed peppers or creamy avocado are also excellent additions.
Storage: Leftovers can be stored in an airtight container in the fridge for up to a week, or in the freezer for up to 3 months. The burgers will be slightly drier when reheated, so I recommend adding a good sauce on top for moisture.

- ¼ cup BBQ sauce (see notes)
- ½ teaspoon ground cumin
- ½ teaspoon fine sea salt

You don't want to mash all of the beans, as they help add texture, but you want it mashed enough that you can form and shape the burger patties.
- Using the same baking sheet from earlier, line it with parchment paper. With a 1/3 cup measure, scoop the black bean mixture and place the mound on the prepared baking sheet. Use your hands to shape it into a burger about 3/4-inch thick. (Wet hands will help prevent sticking, if necessary.) This recipe should make 8 to 9 burgers.

Would I be able to take out the BBQ sauce? I’m not a fan of BBQ sauce or tomato paste.
It helps with binding and flavor, but you could probably use a little water and season the mixture to your taste to replace it.
Okay Thank you!!!
I love making these burgers. My husband and I are trying to eat vegetarian meals and this is a great one. We have a vegan friend coming to visit today so I have these made and ready for us to enjoy.
I cannot eat black Bean. Can I use something else ?
Another type of bean would probably work, otherwise I would search for a recipe using ingredients that you know you can have.
I love love love this recipe! Have made it 3x!
I’m so happy to hear that! Glad you’re enjoying them. 🙂
These look so good! Unfortunately I can’t eat oat flour or flax seeds. Would almond flour work? Thank you!
Hello,
I was wondering…If i wish to have additional protein added to this recipe, could i had a scoop of pea protein as a binder to the mixture?
Thanks a bunch
Do you have to soak the beans before you put them into the oven?
Thank you!
Thank you for a terrific recipe. I couldn’t find a BBQ sauce at the store that wasn’t loaded with sugar so I searched my pantry for a sub and tried tomato pesto. Loved the flavor.
Your black bean burgers are absolutely delicious. Thank you for the great and easy recipe!
It says 1/2 yellow corn. Do you mean 1/2 Cup?
Are you referring to the yellow onion? I use half of a yellow onion, and in parentheses after that I mention that it’s roughly 1 cup chopped. Hope that helps!
Do you like these better than your speedy black bean burgers?
Right now I do, but I still LOVE those Speedy ones, too! Austin likes these more I think because of the chunky texture and the BBQ sauce flavor. But if you have kids who like veggies & beans to be more disguised, the speedy ones work better in that case.
I’m asking if the recipe is calling for half a cup of corn because it says 1/2 corn
In the ingredient list? Sorry, I’m not seeing that in this recipe.
I love how easy these burgers are to make! The BBQ sauce is genius for adding extra flavor.
