These vegan sweet potato and black bean burgers are smoky, spicy and a little bit sweet! A delicious crowd-pleasing veggie burger recipe that's super easy to make and perfect for everything from cookouts to busy weeknights.
Preheat the oven to 400°.
Scrub the sweet potato and poke a few holes in it with a fork or sharp knife. Place the sweet potato directly on the oven rack and bake it until easily pierced with a fork, about 45 to 60 minutes (Note 2). Leave the oven on.
Cut the sweet potato open and let it cool for a few minutes when it's done baking.
Place the oats into the bowl of a food processor fitted with an s-blade. Blend them to a coarse powder.
Scoop out 1 cup of the sweet potato flesh and place it into the food processor with the ground oats (Note 3). Add the beans, onion, garlic, chipotle, adobo sauce, cumin, cilantro, and salt.
Run the machine for a few seconds at a time, scraping the sides and bottom of the bowl with a rubber spatula between runs. Continue until the ingredients are blended but still have some texture.
Taste-test the mixture and make adjustments as needed, adding more chipotles, adobo sauce, or salt if needed.
Line a baking sheet with parchment paper.
Shape the mixture into 6 patties (Note 4) and place them on the baking sheet. The mixture will be very soft at this point, but the burgers will firm up when you bake them.
Bake the patties for about 30 minutes, carefully flipping them halfway through, until lightly browned.
Stuff the patties into buns and top them with toppings of choice. Serve.
