Roughly chop onion, garlic, and cilantro to give your food processor a head start!
Rinse and drain the canned black beans. Add the black beans to a food processor along with the roughly chopped red onion, garlic, cilantro, sriracha, mayonnaise, cumin, soy sauce, and pepper. Pulse the ingredients until they are evenly mixed, but still slightly chunky.****
Transfer the black bean mixture to a bowl and add one large egg and 1 cup breadcrumbs. Stir the ingredients together until they're evenly combined. Let the mixture sit for about 5 minutes.
Divide the black bean mixture into six equal portions, then shape each portion into a patty, about 3.5 inches in diameter, ½-inch thick. Every time I make these, one patty has equaled exactly ½ cup! Just put it into a measuring cup and use that as a starting point for shaping the patties.
To cook the black bean burgers, heat 1Tbsp cooking oil in a skillet over medium heat. Once the oil is hot, add a few of the burgers and cook for about 4-5 minutes on each side, or until they are well browned and heated through. Repeat with more oil and the rest of the patties until they're all cooked.
Place each patty in a bun (see notes), add your favorite toppings, and enjoy!
*Feel free to sub parsley for the cilantro.**Don’t like Sriracha? Replace it with 1 Tbsp tomato paste to maintain the moisture in the patties, then add ¼ tsp chili powder or smoked paprika for extra flavor. I wouldn’t replace the Sriracha with the dry spices alone, as this will make the black bean mixture drier. ***To make these burgers vegan, make one flax egg and swap the mayo. Combine 1 Tbsp ground flaxseed with 3 Tbsp hot water. Let it sit for 5-10 minutes, stirring every few minutes, until thick, gel-like, and able to cling to a spoon. This replaces the 1 large egg in the recipe. To make the burgers fully vegan, also use vegan mayonnaise and choose vegan buns and toppings. ****You can make these without a food processor, but it's a whole lot easier with one. :) To make without a food processor, just finely mince the red onion, garlic, and cilantro, then mash the beans(either with a fork or with a potato masher) and stir in the Sriracha and remaining ingredients.Use any hamburger buns you enjoy! I like brioche buns when I can find them at a good price, but regular white, sesame, or whole-wheat buns also work. For sturdier buns, place them cut-side down in a dry skillet for 1-2 minutes, or directly on the grill for about 30 seconds, until lightly golden. Toasting the cut sides helps the buns hold up to the patty, sauce, and toppings.
