½ cup
corn kernels, fresh, frozen and thawed, or canned and drained
4 slices
pepper Jack cheese, (optional)
4
burger buns
½ cup
chipotle mayo
Romaine lettuce leaves
1 cup
caramelized onions
Method
Preheat the oven to 325°F with a rack in the center position. Spread the black beans in an even layer on a parchment-lined sheet pan and bake until dry, 12 to 15 minutes.
Heat 1 tablespoon of the olive oil in a large skillet over medium heat until glistening. Add the onion and jalapeños and cook, stirring often, until the vegetables begin to soften, about 3 minutes. Add the garlic and cook until fragrant, about 1 more minute. Remove from the heat and let cool slightly.
In the base of a food processor, combine the carrot, cilantro, cumin, onion powder, salt, paprika, chili powder, egg, breadcrumbs, and the onion-jalapeño mixture. Blend until everything is fully combined. Add the corn and dried black beans and pulse until the mixture looks combined but some beans are still intact, 8 to 10 times.
Heat the remaining 2 tablespoons olive oil in the same large skillet over medium heat until glistening. Wet your hands and divide the bean mixture into 4 patties about 1 inch thick and 3 inches across. Add to the skillet and cook until golden brown and crisp, about 3 minutes. Flip and repeat on the other side. During the last minute, top the burgers with cheese, if using.
Toast the burger buns and spread each with 2 tablespoons chipotle mayo. Add romaine lettuce and 2 tablespoons caramelized onions. Transfer the burger patties directly to the prepared buns and top with the remaining bun halves. Serve immediately.
