Instructions
PREHEAT OVEN AND PREP PAN: Preheat the oven to 400F. Line a rimmed baking sheet with parchment paper or lightly coat it with Olive oil spray and set aside.
DRAIN AND RINSE BEANS: Open and drain one 15 ounce can black beans (about 1 1/2 cups), one 15 ounce can chickpeas (about 1 1/2 cups), and one 15 ounce can white beans (about 1 1/2 cups). Rinse each can under cold running water until the water runs clear, about 30 seconds per can. Shake off the extra water and set the colander in the sink so the beans can dry while you cook the vegetables.
SAUTE VEGETABLES: Heat 2 tablespoons extra virgin olive oilin a large skillet over medium heat until the oil shimmers and flows easily across the pan, about 1 minute. Add 1/2 medium red onion, diced (about 1/2 cup), 1 medium red bell pepper, diced (about 1 cup), and 1 medium jalapeno pepper, seeded and diced (about 1/4 cup). Cook, stirring occasionally, until the vegetables are soft, the onion is translucent, and the edges start to turn golden, 5 to 7 minutes.
ADD GARLIC AND OLIVES: Stir in 5 cloves garlic, minced (about 1 1/2 tablespoons) and 1/4 cup canned black olives, drained and diced. Cook until the garlic is fragrant and just starting to turn golden, about 1 minute. Remove the skillet from the heat and let the mixture cool slightly while you mash the beans, about 5 minutes.
MASH BEANS: Transfer the drained beans to a large mixing bowl. Use a potato masher to break them down until about two-thirds of the beans are mashed and the rest are still in small chunks. The mixture should hold together when pressed but still have visible bean pieces for texture.
MIX BURGER BASE: Add the cooled vegetable mixture to the mashed beans. Add 2 cups old-fashioned oats, 1 1/2 teaspoons smoked paprika, 1 1/2 teaspoons New Mexico chile powder, 1 tablespoon dried oregano, 1 tablespoon dried parsley, 1 1/2 teaspoons red pepper flakes, 1 1/2 teaspoons ground cumin, 1/2 cup Italian breadcrumbs, 1 teaspoon kosher salt, and 1/2 teaspoon fresh-ground black pepper. Pour in 6 large egg whites (about 3/4 cup). Use your hands to mix everything together until every piece is coated in egg white and the spices are evenly distributed, about 2 minutes. The mixture should feel moist and hold its shape when you squeeze a handful.
FORM PATTIES: Divide the mixture into 12 equal portions (about 4 ounces each if you have a kitchen scale). Shape each portion into a patty about 3/4 inch thick. The patties will feel soft and a bit fragile at this point, which is perfectly normal.
CHILL PATTIES: Place the patties on a plate or parchment-lined tray, cover with plastic wrap, and refrigerate for 30 minutes. This firms the patties so they hold their shape during baking and gives the oats time to absorb moisture from the egg whites.
BAKE VEGGIE BURGERS: Arrange the chilled patties on the prepared baking sheet in a single layer with a little space between each one. Bake for 15 minutes, then carefully flip each patty with a thin spatula. Bake for another 15 minutes until the outside is lightly browned and firm to the touch, about 30 minutes total.
SERVE: Serve the veggie burgers warm on buns with your favorite toppings, or enjoy them on their own alongside your favorite sides.
Notes
MAKE-AHEAD: Patties can be formed up to 1 day ahead and stored covered in the refrigerator before baking. The extra chill time actually helps them hold together even better.STORAGE: Cooked veggie burgers stay at peak quality in an airtight container in the refrigerator for 3 to 4 days. Safe to eat for up to 5 days, though the texture starts to soften past day 4.REHEATING: Reheat in a skillet over medium heat for 2 to 3 minutes per side until warmed through and the outside is crispy again. The oven works too: spread on a baking sheet and warm at 350F for about 10 minutes.FREEZING: Freeze cooked or uncooked patties for up to 3 months at peak quality, safe for up to 6 months. Place a piece of parchment paper between each patty so they stay separate, then store in a freezer-safe bag with the air pressed out. Defrost in the refrigerator overnight before reheating.INGREDIENT TIP: New Mexico chile powder is pure ground chile peppers, milder and sweeter than regular chili powder (which is a spice blend). Substitute with ancho chile powder for a similar heat level, or use half the amount of chipotle chile powder for a smokier kick. For Italian breadcrumbs in a pinch, mix 1/2 cup plain breadcrumbs with 1/2 tablespoon Italian seasoning.AIR FRYER VERSION: Preheat the air fryer to 375F. Place chilled patties in a single layer without touching (work in batches). Cook for 8 minutes, flip carefully, then cook another 6 to 8 minutes until golden brown and firm to the touch. The air fryer gives a crispier outside while keeping the inside moist.PAN-FRY VERSION: Heat 1 tablespoon olive oil in a nonstick skillet over medium heat until the oil shimmers. Cook chilled patties for 4 to 5 minutes per side until a golden crust forms and the burger is warmed through.
