Ingredients

  • 1 cup walnuts
  • 1 cup old-fashioned rolled oats
  • 15 oz. can black beans
  • 3/4 cup yellow onion, diced
  • 2 Tbsp. tomato paste
  • 2 Tbsp. tamari
  • 1 Tbsp. vegan Worcestershire sauce
  • 2 tsp. Dijon mustard
  • 1 tsp. onion powder
  • 1 tsp. ground cumin
  • 1/2 tsp. garlic powder
  • 1/2 tsp. smoked paprika

For serving:

  • Whole grain buns (GF if desired)
  • BBQ Sauce
  • Lettuce, onion, tomato, etc.

Instructions

  • Oven: Preheat oven to 375°F (190°C). Line a baking sheet with parchment paper and set aside.
  • Prepare patties: In a large food processor, add walnuts and oats. Pulse until a medium-fine crumble forms. Dice onion and add to food processor. Then add all other seasonings & ingredients except black beans. Pulse/blend to combine, scraping down sides if needed.
  • Add beans: Rinse and drain black beans. Gently pat dry with a paper towel to remove excess moisture. Add beans to food processor. Pulse a few times to incorporate. (The mixture will be very dense, and it's okay to leave the beans chunky.) It takes a little patience, and you may have to stop a few times to scrape down the sides with a spatula to help encourage the mixture. (If you don't think your food processor can handle this, slightly mash the beans in a separate bowl. Then add the pulsed walnut/oat/spice mixture to the mashed bean bowl and stir well to combine.)
  • Shape: Carefully remove the S-blade from your food processor. Then scoop out the mixture into 5 even balls. Shape into patties, and place on lined baking sheet. (For me, the mixture is about 1.4lbs. So I measure out five heaping "quarter pounders" of .28lbs each.)
  • Bake: Place in oven and bake for 15 minutes. Flip the patties, then bake 15 more minutes. Let rest 5-10 minutes before serving to firm up even more if desired. Assemble burgers on buns topped with BBQ sauce or other toppings of choice.

Notes

For gluten-free: Ensure your oats and Worcestershire sauce are GF. Then use your favorite GF buns, or serve atop fresh greens.
Spicy version: Add cayenne pepper, chili powder, chipotle pepper, etc.
Yield: Recipe makes 5 large patties. (Or 4 jumbo patties or 6-7 smaller patties.)
Nutrition: Estimated nutritional content is calculated for the patties only (without buns, BBQ sauce, and toppings).
