Ingredients

  • 1 medium yellow onion diced
  • 3 cloves garlic roughly chopped
  • 1 heaping cup (200 grams) diced raw sweet potato (no need to peel)
  • ½ cup (60 grams) chopped walnuts
  • 1 cup (170 grams) cooked brown rice
  • 1 ¾ cups (275 grams) cooked brown lentils
  • cup (90 grams) ketchup
  • 3 tablespoons (21 grams) ground flaxseed
  • 1 tablespoon (15 grams) Dijon mustard
  • 1 teaspoon fine sea salt
  • ¼ teaspoon ground cayenne pepper
  • ¼ teaspoon freshly ground black pepper
  • ¾ (90 grams) cup yellow cornmeal

Instructions

  • Preheat oven to 450°F with a rack in the center. Line a baking sheet with parchment paper.
  • Into food processor fitted with the blade, place the onion, garlic, sweet potato and walnuts. Process until finely chopped.
  • Add the cooked rice and lentils and pulse until well combined.
  • Transfer into a large mixing bowl.
  • Add the ketchup, flax, mustard, salt, cayenne, and black pepper. Mix together thoroughly.
  • Stir in the cornmeal.
  • Shape into eight patties and place on the baking sheet.
  • Bake for 20 minutes, then flip each patty and bake 15 minutes more.

Notes

  1. You'll need about ¾ cup dry lentils to make 1 ¾ cups cooked. I usually make a larger batch and use the remainder for another meal.
  2. You'll need to use about ⅓ cup dry to get the cup of cooked rice called for in this recipe. Here, too, I usually make a larger batch and use the remainder for another meal.
  3. Burgers keep well in an airtight container in the fridge for a week or in the freezer for a year.
  4. Reheat in the microwave or wrapped in foil in the oven or toaster oven.
