Instructions

  1. Place lentils and water or vegetable broth in a medium saucepan and bring to a boil. Reduce heat to low, cover, and simmer for 20-25 minutes until lentils are tender but not mushy. Drain excess liquid and let cool slightly.
  2. While lentils cook, heat 1 tablespoon olive oil in a skillet over medium heat. Sauté onion, garlic, carrot, and celery for 5-7 minutes until soft and fragrant. Set aside to cool.
  3. In a large bowl, lightly mash cooked lentils with a fork, leaving some texture.
  4. Add sautéed vegetables, walnuts, ground flaxseeds, oat or almond flour, tamari, smoked paprika, cumin, pepper, and salt. Mix until combined and the mixture binds well. Add more flour if too wet.
  5. Cover and refrigerate for at least 30 minutes to firm up for shaping.
  6. Divide mixture into 6 equal portions and form into 3/4-inch thick patties.
  7. Heat remaining 1 tablespoon oil in a non-stick skillet over medium heat. Cook patties 4-5 minutes per side until golden brown and heated through, flipping carefully.
  8. Serve warm on gluten-free buns or lettuce wraps with your preferred toppings and condiments.
  9. Store leftovers in airtight container in refrigerator up to 4 days or freeze patties individually for up to 3 months.
