  • Total Time: 45 minutes
  • Yield: 6 1x


Units Scale
  • 1 cup cooked brown lentils
  • 1 regular egg or 1 vegan egg*
  • 1/4 cup roasted sunflower seeds
  • 1 cup chopped mushrooms
  • 1/4 cup almond flour
  • 2 minced or crushed garlic cloves
  • 2 tablespoons chopped onion
  • 1 tablespoon olive oil
  • 1/2 teaspoon sea salt
  • 1/4 teaspoon ground black pepper


  1. Preheat your oven to 350°F. Line a baking sheet with parchment paper and set aside.
  2. Combine the lentils, egg, sunflower seeds, mushrooms, almond flour, garlic, onion, olive oil, salt, and pepper in the base of a food processor.
  3. Process on high for about 45 seconds, stopping once or twice to scrape down the sides. The lentils should be broken down almost completely.
  4. Transfer the mixture to a mixing bowl and then use your hands to form six patties. Don’t worry if the mixture is very wet, it will firm up as it bakes. 
  5. Place the baking sheet in the oven for 35 minutes or until the tops are golden brown, flipping the patties once during the baking process.
  6. After 35 minutes, remove the baking sheet and let the patties cool for a few minutes before serving. 


  1. VEGAN: *replace the egg with a flax egg made by combining 1 tablespoon of ground flax with 3 tablespoons of water. Let the mixture sit for 10 minutes to thicken before using. 
  2. Be sure to use green or brown lentils for this recipe. Do not use red or yellow lentils.
