Ingredients

Scale
  • 1 cup cooked brown lentils
  • 1 tbsp olive oil
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 8 oz mushrooms, finely chopped
  • 1/2 tsp salt
  • 1/2 tsp black pepper
  • 1 tsp smoked paprika
  • 1 tbsp soy sauce
  • 1 tbsp tomato paste
  • 1/2 cup rolled oats
  • 1/4 cup breadcrumbs
  • 1 tbsp ground flaxseed + 2.5 tbsp water (flax egg)
  • Cooking spray or additional olive oil for frying

Instructions

  1. Prepare flax egg by mixing ground flaxseed with water. Set aside for 5 minutes to thicken.
  2. Heat olive oil in a skillet over medium heat. Sauté onion for 3–4 minutes until translucent.
  3. Add garlic and chopped mushrooms. Cook for 7–8 minutes until moisture is released and evaporated. Season with salt, pepper, and smoked paprika.
  4. Stir in soy sauce and tomato paste. Remove from heat and let cool slightly.
  5. In a large bowl, mash cooked lentils slightly, leaving some texture.
  6. Add mushroom mixture, oats, breadcrumbs, and flax egg. Mix until well combined.
  7. Form into 4–6 patties and chill in the fridge for 20–30 minutes to firm up.
  8. Heat a skillet with a little oil over medium heat. Cook patties for 4–5 minutes per side until browned and heated through.
  9. Serve on buns with your favorite toppings and condiments.

Notes

  • Use a food processor for a finer texture, but don’t overprocess.
  • Great for meal prep—freeze uncooked patties for up to 3 months.
  • Can be baked at 375°F (190°C) for 25 minutes, flipping halfway.
  • Gluten-free oats and breadcrumbs can be used for a gluten-free version.
