A lentil burger is simply a meatless, vegetarian patty made with cooked lentils and other vegetable ingredients. It’s a nice alternative to regular burgers, and this homemade version is healthier than the packaged ones. This recipe uses mushrooms, onions, spices, and almond flour, in addition to cooked brown or green lentils.

Most plant-based burger recipes use oats as one of the main ingredients, but this version is oat-free and 100% grain-free.

These delicious Lentil Burgers can also be made vegan by replacing the egg that binds the ingredients. For the vegan option, I recommend using a flax egg which is made by mixing together 1 tablespoon of ground flax seed with 3 tablespoons of water. I have noted that substitution in the printable recipe that you can find below.

FAQs

What do lentil burgers taste like?

Lentils burgers have a mild flavor that goes well with typical burger toppings, such as lettuce, pickle, onion, tomato, mustard, ketchup, or whatever you like with your burger.

My recipe doesn’t have a ton of texture since it didn’t include oats, but the outside of the burger is crisp and the inside is moist and tender.

Can I use red lentils for this recipe?

I highly suggest using only brown or green (not the French kind) of lentils for this recipe. Red or yellow lentils will be too mushy.

What can I serve with baked lentil burgers?

You can serve whatever you like with a lentil burger, including a fresh green side salad, sweet potato fries, or whatever you like. I also like to make an easy tahini drizzle to go with the lentil burgers. To make the tahini sauce, just mix a few tablespoons of tahini with a tablespoon of warm water and some fresh lemon juice.

Ingredients

  • 1 cup cooked brown lentils
  • 1 regular egg or 1 vegan egg*
  • ¼ cup roasted sunflower seeds
  • 1 cup chopped mushrooms
  • ¼ cup almond flour
  • 2 minced or crushed garlic cloves
  • 2 tablespoons chopped onion
  • 1 tablespoon olive oil
  • ½ teaspoon sea salt
  • ¼ teaspoon ground black pepper

Instructions

  1. Preheat your oven to 350°F. Line a baking sheet with parchment paper and set aside.
  2. Combine the lentils, egg, sunflower seeds, 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. 

Notes

  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.
