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.

Why You Need This Recipe

  • This recipe uses mushrooms, onions, spices, and almond flour, in addition to cooked brown or green lentils.
  • Most plant-based burger recipes use oats or breadcrumbs as one of the main ingredients, but this version is oat-free and 100% grain-free. I used almond flour instead of breadcrumbs.
  • 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.

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 or breadcrumbs, 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.

Recipes Tips & Substitutions

  • 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.
  • Add a slice of vegan or regular sliced cheddar right when they come out of the oven for a gluten-free lentil cheeseburger.
  • You can freeze these lentil burgers. Once completely cool wrap the patties in plastic wrap and freeze. Once ready to eat heat in a 350 degree oven until warmed through.
