What is a Lentil Burger?

A lentil burger is simply a meatless, vegetarian patty made with cooked lentils and other vegetable ingredients. I like to use 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 vegetarian 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.

Recipe Steps

Making lentil burgers is pretty easy, especially if you have cooked lentils on hand. I have a whole blog post on how to cook lentils, so you might want to check that out.

Step One

To make the burgers, simply combine the ingredients in a food processor. Process on high until the lentils are broken down, about 60 seconds.

Step Two

Form the mixture into patties and bake.

Step Three

Enjoy hot.

Are Lentil Burgers Healthy?

Lentil burgers are really healthy! They have fiber and nutrition from the lentils, plus all wholesome ingredients. I think you are really going to love these. Plus, they have no processed, icky ingredients like fake meats do.

Each of these lentil patties has approximately:

  • 200 kcal
  • 7.5 grams fat
  • 24 grams carbohydrate
  • 1.2 grams sugar
  • 4.5 grams fiber
  • and 11 grams pure plant protein!


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 I didn’t use 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.
