How do you make veggie burgers stick together?

The key ingredient that helps bind these vegan veggie burgers together is actually oat flour. That’s why we’re not using any eggs nor ground flaxseed eggs to help them bind.

 The lentils and chickpeas help a bit, but the real binding agent is in the oats. This is because oats contain a starch that’s made up of amylopectin, which when activated with water, creates a “glue-like” texture.

This is why oat flour can sometimes be swapped in for regular all-purpose flour. The glue-like texture can act very similarly to gluten!

Using oat flour also helps keep these vegan mushroom burgers entirely gluten-free, as well, making them suitable for all eaters!

Vegan Lentil Mushroom Burger Ingredients

As we noted earlier, these veggie burgers are made from just 6 simple pantry staple ingredients. From your kitchen, you’ll need the following:

  • Lentils: You can cook the lentils or purchase them pre-cooked. You’ll need about 1 cup of cooked lentils, which I used about 1/2 cup of dried lentils to cook. 
  • Chickpeas: For even more protein. Save the aquafaba to make an awesome vegan chiffon cake later on!
  • Rolled oats: this is what we’ll make the oat flour from. Use gluten-free certified as needed.
  • Mushrooms: any type of mushroom is good here! We’re just using them for the overall texture. I used shiitake mushrooms. 
  • Coconut aminos: you can also use soy sauce or Tamari soy sauce for gluten free, but I tried to keep this recipe both nut-free and soy-free to be super allergy friendly for all.
  • Garlic: For flavor. You can also add in sautéed onions or onion powder. 
  • Tomato paste: This will also help give our veggie burgers flavor. 
  • Sea salt

You’ll notice that these lentil veggie burgers are not only packed with both plant protein and veggies, but they’re naturally eggless, dairy free, nut free, grain free, and soy free.

How to make vegan burgers from scratch

These vegan lentil burgers are incredibly easy to make. In fact, you only need a food processor or high speed blender and a sauté pan. 

For the actual cooking of the veggie burger, you can use a baking sheet or the grill.

The full written recipe and ingredient measurements are found down below in the recipe card. However, we’re going to go over the basics here, along with visuals to help you make the BEST veggie burgers around. Seriously, people will be asking you for the recipe!

To make these veggie burgers:

  1. Begin by sautéing the mushrooms. You want them to be fully cooked, as they’ll be more easily blended into the burger patty mixture. You’ll use the coconut aminos here to give the mushrooms flavor.
  2. In a food processor, pulse the oats into a flour. Then add in the remaining ingredients (lentils, chickpeas, tomato paste, and mushrooms), and blend until you reach a thick and consistent patty batter.
  3. Form burger patties using about 1/2 cup per each patty. You’ll yield 5 medium-large patties. Form them into patties and either place them onto a parchment lined baking sheet or a plate to be grilled.
  4. If cooking in the oven, bake for 20 minutes at 375, then flip the patties to cook for another 5 minutes. If grilling, you’ll grill them for about 4-6 minutes on each side.
  5. Serve and enjoy!

Pro tip: if you want to make these vegan cheese burgers, after flipping the burgers the first time, place a piece of vegan cheese (I love Violife’s sliced cheese!) on top and cook the burgers for the remaining 5 minutes.

How to grill a veggie burger

The burger patty itself is sturdy enough that it can easily be grilled without falling apart.

You’ll simply heat the grill as you normally would, and grill them as you would a regular burger patty.

One important topic to note: if you are truly vegan, and where you’re grilling the veggie burgers is not entirely vegan, be cautious about grilling. Actual meat may have touched the grill, and depending on how well they clean their grills, there is the potential for cross-contamination.

If that’s the case, I recommend grilling these lentil veggie burgers (at least yours) on your own grill, and simply heating it in the oven for 5 minutes at 300F before serving. This ensures that there’s no chance for possible cross-contamination, and that your vegan veggie burger is truly vegan!

Storage tips

If you’re not consuming these mushroom lentil burgers right away, I recommend storing them cooked and in an airtight container in the fridge for up to 5 days. You can also freeze them cooked for up to a month!

To make ahead: if you’re grilling or cooking these veggie burgers the following day, you can make the patties the day before and store them in an airtight container. Chill them in the fridge overnight, then proceed to grill them.
