These “burgers” have it all when it comes to plants–food that comes from plants, like vitamin-rich red onions, carrots, parsley, and sun-dried tomatoes. Quinoa, tender brown lentils, and walnuts provide ample healthy plant protein, with chili powder and smoked paprika adding their gentle spice.

To bind all the ingredients together, to make them easier to shape into patties, we mix in an egg, flax egg or farm egg, and some oat flour. A simple blend of avocados, lemon juice and garlic salt is all it takes for the sauce.

Sometimes Robbie and I’ll scarf down our veggie burgers without the bun, with just the quick avocado sauce. Other times, we’ll sandwich our veggie burgers with whole wheat burger buns. Lentil quinoa veggie burgers with avocado sauce and homemade whole wheat buns–as Robbie would say, hook in and hold on!

Michael Pollan, the award-winning author of The Omnivore’s Dilemma, wrote, “If it came from a plant, eat it. If it was made in a plant, don’t.” So let’s bite into plants, plants masquerading as hamburgers, these life-giving lentil quinoa veggie burgers.

Lentil Quinoa Veggie Burgers recipe tips and tricks:

  • Keep it vegan: Use a flax egg. For one flax egg, mix 1 tablespoon ground flax seeds and 2 tablespoons warm water in a small cup or bowl. Set aside until the flax absorbs the water and becomes mucousy, 10 to 15 minutes.
  • Cook lentils and quinoa ahead so they are at the ready. Form the patties ahead of time too.
  • Veggie burgers like these are fragile–we can’t just plop these babies on the grill grates like a meat pattie. Cook them in a skillet. Once they’re golden brown on both sides, you can keep them hot right on the grill using a grill pan with small holes or slits in the metal. Grill pans are perfect for grilling anything small enough to fall through grill grates.
  • A 3-inch cookie cutter helps with shaping the veggie burgers. Fill the cutter with the lentil quinoa mix about 1/2 inch thick.
  • I shape them on a silicone baking mat so they don’t stick to the pan.

    Hi Letty,
    I am trying these burgers this week. What is the best way to cook lentils? Can I cook them in my electric pressure cooker? Reply · 14 July, 2016

    • Hi Lyn, Green lentils cook in 25 minutes without a pressure cooker. And 10-12 minutes in pressure cooker, quick release.

    Hi, can I substitute the oat flour with nutritional yeast. Reply · 17 February, 2018

    • HI Veronica,
      I don’t recommend substituting the oat flour with nutritional yeast because the oats are there to help bind all the other ingredients together. Adding some nutritional yeast to these veggie burgers is a wonderful idea. Love the flavor of nutritional yeast! Reply · 17 February, 2018

    I made these burgers today. We are plant based, gluten and oil free so I made them with flax egg and without oil and we ate them with lettuce buns. They were quite delicious. Thanks so much for sharing the recipe! Reply · 7 July, 2018

    • Thank you Sherry. Way to go with the changes to work with your diet! I am stoked to know you liked them! Reply · 7 July, 2018

  • Amanda

    Can I substitute almond flour for the oat flour? Reply · 27 December, 2019

    • Hi Amanda. The oat flour is there to absorb moisture. Kind of a gluten-free breadcrumb/panko. If gluten is not a problem, it would be better to sub in the breadcrumbs to help everything bind together. If you do end up subbing almond flour, let me know how it goes. Thanks, Letty Reply · 28 December, 2019
