Everything on their menu at Active Culture is vegetarian or vegan, and we love popping in there now and then to enjoy breakfast or a burger!

While many vegetarian burgers can become dry and crumbly, these Lentil Burgers are tender, creamy, and rich.

Cilantro Aioli Sauce

Delicious served with a cilantro aioli sauce.

It’s easy to make your own homemade cilantro yogurt-based aioli sauce, which really adds flavor to the lentil burger!

The secret is in the sauce! Here are the ingredients for aioli sauce:

  • Garlic powder + paprika
  • Cilantro
  • Lime
  • Mayonnaise + Plain yogurt
  • Salt

  • 1/2 lime, juiced (about 2 Tbsp)
  • 1 tsp lime zest
  • 1 tsp turmeric
  • 1.5 Tbsp ground masala
  • 1 tsp of paprika
  • 1/4 tsp of ginger powder
  • 1 Tbsp cumin
  • 1 tsp coriander
  • 2 cups mushrooms, chopped finely by hand or in a food processor
  • 1 c parsley, finely chopped
  • 1 c feta, crumbled
  • Salt to taste
  • Olive oil

Cilantro aioli

  • 3 tsp garlic powder
  • 1/2 tsp paprika
  • 1/4 c cilantro, finely chopped
  • 3 tsp lime juice, plus 1 tsp zest
  • 1/2 c mayonnaise
  • 2 Tbsp plain yogurt
  • 1/4 tsp salt

Additions

  • Brioche Buns
  • Avocado
  • Microgreens

Instructions

  • Preheat oven to 375 degrees F.
  • In a small bowl, combine all ingredients for the aioli: cilantro, lime juice, paprika, salt, yogurt, mayonnaise, and garlic powder. Mix until well combined and set aside.
  • Bring a medium pot of water to a boil and add 1 Tbsp of salt. Reduce the heat to a simmer (medium low). Add lentils and simmer uncovered for 12-15 minutes. Cook until el dente and tender, then drain under cold water and rinse. Set aside.
  • Coat a large skillet with 2 Tbsp olive oil and heat over medium-high heat. Add in chopped mushrooms and cook until they release their liquid (6-8 min). Salt and pepper to taste, then reduce heat to medium-low. Add onions and garlic, and cook until translucent, 8-10 minutes. When onions and mushrooms are tender, remove from heat and allow to cool.
  • In a large bowl, combine the onion mixture, lentils, tomato paste, egg, all remaining spices, lime juice and zest, bread crumbs, and sweet potatoes. Mix until all ingredients are well incorporated. Fold in parsley and feta at the end and mix gently, stopping when ingredients are well dispersed.
  • Scoop 1/3 heaping cup into your hands and flatten out into a 1’’ thick patty (note* wet your hands with water or a little oil to prevent sticking). Place on a well-oiled, foil-lined baking sheet. Bake for 22 minutes in the oven.
  • Serve lentil burgers on a brioche bun with a spread of cilantro garlic aioli, avocado, and micro greens.
