- 1 1/2 cups hot water
- 1 cup red lentils
- 1 large onion, minced
- 1/4 cup chopped fresh cilantro
- 5 cloves garlic, minced
- 1 tablespoon spicy Dijon mustard, or more to taste
- 1 tablespoon ground cumin
- 1 teaspoon dried parsley
- 1 teaspoon garlic powder
- 1/2 teaspoon red pepper flakes
- 2 tablespoons all-purpose flour, or as needed
- cooking spray
- Combine water and lentils in a saucepan; bring to a boil and cook until the water is completely absorbed and the lentils tender yet holding form, 15 to 20 minutes. Transfer lentils to a large bowl and let cool.
- Stir onion, cilantro, garlic, mustard, cumin, parsley, garlic powder, and red pepper flakes into the lentils; add flour as needed to help absorb excess moisture and bind ingredients together. Shape lentil mixture into 4 patties.
- Prepare a large skillet with cooking spray and heat over medium heat.
- Cook burgers in the hot skillet until firm and hot in the center, 4 to 7 minutes per side.
