    Why You'll Love This Recipe

    • This recipe is super easy, and is made in one pot!
    • And the ingredients are simple and easy to find.
    • This Cauliflower Red Lentil Soup is completely vegan and uses no cream, so anyone can enjoy it!
    • It is packed with flavor and plant-based protein.

    Ingredient Notes

    Ingredients for making this recipe in small bowls on a marble surface.

    Cauliflower: I live to use cauliflower in unexpected ways from Cheesy Vegan Cauliflower Casserole to Vegan Cauliflower Steaks. I used an entire small head of cauliflower here.

    Spices: Coriander, cumin, paprika give the Cauliflower Red Lentil Soup a delicious flavor.

    Red Lentils: Red lentils add creaminess, protein and a nice flavor.

    Vegetable Stock: I love to use Better Than Boullion. Make sure that it is lower sodium vegetable stock so your soup doesn't become too salty.

    Instructions

    Cauliflower florets cooking in a large Dutch oven.

    Step 1. First, heat extra virgin olive oil in a large Dutch oven over medium heat. Add the cauliflower florets, cumin, coriander and paprika.

    Season the cauliflower with a pinch of salt and pepper and sauté until the cauliflower is browned in some places and starts to soften, about 10 minutes.

    Step 3. Now, add the red lentils, vegetable stock and a pinch of red pepper flake and stir.

    Bring the mixture to a boil, then reduce the heat to low. Place the lid on the pot and simmer the soup for 20 minutes.

    Step 4. After 20 minutes, remove the cauliflower red lentil soup from heat and add lemon juice and non-dairy butter.

    Then, use an immersion blender to blend the soup smooth and serve with an extra drizzle of extra virgin olive oil and a sprinkle of chives.

    Recipe FAQs

    How should I store this Vegan Cauliflower Red Lentil Soup?

    Store the soup in the refrigerator for up to four days.
    Or freeze for up to a month for a quick and delicious freezer meal.

    What is the difference between lentils and red lentils?

    Green and brown lentils retain their shape and texture through cooking while red lentils have become mushy. Red lentils also cook faster!

    Do red lentils need to be soaked?

    No! Red lentils cook in about 20 minutes, no soaking necessary.

    Expert Recipe Tips

    If you like some texture in your soup, stop blending before the Cauliflower Red Lentil Soup is completely smooth.

    Do not substitute green or brown lentils in this recipe!
