Ingredients

  • Red Lentils: This soup is made for red lentils though you can substituted brown or green lentils with additional cooking time.
  • Diced Tomatoes: Any kind works but I like fire-roasted tomatoes for the best flavour.
  • Coconut Milk: I like light coconut milk in this recipe but you can also use full-fat coconut.
  • Broth: Any homemade stock or store-bought vegetable broth is suitable.
  • Sweetener: The recipe calls for a touch of coconut sugar which is lovely alongside the spices, it’s optional but I really like adding a little sweetness to curry recipes…sub with maple syrup if you like!

This list is not complete. Please see the recipe card at the end of the post for the complete ingredient list with measurements and detailed instructions.

  • Add up to 1 tsp red pepper flakes or 1/2 tsp cayenne pepper for some heat.
  • Add up to 1 tbsp peeled and grated fresh ginger.
  • Use garam masala or red curry paste instead of curry powder for a variation.
  • A squeeze of lime or lemon juice is nice to finish the recipe or brighten up leftovers.

Yes, this soup freezes well. Let it cool then store in a freezer-safe container or heavy duty freezer bag for up to 3 months. Thaw frozen soup in the fridge overnight then reheat on the stovetop or in the microwave in individual portions.

Yes, though it will have a different colour and texture. You’ll need a bit longer cooking time for green or brown lentils and may need a little extra liquid but you can add that as you go to adjust the thickness as needed.

    I made this last night for dinner. It was absolutely amazing! I only had a small can of tomatoes and used half a can of coconut milk. I also cooked this in my instant pot, throwing everything in at the same time except for the coconut milk, I stirred that in at the end. The flavor profile in your recipe is spot on and restaurant worthy. This is a keeper and one I will make on rotation. Yum, yum,, yum.
