What Are Split Red Lentils?

Red lentils are easily spotted in the legume section of the grocery store due to their orange pinkish color! They are quick cooking, do not need soaking, and are perfect for quick cooking soups.

And they are so cheap!

While, red lentils can be purchased as whole, most stores carry only split red lentils which is what you will need for this recipe.

If the package indicates it is a whole red lentil, skip purchasing as that requires a different cooking time.

These small legumes are naturally gluten free, packed with fiber and plant based protein plus many other vitamins and minerals!

They are sweet and slightly nutty and their texture breaks down in soup to almost a creamy consistency.

  • No soaking: Lentils and split peas can be cooked from dried with no need to soak first.
  • Other lentils: Yes, you sure can but keep in mind the consistency will be less blended. Neither green nor brown lentils break down as red lentils do. As well as cooking time may change.
  • All water: You can use all water instead of vegetable broth if that’s all you have. Just might add a bit more seasoning after.
  • The kettle trick: If you choose to use water and bouillon cubes, to save time, boil water in a kettle while prepping ingredients.
  • Creamier: Use an immersion blender to blend part of the soup for a creamier consistency.
  • Squeeze of lemon: Before serving, add a squeeze of lemon juice to brighten all flavors.
