This easy lentil soup is a family favorite (along with spinach lentil soup) and it reheats beautifully!

Red Lentil Soup Recipe

Red lentil soup is incredibly filling and highly nutritious. Its cousins vegetarian lentil soup and chicken lentil soup are in our regular rotation and kids do not mind at all! We all need a good healthy soup to bring back some balance to our lives from time to time!

The flavours of onion, garlic, cumin and coriander in this red lentil soup recipe will fill your kitchen with incredible aromas. Make a big batch and freeze some for later. Be sure to pack the rest away for lunch throughout the week. It reheats beautifully just like lentil curry does (with a splash of stock or water). Lentils hold their shape so well!

Packed with fibre and iron from the lentils and quinoa, this nutrient-dense soup is delicious and makes a great choice for an easy weeknight dinner! And may I suggest this lentil casserole with mushrooms – so much health and flavor right there!

Ingredients for Red Lentil Soup

  • Mirepoix: A marriage of diced onions, carrots and celery and, in this case, minced garlic cooked slowly. This acts as the flavour foundation of many different soups.
  • Oil: Olive oil, coconut oil are great choices. Ghee, which is a clarified butter will also work well.
  • Spices: Cinnamon, coriander and salt.
  • Red pepper flakes
  • Lentils: Dry and rinsed.
  • Quinoa: Uncooked.
  • Broth: Water and low sodium bouillon cubes or any store bought (or homemade) low sodium broth.

How to Make Red Lentil Soup

  • Prep: Preheat dutch oven or big pot and add oil to coat the bottom.
  • Saute: Add the onion and garlic and begin to saute, stirring occasionally.
  • Add: Add celery and carrots and continue to stir. Add spices and red pepper flakes and continue to cook, stirring frequently.
  • Boil: Add red lentils, quinoa and broth. Bring to a boil and cover to cook.
  • Serve: Serve hot with a side of sprouted grain bread, low carb biscuits or cauliflower breadsticks and juicy tomato mozzarella salad (why not?!).


  • No soaking: Lentils and split peas can be cooked from dried, unlike beans. However, if you own magic Instant Pot you can cook even dried beans without soaking. Ha!
  • Green or brown 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.
  • All broth: You can use all broth in place of water if you would prefer.
  • The kettle trick: If you choose to use water and bouillon cubes, to save time, boil water in a kettle while prepping ingredients.
  • Taste as you go: Adjust the salt to your liking. Not all bouillon cubes are created equal!
