Ingredients and Substitutions
- Lentils: Use brown or green lentils (dried) for this recipe. Red lentils will get too mushy.
- Onion: I like to use a sweet or yellow onion, but you can sub red onion or shallots.
- Carrots: Use fresh or frozen.
- Ginger: Fresh ginger adds a ton of flavor to coconut lentil soup. If you don’t have fresh, try ginger paste (sold in tubes or jars at most stores) or frozen crushed ginger cubes.
- Garlic: Fresh garlic will contribute the most potent flavor, but dried minced garlic or garlic powder will work in a pinch.
- Cumin: Substitute mild curry powder if that’s what you prefer.
- Diced tomatoes: Use a can of fire-roasted and a can of regular or all fire-roasted if you want more flavor.
- Coconut milk: Use the unsweetened, full-fat kind that comes in a can, such as Thai kitchen brand.
- Vegetable stock: You can use chicken stock if that’s what you have and if you don’t mind the soup not being vegan.
- Lime juice: Lemon juice works as a sub.

Combine all of the ingredients except the lime juice in a slow cooker.

Cook on high for 4 to 7 hours or low for 6 to 9 hours until the lentils are soft and veggies are tender.
Equipment
Use a slow cooker that is at least 4.5 quarts in size. Larger ones, such as the popular 7 quart Crock-Pot work even better.
Storage and Reheating
Coconut lentil soup will last for up to 5 days when stored in an airtight container in the refrigerator. For best results, reheat in a saucepan over medium heat, stirring occasionally, until warmed through. You can also reheat it in the microwave in 1-minute intervals, stirring between them.
To freeze this soup, let it cool completely then transfer to freezer-safe containers. Seal tightly, label, and freeze for up to 3 months. if you want to freeze individual portions, use Souper Cubes!
Let frozen soup thaw in the fridge overnight before reheating. If you need to reheat it from frozen, put it in a pot with a lid over medium heat until warmed through. Stir frequently to promote thawing and to prevent scorching.

Notes
- The cooking time will largely depend on the age and efficiency of your slow cooker and the age of the beans. I have an old slow cooker that’s not very big, so it took about 6 hours on high to get soft lentils and tender vegetables.
- Store leftovers in an airtight container in the fridge for up to 5 days. Reheat in a pan over medium heat, stirring occasionally, until warmed through or in the microwave in intervals.
- To freeze, let the soup cool completely. Transfer to freezer-safe containers, leaving an inch of headspace, or Souper Cubes (if you want to freeze individual portions). Seal tightly, label, and store for up to 3 months. Thaw in the fridge overnight before reheating. To reheat from frozen, put the soup in a pot with a lid.
