Made with dry red lentils (a complete guide to lentils here) and simple pantry staple ingredients, it’s definitely the perfect meal to make on a tight budget. I often make a batch or even a double batch and freeze some for later. That way I have easy meals to grab for lunch or dinner. It’s filled with anti-inflammatory turmeric, fiber, protein-rich lentils, and potassium-packed potatoes, creating a soup that’s both healing and delicious.
If you’re not feeling this flavor combination but still want a soup, this vegan split pea soup or coconut curry soup instead.

What Goes Into This Recipe
The ingredients you will need to make a bowl of lentil potato soup may already be in your cabinet! Let’s look at the main ingredients you will need.
Substitutions and Variations
Sometimes you want to change things up. Here are some tried and true swaps you can make when preparing potato lentil soup.
- Lentils: For a creamier soup stick with the red lentils or you can swap with yellow lentils which have a similar texture and mild flavor. While you can also make this soup with any lentils including, green, brown and even black, these other varieties of lentils may require a longer cooking time and will turn your soup a different color.
- Cumin: If you don’t have whole cumin seeds, you can substitute with ground cumin but use two teaspoons of ground instead of one tablespoon of seeds.
- Coconut milk: Adding coconut milk is completely optional but it adds a nice sweeter flavor, mellows out the spices and adds more creaminess to the soup. You can also use other plant-based milks but they will not be as thick and creamy as the canned coconut milk. Just be sure to use a plant milk with a mild flavor.
- Want it spicy? Add in some cayenne pepper, red pepper flakes or some sliced chilies.
How To Make Potato and Lentil Soup
Step 1: Heat the oil in a large dutch oven or soup pot. When heated, add the cumin seeds and toast them for about 1 to 2 minutes. Keep a close eye on them and don’t let the cumin seeds burn.
Step 2: Add the onion, garlic, and ginger. Cover with a lid and cook over medium-low heat for 2 to 3 minutes until the onion begins to soften.
Step 3: Add the potatoes and red lentils and stir to coat them with spices and oil. Add the broth to a pot and bring to a gentle simmer.
Step 4: Cover with the lid and cook over medium-low heat for 15-20 minutes until potatoes and lentils are very soft and mashable. Add salt, black pepper, and turmeric to taste. Stir in coconut milk, if using. For a creamier soup, blend the soup using an immersion blender or a regular blender working in batches until you reach desired consistency.
TOP TIP: Blending vegan lentil potato soup is completely optional! You get great flavor when it’s served as a chunky soup or when blended. If you swap out the lentils and use green or brown, this soup will work much better served up chunky.
Toni’s Tips
- For a creamy potato lentil soup, add the optional can of coconut milk.
- Puree the soup by pulsing the immersion blender or regular blender to leave the soup with a bit of texture.
- Adjust the seasoning to your own taste.
- Serve it up with some freshly made jalapeno cornbread or vegan focaccia bread.
FAQs
You don’t need to soak lentils for soup or other recipes. They cook rather quickly so this step is not necessary.
Any lentils work well for soup, but in this recipe, the texture and mild flavor of red and yellow lentils really work best. Personally, I enjoy brown and green lentils in chunky soups and red or yellow lentils in creamy soups. Here’s a great guide to lentils you can check out to learn more!
How to Store
- Make ahead: Red lentil potato soup is perfect for meal prep. After cooking the soup, transfer it to containers to fit the desired number of servings and allow the soup to cool completely. Then cover and store in the fridge or freezer.
- Storage: Store in the fridge for up to five days and in the freezer for up to three months.
- Reheat: Allow the frozen soup to thaw out in the fridge overnight. Transfer the amount you wish to serve and heat on the stove for 5-8 minutes over medium heat until heated through. You can also microwave smaller amounts of the soup until hot. If the soup seems a bit thick add more vegetable broth, coconut milk, or water to thin it out a bit.
