Ingredients You’ll Need
You’ll need a few simple ingredients for this Lentil Potato Soup:
- Onion, garlic, and carrots: the aromatic base that builds flavor.
- Tomato paste and optional tomato sauce: for color and tang.
- Green lentils (or a mix of green, black, and red split lentils — just not only red split, as they break down too fast).
- Red or yellow potatoes: diced small so they cook evenly. Sweet potatoes work too, though they’ll add a different flavor.
- Water or broth: vegetable broth adds richness, but water works if you season well.
- Herbs and seasonings: cumin, paprika, thyme, or parsley are all great options.
Optional add-ins like spinach or kale give a boost of greens at the end.
Best Lentils for This Soup
Green or brown lentils are ideal here. They hold their shape well while still turning tender and earthy. A mix of green, black, and red split lentils also works beautifully for variety in texture. Avoid using only red split lentils — they cook too quickly and can make the soup too mushy.
Best Potatoes for This Soup
Red or yellow potatoes are perfect because they stay firm and creamy without falling apart. If you prefer something sweeter, you can swap in diced sweet potatoes for a subtle twist. Just keep in mind they cook a bit faster, so check for doneness earlier.
How to Make Lentil Potato Soup
Step 1 – Sauté Aromatics
Start by heating a little oil in a large pot. Add chopped onion, garlic, and carrots. Sauté over medium heat for about 5 minutes until soft and fragrant.
Step 2 – Add Tomato Base
Stir in tomato paste and, if using, tomato sauce. Let them cook for a minute or two. This step deepens the flavor and gives the soup a rich base.

Step 3 – Add Lentils, Potatoes, and Liquid
Mix in the rinsed lentils, diced potatoes, herbs, and seasonings. Pour in the water or broth. Stir well so everything combines evenly.

Step 4 – Simmer
Bring to a boil, then reduce to a gentle simmer. Cover and cook for 35–40 minutes until the lentils and potatoes are tender. Stir occasionally to prevent sticking.

Step 5 – Finish and Serve
Check the potatoes with a fork for doneness. Adjust the seasoning with salt and pepper. For a creamy texture, you can blend part or all of the soup with an immersion blender. Serve warm with your favorite toppings.
This soup also works in a slow cooker — just combine everything and cook on low for about 6–7 hours, or on high for 3–4.
Cooking Tips and Adjustments
Add chopped spinach or kale at the end for color and nutrients. For a thicker consistency, mash a few potatoes right in the pot. To make it child-friendly, blend it smooth. Store leftovers in the fridge for up to 4 days or freeze for up to 2 months. When reheating, add a splash of broth or water to loosen the texture.
