Hearty Lentil and Potato Soup is a comforting bowl full of warm flavors and satisfying textures. The soft, creamy potatoes blend perfectly with tender lentils, making it a filling meal that feels like a hug on a chilly day. It’s the kind of soup that’s simple but packed with goodness and a little bit of earthiness from the lentils.
I love making this soup when I want something healthy but still need a little extra warmth and comfort. One tip I always follow is to cook the lentils and potatoes until they’re just right—soft enough to melt in your mouth but not falling apart completely. It makes the soup feel nice and thick without being heavy.
My favorite way to enjoy this soup is with a slice of crusty bread on the side. It’s perfect for dipping and soaking up all the flavors. Honestly, it’s one of those easy meals that everyone in my family asks for again and again, especially on cooler evenings when you want something cozy and nourishing.
Key Ingredients & Substitutions
Lentils: Brown or green lentils work best here because they hold their shape well. Red lentils cook faster but can turn mushy, which changes the texture. For a quicker meal, red lentils are a fine choice.
Potatoes: Starchy potatoes like Yukon Gold or Russet are great for this soup. They soften nicely and add creaminess. If you want less starch, try red potatoes, but the soup may be less thick.
Vegetable broth: This adds flavor, but you can use water if you want a lighter base. For more depth, try adding a vegetable bouillon cube or a splash of soy sauce.
Herbs and spices: Thyme adds earthiness, while cumin gives a warm touch. Feel free to adjust or leave out cumin if you prefer a milder taste.
How Can I Get the Perfect Texture for Lentils and Potatoes?
The key is to cook the lentils and potatoes until tender but still holding their shape. Here’s how:
- Start with rinsed lentils to remove dust and debris.
- Dice potatoes evenly so they cook at the same rate.
- Simmer the soup gently after boiling to avoid breaking down ingredients too fast.
- Check tenderness at about 25 minutes—lentils and potatoes should be soft but not mushy.
- If you want a thicker soup, mash just a portion gently, then stir it in for creaminess without losing all texture.
Following these tips helps the soup feel hearty and rich, with just the right balance of soft and bite-sized pieces.
Equipment You’ll Need
- Large soup pot – big enough to hold all the ingredients and cook evenly without spilling.
- Wooden spoon – perfect for stirring the soup gently without scratching your pot.
- Knife and cutting board – essential for chopping potatoes, carrots, and onions safely and easily.
- Measuring cups and spoons – to get your lentils, broth, and spices just right.
- Ladle – helps serve the soup without making a mess.
Flavor Variations & Add-Ins
- Add chopped spinach or kale near the end of cooking for a boost of color and nutrients.
- Swap potatoes for sweet potatoes to add a hint of sweetness and extra vitamins.
- Include diced smoked sausage or bacon if you want a meaty, smoky flavor.
- Stir in a splash of lemon juice or vinegar before serving to brighten the flavors.

- 1 medium onion, finely chopped
- 2 cloves garlic, minced

- 1 tsp dried thyme

How Much Time Will You Need?
This soup takes about 10 minutes to prepare and roughly 30 minutes to cook. Total time is about 40 minutes, which includes prepping the vegetables and simmering until tender and tasty.
Step-by-Step Instructions:
1. Sauté the Aromatics:
Heat the olive oil in a large pot over medium heat. Add the chopped onion and cook, stirring occasionally, until it becomes soft and translucent—about 5 minutes. Add the minced garlic, dried thyme, and cumin (if using), and cook for another minute until fragrant.
2. Add Lentils and Vegetables:
Stir in the lentils, diced carrots, and potato cubes. Mix everything well so the flavors start blending together.
3. Simmer the Soup:
Pour in the vegetable broth (or water) and add the bay leaf. Raise the heat to bring the soup to a boil. Once boiling, lower the heat to a gentle simmer and cook uncovered for about 25-30 minutes. The lentils and potatoes should be tender but still hold their shape.
4. Finish and Serve:
Remove the bay leaf. Taste the soup and add salt and freshly ground black pepper as needed. If you want a thicker texture, gently mash some of the potatoes and lentils with a spoon or potato masher, then stir it all together. Ladle the soup into bowls, garnish with fresh parsley, and add a spoonful of yogurt or sour cream if you like. Serve warm, ideally with crusty bread on the side.
Can I Use Red Lentils Instead of Brown or Green Lentils?
Yes, you can! Red lentils cook faster and tend to become softer and more mushy, which will give the soup a creamier texture. Just reduce the cooking time to about 15-20 minutes and keep an eye on them to avoid overcooking.
How Can I Store Leftover Lentil and Potato Soup?
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm gently on the stove over low heat, stirring occasionally. If the soup has thickened too much, add a little water or broth to loosen it up.
Can I Make This Soup Vegan?
Absolutely! Just skip the yogurt or sour cream garnish or use a plant-based alternative. The rest of the recipe is naturally vegan-friendly.
Is It Possible to Freeze Lentil and Potato Soup?
Yes, this soup freezes well. Let it cool completely, then store in freezer-safe containers for up to 3 months. Thaw overnight in the fridge before reheating on the stove.
