Ingredients You’ll Need

Lentils & Vegetables

1 cup brown or green lentils, rinsed and picked over
- Brown or green lentils hold their shape nicely and stay hearty.
- Skip red lentils here, since they turn very soft and change the texture.
3 medium russet or Yukon gold potatoes, peeled and cut into 1/2-inch cubes
- Yukon gold potatoes give a creamier texture and slightly buttery flavor.
- Russets work great if you want a softer, thicker soup.
2 medium carrots, peeled and diced
2 celery stalks, diced
1 large yellow onion, diced
4 cloves garlic, minced
1-inch piece fresh ginger, minced or grated
- Use ginger paste from a tube if you want a shortcut.
1 can (14.5 ounces) diced tomatoes, with juices
- Fire-roasted tomatoes add a nice smoky note if you find them.

Fats, Liquids & Seasonings

2 to 3 tablespoons olive oil or avocado oil
6 cups vegetable broth or chicken broth
- Use low-sodium broth so you control the salt.
- In a pinch, mix water with a good quality bouillon paste.
1 to 2 tablespoons tomato paste
1 to 2 teaspoons harissa paste or 1 teaspoon smoked paprika
- Harissa gives gentle heat and depth.
- Smoked paprika works well if you avoid spice.
1 teaspoon ground coriander
1 teaspoon ground turmeric
1 teaspoon ground cumin
1 teaspoon dried thyme or Italian seasoning
1 bay leaf
1 to 1 1/2 teaspoons kosher salt, plus more to taste
1/2 teaspoon black pepper, plus more to taste
Juice of 1/2 to 1 lemon, to finish
- Bottled lemon juice works in a pinch, but fresh tastes brighter.

Optional Add-ins & Toppings

2 cups chopped spinach or kale
1/2 cup coconut milk or heavy cream, for a richer finish
Plain Greek yogurt or plain non-dairy yogurt, for topping
Fresh parsley or cilantro, chopped
Crushed red pepper flakes, if you like extra heat

Equipment

Large heavy-bottomed pot or Dutch oven (at least 5 to 6 quarts)
Cutting board and sharp chef’s knife
Wooden spoon or heat-safe spatula
Ladle
Measuring cups and spoons
Immersion blender (optional, for thicker texture)

Tips & Tricks

Rinse lentils under cool water and pick out any tiny stones or shriveled bits.
Cut potatoes into even cubes so they cook at the same rate and stay tender, not mushy.
Sauté onions, carrots, and celery until they turn lightly golden to build deeper flavor.
Toast spices in the oil for a minute or two to wake them up and boost aroma.
Use low-sodium broth and add salt in layers so the soup never tastes too salty.
Add leafy greens near the end of cooking so they stay bright and not overcooked.
Stir occasionally while the soup simmers so lentils do not stick to the bottom.
Adjust thickness by adding extra broth or water, or simmer longer to reduce.
Finish with lemon juice at the end to brighten flavors and balance the starchiness.
Taste before serving and tweak salt, pepper, and acid until the flavor pops.

How to Make Easy Lentil Potato Soup Recipe

Step 1: Sauté veggies and aromatics

Heat oil in a large stock pot or Dutch oven over medium heat. Once hot, add onions, carrots, and celery. Cook and stir until the vegetables soften and the onions turn translucent, about 7 to 8 minutes.

Stir in garlic and ginger and cook 1 to 2 minutes, until they smell fragrant. Add tomato paste and harissa (or smoked paprika) and cook another 1 to 2 minutes, stirring, so the tomato paste darkens slightly and tastes sweeter.

Step 2: Add spices, lentils, and potatoes

Sprinkle in coriander, turmeric, cumin, thyme, salt, and pepper. Stir so the spices coat the vegetables and toast for about 1 minute.

Add the rinsed lentils and potato cubes to the pot. Stir to coat them in the spiced vegetable mixture so flavor reaches every bite.

Step 3: Add liquids and simmer

Pour in the broth and the can of diced tomatoes with their juices. Add the bay leaf and stir everything together.

Raise the heat to bring the pot to a gentle boil. Once it boils, lower the heat to a steady simmer, cover the pot slightly ajar, and cook about 25 to 30 minutes, stirring occasionally, until lentils and potatoes turn tender.

Step 4: Adjust texture and seasoning

Check the texture of the soup. If you want a thicker consistency, use an immersion blender and pulse a few times right in the pot, or mash some potatoes and lentils against the side with a spoon.

If the soup looks too thick, add a bit more broth or water until it reaches your preferred consistency. Stir in chopped spinach or kale at this point, if you use it, and cook 3 to 5 minutes until the greens wilt and soften.

Step 5: Finish with acid and richness

Turn off the heat and remove the bay leaf. Stir in lemon juice, starting with half the lemon and adding more to taste.

If you want a creamier Easy Lentil Potato Soup Recipe, swirl in coconut milk or a splash of cream. Taste again and adjust salt and pepper until the flavor tastes balanced and bright.

Step 6: Serve

Ladle the soup into bowls while hot. Top with a spoonful of Greek yogurt or non-dairy yogurt, a sprinkle of fresh herbs, and a pinch of red pepper flakes if you like a little kick.

Serve with crusty bread, warm flatbread, or a simple green salad for a full meal. Enjoy leftovers for lunch, since this soup thickens and deepens in flavor overnight.
