Ingredients You Need

Lentils

1 cup brown or green lentils, rinsed
- Brown lentils hold shape nicely and cook in about 25 to 30 minutes.
- Green lentils stay a bit firmer and give a slightly nuttier flavor.
- Avoid red lentils here, since they break down too much and turn the soup into more of a puree.

Potatoes

3 medium Yukon Gold potatoes, peeled if you like, cut into 1 inch cubes
- Yukon Golds give a creamy texture without falling apart.
- Use russet potatoes if that is what you have, but cut them a bit larger so they do not disintegrate.
- Leave the peel on if you want extra fiber and a more rustic feel.

Vegetables and aromatics

1 medium yellow onion, diced
2 medium carrots, diced
2 celery stalks, diced
3 to 4 garlic cloves, minced
1 tablespoon tomato paste
1 can (14.5 ounces) diced tomatoes, with juices
- Fire roasted tomatoes add a deeper flavor if you can find them.
- Use crushed tomatoes if you prefer a smoother broth.

Broth and liquid

6 cups vegetable broth or chicken broth
- Use low sodium broth so you can season to taste.
- In a pinch, use water plus 2 teaspoons better quality bouillon paste.
1 cup water, as needed to thin the soup near the end

Oil and fat

2 tablespoons olive oil
- Use avocado oil or canola oil if that is what you keep in your pantry.

Herbs and spices

1 ½ teaspoons kosher salt, plus more to taste
½ teaspoon black pepper
1 teaspoon smoked paprika or sweet paprika
1 teaspoon ground cumin
1 teaspoon dried thyme or Italian seasoning
1 bay leaf
Pinch of red pepper flakes, optional, for a little heat

Finishers and toppings

Juice of ½ lemon, plus extra wedges for serving
2 tablespoons chopped fresh parsley or cilantro
Plain Greek yogurt or plain unsweetened yogurt for topping, optional
Grated Parmesan or a dairy free grated cheese, optional

Pantry shortcuts and notes

Use frozen diced onions and carrots if chopping sounds annoying after a long day.
Use pre minced garlic from a jar in a pinch, though fresh garlic gives better flavor.
Use canned potatoes if you feel desperate, but add them near the end since they already feel tender.

Equipment list

Large heavy bottomed pot or Dutch oven, at least 5 quart size
Cutting board and sharp knife
Wooden spoon or heat safe spatula
Measuring cups and spoons
Ladle for serving
Blender or immersion blender, optional, if you want a creamier texture

Tips & Mistakes

Sauté the veggies until they look slightly golden, not just soft, to build deeper flavor.
Rinse lentils under cold water until it runs clear to remove dust and extra starch.
Cut potatoes into even cubes so they cook at the same rate and do not turn mushy.
Keep the heat at a gentle simmer, not a hard boil, so lentils cook evenly and stay tender.
Taste the broth before adding more salt, since different broths carry different salt levels.
Add acidic ingredients like lemon juice at the end so they stay bright and do not dull during cooking.
Stir the soup every 5 to 10 minutes so lentils do not stick to the bottom of the pot.
Add extra water or broth if the soup thickens more than you like, especially when you reheat leftovers.
Do not add dairy directly to the big pot if you plan to freeze leftovers, since dairy can separate; add yogurt or cheese to each bowl instead.
Use a partial blend of the soup if you want it thicker, but avoid blending the entire pot or it can turn gluey.

How to Make Easy Lentil Potato Soup Recipe

Step 1: Prep ingredients

Chop onion, carrots, and celery into small, even pieces so they cook at the same speed. Peel and cube the potatoes into 1 inch chunks. Rinse the lentils in a fine mesh strainer until the water runs mostly clear, then set them aside.

Step 2: Sauté the aromatics

Heat olive oil in a large pot over medium heat. Add onion, carrots, and celery, then cook 6 to 8 minutes until the veggies soften and start to turn golden around the edges. Stir in garlic and cook about 30 seconds until it smells fragrant, not burnt.

Step 3: Build the flavor base

Add tomato paste to the pot and stir it into the veggies. Cook 1 to 2 minutes so the tomato paste darkens slightly and loses its raw taste. Sprinkle in smoked paprika, cumin, thyme, red pepper flakes if you use them, plus salt and pepper, then stir to coat everything.

Step 4: Add lentils, potatoes, and liquids

Add the rinsed lentils and potato cubes to the pot. Pour in the diced tomatoes with their juices and the broth. Toss in the bay leaf, then stir well so nothing sticks to the bottom.

Step 5: Simmer until tender

Bring the pot to a gentle boil over medium high heat, then lower the heat to maintain a steady simmer. Cover the pot partially, leaving a small gap for steam to escape. Cook 25 to 30 minutes, stirring every 5 to 10 minutes, until lentils feel tender and potatoes pierce easily with a fork.

Step 6: Adjust thickness and texture

Check the thickness of the soup. Add up to 1 cup of water or extra broth if it feels too thick for your taste. If you want a creamier texture, scoop 1 to 2 cups of the soup into a blender, blend until smooth, then pour it back into the pot and stir.

Step 7: Finish with brightness

Turn off the heat and remove the bay leaf. Stir in lemon juice and chopped parsley or cilantro. Taste and adjust with more salt, pepper, or lemon juice until the flavors pop.

Step 8: Serve

Ladle the Easy Lentil Potato Soup Recipe into bowls. Add a dollop of yogurt or a sprinkle of grated cheese if you like. Top with extra herbs and a squeeze of lemon for a fresh finish.

Variations I've Tried

I swap half the potatoes for sweet potatoes when I crave a slightly sweet, earthy version. I add a handful of chopped spinach or kale in the last 5 minutes of cooking when I want more greens. I stir in a spoonful of coconut milk at the end for a creamier, lightly sweet twist that still stays dairy free.

I sometimes add a small diced bell pepper with the carrots and celery for extra color and sweetness. I toss in a teaspoon of curry powder and a pinch of turmeric for a cozy curry lentil potato soup that tastes great with cilantro and lime. I use red lentils once in a while and reduce the cooking time to about 20 minutes for a softer, stew like texture.
