When it rains, my son always wonders why we have soup. I didn’t have a good answer, but this Easy Lentil Soup is a staple in our house. With just 7 ingredients, it’s a simple way to fill up when the weather’s gloomy and keeps everyone satisfied, even on the busiest days.


Using dried lentils and simmering them in water lets them absorb flavors while breaking down slightly. This creates a thick, hearty texture that’s satisfying and makes the soup more filling, thanks to the lentils’ starches helping to bind everything together.

Ingredients in Easy Lentil Soup

This soup leans on a few key ingredients to deliver maximum flavor with minimal fuss. Each one plays a vital role in creating that comforting, hearty profile we all love.

  • Olive Oil: Adds richness and helps enhance the veggies’ flavors.
  • Celery: Brings a fresh, crunchy element and builds the flavor base.
  • Carrots: Adds natural sweetness and color, balancing the savory notes.
  • Onion: A must for depth; it sweetens as it cooks, making the soup more satisfying.
  • Garlic: Packs a punch of flavor; use fresh for the best results.
  • Dried Green or Brown Lentils: The star here! They absorb flavors and create a thick texture as they cook.
  • Ground Cumin: Infuses warmth, giving the soup a comforting, earthy depth.
  • Kosher Salt: Essential for enhancing all the flavors; adjust to your taste.
  • Water: Provides the necessary liquid for simmering and helps meld the flavors together.

How to Make Easy Lentil Soup

This Easy Lentil Soup comes together in about 50 minutes, including 10 minutes of prep and 40 minutes of cooking. It’s a straightforward process that’ll fill your kitchen with cozy aromas, making it perfect for a rainy day.

  1. Heat Oil: In a large pot or Dutch oven, heat olive oil over medium-high heat. This should take about 1-2 minutes. Once it’s shimmering, you’ll know it’s ready for the next step.

  2. Cook Veggies: Add finely chopped celery stalks, peeled and finely chopped carrots, and finely diced onion. Cook for 5-6 minutes, stirring occasionally, until the veggies are tender and the onion is translucent.

  3. Add Ingredients: Pour in water, and add dried lentils, ground cumin, and kosher salt. Stir everything together and bring the mixture to a simmer. You’ll see tiny bubbles forming on the surface after a few minutes.

  4. Simmer Lentils: Let the soup simmer for 30 minutes, stirring occasionally. The lentils should be tender but not mushy. If they aren’t quite there, keep cooking for a few more minutes. This is key for that hearty texture!

  5. Adjust Seasoning: Taste the soup and add kosher salt if needed.

Serve it up hot. Enjoy!

Switch It Up: Easy Variations

I love how versatile this Easy Lentil Soup can be! Whether you want to tweak the flavors or switch up the texture, here are some fun ways to make it your own.

  • Curry Powder Addition: Add ½ tablespoon of curry powder for a warm, spicy twist that adds depth to the soup.
  • Coconut Milk Variation: Stir in ¾ cup of full-fat coconut milk for a creamier texture and a hint of sweetness.
  • Potato Addition: Toss in a small diced potato after sautéing the veggies for extra heartiness and a thicker consistency.
  • Sweet Potato Variation: For a different flavor, try making a Sweet Potato Lentil Soup.

These tweaks let you personalize the soup while keeping it easy!

Keeping the Soup Fresh

You can store leftovers of this Easy Lentil Soup in the fridge for up to a week. Make sure to let it cool before sealing it in an airtight container. If you want to keep it longer, it freezes well for up to three months. Just remember to leave a little space in the container since it’ll expand as it freezes.

When reheating, I recommend using the stovetop on low heat. Add a splash of water to loosen it up and stir often to prevent it from sticking or burning. This way, you’ll keep that hearty texture and flavor intact without any fuss.
