Ingredients You’ll Need

A pot of this soup bubbling on the stove is the kind of simple luxury that turns everyday cooking into something special.

One of the things I love about this recipe is that it uses simple pantry ingredients. You probably already have most of them in your kitchen.

Base Ingredients:

1 cup dried lentils
1 tablespoon olive oil
1 medium onion, chopped
2 cloves garlic, minced
2 medium carrots, diced
1 celery stalk, chopped
4 cups vegetable broth
1 cup diced tomatoes
1 teaspoon cumin
1/2 teaspoon turmeric
1/2 teaspoon paprika
1/2 teaspoon salt
1/2 teaspoon black pepper

Optional Add-ins:

1 tablespoon lemon juice
1 teaspoon chili flakes
2 tablespoons fresh parsley, chopped
1/2 teaspoon smoked paprika
1 cup spinach or kale

Step-by-Step Instructions

Step 1: Prepare the Base Aromatics

Heat olive oil in a large pot over medium heat. Add chopped onion, carrots, and celery, sautéing until softened and fragrant. Stir in garlic and cook briefly until aromatic. This foundational step builds depth and flavor, ensuring your soup starts with a rich and well-balanced base.

Step 2: Add Lentils and Spices

Rinse lentils thoroughly and add them to the pot. Sprinkle in cumin, turmeric, paprika, salt, and black pepper. Stir everything together to coat the lentils with spices. This step allows the flavors to bloom, creating a deeper, more complex taste throughout the soup.

Step 3: Simmer the Soup

Pour in vegetable broth and diced tomatoes, then bring the mixture to a gentle boil. Reduce heat and let it simmer for 25–30 minutes until lentils are tender. Stir occasionally to prevent sticking. This slow cooking process allows the lentils to absorb flavors while softening perfectly.

Step 4: Finish and Adjust

Once lentils are fully cooked, taste and adjust seasoning if needed. Add lemon juice, greens, or herbs for brightness and freshness. Let the soup rest for a few minutes before serving to allow flavors to settle and intensify for a perfectly balanced finish.
