Step-by-Step Instructions

1. Sauté the Onion

Begin by heating a generous drizzle of olive oil or avocado oil in a large soup pot over medium heat.

Add the finely chopped onion and cook for about 5–7 minutes, stirring occasionally, until the onion becomes soft and lightly golden. This step helps build the flavor base of the soup.

2. Add the Vegetables and Spices

Once the onion is softened, add the chopped carrot and minced garlic to the pot.

Next, sprinkle in the paprika powder, turmeric powder, cumin, salt, and black pepper. Stir everything together and allow the spices to cook for about 2–3 minutes. This process toasts the spices and releases their aromas, enhancing the flavor of the soup.

3. Add the Potato and Lentils

Add the chopped potato and the rinsed red lentils to the pot. Stir them into the vegetable and spice mixture so they are evenly coated with the flavors.

The potato helps give the soup extra body and creaminess once blended.

4. Pour in the Stock

Carefully pour the vegetable or chicken stock into the pot and stir well to combine.

Increase the heat slightly and bring the mixture to a gentle boil.

5. Simmer the Soup

Once the soup begins to boil, reduce the heat to low and allow it to simmer covered for about 30–35 minutes.

During this time, the lentils will soften and break down naturally, while the vegetables become tender. Stir occasionally to ensure nothing sticks to the bottom of the pot.

6. Blend Until Smooth

Once the lentils are fully cooked and soft, remove the pot from the heat.

Using an immersion blender, carefully blend the soup until it becomes smooth and creamy. If you prefer a slightly textured soup, you can blend it only partially.

7. Add the Lemon Juice

Stir in the fresh juice of one lemon. This step brightens the soup and balances the warm spices beautifully.

Taste the soup and adjust the seasoning with additional salt or pepper if needed.

8. Serve and Garnish

Ladle the warm red lentil soup into serving bowls. Finish each bowl with a sprinkle of freshly chopped parsley, a drizzle of extra virgin olive oil, and a pinch of chili flakes for a gentle kick of heat.

The parsley adds freshness, the olive oil brings richness, and the chili flakes give the soup a subtle spicy contrast that balances the creamy texture beautifully.

Serve the soup immediately while hot and enjoy it with crusty bread, warm flatbread, or a simple side salad for a comforting and satisfying meal.

Expert Tips

Always rinse the lentils.
Rinsing removes dust and excess starch, helping the soup maintain a cleaner flavor.

Don’t skip sautéing the onions.
Properly cooking the onions adds depth and sweetness to the soup.

Toast the spices briefly.
Cooking spices in oil for a few minutes intensifies their flavor.

Blend carefully.
If using an immersion blender, allow the soup to cool slightly before blending to prevent splattering.

Adjust the texture.
If the soup becomes too thick, add a little extra stock or water until you reach your preferred consistency.
