Why You’ll Love This Recipe
This recipe is wonderfully easy to make, even on a busy day. With only a short prep time and one pot, it delivers deep flavor without a complicated method. Red lentils cook quickly and naturally thicken the soup, giving it a creamy texture without needing heavy ingredients. The tomatoes bring brightness, the cumin adds earthy warmth, and the basil rounds everything out with a gentle herbal note. It is also easy to adjust, so you can make it milder, spicier, smoother, or chunkier depending on your taste.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1 tablespoon olive oil
1 medium onion, finely chopped
1 chile pepper, chopped
1 cup red lentils, rinsed
1 can (14.5 ounces) peeled and diced tomatoes
1 cup water
1/2 teaspoon ground cumin
1 teaspoon dried basil
Salt, to taste
Black pepper, to taste
1/4 cup sour cream, for topping (optional)
2 sprigs fresh basil leaves, for garnish (optional)
Directions
Heat the olive oil in a large saucepan or Dutch oven over medium heat. Add the finely chopped onion and cook for a few minutes, stirring occasionally, until it begins to soften and lightly brown.
Add the chopped chile pepper, red lentils, diced tomatoes with their juices, water, ground cumin, and dried basil. Stir well so the lentils are evenly distributed through the liquid.
Bring the mixture to a gentle boil. Once it starts bubbling, reduce the heat to medium-low and let it simmer for about 20 minutes. Stir once or twice during cooking to make sure the lentils do not stick to the bottom of the pot.
When the lentils are fully tender, remove the soup from the heat. Use a stick blender to puree the soup until smooth. If you prefer, you can blend it in batches using a countertop blender, taking care with the hot liquid.
Season with salt and black pepper to taste. Ladle into bowls and finish with a spoonful of sour cream and fresh basil if desired. Serve hot with thick slices of crusty bread for a filling meal.

Variations
For a creamier finish, stir in a little extra sour cream or a splash of cream after blending. To make the soup more filling, add diced carrots at the beginning with the onion. For a deeper flavor, cook a little garlic with the onion before adding the other ingredients. You can also use vegetable broth instead of water for a richer base. If you enjoy more heat, add an extra chile pepper or a pinch of chili flakes. For a chunkier version, blend only half the soup and leave the rest as is.
Storage/Reheating
Let the soup cool completely before storing. Transfer it to an airtight container and keep it in the refrigerator for up to 4 days. For longer storage, freeze it in individual portions for up to 3 months. Thaw overnight in the refrigerator before reheating.
To reheat, warm the soup gently in a saucepan over medium-low heat, stirring occasionally until heated through. You can also microwave it in short intervals, stirring between each one. If the soup thickens too much after chilling, add a splash of water or broth to loosen it.
FAQs
Can I use green or brown lentils instead of red lentils?
You can, but the texture and cooking time will change. Red lentils break down quickly and create a smooth soup, while green or brown lentils stay firmer and usually need longer to cook.
Is this soup very spicy?
It has a gentle kick from the chile pepper, but it is not overwhelmingly hot. You can reduce the heat by using less chile or removing the seeds before chopping.
Can I make this soup without blending it?
Yes. The soup will be more rustic and textured if left unblended. It will still taste delicious.
What can I use instead of sour cream?
Plain yogurt works well as a topping. You can also leave it out completely if you want a lighter finish.
Can I make this soup dairy-free?
Yes. Simply skip the sour cream or use a dairy-free alternative for serving.
What should I serve with this soup?
Crusty bread, toast, or a simple salad pair very well with it. It also works nicely as a starter before a larger meal.
Can I use fresh tomatoes instead of canned?
Yes, but canned tomatoes usually give a deeper and more consistent flavor in this type of soup. If using fresh tomatoes, peel and chop them first.
Why is my soup too thick?
Lentils absorb liquid as they cook and continue to thicken after blending. Add a little more water or broth until the soup reaches your preferred consistency.
Can I prepare this soup ahead of time?
Yes. It is a great make-ahead recipe because the flavors continue to develop as it rests.
How do I make it more flavorful?
Using broth instead of water, adding garlic, or finishing with extra fresh basil can all boost the flavor. A small squeeze of lemon at the end can also brighten the soup.
