Iraqi Red Soup Recipe with Lentils, Rice, and Tomato

Iraqi red soup is a warming, tomato-tinted lentil soup, often made with red lentils and familiar pantry vegetables; household versions vary in their use of rice, spices, and texture. This one-pot version pairs lentils with a little rice, carrot, and potato, then finishes with lemon for a filling soup that is easy to adapt and serve as a meal.

Ingredients

2 tablespoons olive oil (30 ml)
1 medium yellow onion, finely diced (about 150 g)
2 medium carrots, peeled and diced (about 200 g)
1 medium potato, peeled and diced (about 200 g)
3 garlic cloves, finely chopped (about 9 g)
1½ cups dried red lentils, rinsed and drained (285 g)
⅓ cup long-grain white rice, rinsed and drained (65 g)
2 tablespoons tomato paste (about 32 g)
1 teaspoon ground cumin (2 g)
½ teaspoon ground turmeric (about 1.5 g)
½ teaspoon ground coriander (about 1 g)
¼ teaspoon ground black pepper (about 0.5 g)
7 cups water or low-sodium vegetable broth (1.65 L)
1½ teaspoons kosher salt (about 9 g), plus more to taste; use less if your broth is salty
2 tablespoons fresh lemon juice (30 ml)
¼ cup chopped fresh parsley (about 15 g)
Lemon wedges, for serving (about 1 lemon)

Instructions

Prepare the lentils and rice. Rinse the red lentils in a fine-mesh sieve until the water runs mostly clear, picking out any small debris. Rinse and drain the rice separately. Red lentils do not need soaking; rinsing removes surface starch and dust and helps the soup cook evenly. Dice the onion, carrots, and potato into small pieces so they soften at roughly the same rate.
Soften the vegetables. Warm the olive oil in a large heavy pot or Dutch oven over medium heat. Add the onion, carrots, and potato and cook for 8 minutes, stirring every minute or two. The onion should turn translucent and the vegetables should begin to soften, but they do not need to brown. If the bottom of the pot starts to look dry, lower the heat slightly and stir in a tablespoon of water.
Toast the aromatics and tomato paste. Add the garlic, cumin, turmeric, coriander, and black pepper. Stir for 1 minute, just until fragrant; avoid letting the garlic darken. Add the tomato paste and cook for another minute, stirring so it coats the vegetables. Briefly cooking the paste deepens its flavor and gives the soup its red color without making it taste raw or sharp.
Add the lentils, rice, and liquid. Tip in the rinsed lentils and rice, then pour in the water or broth. Add the salt and stir well, scraping the bottom of the pot to loosen any tomato paste. Bring the liquid to a boil over medium-high heat, which should take about 4 minutes. Once it boils, reduce the heat to maintain a steady, gentle simmer and partially cover the pot.
Simmer until tender. Cook for 25 minutes, stirring every 5 to 7 minutes so rice and lentils do not settle and catch on the bottom. The soup is ready for the next step when the lentils have broken down, the rice is tender, and the carrot and potato pieces can be pierced easily with a fork. If the simmer is vigorous, lower the heat; a rolling boil can make the lentils foam and may cause sticking.
Set the texture and season. For a thick, mostly smooth soup with some texture, use an immersion blender for a few short pulses, keeping the blade below the surface to prevent splashes. Alternatively, mash a few spoonfuls of lentils against the side of the pot with a wooden spoon. Stir in the lemon juice and parsley, taste, and add salt or another squeeze of lemon as needed. This final blending and seasoning takes about 2 minutes; the total cooking time is about 40 minutes.
Serve hot. Ladle the soup into bowls and offer lemon wedges at the table. If it has thickened while standing, stir in warm water a little at a time until it is easy to spoon. Taste once more after thinning, since extra liquid can soften the seasoning.

Tips

Use the right lentils. Red lentils, which are often sold split and hulled, soften quickly and give the soup its characteristic thick body. Brown or green lentils stay much firmer and need more time, so they will not produce the same texture on this schedule. If those are all you have, cook them separately until tender and expect a more brothy, clearly textured soup.
Choose water or broth deliberately. Water lets the cumin, tomato, and lemon stand out cleanly. Low-sodium vegetable broth gives a fuller savory flavor; regular broth can make the soup too salty, so start with less salt and adjust after simmering. If you cannot find ground coriander, leave it out rather than replacing it with a large amount of a different spice. The soup will still taste balanced, just a little less citrusy and warm.
Control thickness with liquid, not extra cooking. Lentils and rice continue absorbing broth as the soup cools, so a pot that looks loose at first can become quite thick. Add hot water or broth a little at a time to loosen it. If it is thinner than you like, simmer uncovered for a few minutes, stirring often so the lentils do not stick.
Keep the lemon for the end. Adding lemon after the lentils and rice are tender gives a fresh, clear finish and makes it easier to balance the acidity to taste. If the soup tastes flat, first try a small pinch of salt and a squeeze of lemon rather than adding more tomato paste or spices.

Serving Suggestions

Serve Iraqi red soup as a first course or make it the center of a simple lunch or supper. Warm flatbread, pita, or crusty bread is useful for scooping up the thick lentils, while a crisp salad of cucumber, tomato, and herbs adds freshness. For a more substantial table, offer rice on the side, pickled vegetables, olives, or a plate of sliced raw vegetables. Keep lemon wedges nearby so each person can brighten their own bowl.

For a gentle finishing touch, drizzle a little olive oil over each serving and scatter on extra parsley. A small dish of chili flakes or mild pickled peppers lets people add heat without changing the pot for everyone. If serving guests, keep the soup warm over very low heat and stir it regularly; add a splash of hot water if it becomes too dense while waiting.

Variations

Iraqi red soup is not one fixed formula, and the balance of lentils, rice, vegetables, and seasoning differs between households. This recipe is a meat-free version built around red lentils and tomato paste. For a more tomato-forward flavor, stir in one finely chopped ripe tomato with the tomato paste, then add a little extra water if the soup becomes thicker than expected. The tomato will bring a fresher, slightly tangier taste than paste alone.

For a gluten-free bowl, check that the broth and tomato paste are labeled gluten-free; the listed ingredients contain no wheat. For a vegan version, use water or vegetable broth as written. To make the soup without rice, omit it and reduce the liquid by about ½ cup (120 ml) to begin with; lentils alone still thicken the broth, and you can add more liquid while simmering if needed. For a heartier, more textured result, add a drained 15-ounce can of chickpeas (about 425 g) during the last 10 minutes of simmering. They will warm through without disintegrating.

You can also adjust the spice profile modestly. A pinch of paprika can deepen the red color, while a little extra cumin makes the soup earthier. Add spices in small increments and taste after they have simmered; large additions can cover the lemon and lentil flavor. If you enjoy heat, serve chili flakes at the table instead of adding them to the whole pot.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking in shallow, covered containers. The soup keeps for 3 to 4 days in the refrigerator. It thickens considerably as the rice and lentils absorb liquid, which is normal; stir in water or broth when reheating until you reach the consistency you prefer. Reheat on the stovetop over medium-low heat, stirring frequently, or microwave in a covered microwave-safe bowl in short intervals, stirring between intervals. Reheat leftovers to 165°F (74°C), checking the center with a food thermometer.

For longer storage, freeze the cooled soup in airtight freezer-safe containers for up to 3 months for best quality, leaving a little space at the top for expansion. Thaw overnight in the refrigerator or warm it from frozen in a covered pot over low heat with a splash of water. Rice can become softer after freezing and reheating, but the flavor remains pleasant. Do not leave the soup at room temperature for extended storage; refrigerate or freeze it instead.

Frequently Asked Questions

Is Iraqi red soup the same as Iraqi lentil soup?

The names can overlap. Red soup often describes a tomato-colored lentil soup, and Iraqi households make versions with different combinations of lentils, rice, vegetables, and seasonings. This recipe is an Iraqi-style red lentil soup; it is not meant to represent every regional or family preparation.

Do I need to soak red lentils before cooking?

No. Rinse them well and add them directly to the pot. Split red lentils cook quickly and soften during the 25-minute simmer. Soaking is unnecessary here and can make the lentils break down even faster, which may leave the finished soup thicker than intended.

Can I make this soup without a blender?

Yes. Red lentils naturally soften and thicken the broth, so blending is optional. Leave the soup as it is for a rustic texture, or mash a few spoonfuls against the pot with the back of a spoon. Avoid transferring very hot soup to a countertop blender unless its instructions specifically allow hot liquids and you can vent it safely.

Why did my soup become so thick?

Rice and lentils absorb liquid during cooking and continue to do so as the soup cools. Stir in warm water or broth until it loosens, then taste and adjust the salt and lemon. If you plan to serve it later, keep it slightly thinner than your preferred final texture because it will continue to thicken while standing.

Can I use brown or green lentils instead?

You can, but the result will be different. Brown and green lentils hold their shape more and take longer to become tender, so the soup will be less creamy and may need extra simmering time and liquid. For the texture and timing described here, dried split red lentils are the best choice.

What can I use instead of tomato paste?

If tomato paste is unavailable, use about ½ cup (120 ml) canned crushed tomatoes and reduce the water or broth by roughly ¼ cup (60 ml) to start. The soup will taste fresher and less concentrated, and it may need a few extra minutes uncovered to thicken. Taste near the end and add lemon or salt only as needed.
