Moroccan Red Lentil Quinoa Soup with Lemon and Herbs

Moroccan-style red lentil quinoa soup is a gently spiced, tomato-rich soup with tender vegetables, soft red lentils, and fluffy quinoa, finished with lemon and fresh herbs. The combination makes a satisfying one-pot meal; spice blends and garnishes vary, and this is a flexible home-style version rather than a claim to one definitive regional recipe.

Ingredients

2 tablespoons (30 ml) olive oil
1 medium yellow onion, diced, about 1 cup (150 g)
2 medium carrots, diced, about 1 cup (200 g)
2 celery ribs, diced, about ½ cup (80 g)
4 garlic cloves, finely chopped, about 12 g
2 tablespoons (30 g) tomato paste
2 teaspoons (4 g) ground cumin
1½ teaspoons (3 g) ground coriander
1 teaspoon (2 g) sweet paprika
1 teaspoon (2 g) ground ginger
½ teaspoon (1.5 g) ground turmeric
¼ teaspoon ground cinnamon, about 0.5 g
⅛ teaspoon cayenne pepper, about 0.3 g, or more to taste
1 cup (190 g) dried red lentils, picked over and rinsed
½ cup (85 g) white quinoa, rinsed well and drained
1 can (14½ ounces/411 g) diced tomatoes, with their juices
6 cups (1.42 L) vegetable broth, preferably low-sodium
1 bay leaf
1¼ teaspoons (7 g) fine salt, or to taste
½ teaspoon (1 g) freshly ground black pepper
2 tablespoons (30 ml) fresh lemon juice, plus more to taste
½ cup (15 g) chopped fresh cilantro, parsley, or a mix
Up to 1 cup (240 ml) hot water, as needed to loosen the soup

Instructions

Rinse and prepare the grains and lentils. Rinse the quinoa in a fine-mesh strainer under cool running water, rubbing the grains gently with your fingers, then drain. Rinse the red lentils separately and remove any small stones or debris. Red lentils do not need soaking. Dice the onion, carrots, and celery, and chop the garlic before you start cooking so the aromatics are ready to go.
Soften the vegetables. Warm the olive oil in a large, heavy-bottomed soup pot over medium heat. Add the onion, carrots, and celery and cook for 8 minutes, stirring every minute or two. The onion should look translucent and the carrots should begin to soften, but the vegetables do not need to brown. If the pot seems dry or the onion starts sticking, lower the heat and stir in a tablespoon of water.
Bloom the spices. Stir in the garlic, tomato paste, cumin, coriander, paprika, ginger, turmeric, cinnamon, and cayenne. Cook for 1 minute, stirring constantly, until the garlic smells fragrant and the tomato paste darkens slightly. Keep the mixture moving; ground spices can scorch quickly on the bottom of a hot pot.
Add the broth and lentils. Pour in the diced tomatoes and vegetable broth. Add the rinsed red lentils, bay leaf, salt, and black pepper, then stir well and scrape up any flavorful bits from the bottom of the pot. Bring the mixture to a gentle simmer over medium-high heat; allow about 3 minutes for it to come up to temperature, adjusting the heat if it begins to boil hard.
Simmer the lentils. Lower the heat, cover the pot with the lid slightly ajar, and simmer for 12 minutes. Stir once or twice, checking that the soup is bubbling gently rather than vigorously. This head start gives the lentils time to soften before the quinoa goes in. If the pot is simmering too rapidly, reduce the heat to prevent the lentils from sticking.
Cook the quinoa. Stir in the drained quinoa, cover the pot slightly ajar again, and simmer for 16 minutes. Stir once halfway through and check the bottom of the pot. The quinoa is ready when its grains look translucent around the edges and show their little curled tails; the lentils should be very soft and beginning to break down. If either needs another minute or two, continue simmering and check again.
Finish and adjust. Remove the bay leaf. Stir in the lemon juice and chopped cilantro or parsley. Taste the soup and add more salt, pepper, or lemon as needed. For a thinner consistency, add hot water a little at a time; the lentils and quinoa continue absorbing liquid as the soup stands. Ladle into bowls and serve hot.

Tips

Rinse quinoa thoroughly. Quinoa can have a naturally bitter coating called saponin. A fine-mesh strainer is useful because the dry seeds are small; rinse until the water running through is clear. Packaged quinoa labeled pre-rinsed still benefits from a quick rinse if you are sensitive to bitterness.
Keep the simmer gentle. A rolling boil can break down the lentils unevenly and make the bottom of the pot catch before the quinoa is tender. Stir occasionally, especially after adding quinoa, and add a splash of water if the soup thickens too quickly.
Adjust for the broth you use. Salt levels vary widely between vegetable broths. Start with the listed amount if your broth is low-sodium, or begin with ½ teaspoon if it is salted and season again at the end. Lemon brightens the finished soup, but add it gradually so it does not overpower the spices.
Know your spice substitute. Ras el hanout is a Moroccan spice blend that can be used in place of the cumin, coriander, paprika, ginger, turmeric, and cinnamon: start with 1 tablespoon (about 7 g), then taste. Blends differ in heat and composition, so the flavor will be less predictable. If you cannot find it, the listed individual spices are a straightforward pantry alternative.

Serving Suggestions

Serve the soup in warm bowls with another squeeze of lemon and a generous scattering of cilantro, parsley, or both. A spoonful of plain yogurt adds a cool, creamy contrast; use a plant-based yogurt if you want to keep the topping dairy-free. For crunch, offer toasted pumpkin seeds, sliced almonds, or crisp pieces of flatbread at the table, rather than stirring them into the pot where they will soften.

For a more filling meal, pair the soup with warm pita, Moroccan-style flatbread, or crusty bread for dipping. A simple salad of cucumber, tomato, and greens works well alongside it, particularly if dressed lightly with lemon and olive oil. The soup is substantial enough to serve on its own for lunch, but bread and a fresh side make an easy dinner. Put extra lemon wedges and herbs on the table so each person can season their bowl.

Variations

Add greens: Stir in 2 packed cups (60 g) of baby spinach during the final 2 minutes of cooking, or add chopped kale with the quinoa and allow it to simmer until tender. Kale takes longer than spinach, so check that it has softened before serving.

Change the heat: Leave out the cayenne for a mild soup, or add a little more for a warmer finish. Harissa, a North African chile paste, is another option: stir in 1 to 2 teaspoons with the tomato paste and spices. If it is unavailable, cayenne and paprika give some heat and color, though they will not reproduce harissa’s distinct chile-and-spice flavor.

Use a different grain: Brown or green lentils hold their shape more than red lentils and need a longer cooking time, so they are not a direct swap in this schedule. For a practical change, omit the quinoa and add ½ cup (90 g) of rinsed brown rice with the lentils; simmer until the rice is tender, adding broth if needed. The soup will take longer, and the texture will be less creamy.

Make it richer or smokier: Replace the sweet paprika with smoked paprika for a subtle smoky note, or stir a teaspoon of olive oil into each bowl just before serving. Keep the lemon in the recipe either way; its acidity helps balance the soup’s earthy spices and soft lentils.

Storage and Reheating

Let leftovers cool briefly, then refrigerate them within 2 hours of cooking in shallow, airtight containers. The soup keeps for 3 to 4 days in the refrigerator. It thickens as the lentils and quinoa absorb broth, so expect leftovers to be more porridge-like than freshly cooked soup. Add a splash of water or broth when reheating, then adjust the lemon and salt after the texture loosens.

Reheat on the stovetop over medium-low heat, stirring often, until the soup is steaming throughout and reaches 165°F (74°C); check with a food thermometer. For microwave reheating, use a microwave-safe bowl, cover loosely, stir partway through, and check the temperature in more than one spot. Freeze portions in airtight, freezer-safe containers for up to 2 to 3 months for best quality. Leave room for expansion, thaw overnight in the refrigerator, and reheat to 165°F (74°C). The quinoa may soften after freezing, but the soup remains suitable for serving.

Frequently Asked Questions

Do I need to soak the red lentils?

No. Rinsing is enough for this recipe, and soaking would make the lentils cook more quickly and could cause them to break down before the quinoa is tender. Pick through them as you rinse, then drain well so you do not add extra water to the measured broth.

Can I use cooked quinoa instead of dry quinoa?

Yes. Cook the lentils for the full 12-minute head start, then simmer until they are nearly tender. Stir in about 1½ cups (280 g) cooked quinoa during the final 3 to 5 minutes, just long enough to heat it through. Since cooked quinoa adds less starch and absorbs less liquid during cooking, the soup may be a little thinner; simmer briefly uncovered or add a small amount of broth as needed.

Is this soup gluten-free?

The ingredients listed are naturally gluten-free, but check the package labels on your vegetable broth, spice blends, and any bread or toppings served with it. Cross-contact can occur during processing, so use products labeled gluten-free when that matters for your meal.

Why is my soup thicker the next day?

Red lentils soften and release starch, while quinoa continues absorbing liquid as the soup cools and sits. Stir in water or broth while reheating, starting with ¼ cup (60 ml) per portion and adding more until you like the consistency. Taste again afterward because dilution can also reduce the salt and lemon flavor.

Can I make the soup ahead?

Yes. Cook it completely, cool it promptly, and refrigerate it in airtight containers within 2 hours. It will thicken overnight, so plan to loosen it with broth or water when reheating. For a fresher grain texture, you can cook the soup through the lentil stage ahead, refrigerate it, then bring it to a simmer and add freshly rinsed quinoa when you are ready to finish cooking.
