Ingredients

• 2 tablespoons olive oil (or neutral oil)
• 1 large yellow onion, finely diced
• 2 medium carrots, peeled and diced
• 3 cloves garlic, minced
• 1 teaspoon ground cumin
• ½ teaspoon smoked paprika (optional, for depth)
• 2 tablespoons tomato paste
• 1 ½ cups (about 300g) dried red lentils, rinsed well
• 6 cups (1.5 liters) vegetable broth (or water)
• 1 teaspoon salt (or to taste)
• Freshly ground black pepper

Instructions

1. Gather your ingredients and get cozy in the kitchen — Place a large pot or Dutch oven over medium heat. This one-pot wonder is about to fill your home with the most inviting aromas.
2. Warm the oil and start building flavor — Add the olive oil and let it shimmer gently. Toss in the diced onion and carrots, stirring occasionally for 5-7 minutes until they soften and the onion turns translucent and sweet.
3. Add garlic and spices for magic — Stir in the minced garlic, ground cumin, and smoked paprika. Cook for just 1 minute until everything smells wonderfully fragrant—your kitchen will smell amazing right now!
4. Stir in tomato paste — Add the tomato paste and cook for another minute, stirring well so it coats the vegetables and deepens in color. This step creates rich, savory backbone.
5. Rinse and add the red lentils — Give your rinsed red lentils a quick drain, then pour them into the pot. Stir everything together so the lentils get nicely coated with all those delicious flavors.
6. Pour in the broth and season — Add the vegetable broth, salt, and a few grinds of black pepper. Give it a good stir, scraping up any bits from the bottom of the pot for extra taste.
7. Bring to a gentle boil — Increase the heat to bring the soup to a lively simmer, then reduce to medium-low. Cover partially with a lid and let it bubble away happily.
8. Simmer until creamy and tender — Cook for 20-25 minutes, stirring occasionally. The red lentils will soften and naturally thicken the soup into a beautiful, hearty consistency.
9. Brighten with lemon and adjust — Remove from heat and stir in the fresh lemon juice. Taste and add more salt, pepper, or lemon if needed— this final touch makes the flavors pop!

Recipe Tips and Tricks

Rinse your red lentils well under cold water until the water runs clear to remove any debris and excess starch for a cleaner taste. Sauté the vegetables until they’re nicely softened and fragrant before adding spices—this builds deep flavor quickly.

Keep the soup at a gentle simmer rather than a rolling boil to prevent the lentils from turning to complete mush too soon. Taste and adjust seasoning at the end, as broths vary in saltiness. For extra creaminess without dairy, stir in a spoonful of coconut milk or yogurt (if not vegan).

A quick squeeze of fresh lemon juice right before serving brightens everything beautifully. If the soup thickens too much upon standing, simply thin it with a splash of water or broth when reheating.

Ingredients Notes

Red lentils are the star here—they’re split and hulled, which means they cook much faster than other lentils and break down into a naturally thick, comforting soup base full of plant-based protein and fiber. Use dried red lentils (often labeled as split red lentils or masoor dal) for the best texture.

Fresh onion, carrots, and garlic provide a sweet, savory foundation; the carrots add subtle sweetness and beautiful color. Olive oil or any neutral oil carries the flavors during sautéing. Ground cumin brings warm, earthy notes typical of Middle Eastern and Indian-inspired lentil dishes, while a touch of smoked paprika or chili powder adds gentle heat and depth.

Vegetable broth (or chicken broth if not vegan) forms the liquid base—choose low-sodium so you can control the salt. Tomato paste or diced tomatoes contribute tangy richness and a lovely red hue.

Fresh lemon juice is essential for that final bright lift that makes the soup sing. Salt and black pepper tie everything together, and optional fresh herbs like parsley or cilantro add freshness when serving.

Variations and Substitutions

This versatile soup welcomes many tweaks to suit your taste or pantry. For a spicier kick, add a pinch of cayenne, red pepper flakes, or harissa paste during sautéing. Swap cumin for curry powder, turmeric, or coriander to shift the flavor toward Indian or Thai-inspired profiles. Add diced potatoes, sweet potatoes, or spinach in the last 10 minutes for extra heartiness and nutrition.

If you prefer a chunkier texture, use whole red lentils or mix in some green or brown lentils (they’ll hold their shape better but may need slightly longer cooking). For a creamier version, blend half the soup with an immersion blender or stir in coconut milk toward the end.

Tomato lovers can add a can of diced tomatoes or more tomato paste. Make it heartier by including cooked rice, quinoa, or chickpeas. To keep it oil-free, sauté vegetables in a splash of broth instead. For non-vegan versions, use chicken broth and top with a dollop of Greek yogurt or crumbled feta.

Storage Options

Allow the soup to cool completely before storing. Refrigerate in an airtight container for up to 4-5 days—the flavors often improve as it sits. For longer storage, freeze in portioned containers or freezer bags for up to 3 months.

Thaw overnight in the fridge or reheat directly from frozen on the stovetop, adding a little water or broth to loosen the thickened soup as needed. It reheats beautifully in the microwave too.
