Ingredients You’ll Need

Soup Base

1 cup red lentils, rinsed – Provides protein and creates the soup’s creamy body as they break down during cooking.
3 tablespoons olive oil – Adds richness and acts as the flavor carrier for aromatics and spices.
1 large onion, finely chopped – Builds a sweet, savory foundation when gently sautéed.
4 cloves garlic, minced – Adds depth and aromatic intensity.
2 medium carrots, diced – Contributes subtle sweetness, texture, and color.

Liquid & Seasoning

6 cups vegetable broth – Forms the cooking liquid and enhances overall savoriness.
1 teaspoon ground cumin – Adds warm, earthy notes typical of Mediterranean and Middle Eastern cooking.
½ teaspoon turmeric – Provides gentle bitterness, color, and anti-inflammatory benefits.
Salt and black pepper, to taste – Balances and sharpens flavors throughout the soup.

Finishing & Garnish

Juice of 2 medium lemons – Brightens the soup and balances the richness of the lentils.
Fresh parsley, chopped – Adds freshness and herbal contrast.
Red pepper flakes, to taste – Introduces optional heat and complexity.

Step-by-Step Instructions

Sauté the Aromatics
Heat olive oil in a large pot over medium heat, then cook the chopped onion for about 5 minutes until soft and translucent. Add the garlic and cook for 1 minute, stirring constantly to prevent browning.
Bloom the Spices
Stir in the cumin and turmeric, cooking for 30 seconds until fragrant. This step releases essential oils from the spices, intensifying their flavor.
Add Vegetables
Add the diced carrots and stir to coat them evenly in the spiced oil, allowing them to soften slightly and absorb flavor.
Simmer the Soup
Add the rinsed red lentils and vegetable broth, then bring to a gentle boil. Reduce heat to low and simmer for 25–30 minutes, stirring occasionally, until the lentils are fully tender and the soup becomes thick and creamy.
Finish with Lemon & Seasoning
Remove the pot from heat and stir in the fresh lemon juice. Season with salt and black pepper, adjusting consistency with additional broth or water if needed.
Serve & Garnish
Ladle into bowls and garnish with chopped parsley, red pepper flakes, and lemon slices. Serve hot.

Recipe Notes & Tips

Choosing the Right Lentils – Red lentils are essential for this texture; green or brown lentils require longer cooking and won’t break down the same way.
Spice Timing Matters – Blooming spices in oil enhances flavor and prevents a raw, powdery taste.
Lemon at the End – Adding citrus after cooking preserves acidity and brightness.
Consistency Control – Simmer uncovered for a thicker soup or thin with broth at the end if needed.
Flavor Development – The soup tastes even better the next day as the flavors meld.
Freezer-Friendly – Freeze in airtight containers for up to 3 months; reheat gently.
