For 6 servings
**Prepare Vegetables:** Dice the onion, carrots, and celery into small, uniform pieces. Mince the garlic. Rinse the brown or green lentils thoroughly under cold running water in a fine-mesh sieve until the water runs clear.
**Sauté Aromatics:** Heat the olive oil in a large heavy-bottomed pot or Dutch oven over medium heat. Add the chopped onion, carrots, and celery. Sauté for 5-7 minutes, stirring occasionally, until the vegetables begin to soften.
**Add Garlic and Herbs:** Stir in the minced garlic and dried thyme. Cook for another 1 minute until fragrant, being careful not to burn the garlic.
**Combine Main Ingredients:** Add the rinsed lentils, the entire can of diced tomatoes (undrained), vegetable broth, and bay leaf to the pot. Stir well to combine all ingredients.
**Simmer the Soup:** Bring the soup to a rolling boil over medium-high heat. Once boiling, reduce the heat to low, cover the pot, and let it simmer for 20-25 minutes, or until the lentils are tender and have absorbed some of the liquid. Stir occasionally to prevent sticking.
**Finish with Greens:** Remove and discard the bay leaf from the soup. Stir in the fresh spinach until it wilts, which should only take 1-2 minutes.
**Season and Serve:** Season the soup with salt and freshly ground black pepper to taste. Ladle the hot soup into bowls and serve immediately, optionally garnished with a drizzle of olive oil or a squeeze of fresh lemon juice.
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1**Don't Skip Rinsing Lentils:** Rinsing lentils thoroughly removes any debris and helps prevent the soup from becoming cloudy or foamy during cooking.
- 2**Adjust Consistency:** If you prefer a thicker soup, you can mash a portion of the cooked lentils against the side of the pot with a spoon, or use an immersion blender for a few pulses. For a thinner soup, add a little more vegetable broth or water.
- 3**Batch Cooking & Freezing:** This soup freezes beautifully! Make a double batch and freeze individual portions in airtight containers for quick, healthy meals later. Thaw overnight in the fridge and reheat gently on the stovetop.
- 4**Enhance Umami:** For an extra layer of savory depth, add a parmesan rind to the soup while it simmers (remove before serving if vegetarian/vegan).

Frequently asked questions
While you can, red lentils cook much faster and tend to break down more, creating a creamier, thicker soup rather than one with distinct lentil pieces. If using red lentils, reduce the simmering time to 15-20 minutes and monitor closely.
