Ingredients
- 1 ½ cups dried brown lentils, rinsed and sorted
- 1 large yellow onion, finely diced
- 3 medium carrots, peeled and diced
- 2 cloves garlic, minced
- 3 stalks celery, diced
- 1 can (14 oz) diced tomatoes, with juices
- 6 cups vegetable broth (low sodium preferred)
- 2 teaspoons ground cumin
- 1 teaspoon smoked paprika
- 1 teaspoon dried thyme
- 1 bay leaf
- Salt and black pepper to taste
- 2 tablespoons olive oil
- Juice of ½ lemon (optional, to brighten flavor)
- Fresh parsley and cilantro for garnish
Instructions
- Prepare the base: Heat olive oil in a skillet over medium heat. Add the diced onions, carrots, and celery. Sauté until softened and fragrant about 5 minutes-stirring occasionally to prevent sticking.
- Add garlic and spices: Stir in minced garlic, cumin, smoked paprika, and dried thyme. Cook for another 1-2 minutes until the spices bloom and release their aromas.
- Transfer to slow cooker: Pour the sautéed vegetables and spices into the slow cooker. Add the rinsed lentils, diced tomatoes (with juices), and vegetable broth. Drop in the bay leaf.
- Slow cook to perfection: Set the slow cooker on low and cook for 6 to 8 hours, until lentils are tender and flavors meld beautifully. For a thicker soup, cook uncovered during the last hour.
- Season and finish: Remove bay leaf. Stir in lemon juice to help balance the earthiness. Taste and adjust seasoning with salt and black pepper.
Tips for Success

- herbs and spices: Fresh herbs like parsley and cilantro added at the end brighten the dish and add layered freshness.
- Make ahead: This soup tastes even better the next day, making it ideal for meal prep. Store leftovers in an airtight container in the fridge for up to 4 days.
- Adjust thickness: For a chunkier soup, reserve some lentils and vegetables before blending part of the soup to a creamy consistency, then mix back in.
