Cook Mode Prevent your screen from going dark

Instructions

1. Place the lentils in a fine-mesh sieve and rinse under cool water until it runs clear; drain well.

2. Heat the olive oil in a skillet over medium heat. Sauté onion, carrots, and celery with a pinch of salt for 5–6 minutes until softened. Stir in garlic and tomato paste; cook 1 minute until fragrant.

3. Add the sautéed vegetables (or raw, if skipping sauté), lentils, crushed tomatoes, broth, bay leaf, cumin, smoked paprika, thyme, coriander (if using), pepper, salt, and red pepper flakes to a 5–6 quart slow cooker; stir to combine.

4. Cover and cook on LOW for 6–8 hours or on HIGH for 3–4 hours, until lentils are tender and the stew is thickened.

5. Remove the bay leaf. Stir in chopped spinach to wilt, then add lemon juice. Taste and adjust salt, pepper, and acidity.

6. Ladle into bowls and top with parsley. Add extra lemon if desired. Serve with crusty bread or over rice.

Notes

For a creamier texture, mash a ladle of lentils into the pot before serving. If using red lentils, reduce cook time by 45–60 minutes. Add more broth to loosen leftovers when reheating.

How to build deep flavor in Slow Cooker Lentil Stew

Slow Cooker Lentil Stew thrives on simple ingredients that deliver big, cozy flavor.

This step unlocks smoky, savory depth without complicating your day. Crushed tomatoes add body and gentle acidity, balancing the earthy lentils. Vegetable broth keeps it plant-based and budget-friendly. The secret to irresistibly hearty Slow Cooker Lentil Stew is layering: aromatics first, then lentils, then broth, with a final flourish of lemon and parsley to brighten every spoonful. It’s the kind of crockpot lentil stew that feels slow-simmered all afternoon because it was—while you were off doing everything else.
