How to Make Classic Lentil Soup (Step-by-Step)
1. Sauté Aromatics
Heat the olive oil in a large soup pot or Dutch oven over medium heat. Add the chopped onion, carrots, and celery. Cook for 5–7 minutes until softened and slightly golden. Stir in the garlic and cook for another 1–2 minutes until fragrant.
2. Add Lentils and Spices
Stir in the lentils, cumin, paprika, thyme, and bay leaf. Mix well so the lentils get coated in the aromatic oil and spices.
3. Add Tomatoes and Broth
Pour in the diced tomatoes (with juice) and vegetable broth. Stir everything together, bring the soup to a boil, then reduce the heat to low and cover. Let it simmer for 30–35 minutes, or until the lentils are tender.
4. Season and Finish
Remove the bay leaf and thyme sprigs if using fresh. Season the soup with salt, pepper, and lemon juice. Taste and adjust seasonings as needed.
5. Serve and Enjoy
Ladle the hot lentil soup into bowls, top with fresh parsley, and serve with crusty bread, rice, or a side salad.
