Ingredients
2 tablespoons olive oil
1 large yellow onion, diced
3 garlic cloves, minced
2 carrots, chopped
2 celery stalks, chopped
2 medium potatoes, diced
1 can (14 oz) chopped tomatoes
1 1/2 cups brown or green lentils, rinsed
6 cups vegetable broth
1 bay leaf
1 teaspoon dried thyme
1 teaspoon ground cumin
1 teaspoon salt (or to taste)
1/2 teaspoon black pepper
2 cups fresh spinach
1 tablespoon lemon juice
Instructions
1. Heat olive oil in a large pot over medium heat. Add the onion, carrots, and celery. Sauté for 5–7 minutes until softened.
2. Stir in the garlic, cumin, thyme, salt, and pepper. Cook for 1 minute until fragrant.
3. Add lentils, potatoes, and chopped tomatoes (with juices). Stir well.
4. Pour in the vegetable broth and add the bay leaf. Bring to a boil, then reduce to a simmer. Cover and cook for 30–35 minutes until lentils and potatoes are tender.
5. Remove the bay leaf. Stir in fresh spinach and cook until wilted, about 2–3 minutes.
6. Add lemon juice, taste, and adjust seasoning as needed. Serve hot with crusty bread.
Notes
Use brown or green lentils for the best texture — they hold up well without turning mushy.
The soup gets better the next day as flavors develop, making it perfect for meal prep.
Don’t forget the lemon juice at the end — it lifts all the flavors and balances the richness.
