Instructions
Heat the olive oil in a Dutch oven over medium heat. Add the ground sausage and cook until browned, breaking it into crumbles with a spoon (5–7 minutes). Remove the sausage and set it aside.
In the same pot, add the onion, carrot, and celery. Cook until the vegetables are softened (about 5 minutes). Stir in the garlic and sauté for an additional minute until fragrant.
Add the lentils, diced tomatoes (with juice), chicken broth, Italian seasoning, bay leaf, and the browned sausage back into the pot. Season with salt, pepper, and red pepper flakes, if desired. Bring to a boil, then reduce the heat and let the soup simmer for 30–35 minutes, or until the lentils are tender.
Remove the bay leaf and stir in the fresh spinach. Cook until the spinach wilts (2–3 minutes). Adjust seasoning to taste.
Serve hot, garnished with freshly grated Parmesan cheese, and enjoy with crusty bread or a side salad for a complete meal.
Notes
Cooking NotesBrown the sausage first so it builds flavor in the soup base. Let the lentils simmer gently so they soften without breaking apart. Stir in the spinach during the last few minutes so it stays bright and tender.Tips for Best Results
Rinse the lentils before cooking to remove excess starch and debris.
Simmer the soup gently so the lentils cook evenly without splitting.
Taste and adjust salt after the soup finishes simmering since sausage already contains seasoning.
Add spinach only during the final few minutes of cooking.
How to Know It’s ReadyThe lentils should be tender but still hold their shape. The broth will appear slightly thicker and the spinach should be wilted and bright green.
