This delicious, hearty Italian lentil soup with sausage is perfect for a comforting meal. Enjoy the robust flavors from fresh vegetables, savory sausage, and aromatic herbs. This recipe provides options for both stovetop and slow cooker methods.
Heat 2 tablespoons of olive oil in a large pot over medium heat. Add the sausage and cook until browned, breaking it into smaller pieces with a wooden spoon, about 5-7 minutes. Remove the sausage and set it aside.
In the same pot, add the remaining olive oil. Add the diced onion, celery, and carrots. Sauté until softened, about 5 minutes. Add the zucchini and garlic, and cook for another 2-3 minutes.
Stir in the canned diced tomatoes and cook for 2 minutes. Return the sausage to the pot. Add the chicken stock, lentils, bay leaves, and Parmigiano Reggiano rind (if using).
Bring the mixture to a boil, then reduce heat to low and simmer. Cover and cook for 45-50 minutes, or until the lentils are tender. Stir occasionally.
Stir in the parsley and basil, then season with salt and pepper to taste.
Ladle the soup into bowls. Top with freshly grated Parmigiano Reggiano cheese. Enjoy with crusty bread!
Slow Cooker Method
Brown the sausage and the veggies (soffritto) on the stovetop as directed in steps 1-2 above. Add both the meat and veggies to the slow cooker.
Add the canned diced tomatoes, chicken stock, lentils, bay leaves, and Parmigiano Reggiano rind (if using) to the slow cooker.
Cover and cook on low for 6-7 hours or on high for 4-5 hours, until the lentils are tender.
Add the fresh parsley and basil and season with salt and pepper to taste. Serve with grated Parmigiano Reggiano cheese and enjoy with bread!
Notes
Use Quality Ingredients: Opt for high-quality sausage, fresh vegetables, and good chicken stock. The better the ingredients, the richer the flavor.
Brown the Sausage: Make sure to thoroughly brown the sausage. This step adds depth and enhances the overall flavor of the soup.
Sauté the Vegetables: Don’t skip sautéing the onions, celery, carrots, zucchini, and garlic. This process caramelizes the natural sugars and adds a wonderful base flavor.
Include a Parmigiano Reggiano Rind: If you have it, add a Parmigiano Reggiano rind while simmering. It infuses the soup with a rich, umami flavor.
Add Fresh Herbs at the End: Stir in the fresh parsley and basil just before serving. This keeps their flavors vibrant and fresh.
