How to Make Italian Sausage & Lentil Soup
Step 1: Brown the Sausage
In a large soup pot, heat olive oil over medium heat. Add sausage and cook until browned, about 6–7 minutes, breaking it up with a spoon.
Step 2: Sauté Aromatics
Add diced onion, carrots, and garlic. Cook for 5 minutes until vegetables begin to soften and become fragrant.
Step 3: Add Core Ingredients
Stir in crushed tomatoes, lentils, broth, oregano, thyme, bay leaf, and red pepper flakes (if using). Bring to a boil.
Step 4: Simmer to Perfection
Reduce heat to low, cover, and simmer for 30–35 minutes until lentils are tender and the soup is thickened. Stir occasionally.
Step 5: Finish with Greens
Stir in chopped spinach or kale and simmer 2–3 more minutes until wilted. Discard the bay leaf, taste, and season with salt and pepper.
Step 6: Serve
Ladle hot soup into bowls and top with grated Parmesan or fresh basil if desired. Serve with crusty bread for a complete meal.

Frequently Asked Questions
Can I use red lentils?
Red lentils break down more and create a creamier texture. For a heartier soup, stick with brown or green lentils.
What kind of sausage is best?
Italian pork or chicken sausage works well. For a leaner or vegan option, go with turkey or soy-based links.
Can I make this in a slow cooker?
Yes! Brown sausage first, then add all ingredients to the slow cooker and cook on low for 6–7 hours.
Is it gluten-free?
Yes—just ensure your sausage and broth are gluten-free.
Can kids eat this?
Absolutely. Choose mild sausage and skip the red pepper flakes for a kid-friendly version.
