How to Make Sausage Lentil Soup

Step 1: Brown the Sausage

In a large skillet over medium-high heat, cook the Italian sausage, breaking it into crumbles as it browns. When it’s almost done, add the minced garlic and cook for another minute until fragrant.

Step 2: Combine All Ingredients

Transfer the cooked sausage and garlic to a large Dutch oven. Add the diced onion, chopped celery, carrots, zucchini, chicken broth, diced tomatoes, brown lentils, salt, and pepper.

Step 3: Simmer to Perfection

Bring the mixture to a boil, then reduce the heat to maintain a gentle simmer. Cover the pot and let everything cook together for about an hour, or until the lentils are tender but still hold their shape.

Step 4: Adjust Consistency

If the soup seems too thick after cooking, add a bit of water or additional broth until it reaches your desired consistency. Remember that the soup will continue to thicken as it cools.

Step 5: Garnish and Serve

Ladle the hot soup into bowls and top with fresh basil, oregano, and a generous sprinkle of freshly grated Parmesan cheese if desired.

Pro Tips for Making the Recipe

Don’t Rush the Sausage: Take your time browning the sausage properly – those caramelized bits add tremendous flavor to the final soup.
Check Your Lentils: Before adding lentils to the pot, spread them on a light-colored plate and look for any small stones or debris to remove.
Perfect Texture: Cook the lentils until they’re tender but still slightly firm. Overcooked lentils will turn mushy and affect the soup’s texture.
Taste as You Go: Flavors concentrate as the soup simmers, so taste toward the end of cooking and adjust seasonings if needed.
Let It Rest: If time allows, let the soup sit for 15-20 minutes after cooking – this small pause allows flavors to develop even further.

How to Serve

This Sausage Lentil Soup is a meal in itself, but there are plenty of delicious ways to round out your dinner:

Make It Special:

Make Ahead and Storage

Storing Leftovers

This soup actually improves with time! Store in an airtight container in the refrigerator for up to 5 days. The flavors will continue to develop, making for an even tastier lunch or dinner.

Freezing

This soup freezes beautifully. Allow it to cool completely, then portion into freezer-safe containers, leaving some room for expansion. It will keep for up to 3 months.

Reheating

For refrigerated soup, reheat gently on the stovetop over medium-low heat, stirring occasionally. Add a splash of broth if it’s thickened too much. For frozen soup, thaw overnight in the refrigerator before reheating, or use the defrost setting on your microwave.

FAQs

Can I use red lentils instead of brown lentils?
Brown lentils are ideal for this soup because they hold their shape well during cooking. Red lentils break down much more quickly and will create a different texture – more stew-like and less defined. If you prefer that consistency, go ahead and try red lentils, but reduce the cooking time to about 20-30 minutes.

How can I make this soup in a slow cooker?
This recipe adapts beautifully to a slow cooker! Brown the sausage and garlic as directed, then transfer to your slow cooker along with all remaining ingredients. Cook on low for 7-8 hours or on high for 4-5 hours, until the lentils are tender. Check occasionally to see if you need to add more liquid.

Is this soup gluten-free?
The soup itself contains no gluten ingredients, but always check your specific brands of sausage and broth, as some may contain hidden gluten. Most Italian sausage is gluten-free, but some manufacturers add fillers containing gluten.

Can I use canned lentils to save time?
Absolutely! If using canned lentils, drain and rinse them well, then add them during the last 15-20 minutes of cooking. You’ll also want to reduce the broth by about 2 cups since the lentils won’t be absorbing liquid during cooking.
