Ingredients

Scale

1 lb Italian sausage

1 cup dry green or brown lentils

3 carrots, diced

2 celery stalks, diced

1 onion, chopped

3 cloves garlic, minced

1 can (14.5 oz) diced tomatoes

2 tbsp tomato paste

4 cups chicken broth

1 tsp Italian seasoning

1 tsp salt (or to taste)

1/2 tsp black pepper

1 bay leaf

1 tbsp olive oil


Instructions

1. Heat olive oil in a skillet over medium-high heat. Add Italian sausage, breaking it into chunks. Cook until browned and no longer pink. Drain excess fat.

2. Add chopped onion, carrots, and celery to the same pan. Sauté for 4–5 minutes, until softened. Stir in minced garlic and tomato paste, and cook for 1 more minute.

3. Transfer sausage and vegetables to a slow cooker. Add lentils, diced tomatoes, chicken broth, Italian seasoning, salt, pepper, and bay leaf. Stir well.

4. Cover and cook on LOW for 7–8 hours or on HIGH for 4–5 hours, until lentils are tender.

5. Remove bay leaf. Taste and adjust seasoning if needed. For a thicker soup, mash a few lentils with the back of a spoon before serving.

6. Serve hot, optionally topped with parsley or Parmesan cheese.


Notes

For a spicier version, use hot Italian sausage.

Add chopped spinach or kale in the last 15 minutes of cooking for extra greens.

This soup freezes well—perfect for batch cooking and storing leftovers.
