Ingredients

4 tablespoons extra-virgin olive oil 

1 pound kielbasa, cut diagonally into 1/2-inch-thick slices 

1 onion, diced 

2 carrots, sliced 

2 celery stalks, sliced 

7 garlic cloves, chopped 

3 1/2 cups Le Puy lentils (about 2 pounds), rinsed and picked over 

2 cups homemade or low-sodium store-bought chicken stock 

1 dried bay leaf 

3 teaspoons finely chopped fresh rosemary 

Coarse salt and freshly ground pepper 

Preparation

Heat 2 tablespoons oil in a large saucepan over medium-high heat until hot but not smoking. Brown sausage, about 6 minutes. Transfer to a bowl.

Add onion, carrots, celery, and garlic to pan; cook, stirring occasionally, until softened, about 5 minutes.

Stir in the lentils, stock, 3 1/2 cups water, bay leaf, 1 teaspoon rosemary, and remaining 2 tablespoons oil; season with salt. Bring stew to a boil. Reduce heat to medium-low, and simmer until lentils are just tender, about 50 minutes.

Return sausage to the pan; cook until heated through, about 5 minutes. Stir in remaining 2 teaspoons rosemary. Season stew with salt and pepper.
