Smoked Turkey and Lentil Soup Recipe for Slow Cooker

When the air turns crisp I start cooking more hearty, comforting dishes, and few things are as warming as a steaming bowl of soup. This crock pot lentil soup is ideal for busy weeknights—add the ingredients to the slow cooker in the morning, set it, and return to a rich, flavorful meal at dinnertime.

Slow cookers are perfect for soups: the low-and-slow heat lets flavors meld while you go about your day. By evening the lentils, vegetables and smoked turkey will have transformed into a satisfying, aromatic broth. This lentil soup is substantial enough to be a full meal—no light consommé here.

For this recipe I use a smoked turkey thigh, which is commonly available at grocery stores alongside smoked turkey drumsticks. Smoked turkey is an excellent alternative to ham and can replace it in many recipes. The smoked thigh gives the soup a deep, smoky backbone and plenty of meaty texture for those who like a hearty bowl.

What kind of lentils to use

Lentils are legumes known for their small, flattened shape and quick cooking time. They’re excellent in soups, stews and curries. For this crock pot soup I recommend dry whole green (or brown) lentils. Unlike split lentils that break down and thicken the broth, whole lentils hold their shape during long cooking, giving the soup pleasant texture and distinct bites.

This recipe is loaded with vegetables: carrots, celery, diced plum tomatoes and onion all add sweetness, depth and body to every spoonful. Minced garlic, thyme, salt and pepper round out the seasoning, while grated pecorino romano and chopped fresh parsley used at the end brighten and finish the bowl.

How long in the slow cooker?

Place all ingredients (except the grated cheese and parsley) into the slow cooker and cover with water or chicken broth. Set the Crock Pot to high and cook for 6 hours. The long simmer extracts flavor from the smoked turkey and allows the lentils and vegetables to become tender and flavorful.

About one hour before serving, remove the smoked turkey thigh from the slow cooker and let it cool enough to handle. Discard the skin, strip the meat from the bone, and dice it into small pieces. Return the chopped turkey to the slow cooker, stir, replace the lid, and let the soup finish cooking for the final hour.

Adjusting the broth

After you stir the turkey back in, check the consistency of the broth. Whole lentils absorb a lot of liquid; if the soup feels too thick you can add a little extra water or broth to reach the consistency you prefer. I tend to keep it hearty, but thinning is easy if needed.

Serve the soup hot, garnished with grated pecorino romano and chopped fresh parsley. These finishing touches add saltiness and brightness that elevate each spoonful. I like to serve this soup with warm biscuits for dipping—the combination is deeply satisfying on a cold evening.
