Ingredients

2 cups heavy cream

1½ cups chicken broth (or vegetable broth)

1½ cups freshly grated Parmesan cheese

3 cloves garlic, minced

1 teaspoon salt

½ teaspoon black pepper

⅛ teaspoon nutmeg

2 tablespoons butter, cut into pieces

12 ounces pasta (fettuccine or linguine), broken in half

1½ cups cooked chicken, optional

Fresh parsley, chopped (for serving)

Instructions

In the slow cooker, stir together cream, broth, Parmesan, garlic, salt, pepper, and nutmeg.

Add butter and chicken, if using.

Break pasta in half and gently press it down so it’s mostly submerged in the sauce.

Cover and cook on LOW for 2–3 hours, stirring a few times to prevent sticking, until pasta is tender and the sauce is creamy.

Stir well before serving and garnish with fresh parsley.

Notes

Sauce will thicken as it rests — stir in a splash of warm broth or cream if needed.

Freshly grated Parmesan melts best and keeps the sauce smooth.

Add steamed broccoli, peas, or mushrooms during the last 30 minutes for variation.
