Ingredients and Variations

STUFFING: Dry stuffing mixes like stove top come in a variety of savory flavors, including cornbread – any kind will do! Feel free to add croutons or leftover bread that can be torn or cut up.

SPINACH: Broccoli, kale, mushrooms, chopped zucchini, carrots or a frozen vegetable medley add color and flavor. Sliced water chestnuts, pecans, and cranberries are good holiday add-in options.

CHEESE: Cheddar cheese has a bold flavor and is extra creamy when it melts, which also helps hold the casserole together when cutting into squares. White cheeses like Monterey jack or a sharp white cheddar are great, too!

SEASONINGS: If the stuffing mix is unseasoned, add extra Italian seasonings.
