My favorite part is the cheddar cheese which melts into the pasta creating pockets of gooey goodness. I still remember how this dish became a tradition at our family reunions where laughter and casserole always went hand in hand.

Storage Tips

Leftovers keep well in the fridge for up to three days in an airtight container. Reheat gently in the oven to maintain creamy texture or in the microwave for convenience.

Ingredient Substitutions

You can replace chicken with shrimp for a seafood twist. Rotini or penne pasta also works beautifully if you want something heartier. For extra creaminess stir in a little cream cheese.

Serving Suggestions

Serve this casserole with a fresh green salad or roasted vegetables to balance the richness. It also pairs wonderfully with garlic bread for a complete comforting meal.
