Step-by-Step Instructions
-
Cook the pasta
Boil the pasta in salted water until just al dente. Remember, it will continue cooking in the oven, so slightly undercooking it keeps the texture perfect. -
Prepare the chicken
Use leftover cooked chicken, or quickly pan-sear chicken breasts with salt and pepper, then shred or dice. -
Make (or warm) the Alfredo sauce
If making from scratch, melt butter in a saucepan, sauté garlic until fragrant, then stir in heavy cream and Parmesan cheese. Whisk until smooth and creamy. -
Combine everything
In a large mixing bowl, toss the pasta, chicken, Alfredo sauce, and any vegetables. Add half the mozzarella and Parmesan, mixing well. -
Assemble the casserole
Transfer the mixture to a greased baking dish. Sprinkle the remaining cheese over the top for that golden, bubbly crust. -
Bake
Bake at 375°F (190°C) for about 20–25 minutes, or until the casserole is hot and the cheese topping is golden and slightly crispy. -
Serve
Let it rest for 5 minutes before serving. Garnish with fresh parsley for a pop of color and freshness.
Tips for Success
-
Don’t skip the cheese topping: It creates a delicious crust and seals in the creaminess.
-
Use a mix of cheeses: Adding provolone, fontina, or cheddar alongside mozzarella can create a deeper flavor.
-
Make it ahead: Assemble the casserole earlier in the day, cover, and refrigerate. Bake when ready to serve, adding 5–10 extra minutes of baking time.
Serving Ideas
Pair this casserole with a crisp green salad and garlic bread for a complete meal. For a lighter option, serve alongside roasted vegetables instead of bread.
