How to Make Chicken Alfredo Casserole Step by Step

Preheat the oven to 350°F (175°C).
Cook the chicken: Place it in a pot of water, bring to a boil, and simmer until fully cooked, about 15 minutes. Drain and chop into bite-sized pieces.
Prepare the pasta: In a separate pot, cook the penne in salted water until al dente, about 11 minutes. Drain well.
Combine ingredients: In a large mixing bowl, combine chicken, pasta, Alfredo sauce, half of the mozzarella, milk, onion powder, and garlic powder. Stir until well coated.
Assemble the casserole: Transfer the mixture into a greased baking dish. Sprinkle the remaining mozzarella and all the Cheddar cheese on top for a rich, golden crust.
Bake: Place the dish in the oven and bake for about 25 minutes, or until the top is bubbly and slightly browned.
Serve: Let it cool for 5 minutes before serving to allow the sauce to thicken slightly.

Pro Tips for the Perfect Chicken Alfredo Casserole

• Use fresh cheese: Pre-shredded cheese may contain anti-caking agents that prevent smooth melting.
• Avoid overcooking pasta: Slightly undercook it before baking so it stays firm after baking.
• Mix sauce evenly: Toss pasta thoroughly with sauce to ensure every bite is coated.
• Double the batch: This casserole freezes beautifully; store it in freezer-safe containers for up to 2 months.
• Reheat gently: Warm leftovers in the oven or microwave with a splash of milk to restore creaminess.

Delicious Pairings and Fun Variations

• Serve With: A crisp Caesar salad or garlic bread complements the creamy casserole beautifully.
• Spicy Kick: Add red pepper flakes or a pinch of cayenne for a little heat.
• Veggie Boost: Stir in steamed broccoli, spinach, or peas for color and nutrition.
• Bacon Twist: Sprinkle crumbled bacon on top for extra flavor and crunch.
• Make-Ahead Tip: Assemble the casserole a day in advance, cover tightly, and refrigerate until ready to bake.
