- Preheat your oven to 350 degrees F (175 degrees C).
- In a pot, cover the chicken with water and bring it to a boil. Simmer for about 15 minutes until no longer pink.
- While the chicken cooks, boil a large pot of lightly salted water and cook the penne for about 11 minutes or until tender yet firm. Drain it.
- Once the chicken is done, drain it and cut it into bite-sized pieces.
- In a large bowl, stir together the chicken, cooked pasta, **alfredo sauce**, 1/2 cup of mozzarella cheese, milk, onion powder, and garlic powder.
- Pour the mixture into a 1.5-quart baking dish and top with the remaining mozzarella and Cheddar cheeses.
- Bake in the preheated oven for about 25 minutes, or until the cheese is melted and bubbly.
Pro Tips for Perfecting Your Casserole

- Use a Meat Thermometer: Ensure your chicken is cooked thoroughly by checking that it reaches an internal temperature of 165°F.
- Add Vegetables: Incorporate veggies like broccoli or spinach for added nutrition and flavor.
- Experiment with Sauces: Mix in a little **chicken broth** with your **alfredo sauce** for a lighter option.
- Layer Wisely: To prevent the top from browning too quickly, cover the casserole with foil during the first half of baking.
- Let it Rest: After baking, let the casserole sit for about 5-10 minutes to set before serving.
- Garnish: Top with fresh herbs like parsley or basil for a pop of color and flavor before serving.
- Make It Ahead: Prepare the casserole a day in advance and store it in the fridge, then bake it when you’re ready.
- Freezing Instructions: This casserole freezes well! Just wrap it tightly in plastic wrap and aluminum foil before freezing.
Common Mistakes and Troubleshooting
Even experienced cooks can make mistakes. Here’s how to avoid common pitfalls:
- Overcooking the Chicken: Keep an eye on it; overcooked chicken can become dry. Remove it as soon as it reaches 165°F.
- Undercooked Pasta: Ensure the pasta is cooked al dente; it will continue to cook in the oven.
- Too Much Sauce: If your casserole is too runny, you can balance it by adding more pasta or cheese.
- Burnt Cheese: If the cheese browns too quickly, cover the casserole with foil to prevent burning.
