How to Make the Recipe
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish with a little olive oil or cooking spray.

Step 2: Prepare the Pasta and Chicken
If you haven’t already, cook the pasta according to package directions and drain. Shred or dice your cooked chicken and set it aside.
Step 3: Sauté the Garlic
In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1-2 minutes, or until fragrant.
Step 4: Combine the Ingredients
In a large bowl, combine the cooked pasta, chicken, Alfredo sauce, sautéed garlic, and peas (if using). Stir in the mozzarella cheese and half of the grated Parmesan cheese. Season with salt and pepper to taste.
Step 5: Assemble the Casserole
Transfer the mixture into the prepared baking dish and spread it evenly. Sprinkle the remaining Parmesan cheese over the top.
Step 6: Bake
Cover the dish with aluminum foil and bake for 20 minutes. Then, remove the foil and bake for an additional 10 minutes, or until the top is golden and bubbly.
Step 7: Garnish and Serve
Once the casserole is done, remove it from the oven and let it cool slightly. Garnish with fresh parsley before serving.
Tips for Making the Recipe
- Use Rotisserie Chicken: For a quicker option, use store-bought rotisserie chicken instead of cooking and shredding your own chicken.
- Add More Cheese: For an extra cheesy casserole, feel free to add more mozzarella or Parmesan cheese on top before baking.
- Use a Homemade Alfredo Sauce: If you have time, try making your own Alfredo sauce for an even richer flavor.
- Don’t Overcook the Pasta: Since the pasta will continue to cook while baking, be sure to cook it al dente before assembling the casserole.
How to Serve
This Chicken Alfredo Casserole is a complete meal on its own, but it pairs beautifully with a side of garlic bread or a simple green salad. For a balanced meal, serve it with some roasted vegetables, like broccoli or carrots.
