Why You’ll Love This Chicken Alfredo Casserole Recipe

This casserole is a family favorite because it’s:

• Quick to Prep: With a prep time of just 10 minutes, it’s the best way to get dinner on the table fast.
• Perfectly Cheesy: Loaded with mozzarella and Parmesan cheese for that cheesy casserole goodness.
• Versatile: Use rotisserie chicken for convenience or leftover chicken breasts for a homemade touch.
• Great for Leftovers: Store leftovers in an airtight container and enjoy them for up to 4 days.

Ingredients You’ll Need

Here’s what makes this casserole so creamy and delicious:

• Rotisserie Chicken: Shredded and ready to go, it saves time without sacrificing flavor.
• Penne Pasta: Perfectly al dente pasta that holds onto the creamy Alfredo sauce.
• Jar of Alfredo Sauce: I love using Rao’s for convenience, but you can also try my homemade Alfredo sauce here.
• Mozzarella and Parmesan Cheese: These two cheeses create a gooey, cheesy topping.
• Optional Additions: Fresh parsley for garnish, garlic bread, and steamed broccoli to complete the meal.

Step-by-Step Instructions

Prep Your Ingredients: Preheat your oven to 375 degrees F and grease a 9×13 casserole dish with cooking spray. Cook your penne pasta until al dente, drain, and set aside.

Mix It All Together: In a large mixing bowl, combine the shredded chicken, cooked pasta, and Alfredo sauce. Stir until everything is well-coated with the creamy sauce.

Assemble the Casserole: Spread the mixture evenly into your prepared baking dish. Top with mozzarella and Parmesan cheese.

Bake to Perfection: Cover the dish with aluminum foil and bake for 25 minutes. Then, remove the foil and bake for an additional 13-15 minutes or until the cheese is golden brown and bubbly.

Serve and Enjoy: Let the casserole cool slightly before serving. Garnish with parsley if desired and pair it with garlic bread and steamed broccoli for a complete meal.

Tips and Tricks for the Best Results

• Pasta Water: If needed, reserve a little pasta water to thin out the sauce.
• Make It Creamier: Add a dollop of sour cream or cream cheese to the sauce mixture for extra richness.
• Homemade Touch: Use my homemade Alfredo sauce recipe with heavy cream, garlic powder, cream cheese, and Parmesan cheese for a delicious sauce.
• Storage Tips: Store leftovers in an airtight container in the fridge for up to 4 days. Reheat individual portions in the microwave for 2 minutes, or bake the entire dish at 350 degrees F for 25 minutes.
• Extra Flavor: Add a pinch of onion powder or garlic powder to the sauce for extra depth of flavor.

Why Using Rotisserie Chicken Is a Game-Changer

Using rotisserie chicken reduces your prep time, so you can focus on other things during busy weeknights. I like to buy a 3-pound pack of shredded rotisserie chicken and freeze them in one-pound bags. If you don’t have a Costco nearby, no worries—a rotisserie chicken from your local grocery store works perfectly. You can also use shredded chicken breasts as a homemade option.

Yes! Assemble the casserole and cover it tightly with aluminum foil. Store it in the fridge for up to 24 hours before baking. Adjust baking time to ensure the middle of the casserole reaches at least 160 degrees.
