Ingredients
- 2 cups cooked rotini pasta
Rotini holds onto the creamy sauce well thanks to its spiral shape. Using cooked pasta ensures that your casserole has the right texture without overcooking it in the oven. - 2 cups cooked and shredded chicken
Shredded chicken adds protein and moisture to the dish. Using leftover rotisserie chicken makes preparation quick and adds depth of flavor. - 2 cups Alfredo sauce
Alfredo sauce serves as the creamy base for the casserole. It adds rich flavor and helps bind the ingredients together, creating a luscious texture. - 1 cup broccoli florets (fresh or frozen)
Broccoli adds a nutritious element and a pop of color to the casserole. It balances the richness of the sauce while providing essential vitamins. - 1 cup shredded mozzarella cheese
Mozzarella melts beautifully, creating a gooey, cheesy layer that makes the casserole irresistible. It also adds a mild flavor that complements the dish. - 1/2 cup grated Parmesan cheese
Parmesan contributes a sharp, nutty flavor, enhancing the overall taste of the casserole. It also helps achieve a golden crust when baked. - 1/2 teaspoon garlic powder
Garlic powder adds a warm, savory note that elevates the flavor profile. It also allows for even distribution of garlic flavor throughout the casserole. - 1/2 teaspoon Italian seasoning
Italian seasoning brings a mix of herbs that adds complexity and aroma to the dish. Its blend of flavors complements the chicken and sauce perfectly. - Salt and pepper to taste
Seasoning the casserole properly enhances all the flavors. Adjusting salt and pepper to your preference ensures a well-balanced dish.
Directions & Preparation
Step 1: Preheat your oven to 350°F (175°C).
Preheating the oven is essential for ensuring even cooking of the casserole. An adequately heated oven allows the dish to bake and bubble uniformly without drying out the ingredients.
Step 2: Cook the rotini pasta according to package instructions until al dente. Drain and set aside.
Cooking the pasta just until al dente ensures it won’t become mushy during baking. The slight firmness allows the pasta to absorb the creamy sauce while still retaining some bite.
Step 3: In a large mixing bowl, combine the cooked rotini, shredded chicken, broccoli, Alfredo sauce, garlic powder, Italian seasoning, salt, and pepper.
Mixing all ingredients in a bowl ensures every component is evenly coated with the Alfredo sauce. This step is crucial for flavor distribution and achieving a creamy consistency throughout.
Step 4: Transfer the mixture into a greased 9×13-inch baking dish, spreading it evenly.
Spreading the mixture evenly in the baking dish ensures that it cooks uniformly, allowing the top to crisp while the insides remain creamy. Greasing the dish beforehand prevents sticking and makes serving easier.
Step 5: Top the casserole with shredded mozzarella and grated Parmesan cheese.
Adding cheese on top creates a delicious, cheesy crust that enhances texture and flavor. The combination of mozzarella and Parmesan adds creaminess and a slight nuttiness.
Step 6: Bake in the preheated oven for 25-30 minutes, or until the cheese is melted and bubbly.
Baking allows all the flavors to meld together and the cheese to create a golden, crispy topping. Keep an eye on it to avoid over-browning while ensuring the cheese is properly melted.
Step 7: Remove from the oven and let cool for a few minutes before serving.
Allowing the casserole to cool slightly makes it easier to serve and helps the layers set. This wait also enhances the flavors as they develop further upon resting.

Variety in Your Casserole
One of the best things about the Chicken Alfredo Casserole is its adaptability. You can easily incorporate different vegetables or swap out the chicken for turkey, shrimp, or even a plant-based protein for a variation. Adding vegetables such as spinach, bell peppers, or sun-dried tomatoes not only boosts the nutritional content but also brings in different flavors and textures.
Cheese Lovers Rejoice
For those who can’t get enough cheese, consider boosting the cheesy aspect of your casserole. Enhance the mozzarella with additional cheese varieties like Gouda or Gruyère for an extra punch. Mixing cheeses can elevate taste complexity and texture, giving a delightful stretch and richness to the overall dish.
Make It Spicy
If you enjoy a little heat, don’t hesitate to spice up your Chicken Alfredo Casserole. A dash of red pepper flakes or a drizzle of hot sauce in the Alfredo can add a new dimension to the flavor profile. This simple addition can transform the dish, offering a delightful kick that contrasts with the richness of the cream.
FAQs
What can I do if my casserole comes out dry?
If your casserole is dry, consider adding more Alfredo sauce or a splash of chicken broth before baking. This will help retain moisture during cooking.
Can I prepare the casserole ahead of time?
Yes, you can assemble the casserole a day in advance. Just cover it tightly and refrigerate, then bake when ready, adding extra time in the oven if baking straight from cold.
What should I do if my sauce is too thick?
If the Alfredo sauce is too thick, add a bit of milk or chicken broth to reach your desired consistency before mixing it into the casserole.
Can I use different types of pasta?
Certainly! While rotini works well for its shape, you could use penne, fusilli, or even elbow macaroni depending on your preference.
What if my chicken isn't seasoned well?
If the chicken lacks flavor, consider marinating it beforehand or seasoning it with salt, pepper, and herbs before mixing into the casserole.
Can I add more vegetables to this casserole?
Absolutely! Feel free to include vegetables like zucchini, peas, or asparagus, adjusting cook times as needed based on what you choose.
