Each component plays a significant role in creating the rich, comforting flavors that define this dish.

- 1 (16-oz) package penne pasta: This pasta provides a sturdy base for the casserole, holding onto all that creamy sauce.
- 4 cups cooked chopped chicken: Tender and juicy, the chicken adds protein and heartiness to the dish.
- 2 Tbsp minced onion flakes: They contribute a mild, sweet onion flavor that enhances the overall taste.
- 2 (15-oz) jars Alfredo sauce: This is the key to creaminess, making the casserole rich and indulgent.
- 1½ cups salsa: The salsa adds a zesty kick that perfectly balances the creaminess of the sauce.
- 1 cup ricotta cheese: Ricotta provides a lovely texture and additional creaminess to the dish.

How to Assemble Mexican Chicken Alfredo Casserole

Creating the Mexican Chicken Alfredo Casserole is as easy as it is rewarding. You’ll love the seamless process that leads to a comforting, bubbling dish. Let’s dive into the steps that will bring this casserole to life!
First, preheat your oven to 350ºF. This ensures that your casserole will bake evenly and help achieve that wonderful bubbly texture. While the oven heats, lightly spray a 9×13-inch baking dish with cooking spray to prevent sticking.
Next, cook the penne pasta according to the package directions. Once it’s al dente, drain it and set it aside. It’s important not to overcook it, as it will continue to cook in the oven.
In a large mixing bowl, combine the cooked chicken, onion flakes, Alfredo sauce, salsa, ricotta cheese, and taco seasoning. This mixture is where the magic starts to happen! Stir everything together until well combined, ensuring every piece of chicken is coated.
Now, add the cooked pasta to the chicken mixture. Stir gently to incorporate the pasta, making sure it’s evenly distributed in the creamy sauce.
Spread the mixture into the prepared baking dish, smoothing it out so it’s evenly layered. This is key for an even bake and to have all components enjoy the heat.
Top the casserole with the Parmesan cheese, covering it generously. This will create a deliciously cheesy, crispy top once baked.
Cover the baking dish with foil. This helps trap moisture during the initial baking period, which prevents the casserole from drying out.
Place the dish in the oven and bake for about 50 to 60 minutes, until it’s bubbly and heated through. Halfway through, you can remove the foil to allow the top to brown if you like it extra crispy.
Once done, remove from the oven and allow it to cool for a few minutes. This helps the casserole set slightly, making it easier to serve.
Things Worth Knowing
- The Alfredo sauce can be made from scratch if you prefer fresher flavors, using butter, cream, and Parmesan cheese.
- For an extra kick, consider adding diced jalapeños or black olives into the mix before baking.
- If you want a lower-carb option, you can substitute the penne pasta with zucchini noodles.
- Experiment with different cheeses on top, like Monterey Jack or a Mexican blend, for varied flavors.
Tips and Variations

There are many ways to enjoy and customize your Mexican Chicken Alfredo Casserole. Here are some tips to help you make the most of this delicious dish:

- Freezing: To freeze, wrap the casserole tightly in plastic wrap and then in aluminum foil. It can be frozen for up to two months. Thaw completely before baking.
- Pairing: Serve this casserole with a fresh salad or warm tortillas for a complete meal. A side of guacamole can also enhance the experience.
