Preheat the Oven: Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish.
Cook the Pasta: Cook the pasta according to the package instructions until al dente. Drain and set aside.
Prepare the Alfredo Sauce If you're using store-bought Alfredo sauce, skip to the next step. For homemade sauce, melt 1/2 cup of butter in a saucepan, add 1 cup of heavy cream, and stir in 1 cup of grated Parmesan cheese until smooth. Season with salt and pepper to taste.
Combine Pasta, Chicken, and Sauce: In a large mixing bowl, combine the cooked pasta, shredded chicken, and Alfredo sauce. Add the garlic powder, onion powder, dried Italian herbs, salt, and pepper. Mix well until the pasta and chicken are evenly coated with the sauce.
Layer in the Baking Dish: Transfer half of the pasta mixture into the prepared baking dish. Dollop half of the ricotta cheese evenly over the layer. Sprinkle half of the mozzarella and Parmesan cheeses on top. Repeat the layers with the remaining pasta and cheese.
Bake to Perfection: Place the baking dish in the preheated oven and bake for 20-25 minutes or until the cheese is golden and bubbly. If you like a crispy top, you can broil the dish for an additional 2-3 minutes, but be sure to keep a close eye on it to prevent burning.
Garnish and Serve: Once out of the oven, let the Chicken Alfredo Pasta Bake rest for a few minutes. Garnish with chopped fresh parsley for a burst of color and added freshness. Slice and serve warm.
