Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch casserole dish and set aside.
Cook the penne pasta in a large pot of salted boiling water until al dente according to package instructions. Drain and set aside.
While the pasta cooks, season the chicken breasts with a pinch of salt, black pepper, and half the Italian seasoning. In a large skillet over medium heat, cook the chicken breasts for about 4-5 minutes per side, or until fully cooked through. Remove from heat, let cool slightly, then shred or dice the chicken into bite-sized pieces.
In the same skillet, melt the butter over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant.
Whisk in the flour and cook for 1-2 minutes to form a roux. Slowly pour in the heavy cream and whole milk, whisking constantly to prevent lumps.
Add the grated Parmesan cheese and cream cheese cubes. Stir until melted and the sauce is smooth. Season with salt, black pepper, and remaining Italian seasoning.
In a large mixing bowl, combine the cooked pasta, shredded chicken, and Alfredo sauce. Mix until everything is evenly coated.
Pour half of the mixture into the prepared casserole dish. Sprinkle 1 cup of shredded mozzarella cheese evenly over the layer. Add the remaining pasta mixture on top and sprinkle the remaining 1 cup of mozzarella cheese.
Cover the casserole dish with foil and bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese on top is melted and bubbly.
Remove the casserole from the oven and let it sit for 5 minutes. Garnish with fresh parsley if desired, then serve hot and enjoy!
