Bring a large pot of salted water to a boil. Add the penne pasta and cook until just al dente, about 9-11 minutes. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for 1-2 minutes until fragrant but not browned. Pour in the heavy cream and stir gently to combine.
Lower the heat and slowly whisk in the grated Parmesan cheese until melted and smooth. Add salt, black pepper, and Italian seasoning. Stir well to blend the flavors into a creamy sauce.
In a large mixing bowl, combine the drained penne pasta, shredded chicken, and crumbled turkey bacon. Pour the Alfredo sauce over the mixture and toss gently to coat evenly.
Preheat oven to 350°F (175°C). Transfer the pasta mixture into a greased 9x13 inch baking dish. Sprinkle shredded mozzarella cheese evenly on top. Bake uncovered for 20-25 minutes until cheese is melted, bubbly, and golden.
Remove from oven and let cool for a few minutes. Sprinkle chopped parsley on top for freshness. Serve warm and enjoy.
