In a skillet, heat 1 tablespoon of olive oil over medium-high heat. Once hot, add diced chicken breasts seasoned with poultry seasoning, cooking for 5-7 minutes until golden brown and fully cooked. Ensure the chicken reaches an internal temperature of 165°F. Once done, remove and set aside, allowing the juices to settle as you prepare the garlic bread.

Preheat your oven to 350°F (175°C) to get it ready for toasting. In a bowl, mix 4 tablespoons of melted unsalted butter with 2-3 minced garlic cloves, chopped parsley, and a pinch of crushed red pepper flakes. Spread this garlic mixture generously on halved Italian-style loaves. Place them cut-side up on a baking sheet and toast for 5-10 minutes in the oven until golden and fragrant.

Using the same skillet you cooked the chicken in, melt 2 tablespoons of unsalted butter over medium heat. Add 2 more minced garlic cloves and sauté until fragrant, about 1 minute. Pour in 1 cup of heavy cream, and stir in 1 cup of grated Parmesan cheese. Let the sauce simmer for 3-5 minutes, stirring regularly until it becomes creamy and thickens slightly.

Take the toasted garlic bread from the oven and spread half of the creamy Alfredo sauce across the top. Layer the cooked chicken evenly over the sauce, followed by a generous sprinkle of mozzarella cheese. Drizzle the remaining Alfredo sauce on top, ensuring every bite will be packed with flavor.

Return the assembled Chicken Alfredo Garlic Bread to the oven for an additional 5 minutes, or until the mozzarella cheese is melted and bubbly. Keep an eye on it to prevent burning.

Once baked, let the Chicken Alfredo Garlic Bread cool for a minute before slicing into servings. Optionally, garnish with additional chopped parsley for a burst of color and flavor. Serve warm, and watch it disappear as everyone enjoys this comforting meal!
