Heat a skillet over medium heat and add a drizzle of olive oil. Once hot, add diced chicken breasts seasoned with poultry seasoning. Sauté for about 5–7 minutes, stirring occasionally, until the chicken is golden brown and cooked through.

Preheat your oven to 350°F (175°C). In a small bowl, mix melted unsalted butter, minced garlic, chopped parsley, and crushed red pepper flakes together. Slice the Italian-style loaf in half and spread the garlic mixture generously over each side. Place the loaf on a baking sheet and toast it in the oven for 5–10 minutes or until it turns golden and fragrant.

Using the same skillet from the chicken, melt the remaining butter over medium heat. Add a bit more minced garlic and let it sauté until fragrant—just about 1 minute. Pour in heavy cream, then stir in grated Parmesan cheese and additional parsley. Simmer for 3–5 minutes until the sauce thickens.

Once the garlic bread is toasted, spread half of the creamy Alfredo sauce over the bread. Layer on the sautéed chicken, followed by a generous sprinkle of mozzarella cheese and the remaining Alfredo sauce.

Return your assembled Chicken Alfredo Garlic Bread to the oven and bake at 350°F (175°C) for an additional 5 minutes, or until the cheese is melted and bubbly.
