Cook Chicken: Toss cut chicken breasts with olive oil and poultry seasoning. Heat a large skillet over medium heat and cook the chicken for 5 to 7 minutes until golden brown and cooked through. Remove and set aside.

Prep Bread: Preheat oven to 350°F (175°C). In a bowl, mix melted butter, minced garlic, parsley, and crushed red pepper flakes. Slice the loaf in half lengthwise and spread the garlic mixture on both halves. Toast in the oven for 5 to 10 minutes.

Make Alfredo Sauce: In the same skillet, melt remaining butter over medium-low heat, add minced garlic and sauté. Pour in heavy cream, sprinkle with Parmesan cheese, and stir for 3 to 5 minutes until thickened.

Assemble: Spread half of the Alfredo sauce on the toasted garlic bread. Layer cooked chicken evenly, add mozzarella cheese, and drizzle with remaining sauce.

Bake: Return to the oven and bake for about 5 minutes, until cheese is melted and bubbly.

Serve Warm: Slice into portions and serve warm, optionally with a side salad or marinara sauce for dipping.
