# What You'll Need:
→ Bread Base
01 - 1 loaf Italian bread, sliced lengthwise
02 - ½ cup (1 stick) unsalted butter, softened
03 - 1 teaspoon garlic salt
→ Chicken
04 - 2 boneless skinless chicken breasts (about 1 pound), cut into ½-inch pieces
05 - ½ teaspoon garlic salt
06 - ½ teaspoon paprika
07 - ½ teaspoon kosher salt
08 - ¼ teaspoon black pepper
09 - 1 tablespoon extra virgin olive oil
→ Alfredo Sauce
10 - 2 tablespoons unsalted butter
11 - 1 small yellow onion, diced (about ½ cup)
12 - 2 teaspoons garlic, minced
13 - 2 cups heavy whipping cream
14 - 2 cups Parmesan cheese, finely grated
15 - ½ teaspoon kosher salt
16 - ½ teaspoon black pepper
17 - ¼ teaspoon crushed red pepper flakes
→ Topping
18 - 1 cup mozzarella cheese, shredded
19 - 1 cup white cheddar cheese, shredded
20 - Fresh parsley, chopped for garnish
# Directions:
01 - Preheat oven to 400°F. Line a large baking sheet with parchment paper.
02 - Place Italian bread halves cut side up on prepared baking sheet. Spread softened butter evenly over both halves and sprinkle with garlic salt.
03 - Bake bread for 8–10 minutes until lightly golden and crisp. Remove from oven and set aside.
04 - While bread bakes, season chicken pieces with garlic salt, paprika, kosher salt, and black pepper.
05 - Heat olive oil in a large skillet over medium-high heat. Add chicken and cook 3–4 minutes per side until golden brown and cooked through (internal temperature 165°F). Transfer to a plate and keep warm.
06 - For the Alfredo sauce, melt butter in a saucepan over medium heat. Add diced onion and cook 3–4 minutes until translucent. Stir in garlic and cook 30 seconds.
07 - Pour in heavy cream and bring to a gentle simmer. Stir in Parmesan, salt, black pepper, and red pepper flakes. Continue stirring until cheese melts and sauce thickens slightly, about 3–5 minutes. Remove from heat.
08 - Spread about ¾ cup of Alfredo sauce over each toasted bread half, reserving about ½ cup for serving. Top with cooked chicken, distributing evenly. Sprinkle with mozzarella and white cheddar cheese.
09 - Return bread to oven and bake 8–10 minutes until cheese is melted and bubbly. For a golden top, broil 1–2 minutes watching closely.
10 - Remove from oven and let rest 2–3 minutes. Garnish with chopped parsley. Slice and serve warm with reserved Alfredo sauce on the side for dipping.
