1-First, preheat the oven to 450 degrees F. This high heat helps achieve that perfect golden crust without overcooking the chicken.

2-Next, butterfly the chicken breasts by slicing them horizontally to create thin, even halves, then pat dry and season with salt and pepper. This step ensures the chicken cooks evenly and absorbs flavors well.

3-Then, beat the eggs in a shallow bowl. In another bowl, combine the breadcrumbs, half of the Parmesan cheese, and garlic powder, creating a tasty coating mixture.

4-After that, dip each chicken piece into the egg mixture, then coat with the breadcrumb mixture, pressing crumbs to adhere for a crunchy finish.

5-Now, heat olive oil in a large skillet over medium-high heat and brown the chicken for about 2 minutes per side until golden but not fully cooked. This browning step locks in juices and adds extra texture.

6-Spread a thin layer of marinara sauce in a 9×13 inch baking dish, place the browned chicken on top, spoon more marinara sauce over the chicken, and sprinkle with mozzarella and remaining Parmesan cheese.

7-Finally, bake for 10-15 minutes or until the cheese is melted, bubbly, and the chicken reaches an internal temperature of 165 degrees F. Garnish with fresh chopped basil and serve over cooked spaghetti with extra marinara sauce if desired.
