Preheat the oven to 400°F (200°C) and lightly grease a 9x13-inch baking dish or spray it with olive oil spray.
In a bowl combine 1 cup panko, 1/4 cup grated Parmesan, and 1 teaspoon garlic salt; mix and set aside.
Melt 1/2 cup butter in a small bowl.
Working one breast at a time, dip a thin chicken breast into the melted butter to coat, then place it in the panko mixture (or a resealable bag) and press or shake to coat evenly.
Place the coated chicken breasts in the prepared baking dish, spacing them evenly. Lightly spray the tops with olive oil spray.
Bake the chicken for 25–30 minutes, until the internal temperature reaches 165°F (74°C) and the coating is golden.
While the chicken bakes, cook the orzo pasta according to package directions; keep warm.
When the chicken is cooked, spoon about 1/4 cup of Ragú sauce onto each breast, sprinkle about 1/4 cup shredded mozzarella over each, and add some basil to taste.
Return the dish to the oven and bake 4–6 minutes more, until the cheese is melted and bubbly.
Serve the baked chicken parmesan over warm orzo pasta.
