Preheat your oven to 400°F.
In a small bowl, mix together garlic powder, onion powder, paprika, salt, and black pepper.
Pat the chicken breasts dry with paper towels and rub the spice mixture evenly over both sides of the chicken.
In a large oven-safe skillet, heat olive oil over medium-high heat. Once hot, add the seasoned chicken breasts and sear for 4-5 minutes on each side until golden brown.
Remove the skillet from heat and drizzle the Caesar dressing over the chicken, ensuring it is well-coated.
Sprinkle the grated Parmesan cheese on top of the chicken.
Transfer the skillet to the preheated oven and bake for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F.
Remove from the oven and let the chicken rest for 5 minutes before slicing. Garnish with chopped parsley before serving.
