Preheat your oven to 400°F (200°C).
Pat the chicken breasts dry and season both sides with garlic powder, paprika, salt, and pepper. Brush with olive oil.
Heat a large oven-safe skillet over medium heat. Sear the chicken breasts for 2–3 minutes per side until golden brown.
Transfer the skillet to the oven and bake for 15–20 minutes, or until the internal temperature of the chicken reaches 165°F (74°C).
In a small bowl, combine panko breadcrumbs, grated Parmesan cheese, melted butter, and Italian seasoning to create the Parmesan crust mixture.
Remove the chicken from the oven and spread the Parmesan crust evenly over each piece. Return the skillet to the oven and broil on high for 2–3 minutes, or until the crust is golden and crispy.
In another small bowl, mix ranch dressing, grated Parmesan cheese, and mayonnaise to make the Parmesan ranch sauce.
Drizzle the sauce over the cooked chicken and serve immediately with your favorite sides.
