Step 1: Mix the seasoning - In a small bowl, combine the grated Parmesan cheese, smoked paprika, dried parsley, dried thyme, garlic powder, onion powder, black pepper, and salt. Stir until everything is evenly mixed. This seasoning blend is where all the flavor starts.
Step 2: Prepare the chicken - Using a sharp knife, gently score the tops of the chicken breasts in a grid pattern. You are not cutting all the way through. These shallow cuts help the seasoning soak in and allow the chicken to cook evenly.
Step 3: Coat the chicken - Press the chicken breasts into the Parmesan seasoning mixture, coating both sides. Use your hands to gently press it in so it sticks well. Do not rush this step. This coating is what creates that flavorful crust.
Step 4: Preheat the oven - Preheat your oven to 230°C or 450°F. Let it fully heat so the chicken starts cooking right away when it goes in.
Step 5: Prepare the baking dish - Drizzle the olive oil into the bottom of a baking dish and spread it around. Place the seasoned chicken breasts on top, leaving a little space between them.
Step 6: Bake the chicken - Bake the chicken for 20 minutes. During this time the seasoning will begin to crisp and the chicken will start cooking through.
Step 7: Make the garlic butter - While the chicken bakes, mix the softened butter with the finely chopped garlic and dried parsley until fully combined. This butter is what takes the dish from good to unforgettable.
Step 8: Add the garlic butter - Remove the chicken from the oven and brush the tops generously with the garlic butter. Sprinkle freshly grated Parmesan cheese over each piece.
Step 9: Finish baking - Return the chicken to the oven and bake for another 10 to 15 minutes until the chicken is fully cooked and the top is golden brown. The internal temperature should reach 165°F or 74°C.
Step 10: Rest and serve - Remove the chicken from the oven and let it rest for a few minutes before serving. This helps keep it juicy.
