Preheat the Oven:
Preheat your oven to 375°F (190°C). Lightly grease a baking dish or line it with parchment paper.
Prepare the Chicken:
Pat chicken dry with paper towels and season both sides with salt and black pepper.
Make the Creamy Topping:
In a small bowl, mix mayonnaise (or Greek yogurt), Parmesan cheese, garlic powder, and paprika until smooth.
Coat the Chicken:
Place chicken breasts in the baking dish and spread the creamy mixture evenly over each piece.
Bake:
Bake for 25–30 minutes, or until the chicken is fully cooked (internal temperature of 165°F / 74°C) and the top is golden brown.
Broil for a Crispy Finish (Optional):
Broil for 1–2 minutes for a slightly crisp, bubbly topping.
Serve:
Garnish with fresh parsley and serve warm with your favorite sides.
