Step 1: Preheat your ovenStart by preheating your oven to 375°F (190°C). This is the sweet spot that lets the chicken cook through without drying out, while still crisping up the creamy topping to golden perfection.

Step 2: Prep your baking dishGrab a 9×13-inch baking dish or any oven-safe dish large enough to hold your chicken breasts in a single layer. Give it a light spray or brush with oil to prevent sticking.

Step 3: Mix the creamy coatingIn a medium bowl, combine the mayonnaise, garlic powder, onion powder, salt, pepper, and Parmesan cheese. Stir until everything’s well blended. You’ll end up with a thick, creamy mixture that smells amazing already.

Step 4: Coat the chickenPlace the chicken breasts into the prepared baking dish. Use a spoon or spatula to spread the creamy mixture evenly over each piece of chicken. Make sure it’s coated fully from edge to edge. Don’t worry if it looks thick—it’s supposed to. This is what helps the chicken stay juicy and tender.

Step 5: Bake until golden and bubblyPop the dish into the oven and bake uncovered for about 35–40 minutes, depending on the thickness of your chicken breasts. You’re looking for an internal temperature of 165°F (74°C). The top should be golden and slightly bubbly, and the edges of the cheese will start to brown just a bit—that’s where the flavor magic happens.

Step 6: Let it restOnce it’s out of the oven, let the chicken rest for about 5 minutes before serving. This helps the juices redistribute so each bite is super tender.
