Prep the oven and pan: Preheat your oven to 400°F (200°C). Lightly grease a 9x13-inch baking dish or line it with parchment for easy cleanup.
Flatten the chicken: If the breasts are thick, place them between sheets of plastic wrap and pound to an even 3/4-inch thickness.
This helps them cook evenly and stay juicy.
Season well: Pat the chicken dry. Rub both sides with olive oil, then sprinkle with salt, pepper, garlic powder, onion powder, and Italian seasoning. Lay the chicken in a single layer in the baking dish.
Add the sauce: Spoon the pizza sauce evenly over each breast.
Don’t drown them; you want a coating that clings without pooling.
Cheese layer: Sprinkle mozzarella over the sauced chicken, then dust with Parmesan for extra savory flavor.
Top it like pizza: Add pepperoni, bell pepper, red onion, and olives. Distribute toppings so each piece gets a bit of everything.
Bake: Place the dish in the oven and bake for 18–22 minutes, or until the chicken reaches an internal temperature of 165°F (74°C). If your chicken is thicker, add a few more minutes.
Optional broil: For a golden, bubbly top, switch to broil for 1–2 minutes at the end.
Watch closely to avoid burning.
Rest and garnish: Let the chicken rest for 5 minutes so the juices settle. Sprinkle with fresh basil or parsley if you like.
Serve: Pair with a side salad, roasted veggies, or steamed greens for a balanced meal.
