Prep the oven and pan: Preheat the oven to 425°F (220°C). Line a sheet pan with parchment and lightly spray or brush with oil.
This helps the coating crisp instead of steam.
Pound the chicken: Place chicken breasts between two sheets of parchment or plastic. Gently pound to an even 1/2-inch thickness so they cook evenly and stay juicy.
Season the breadcrumb mix: In a shallow bowl, combine panko, Parmesan, garlic powder, onion powder, oregano, basil, salt, and pepper. Stir well.
Beat the eggs: In another shallow bowl, whisk the eggs with 2 teaspoons of water.
If you prefer ultra-light breading, use just egg whites.
Bread the chicken: Dip each piece into the egg, let excess drip, then press firmly into the breadcrumb mixture to coat both sides. For extra crunch, drizzle or mist the tops with a touch of olive oil.
Bake to golden: Arrange on the pan and bake for 12–15 minutes, flipping once halfway. Chicken should be nearly cooked through and breadcrumbs lightly golden.
Layer with sauce and cheese: Transfer chicken to a lightly oiled baking dish.
Spoon marinara around and over the chicken—don’t drown it; leave some edges exposed to keep things crisp. Top with mozzarella and a sprinkle of extra Parmesan.
Bake again: Return to the oven for 8–10 minutes, until the cheese melts and the sauce is bubbly. If you like browned spots, broil for 1–2 minutes at the end.
Watch closely.
Rest and garnish: Let sit 5 minutes so juices settle. Finish with fresh basil. Taste and add a pinch of salt if needed.
Serve smart: Pair with roasted veggies, zucchini noodles, a simple green salad, or whole-wheat spaghetti for fiber.
