Preheat your oven to 425°F. Line a baking sheet with parchment paper and lightly brush it with olive oil. This prevents sticking and helps the chicken bottom get crispy instead of steamed. Pat your chicken breasts dry with paper towels—moisture is the enemy of crispiness. Season both sides generously with salt and pepper.

Set up your breading station with three shallow bowls: flour in the first, beaten eggs in the second, panko mixed with 1 tsp oregano in the third. Coat each chicken breast in flour first, shaking off excess. Then dip into the egg, letting it drip off slightly before rolling in the panko mixture.

Place breaded chicken on your prepared baking sheet. You'll hear it sizzle slightly when it hits the parchment—that's the signal your oven's hot enough. Drizzle a tiny bit of olive oil over the top of each piece. This helps the breadcrumbs brown evenly without being greasy.

Bake for 15-18 minutes until the chicken is cooked through and the breading turns golden brown. Don't panic if it looks pale at first—it'll brown quickly once the oven heat really kicks in. Mine always takes about 16 minutes, so set a timer and check at the 15-minute mark.

While the chicken bakes, warm your marinara sauce in a small saucepan over medium heat. Stir in the minced garlic and let it warm through. This step only takes 3-4 minutes and makes the sauce taste fresher and less like it came straight from a jar.

Remove the chicken from the oven carefully—it's hot! Top each piece with 2-3 tablespoons of marinara sauce, then sprinkle the mozzarella and parmesan cheese over top. When your kitchen smells like toasted garlic and melting cheese, you'll know it's almost ready. Return to the oven for 8-10 minutes until the cheese melts and gets slightly bubbly around the edges.

Let the chicken rest for 2-3 minutes after removing from the oven. This keeps the cheese from sliding right off. The residual heat finishes melting everything together while the breading sets up. Serve immediately while it's hot.
