Place chicken breasts on a cutting board. Slice them carefully into thinner pieces. Use a meat mallet to flatten them evenly. This helps them cook faster and stay tender inside.

Sprinkle salt, black pepper and garlic powder on both sides. Rub gently so the flavor sticks well. Let the chicken rest for a few minutes before coating.

Prepare three bowls with flour, beaten eggs and breadcrumbs mixed with parmesan. First dip chicken in flour. Then dip in egg. Finally coat with breadcrumbs evenly for a crispy layer.

Heat olive oil in a pan over medium heat. Fry chicken pieces until golden brown on both sides. Do not overcook. The chicken will finish cooking in the oven later.

Spread a thin layer of tomato sauce in a baking dish. This helps keep the chicken moist and flavorful during baking. It also prevents sticking at the bottom.

Place fried chicken pieces in the baking dish. Spoon more tomato sauce over each piece. Add mozzarella cheese on top. Make sure every piece is well covered.

Preheat oven to 180°C. Bake the chicken for about 15 to 20 minutes. The cheese should melt fully and become slightly golden and bubbly on top.

Remove from oven carefully. Garnish with fresh basil leaves. Let it rest for a few minutes before serving. This helps flavors settle and makes it even tastier.
