In a saucepan, combine tomato sauce, minced garlic, Italian seasoning, olive oil, salt, and pepper. Bring to a gentle simmer over low heat to meld flavors without burning, stirring occasionally for approximately 10 minutes.

Heat a skillet over medium-high heat with olive oil. Sear chicken breasts until golden brown and Maillard crust forms, approximately 2-3 minutes per side. Remove and set aside.

In a baking dish, spread a thin layer of simmered tomato sauce. Layer browned chicken pieces evenly, then cover with the remaining sauce. Sprinkle mozzarella and Parmesan cheese evenly over the top.

Bake in a preheated oven at 180°C for 25 minutes. Halfway through, uncover and check for caramelization and bubbling sauce. If edges are browning too quickly, tent dish with foil. For extra crust, broil for 1-2 minutes watching carefully.

Verify chicken is fully cooked by ensuring juices run clear when pierced at the thickest part. If not, bake for an additional 5 minutes. Remove from oven and allow to rest for 10 minutes to let juices redistribute.
