Mozzarella has fully melted into glossy pools with the first hint of browning at the edges; marinara is bubbling actively around the perimeter of the pan; chicken reads 165°F on a Thermapen; no pink or opaque-uncooked spots visible where the cheese has parted. Confirm internal temperature reaches 165°F (74°C) — USDA FSIS chicken minimum, checked at the thickest part of the breast before topping with cheese. Rest for 5 minutes before serving.
