Bake at 350° F (177° C) on a foil-lined baking tray. Place marinated Char Siu Pork on the baking racks (saving the marinade), then bake for 30 minutes.
Remove pork from oven, baste with char siu sauce, then bake for another 15 minutes. Repeat 2 more times so the Char Siu Pork turns out caramelized outside & SUPER juicy inside.
