Make marinade by mixing 1 tablespoons char siu sauce with 1 tbs soy sauce, 1 teaspoon oyster sauce, 1 teaspoon honey, ½ teaspoon sugar, ½ teaspoon salt, and 1 teaspoon mirin.
Pat fish dry with a paper towel and add marinade to both sides of the fish. If you want to make this quick, marinate the sea bass for 15-30 minutes before baking. If you have more time, I recommend to marinate overnight for a deeper flavor.
Top the fish with ½ tablespoon oil.
Preheat oven to 375 degrees Fahrenheit. Line baking pan with parchment paper. Add marinated sea bass on the parchment paper. Bake marinated fish for 10 minutes.
Take out fish from your oven and turn your oven to 475 degrees Fahrenheit or on 'broil' setting.
While the oven is heating up, brush honey on all sides of the sea bass. Then return to oven to bake at 475 for 3-5 more minutes or until golden at the top. This step is to brown the top and caramelize the honey!
When its done, plate the honey glazed chilean sea bass and pour 1 teaspoon soy sauce on top before eating! Enjoy while hot.
