History

Teriyaki is a traditional Japanese cooking technique where foods are grilled or broiled with a glaze made from soy sauce, sugar, mirin, and sake. The word teriyaki comes from two Japanese words:

Teri = shine or glossy glaze
Yaki = grilled or cooked

Japanese immigrants later introduced teriyaki to Hawaii and North America, where it evolved into many fusion dishes. Chicken Teriyaki Casserole is one of these modern creations, combining classic teriyaki flavors with the convenience of an American-style baked casserole.
