This is the best garlic chicken I have ever tried. Due to tight schedule, I couldn't get all the ingredients in hand, I use premixed spice (celery salt) in replace of missing ingredient celery stalks. I was generous when come to using garlic. I had thrown in 30 bulbs of garlic to roast two chicken legs! As I opened the casserole, the aroma is incredible. The chicken is utterly infused with the smell of garlic and herb. To ease my workload, I used garlic peeler to strip off garlic skins before adding into the chicken. If you wish to reducing the sauce in oven, corn flour mixture (1 tbsp. corn flour w/ 3 tbsp. water) can be added at the last 5 minutes and let it sit in the oven for extra 5-10 minutes).
