We had this for dinner tonight; it was the chicken that was served at my ward's Christmas party a few weeks ago. Its a sweet and moist chicken, very much like a mellow teriyaki chicken. Very good. My kids are not fans of bone-in chicken, but since it almost falls off the bone it wasn't hard to de-bone their chicken for them before serving it.
Christmas Party Chicken
2 - 2 1/2 lbs bone-in chicken thighs
1 cup lite soy sauce (you can use regular if you don't have lite)
2 cups brown sugar
Mix sugar and soy sauce until sugar dissolves. Pour into the bottom of a deep 9x13 pan (I have a stoneware 9x13 that worked) or a 11x17 pan - if you use a regular 9x13 pan there might be some boil over so put a cookie sheet under pan. Lay chicken on top of sauce and cover with foil. Cook for 3 hours at 300 degrees, flipping halfway through.
