I used 40 cloves of freshly peeled garlic, and the chicken was still somewhat bland. Cooking it in the covered skillet gave it a tougher consistency that was a little hard to eat.
I used 20 cloves, about half the chicken, and jack daniels to make this a little different. I also finished it in the oven at 400 degrees for about 25 minutes. Turned out really fantastic with the sauce. Served over some potato gnocchi and it's a great meal!
