Directions

1. Preheat oven to 450 degrees. In a 9×13 baking dish, toss around onion slices and olive oil. Add chicken to dish and sprinkle with salt, pepper and rosemary. Peek in on the chicken to make sure that the onions don’t burn up. In a small saucepan, bring the balsamic vinegar and garlic to a boil. Keep sauce boiling until it reduces into a nice thick, syrupy consistency. Turn off heat and set aside. When chicken is cooked, about 45 minutes later, scrape up all the onion bits from the bottom of the dish to loosen all the yummy bits and then pour over balsamic vinegar sauce over the chicken. Set dish to broil for 2-3 minutes or until bubbly. Serve with sauce heaped over chicken.
