Directions Sauté the garlic with oil in a small sauté pan until tender, turn off the heat and stir in the brown sugar. In a lightly greased casserole dish, place the chicken breasts and cover with the garlic and brown sugar mixture. Season with salt and pepper. In a preheated oven to 500° bake for 15 to 30 minutes and enjoy! Easy, peasy and sweet! I serve this chicken with some rice and veggie salad, it’s so good! When I cook this, I usually place a layer of tinfoil in the casserole dish and spray it with cooking spray so i can easy clean the casserole!
