4 tablespoons unsalted butter, ¼ cup apple butter, 4 8-ounce boneless skinless chicken breasts, 1 large red onion, 2 small apples, 2 garlic cloves
Combine the white wine, chicken stock and apple cider. Pour over the chicken in the pan.
⅓ cup white wine, ⅓ Cup low sodium chicken stock or broth, ½ cup apple cider
Season with salt, black pepper, Italian seasoning and rosemary sprigs. Toss to combine.

Place in the preheated oven and bake for 20-25 minutes or until the internal temperature of the chicken reaches 165 degrees.
Turn the broiler on in the oven. Broil for 3 minutes watching it closely or until the chicken is golden brown. NOTE: monitor closely to avoid burning.
Remove from oven and let rest three minutes for the juices in the chicken to redistribute before cutting and serving.
