Yes, this chicken dish freezes well. Remove the cooked lemon slices before freezing, then cover the dish or transfer to an airtight baking dish and freeze. Thaw it in the refrigerator overnight, add fresh lemon slices, then reheat it covered, at 350°F. for about 30 minutes or until heated through. You may want to place it under the broiler for a minute or two to crisp the skin.
