Refrigerate leftovers in an airtight container for about 3 days and reheat them in the preheated oven (350°F/180°C) for about 10 minutes or until heated through. They will not be very crispy anymore but will still taste great.  Use leftovers to make salads or sandwiches.  Almond-crusted chicken breasts are not great for freezing. Although technically possible, the coating doesn’t freeze well because it can become soggy and lose its crispiness once thawed.
