Storage & ReheatingWrap individually in foil or parchment and store in the fridge for up to 3 days. Freeze tightly wrapped in foil for up to 1 month. Thaw overnight in the fridge before reheating. Air fry at 180°C (350°F) for 4-5 minutes until the bun is toasted and the cheese is melted. Avoid microwaving — the bun will go soft and lose its texture.
