You can store assembled Garlic Bread Toast (before air frying) in the fridge for up to one or two days, or freeze it for longer storage. Leftover garlic butter can be used in any savory recipe that calls for butter; I like to use it for making French Loaf Vada Pav. Once air-fried, leftovers can be stored in the fridge for 2-3 days or frozen. To reheat, simply thaw and air fry for 2-3 minutes at 375°F. You can also cut leftovers into cubes and use them as croutons for salads or soups.
