This turkey breast is best cooked and served as soon as it's ready, but you can brine it overnight and season and wrap it a few hours ahead of time and keep it covered in the fridge til you are ready to cook it. Any leftovers will keep well in the fridge for up to 4 days. They can be enjoyed cold in sandwiches or salads, or chopped up and added into soups and stews. You can also reheat the turkey breast in the air fryer or oven.
