- To store leftover buttermilk brined turkey breast, let it cool completely, then transfer it to an airtight container or wrap it tightly in foil or plastic wrap. Keep it in the refrigerator for up to 4 days.
- For longer storage, freeze the sliced turkey in a freezer-safe bag or container for up to 3 months.
- To reheat, gently warm it in the oven at 300ºF, covered with foil to retain moisture, or microwave individual portions until heated through.
