Wrap leftovers tightly in foil or plastic wrap to keep that tender pull of the biscuits intact. Store in the fridge for up to 3 days. You can also pop the leftovers into an airtight container if you wanna save space and prevent fridge odors. For freezing, put biscuit halves in a freezer bag or container. Just remember to thaw overnight in the fridge before reheating so the seafood mixture doesn’t dry out.
