Yes, you can. But first, know that a frozen and reheated egg and sausage biscuit will have a different texture than when it is fresh and the egg won’t be as soft. But we have certainly done it and we will do it again for our own quick breakfasts. We wouldn’t do it if we were trying to roll out the red carpet for guests :). If you’d like to give it a try, place them in an airtight container in the freezer. Let them thaw completely in the refrigerator and reheat them by wrapping them in a paper towel and warming them in the microwave in 30-second increments until warmed through.
