Yes! It’s a fantastic opportunity for meal prep. It pretty much takes the same amount of time to prepare two or three acorn squash as it does to cook one. Simply allow the stuffed squash to cool, then use a freezer safe container or freezer bag to store in the freezer for 2-3 months. To reheat, simply thaw in the refrigerator overnight, then heat in a 325º F oven for 20-25 minutes.
