Absolutely! You can make the patties up to a day or two before you need them. Just make sure they aren't exposed to air, or they can dry out. I recommend placing plastic wrap between each layer, then covering the top with additional plastic wrap. You can either store them on a well wrapped plate, or in an airtight container. You can also form and freeze them. I like to flash freeze them on pieces of waxed paper, then stack them in ziplock bags. That way I can pull out what I need without them being completely stuck together.
