Empanadas are a great meal for meal prepping. You can mix up the dough and the filling several days in advance. You can also stuff the dough and wait to cook them later or even cook them completely and enjoy them over the course of several days. They make delicious leftovers. Store any uncooked dough or filling in an airtight container in the refrigerator until you are ready to cook. If you decide to pre-stuff your dough, simply line a baking sheet with parchment paper and place the stuffed, uncooked empanadas on the baking sheet. Make sure to cover them! Keep them in the refrigerator until you are ready to cook, up to 48 hours later. If you would like to freeze your empanadas, you can stuff the uncooked dough, place them on a lined baking sheet and put them in the freezer. Once frozen, transfer them to a ziploc. Thaw them in the fridge overnight in a single layer before cooking.
