Cooked beef empanadas can be refrigerated for up to 3 days or frozen for up to 2 months. You can also prepare your empanadas but do not bake them. Instead freeze your empanadas unbaked in a single layer in a covered container. then when you are ready to eat. Preheat the oven to 350 degrees F (176 degrees C) and bake for approximately 20 - 25 minutes or until crust is golden brown. As they are frozen, they take a little longer to bake.
