Totally! You can go one of two routes here – you can either freeze the marinade on its own or freeze the marinade and pork tenderloin together. If you decide to freeze the marinade on its own, these mason jars will work great. When you're ready to use the marinade, just let it thaw completely (either overnight in the fridge or in a bowl of water for a quicker thaw) and then pour it over the pork and let marinate as normal. On the other hand, if you'd like to freeze the pork and marinade together, we recommend using a gallon size Ziplock bag and squeezing out as much air as possible before freezing. Be sure to label your bag with the date and contents so that your frozen pork tenderloin doesn't become a freezer mystery! When you're ready to cook the frozen pork tenderloin+ marinade duo, simply let it thaw completely and then cook using our perfect-every-time oven method!
