Question: I’d like to cook my mashed potatoes in advance, because I have so much cooking to do on Thanksgiving! Is freezing a viable option?
Answer: Yes, it’s very possible to freeze mashed potatoes for later use. In fact, you can preserve them for a few weeks in advance of your upcoming meal. Unfortunately, you run the real risk of compromising the texture of the potatoes, but there are a few ways you can avoid this and maintain the quality of your food. One way there is plenty of whole milk and butter mixed in your potatoes before you freeze them. Make sure you use whole milk, because it will better preserve the taste and texture of your potatoes. Some potatoes are better suited to freezing, while others, such as russet potatoes, are starchier and don’t freeze as well. You may have to do a little research and compromise if there is a certain type of potato you want to serve.
To begin the process, peel your potatoes and mash them, using plenty of milk and butter. Then, take your baking sheet and line it with parchment paper. At this point,k you may wish to use an ice cream scooper to place your mashed potatoes on the baking sheet. Place them in the freezer and leave them in there for two hours, or until they have frozen solid. When they’re ready, you can remove them from the tray and place them in a ziploc bag. Make sure to squeeze as much air as you can out of the bag prior to sealing it. Also, don’t forget to mark the date on the bag with a permanent marker so you can easily remember how long it’s been in your freezer. Experts say that you can keep mashed potatoes frozen for up to two months by utilizing this technique, but you may have better results if you remove them sooner.
To fully thaw your mashed potatoes, put them in your refrigerator for eight hours. Then, you can remove the potatoes and place them in a covered bowl. Reheat them in your microwave at 50 percent power, for close to five minutes, or until they are thoroughly heated. Make sure that they are well-heated in the center, and you can test this by dipping a spoon into the center and tasting it. After they heated, stir them. You may find that the potatoes are too watery, and if this is the case, stir in a tablespoon of cream cheese to thicken them.
