How To Freeze Sweet Potatoes (Baked, Mashed, Boiled & Fried)

Sweet potatoes are incredibly versatile, and they can add something to any meal, whether you want to nibble on some fries or cook up some soup. However, it’s easy to get carried away and make too much, which begs the question – can you freeze sweet potatoes?

You can freeze sweet potatoes to extend their shelf life for 12 months. However, prep them beforehand to prevent freezer burn and keep them from getting mushy once thawed. To maintain the texture when reheated, you can bake, mash, or fry sweet potatoes before freezing. 

In this article, I’ll teach you how to prepare and freeze your sweet potatoes so you can keep these tubers in stock all year round. Now, you can simply reheat your frozen sweet potatoes, and after a few minutes, enjoy them as if you just bought a fresh batch from the market!

How To Freeze Sweet Potatoes (Baked, Mashed, Boiled & Fried)

How To Freeze Sweet Potatoes

Sweet potatoes are cheap yet nutritious and delicious. Plus, you can do so many things with them–fry, blanch, bake, boil, mash, wedge–you name it! If you don’t want to keep going to the market to buy yourself a bunch, you can simply store them in your freezer for months and keep them ready for a quick reheat.

However, proper preparation before freezing is essential to maintaining that nice crisp texture once you warm your sweet potatoes up again. When storing sweet potatoes, a general rule is never to freeze them raw. That is because sweet potatoes, sometimes called yams, have a very high water content.

When they are frozen raw, the water inside the potatoes will crystallize and completely change the structure of the sweet potatoes. As the moisture inside the potatoes freezes, it bursts some of the veggie’s cells, resulting in mushiness. Once they thaw, they will lose their firm texture and become watery and grainy instead. 

The taste will also change since the cell structure has changed after freezing your sweet potatoes.

Your thawed sweet potatoes may taste bland, losing that unique earthy sweetness that we love about them. Also, they may even turn dark when you try to cook them after thawing. Talk about unappealing, right? 

So if you’re planning to store your sweet potatoes, make sure you’ve prepped them properly beforehand. Here are the three of the best ways to freeze sweet potatoes:
