“I cook rarely, but I’ve kind of got two or three dishes that I stick to. I do a great sweet potato and a lentil curry” – Chris O’Dowd

Unlike Chris O’ Dowd, I cook all the time. However, I still rely heavily on sweet potatoes, because they taste great, cook very fast, and are very nutritious.

Let’s take a look at why great-tasting sweet potatoes should be an essential part of your diet.

  1. Sweet potatoes contribute to your gut health by preventing constipation, helping to absorb water, and keeping the lining of your intestines healthy.
  2. Just like carrots, sweet potatoes are great for the eyes, thanks to the presence of beta-carotene which the body converts into Vitamin A. This particular vitamin is known to improve the receptors in your eyes.
  3. Beyond Vitamin A, sweet potatoes are a super-food that contains almost all of the nutrients your body needs. One sweet potato contains 112 calories, 0.07 grams of fat, 26 grams of carbohydrates, 2 grams of protein, and 3.9 grams of fiber.
  4. Sweet potatoes can help manage stress and improve your mood. Lack of magnesium can be a risk for anxiety, stress, and depression. With sweet potatoes, you get one-third of your daily magnesium dose.
  5. Carotenoids found in sweet potatoes keep your cells protected from the damage of day-to-day activities. (Source: Allrecipes.com, webmd.com)

I could go on and on about the benefits of sweet potatoes. Honestly, what is there not to love? They are healthy, they taste great, and are super convenient to incorporate into your diet.

These sweet roots are available year-round, but you’ll find them plentiful from August through November. However, you may have a few extra sweet potatoes that you’re not sure what to do with.

You might ask yourself, Can You Freeze Sweet Potatoes? The answer is yes, you can freeze sweet potatoes for up to 12 months. However, freezing sweet potatoes comes with a process.

I’ll be discussing the details of how to freeze sweet potatoes extensively in this piece, the processes, what to do for best results, and what to avoid. Let’s delve in together.

Can You Freeze Sweet Potatoes Raw?

No, you cannot freeze raw sweet potatoes, they need to be blanched before freezing

No, you cannot freeze sweet potatoes raw. They need to be blanch before freezing or you run the risk that they become mushy and lose flavour upon thawing.

Just like with apples, sweet potatoes will change color after a few minutes of cutting through them. This happens when you cut potatoes because the enzyme polyphenol oxidase gets exposed to oxygen. Exposure to oxygen converts the phenolic compounds in the enzyme to o-quinones. The o-quinones react with amino acids present in the potatoes to produce the brown colors you see on cut potatoes.

Hence, we need to blanch raw sweet potatoes before freezing them to reduce the enzymes that will cause the sweet potatoes to change texture, flavor, and color over time.

Blanching is a process that helps to preserve the flavor, texture, color, and nutritional value of foods. This is especially true with vegetables. Blanching is the process of immersing food in boiling water briefly (not more than a few minutes, two minutes maximum), which is then put in an ice-water bath to cool the food off quickly.

According to the National Center for Home Food Preservation, it is important to blanch vegetables before freezing them. This puts a stop to the enzymatic activities and gets rid of surface organisms and dirt. Sweet potato is a vegetable, and it is a sweet-tasting large root that belongs to the morning glory family.

On the other hand, whether cooked or pre-cooked, frozen sweet potatoes will last for about 10-12 months in the freezer.

Food stored in the freezer will maintain the best quality throughout the storage period. If after defrosting, your potatoes have a foul smell or look off in their appearance, discard them immediately.

Defrosting sweet potatoes comes with several options. Some of the options will work for pre-cooked and cooked sweet potatoes while others are best suited for cooked sweet potatoes. Let’s look at the options in detail.

  • Refrigerator
  • Oven
  • Microwave
  • Incorporate directly

To defrost frozen sweet potatoes using the refrigerator, take out the sweet potatoes from the freezer and transfer them to the fridge. Leave in the refrigerator overnight so the sweet potatoes can defrost slowly.

Cooked sweet potatoes that have been thawed using the refrigerator can be stored there for about 3 – 4 days before cooking.

Defrosting frozen sweet potatoes by baking or roasting in the oven is an excellent option for frozen baked sweet potatoes. Bring out the frozen sweet potatoes from the freezer, and remove the foil used to wrap each piece. Wrap them with a new foil and bake for up to twenty-five minutes with the oven set to 350°F (180°C).

Defrosting frozen sweet potatoes with the microwave is a straightforward process. Take out the frozen sweet potatoes from the freezer, put them in a microwave-safe bowl, and set the microwave to the defrost setting. The microwave method may leave your sweet potatoes a little dry.

Frozen sweet potatoes defrosted with the microwave should be eaten immediately, or you may run the risk of food poisoning. The microwave brings food to optimal temperature for bacteria to grow in large quantities over a short period of time.

The last method of defrosting is to add the frozen sweet potatoes directly into your stovetop recipes. Add a few minutes to the total cook time to make up for the temperature drop when you add the frozen sweet potatoes directly into your cooking.
