How to store cooked sweet potato in the fridge?

Storing cooked sweet potatoes in the fridge is a great way to have a nutritious and convenient snack or side dish on hand. However, it’s important to store them properly to ensure that they stay fresh and safe to eat. Here are a few tips on how to store cooked sweet potato in the fridge:

  • Let the sweet potatoes cool down to room temperature before storing them in the fridge. This helps prevent condensation from forming inside the container, which can lead to spoilage.
  • Transfer the sweet potatoes to an airtight container or a resealable plastic bag. Make sure to remove as much air as possible to prevent oxidation. Alternatively, you can wrap them tightly in plastic wrap or aluminum foil.
  • Label the container or bag with the date so that you know when you cooked them. Cooked sweet potatoes can last up to 4 days in the fridge, so it’s important to keep track of when they were made.

If you’re storing a large batch of sweet potatoes, you may want to consider dividing them into smaller portions before putting them in the fridge. This will make it easier to grab a single serving when you need it. You can also freeze cooked sweet potatoes for longer storage, but the texture may change once they’re thawed.

Can cooked sweet potato be frozen?

If you have cooked sweet potatoes that you need to use later on, you might be wondering if it’s a good idea to freeze them. The answer is yes, you can freeze cooked sweet potatoes! Freezing cooked sweet potatoes is an excellent way of preserving these nutritious tubers and reducing food waste.

  • First, you need to cool your sweet potatoes properly before freezing them. The best way to do this is by spreading them out in a single layer on a baking sheet and placing them in the refrigerator for a few hours.
  • Once the sweet potatoes are cool, you can transfer them to an airtight freezer-safe container or a plastic freezer bag. Be sure to label the container with the date, so you know when it was frozen, and how long it has been in the freezer.
  • Frozen cooked sweet potatoes can last for around 6 to 8 months in the freezer. Keep in mind that the longer you keep them in the freezer, the more their texture and flavor might change.

If you plan to use frozen sweet potatoes in a stir-fry or mash, you can thaw them in the refrigerator overnight, or you can microwave them on defrost mode for a few minutes. However, if you are planning to use them as an ingredient in baked goods or casseroles, you can use them frozen without defrosting first, as they will cook along with the other ingredients in the recipe.

All in all, freezing cooked sweet potatoes is a smart and efficient way of preserving them and making sure that you always have a healthy and delicious ingredient on hand.
