Do Uncrustables Need to Be Refrigerated?

Uncrustables are one of the most popular sandwich products. They come in a variety of shapes and sizes, including tubes, swirly rolls, and even a pre-made sandwich line. But do they need refrigerating?

Yes. If you don’t plan on eating them for a while after buying them, then you should definitely refrigerate them. This is because if left at room temperature, particularly if it’s warm, Uncrustables will rot or spoil in just a few hours.

Generally, the cooler the temperature the longer they can go without getting spoiled. So, by refrigerating them, you can ensure that they stay unspoiled for days, possibly even weeks if the product was fresh. They also need to be refrigerated after thawing. You can refrigerate them for up to 24 hours after they have been thawed.

What Is the “Uncrustable” Process?

  1. Slice off the crusts.
  2. Stuff with lunch meat, cheese, or other fillings.
  3. Wrap up in a special wrapper. This process is what allows you to eat Uncrustables at room temperature without having them get soggy or gross as regular bread would.
  4. If you don’t plan on eating them for a while after buying them, then you should definitely refrigerate them. This is because if left at room temperature, particularly if it’s warm, Uncrustables will rot or spoil in just a few hours. So if you plan on keeping them longer than that, it’s best to put them in the refrigerator so they will last longer and taste better.
  5. Eat! When ready to eat your Uncrustable sandwich, take it out of the refrigerator and wait until it’s been at room temperature for about 30-60 minutes.

How Long Can Uncrustables Be Left Out for?

Uncrustables shouldn’t be left out for more than a few hours. Depending on the room temperature, they will begin to spoil or rot very quickly. To thaw them, it is recommended that you leave them out at room temperature for about 30-60 minutes.

After thawing, you should eat them within about 6-8 hours for best taste, that is if they were unrefrigerated. Refrigerated Uncrustables should be eaten within 24-hours of thawing.


Do Smuckers Have to Be Refrigerated?

Uncrustables sandwich fillings are shelf-stable, meaning that they do not require refrigeration. This is because the filling contains no dairy products, which can spoil in non-refrigerated conditions. Smuckers also use preservatives in the bread, which extends its shelf life.

While it’s not really necessary to refrigerate Smuckers, it is still recommended. According to the manufacturer, their unopened products have a good shelf life. This means you can store them at room temperature in the cupboard or pantry and they will remain safe to eat.

However, their color and flavor will decline over time. So, it’s best to refrigerate them to preserve their taste. Even then, it’s recommended that you consume them within the period of time specified by the manufacturer.


How Do You Defrost Uncrustables?

Uncrustables don’t have crust present in the food and they have jam in them. Because of this, the manufacturer strongly forbids using a microwave to defrost them because it makes them worse.

Ideally, the best way to defrost them is to leave them at room temperature for 30-60 minutes. If you are in a rush, you can accelerate the process by putting the Uncrustables in your two hands and allowing your body heat to thaw them out.

Some consumers also use an air fryer to defrost Uncrustables. To do this, simply wrap and put a frosted sandwich in the air fryer for about 5-10 minutes. Make sure that the air fryer operates at no higher than 400°F.


How Are Uncrustables So Good?

Uncrustables have several qualities that make them a better alternative to their traditional counterpart. They are similar to the classic peanut butter and jelly sandwich but they are not messy. They are also a low-fat version of their traditional counterpart which makes them ideal for people with dietary restrictions.

Apart from this, they also contain a decent amount of fiber which has many health benefits. Uncrustables are high in protein as they are made with whole grains. Overall, they are a good option for healthy snacking that packs good nutrition.

But keep in mind that they are pretty high in sodium and calories, so it is recommended that you only eat them occasionally. If you are not allergic to nuts and you want to try them out, know that it’s fine to eat one every once in a while. Just make sure it doesn’t turn into a habit.


In summary, the biggest thing to watch out for with Uncrustables is the date. Uncrustables have a “best by” date stamped on the bottom. This date signifies when the product should be used by. The Uncrustable will be best if it is eaten before this date, but you can also use it after this date as long as you follow proper food safety guidelines.

Uncrustables should be kept away from heat sources and direct sunlight at all times because these are two of the main causes of food spoilage. Once opened, they should be refrigerated until they are consumed.
