How to Defrost Uncrustables

What are the best ways to defrost your Smuckers Uncrustables? Is it to use body heat, warm water, a heating pad? No, it’s even easier than that.

Best way. The best way to thaw your frozen Uncrustable sandwich is to transfer them from the freezer to the refrigerator overnight and allow them to safely defrost for about 6-8 hours, leaving them sealed in their store packaging.

Room temperature. To thaw them on the kitchen counter, place them on a paper towel for up 1-2 hours until they’re thawed. Please be advised, it could take as little as 30-60 minutes for them to thaw, depending on the room temperature.

Lunchbox. When packing them for lunch, you can allow them to thaw in transport by packing them with a cooler ice block and likely they’ll be defrosted by lunchtime and ready to enjoy.

How to Store Uncrustables

The shelf life of Uncrustables and maximum freshness is determined by proper storage. Our recommended storage instructions will also help you maintain the best taste possible.

Airtight Container. After your crustless sandwiches have been unwrapped from the commercial packaging, if you don’t intend to eat them right away, you can store them in an airtight container.

This will help to maintain the right conditions that will provide a longer shelf life.

Freezer-Safe Bag. If your sandwich is still frozen but has been removed from the commercial plastic wrap, you might opt to put it back in the freezer.

Using a freezer safe bag and sealing the sandwich inside is one of the best options for a long shelf life when storing under cool temperatures.

Food Safety

Regardless of the food item that’s being considered, if food sit out for a long time, it grows unwanted bacteria which can make people very sick.

The same is true with thawed Uncrustables. If you suspect your food has gone bad, never risk eating it. Throw it away instead.

How Long Can Uncrustables Safely Sit Out?

The time frame that your crustless sandwiches can sit out depends on their current state. According to the Smucker’s website, here is the information about refrigerating them.

“For best product experience, we do not recommend refrigerating Uncrustables as it may dry out the bread. If you choose to refrigerate the sandwiches, they should be eaten within 1 day or 24 hours for best taste. Uncrustables crustless sandwiches should be eaten within 6-8 hours of thawing.”

How To Know if Your Uncrustables Have Gone Bad

A sure sign that your crustless sandwiches have gone bad is if they’ve sat out for too long. If they’ve sat at room temperature for more than 2 hours, chances are they’ve become a breeding ground for unwanted bacteria.

Some other key indicators of spoilage include:

Expiration Date. Check the expiration date of the product to see how close the date is.

Since this is a freezer product, it would likely be safe to eat it a few days after the expiration date has passed, as long as no other key indicators of spoilage are present.

Ice Crystals. Ice crystals tend to indicate spoilage as well.

Usually, frozen foods that have formed significant ice crystals also possess a freezer burned flavor and you’ll want to throw them away. 

Unpleasant Odors. As is the case with defrosted Uncrustables, they can become a breeding ground for unwanted bacteria.

This can cause the growth of mold, or sometimes just an unpleasant odor. If you notice a strange smell, just throw your sandwich away instead of eating it.

Risks of Eating Food That Has Gone Bad

The risks of eating food that has gone bad is the potential for food poisoning which can result in serious illness and sometimes leads to death.

If you have food products that have experienced improper storage or have sat out for a significant amount of time, throw them away. Do not risk eating it!

A Note About Using a Sandwich Sealer. You might choose to use a sandwich sealer if you have one on hand, but you don’t need to go out and buy one specifically for this.

You can simply use a large cup or cookie cutter to cut the shape of the sandwich, and then use a fork to seal the edges, instead of using a sandwich sealer.


Place two slices of bread on a hard surface. You can use either white bread, whole grain bread, gluten free bread, or any favorite bread.

If you’re making a meat and cheese sandwich, you can place those between the two slices of bread now.

If you’re using a spread such as peanut butter and jelly, you can add those after the bread has been cut.

Then use your sandwich sealer, round cookie cutter, or a large cup and press down firmly to cut through all the layers.

Discard the excess bread or eat it separately. You’re now ready to seal the edges of your sandwich. You can seal them by using your sandwich sealer or by using the tongs of a fork to press and seal all the way around the edges.

Enjoy your homemade Uncrustable as the perfect snack!

Other Ways to Prepare Uncrustables

Eating Smuckers Uncrustables Sandwiches straight from the packaging is not the only way to eat them. You might be wondering about other ways they can be prepared. Using an air fryer is a popular way to brown and serve them. It’s the best place to toast them if you like a crispy outside.

Air Fryer Uncrustables. To prepare your little crustless sandwiches in an air fryer, remove the packaging and brush the tops with butter to help them brown and for the best results.

Place them directly in the air fryer basket and be sure to leave a little space between each one.

Then, set your air fryer to 350F degrees and cook the sandwich for 6 to 8 minutes.

Serve warm and enjoy!

Do Not Microwave. We don’t recommend microwaving Uncrustables because it makes them too soggy and not as delicious of an outcome.
