In this brief guide, we will answer the question, how long can you keep Uncrustables in the fridge? We will discuss how to store and safely consume Uncrustables. We will discuss the nutritional profile and how to make Uncrustables at home. 

How long can you keep Uncrustables in the fridge?

You can keep Uncrustables in the fridge for about 2 days. Uncrustables are stored in the freezer and then thawed at room temperature when you want to eat them.

When you thaw Uncrustables on the counter instead of the fridge, they should be eaten within 6-8 hours. For best taste, eat the Uncrustable within 24 hours instead of keeping it for 2 days. 

Uncrustables should be eaten within two hours. For on-the-go picnics and lunches use ice packs to make them last for 6 hours.

When stored in the freezer, the Uncrustables will keep for a month. Homemade Uncrustable sandwiches will last for longer than a month in the freezer. 

Uncrustables should not be stored at room temperature for more than 2 hours. According to the FDA, food that has been kept at 90 Fahrenheit or higher for an hour has become unfit for consumption.

You can not refreeze Uncrustables. Refreezing will cause the thawed ice crystals to cause the bread to become soggy. 

Check the package for the expiration date. Watch out for mold on the bread or crust or an off smell. 

What are Uncrustables?

Uncrustables are soft bread sandwiches between a layer of peanut butter and grape. You can make Uncrustables from scratch or buy ones that are manufactured by Smuckers. Uncrustables are frozen sandwiches that have their crust removed. 

The Smuckers sell a wide variety of sandwiches and spreads including peanut butter sandwiches, Smucker’s fruit spreads, Chocolate Flavored Hazelnut spread, and Jif peanut butter products. The Smuckers also offer whole wheat sandwiches with reduced sugar. 

The main ingredients in Uncrustables used to be high fructose corn syrup, hydrogenated oil, and processed butter until the company removed high fructose corn syrup as the ingredient and replaced it with sugar.

The crust of the sandwiches comes from the company which is used to make animal feed. 

When you freeze Uncrustables, flash freeze them for two hours and then divide them into separate bags to accommodate them accordingly, or use one large bag to freeze all the Uncrustables together.  

How to make Uncrustables at home?

Lay two or more slices of bread on the counter or table to let them dry. Place a dollop of peanut butter on the center of both your slices. Smear grape jelly over the peanut butter.

Use a sandwich sealer and decruster to get rid of the crust and crimp the edges of the bread. Put the sandwiches in a sandwich bag, Ziploc bag, or a freezer safe bag and put it in the freezer. 

Eat it within two weeks. Use the removed bread crust to make croutons or salad. You could also add to your animal or bird feed. 

What is the nutritional value of Uncrustables?

Uncrustables are not considered to be healthy or a low caloric food. According to the ground rules set by the FDA, healthy food must have low fat and saturated fats; less than 90 grams of cholesterol, and at least one of either Calcium, Iron, proteins, fiber, potassium, or vitamin D. 

Uncrustable sandwiches are high in sugar unless you buy the reduced sugar version. 

Roll-ups and bites will have as little as 3 grams of sugar while thaw-and-eat sandwiches can contain up to 10 grams of sugar. 

If you buy reduced sugar peanut butter, grape spread or strawberry spread on a whole wheat sandwich it will have as less as 7 grams of sugar per serving. 

The fat content in Peanut butter and grape sandwiches is 9 grams of total fat out of which 2 grams are saturated fat. 

How to defrost Uncrustable quickly?

If you do not have time to thaw the Uncrustables at room temperature or in the fridge, you can use the microwave or a bowl of warm water. 

Microwave Uncrustables at high power for 30 seconds. A bowl of warm or hot water will take 5-10 minutes to thaw the sandwich. 

You can use a toaster or an oven to defrost, even though it is not recommended. This method will take you about 5-10 minutes. 

An unconventional way to defrost Uncrustable is to use a hair dryer to blow over it for a few minutes.
