How Long Can Uncrustables Sit Out? [Avoid Food Poisoning]

Uncrustables is a sandwich created by Smuckers that mimics the traditional peanut butter and jelly sandwiches with the crust cut off. Your kids love them, so you picked them up at the grocery store.

You took one out to let it defrost, per the instructions and forgot it on the counter. How long can Uncrustables sit out before going bad?

When defrosting Smuckers Uncrustables, follow the manufacturer’s instructions. Uncrustables must be consumed in 6 to 8 hours once it’s thawed.

But, this sandwich can go bad very quickly due to the processed peanut butter. Defrosted Uncrustables last in the fridge for 24 hours at the most. Do not microwave Uncrustables. 

The US Department of Agriculture advises that food of any kind shouldn’t be left out longer than 2-hours because it moves into the Danger Zone. This is the temperature range between 40 degrees Fahrenheit and 140˚F.

The Danger Zone is the perfect breeding ground for harmful bacteria that can cause food poisoning. 

According to food safety experts, salmonella can develop in peanut butter. In 2012 there was a recall of Uncrustables sold to a school due to a risk of salmonella.

According to the FDA, food that sits out longer than 2 hours moves into the Danger Zone area we mentioned earlier. While other articles say they can sit out for eight hours, we recommend sticking to the 2-hour guideline, especially since you’re dealing with processed peanut butter. 

The 2-hour window begins when the Uncrustable is defrosted. We also recommend letting Uncrustables thaw in the refrigerator instead of the counter. It may take longer, but it’s safer.

It seems, when it comes to Uncrustables, be sure to finish what you defrost sooner than later. If you left it out longer than 2-hours, we recommend disposing of it, defrosting another when you’re hungry. While wasting food is never good, peanut butter is risky, and we shouldn’t take foodborne illnesses lightly.

Can You Make Your Uncrustables?

Yes. If you don’t want to fill yourself or your family with processed foods and preservatives, you can grab the whole wheat bread and your favorite fillings. If you have a nut allergy, there are alternatives. You can even opt for sugar-free jelly. 

Things you will need include bread, natural peanut butter (or allergy-safe alternative), grape jelly (or another flavor of your choice), a sandwich sealer or a fork, and a round cookie cutter.

Sealers are lovely because all you do is press and go. The cookie-cutter method requires sealing the edges with a fork, which is time-consuming. If you foresee this becoming a regular thing in your home, invest in a sandwich sealer. You can find them pretty inexpensively. 

Directions if you have a sandwich sealer. 

  • Lay down one piece of bread.
  • Put the second piece of bread over it. 
  • Use the sealer to cut out rounds. 
  • Spread your fillings in one round. 
  • Seal the second piece of bread over it with the sandwich sealer. 

Directions with a fork and cookie cutter. 

  • Stack two pieces of bread. 
  • Cut them with the cookie cutter.
  • Spread the fillings on one piece of bread
  • Seal the second round piece of bread over the filling around the edges by crimping it with a fork. 

Can You Freeze Homemade Uncrustables?

Yes. Put them in an airtight container and stick them in the freezer. They’ll last there for three months and defrost nicely in the fridge. The best thing about homemade sandwiches is the fact that you know what’s gone into that lunch or PB&J breakfast food. 

When you make your lunches with real food, you can skip harmful ingredients like high fructose corn syrup, which has been entirely from mass-produced Uncrustables as well.

Your 18-pace of Smuckers Uncrustables hasn’t contained high fructose corn syrup since 2017. Smuckers and their retail partners have welcomed the change. 

Can You Defrost Uncrustables In The Microwave? 

Smuckers highly discourage consumers from defrosting Uncrustable sandwiches in the microwave. The jelly heats up to a high heat that can be dangerous, so it’s best to follow the defrosting directions set by the manufacturer. Smuckers says to let your sandwich sit out at room temperature for 30-minutes. 

But remember, the USDA warns us about letting food sit out for longer than 2-hours. Otherwise, it moves into the dreaded Danger Zone. Unrefrigerated Uncrustables that have a moist spot might be a sealed specimen of dangerous bacteria. 

The scientific method works well in a laboratory with a control group. But your kitchen isn’t a lab, and you don’t want to risk foodborne illness. 

Note: Never defrost Uncrustables in warm water. It will soak up the water.
