Is it safe to thaw uncrustables in the microwave?

No, uncrustables Sandwiches should not thaw in a toaster or microwave oven.

The current problem with microwave uncrustables is that the mixture inside them gets so hot before the outer bread, and it deceives you of how hot they are if you can’t control how you heat them.

The Uncrustables website’s FAQ section repeatedly states that microwaving the sandwich is not advisable because it can make the jelly excessively heated.

Microwaves operate by absorbing fat and water. But in this sandwich case, both peanut butter and jelly are thick (heat-retaining substances). However, the bread is dry and will take a long time to heat up.

And since most times you have no clue that the inside is high enough to cause burns while the outside is only hot to the touch and you end up heating them for long durations.

But still, if you want to microwave uncrustables, then microwave them for 15-20 seconds after wrapping them in a paper towel. Turn the uncrustable again or microwave for the next 15-20 seconds or until it the hot bread.
