How To Store Leftover French Toast

French toast is too delicious to believe that you can have leftovers, but it happens. If you’re not planning on eating those leftovers in the next two days or so, it’s better to freeze them.

Some people even choose to make an extra amount of French toast and freeze them for later use.

Refrigerating Leftover French Toast

To refrigerate leftover French toast, simply place them inside a tightly sealed container and throw them in the fridge. Refrigerated leftover French toast lasts for about four to five days.

Freezing Leftover French Toast

Leave your cooked French toast out to cool, then place them on top of each other. Make sure that you put a sheet of wax paper in between each slice to prevent them from sticking together.

Wrap them tightly with foil and/or place them inside a heavy-duty freezer bag. Using this method, your French toast remains good to eat for one to two months.

How To Reheat Leftover French Toast

There are three ways to reheat leftover French toast. Of course, if it’s frozen, let it sit overnight in the fridge to defrost.

Use one of these methods to reheat defrosted French toast:

  • In the Oven: Place the defrosted French toast on a baking sheet in a preheated oven for about two minutes.
  • In the Microwave:Use the microwave to reheat French toast for no more than 30 seconds. Note that it won’t be crispy though.
  • Over the Stove:Grease a pan to reheat your French toast over medium fire. A minute or two on each side is more than enough.

Can You Eat French Toast That Was Left Out Overnight?

The USDA says that you should throw away any food that’s been left out for more than two hours. That’s because bacteria grow incredibly fast at room temperature.

These bacteria can make you sick, even if you reheated that food. However, there are certain types of food that don’t need to be stored in the fridge, such as bread, butter, and some condiments.

Unfortunately, French toast is not an exception. So, it’s better not to eat French toast that was left out overnight.

Can You Get Food Poisoning From French Toast?

Yes, you can get food poisoning from French toast. As previously mentioned, if not stored within two hours of cooking, French toast can be unsafe to consume.

Similarly, if it stayed in the fridge for more than five days, French toast can go bad and you shouldn’t be eating it. That’s because the fridge doesn’t prevent bacterial growth, it just slows it down.

Eating French toast that’s gone bad may cause many symptoms, including vomiting, stomachache, or diarrhea.

Final Thoughts

French toast is so versatile. You can basically add anything on top of it and it turns into a different dish. Whether whipping cream, fruits, ice cream, or nuts; French toast is always enjoyable.

Even if it was made the night before, there are many ways it can be altered to make it even better. So, what to do with leftover French toast?

Bake it, fry it or even reheat it. Whatever you choose, you’ll definitely end up with a tasty treat.
