If you want to keep French fries in the refrigerator, you can do the following:

1. Put them in a fresh-keeping bag or a sealed bag. Put the remaining French fries in a self-sealing bag or a sealed bag, compress the air and squeeze it out as much as possible. Then put the bag in the refrigerator.

2. Put the French fries on the ice tray. Put the cut French fries on the ice tray, and then put the whole ice tray in the freezer.

3. French fries were fried before they were put in the refrigerator. You can also fry the French fries before putting them in the refrigerator. They will become slightly brittle and then be stored in the above way.

when you are ready to reheat the French fries, you can put them in the oven or simply heat them in the microwave oven, and let them cool a little before eating.

Please note, however, that French fries may lose their original taste and texture after freezing, so it is best to make sure whether you will continue to use these French fries before freezing. It is also recommended to eat frozen French fries within 24 hours.
