Can You Freeze All-Purpose Flour?
Yes, you can freeze it.

Flour's pantry longevity traces back to how it's milled: the oil-rich bran and germ that shorten whole wheat flour's shelf life have already been stripped out of all-purpose flour, leaving behind a drier, more stable product that holds up for the better part of a year even without refrigeration. Tucking a bag into the freezer stretches that further still, and has the side benefit of killing off any stray pantry-pest eggs before they become a problem. Let it come back to room temperature before baking with it, especially for yeast-based recipes where cold flour can slow the dough's rise noticeably. A sealed container, not the original paper bag, is what actually delivers the upper end of that stated shelf-life range.
Freezing is worth doing as a routine habit specifically for anyone who's ever opened a bag of flour and found small moths or larvae inside — a few days in the freezer right after purchase kills off any pest eggs that were already present before they have a chance to hatch and spread to other stored grains, a preventive step that matters more for flour bought from a bulk bin than a factory-sealed bag. Frozen flour doesn't need to be measured any differently than room-temperature flour, though letting it sit out for a while first, rather than scooping it straight from the freezer, avoids condensation forming inside a mixing bowl on a humid day.
Storage times and safe temperatures are general guidance from USDA FoodKeeper, USDA FSIS, and FDA sources — they are not a guarantee of safety. When in doubt, throw it out. This is not a substitute for professional food-safety advice.
