The best way to store pizza crust in the refrigerator is to wrap it tightly in plastic wrap or aluminum foil to prevent it from drying out. If you have a sealable plastic bag, you can place the wrapped crust inside to provide an additional barrier against moisture. Store it in the refrigerator for up to two days. To maintain freshness, avoid stacking other items on top of the crust, which could cause it to become flattened. When you're ready to use it, let it sit at room temperature for about 30 minutes to an hour to soften before topping and baking.
