Yes, it is recommended to store homemade crepes in the refrigerator to prevent any bacterial growth, especially because they contain perishable ingredients like milk and eggs.

You can stack them with parchment or waxed paper between each crepe to prevent them from sticking, then place them in an airtight container or a zip-top bag.

They can be stored this way for up to 2 days in the fridge. For longer storage, you can freeze them by separating them with waxed paper.

If you leave them at room temperature, do not exceed a few hours for food safety reasons.

Indeed, even though cooking the eggs and milk eliminates a large part of the initial bacteria, crepes remain a perishable product that can develop microorganisms if left at room temperature for more than a few hours.
