Should Leftover French Fries Be Refrigerated?
Yes, leftover French fries should be refrigerated to prevent the growth of bacteria and to retain their quality. Leaving them at room temperature can lead to spoilage and can cause foodborne illnesses. To refrigerate the French fries, place them in an airtight container or resealable plastic bag and store them in the fridge for up to three days. If you want to reheat them, place them in the oven or air fryer for a few minutes to regain their crispiness.
