how to crisp leftover french fries
The nuanced texture of fried foods, such as french fries, is beyond a microwave ovenâs capabilities. A toaster oven or regular oven provides a superior way to reheat french fries or any other fried food. Step 1: Spread Out the Fries. Place the fries on a small metal baking tray and spread them out in one layer. Avoid crowding them on the tray. Set the temperature to 350 F. Any hotter and the fries may burn before they heat through. Slide the tray into the toaster oven and reheat the fries for 5 to 7 minutes.
