I was surprised by just how well McDonald’s French Fries reheat in an air fryer. They’re not 100% as perfect as fresh from the fryer fries, but they’re pretty close.

For the above recipe I am using fries that are cold from the fridge, lukewarm fries might only need a minute to revive (if you’re looking to quickly bring them back to life after a drive thru take out order).

We recommend investing in a kitchen thermometer like the Habor Meat Thermometer to ensure your food is thoroughly cooked. It's quick, under twenty bucks and it's waterproof - and hey - we get a small referral fee for any purchases.
