Heat up those leftover fries and turn them into french fry nachos!
WHY SHOULD I REHEAT FRIES IN THE AIR FRYER?
There are lots of good reasons to use your air fryer to reheat fries and other foods, but the true fact is that crispy leftover french fries are not only possible with the help of your air fryer, they are easy, and completely delicious.
It takes just 4 minutes to reheat fries in the air fryer. A bit longer than the microwave, but the results are well worth the small time investment.
Reheating french fries in the microwave will never give you the result you're looking for, which I assume is french fries that taste like they just came out of the fryer!
The air fryer can revive leftover french fries to their original glory! Leftover fries reheated in the air fryer are hot, crispy, and the closest you can get to fresh.
Once you know how to reheat fries in the air fryer, you won't need to waste fries anymore. I don't know about you, but I can't always finish all of my fries in one sitting. Save your leftover french fries instead of throwing them out, and enjoy them later like they were just made.
TIPS FOR REHEATING FRIES IN AIR FRYER
- This method works with any type of leftover french fries. Try it with Mcdonald's fries, Chick-Fil-A waffle fries, Arby's curly fries, leftovers from restaurants, or the frozen fries you made last night for dinner. In the image above, you can see that I'm reheating a pile of fast food fries that my kids didn't eat but wanted to save for later.
- Reheating fries in the air fryer gives you the perfect opportunity to add extra seasonings to them.
- You don't need to add any extra oil. There is oil in or on the fries already and the air fryer will use that to crisp them back up again.
- Follow these simple instructions for reheating fries in the air fryer, and be sure not to overcook them. Your fries will be best when they are just heated through and the crispiness is reactivated. If overcooked, they could dry out.
- The only other rule is to be sure not to overcrowd the basket. You don't need to keep them in a single layer, but you do want plenty of room in the air fryer for air to circulate.
HOW TO REHEAT FRIES IN AIR FRYER
- Start with cold, leftover french fries. Again, any kind of previously cooked fries can be reheated in the air fryer! In the images I'm using showstring fries from a fast food restaurant.
- Add the fries to the air fryer. While you don't need to keep the fries in a single layer, you should avoid layering them more than 2 deep. This will let them crisp up quickly and evenly.
- Air Fry! It takes 3-4 minutes at 400°F/200°C to reheat french fries. Thicker fries may take an extra minute or two. Shake the basket once after about 2 minutes to be sure that everything is reheated evenly.
- Serve reheated fries immediately. They are best if enjoyed right away, with ketchup, barbecue, or your favorite dipping sauce.
These numbered steps match the numbered photos above and are for illustration purposes. For the full instructions for reheating fries in the air fryer, see the recipe below.
MORE AIR FRYER TIPS FOR REHEATING FRENCH FRIES
- The actual time it takes to reheat your fries in the air fryer will depend on the amount that you're cooking and the size of the fries. Add extra time for thick steak fries or waffle fries. If you only have a handful of fries to reheat, reduce the time.
- As always, keep a close eye on your food while it's reheating in the air fryer to avoid overcooking it.
- Add any seasonings before or after cooking. Seasoned salt is my go-to french fry seasoning.
- Oil isn't necessary, but you can add some if you want extra, extra crispy french fries. I suggest spraying on a very small amount if you want to try this.
HOW LONG DOES IT TAKE TO REHEAT FRIES IN AIR FRYER?
I've found that most french fries will reheat well in the air fryer at a high temperature within 3-4 minutes.
Some types of thicker french fries, including steak fries, waffle fries, potato wedges, and curly fries, might need an extra minute or two to reheat fully.
Very thin fries may be done in 2-3 minutes, depending on how fast your air fryer heats up.
WHAT ELSE CAN I REHEAT IN THE AIR FRYER?
You can reheat lots of things in the air fryer! Using a 400°F/200°C air fryer and a short amount of time is the best way to reheat smaller food pieces, such as french fries, sweet potato fries, tater tots, chicken nuggets, shrimp, onion rings, and more!
HOW LONG DO LEFTOVER FRENCH FRIES KEEP?
It's best to enjoy your leftover fries within 4 days. Keep them in an airtight container rather than the takeout box they came in to keep them fresher longer.
WHAT IS THE BEST WAY TO REHEAT LEFTOVER FRIES?
It's definitely in the air fryer! No other appliance can reheat french fries as well as the air fryer can.
WHAT TO DO WITH LEFTOVER FRENCH FRIES
So you have some leftover fries in the fridge and you want to make them into something special?
Try adding some cheese! Cheese makes everything better, truly. Use your air fryer to make loaded cheese fries.
Once the fries are crisped up, add a handful of shredded cheddar or Monterray Jack cheese. Air fry for another minute to melt the cheese.
Want more toppings? Add some cooked pieces of bacon on top of the melted cheese, and serve with sour cream to make the most delicious loaded fries from your leftovers.
CAN I REHEAT LEFTOVER SWEET POTATO FRIES?
Yes! Sweet potato fries reheat just as wonderfully in the air fryer as regular french fries do. Keep a close eye on them, as sweet potatoes can burn easily if overcooked due to their sugar content.
CAN I FREEZE LEFTOVER FRIES?
You can freeze leftover fries, but I don't recommend it. The texture of potatoes changes quite a bit when they are frozen after they are cooked, and they will not reheat as well.
