how long to reheat fries in air fryer (tip #3 is a must)

how long to reheat fries in air fryer

If you’re like most people, you probably have some leftover fries sitting in your fridge. And let’s be honest, reheating them in the microwave just doesn’t give you that crispy texture that we all love about french fries. Luckily, air fryers, just like refrigerators, are a game-changer when it comes to reheating leftovers – and especially for those delicious golden sticks of potato goodness.

So how long does it take to reheat fries in an air fryer? It generally takes 5 – 7 minutes to reheat your fries in an air fryer. It also depends on a few different factors such as the number of fries being reheated, the type of air fryer used, and personal preference on crispiness level. In this article, we’ll go over some general tips and tricks for reheating french fries using an air fryer.

Tip 1: Preheat Your Air Fryer

Before putting your leftover fries into the air fryer basket make sure to preheat your appliance first. This will help ensure even heating throughout the cooking process which will lead to perfectly ‘re-fried’ potatoes every time.

To preheat simply set your preferred temperature (around 375°F is ideal) and allow it to heat up for around three minutes before placing your frozen or refrigerated food inside.

Tip 2: Check Frequently

It’s important to check frequently when reheating French Fries as they can quickly overcook if left unattended. Depending on how many pieces there are this may vary but checking every minute or so should give enough insight into whether they need more time or not.

When checking frequently make sure not only visually but also by testing doneness with a fork or tongs – do they feel crunchy enough? Soggy spots indicate uneven cooking so flip/turn any affected parts midway through!

Tip 3: Keep Them Moist

One downside of using an air fryer is that sometimes foods can dry out during the cooking process. This is especially true for fried foods like french fries. To keep your leftover fries from drying out in the air fryer, try lightly spritzing them with water before reheating.

Another trick to maintaining moisture is to place a damp paper towel on top of the fries while they cook. This will help steam them and prevent them from becoming too crispy or tough.

Tip 4: Be Mindful of Timing

When reheating French Fries using an air fryer it’s important to be mindful of timing as overcooked fries can become hard or even burnt.

Generally speaking, refrigerated french fries take around 5-7 minutes to reheat in an air fryer whereas frozen ones may need closer to 10-12 minutes depending on their thickness and quantity being cooked at once.

It’s also worth noting that different types of air fryers operate differently so always read through your appliance manual beforehand!

Tip 5: Shake Them Up

To ensure even cooking and crispiness all throughout shake up the basket midway through cooking time – this helps redistribute hot spots which could be causing uneven doneness (also known as “hot pockets”).

For best results, transfer your preheated leftovers into a single layer inside the basket without overcrowding and then shake every few minutes thereafter until they’ve reached desired texture level.

Can I Put Foil In An Air Fryer?

Using aluminum foil in an air fryer has been debated among home cooks for years – some say it’s perfectly fine while others claim it can cause damage or even pose a fire hazard. So what’s the truth? Can you put foil in an air fryer?

The answer is yes, you can use foil but with caution! One major benefit of using aluminum foil when cooking food such as chicken wings or fish fillets is that it prevents sticking which makes cleaning up afterwards much easier.

However one must be mindful of the following:

Tip 1: Don’t Block Airflow

If you choose to use foil in an air fryer, it’s important not to block any airflow. This is because air circulation is one of the main factors that make an air fryer a healthier cooking option compared to traditional frying methods.

To avoid blocking airflow, make sure that your foil doesn’t cover up all parts of the food item or touch any heating elements within the appliance.

Tip 2: Keep It Thin

Another thing to keep in mind when using foil in an air fryer is its thickness. Thicker pieces can easily cause uneven heating which could lead to hot spots and ultimately burnt areas on your food.

Aim for thin layers of aluminum foil – enough just as needed so it won’t interfere with crispiness levels but thick enough where there’s no leeway for sticking accidents!

Tip 3: Take Precautions

Lastly, always take precautions when cooking with aluminum foil – especially if you’re still getting used to how your particular model works.

For instance, some appliances may require preheating while others don’t; additionally, certain models might have specific warnings about what types of foods should be cooked without using this handy kitchen tool altogether (e.g., acidic ingredients).

Always check manufacturer instructions before beginning any recipe involving aluminum foil so as not to put yourself or anyone else at risk.

How Do You Make Air Fries Crispy Again?

We’ve all been there – leftover french fries that are now limp and soggy. Thankfully, giving them new life by re-crisping them up using an air fryer is easier than ever.

Here are some tips for making those sad spuds crispy again:

Tip 1: Reheat Them First

Before attempting to crisp up old French Fries make sure they’re properly reheated first – otherwise, you run the risk of creating super hard/chewy centers inside and still having limp outsides – just like a raw baked potato whose center hasn’t heated up enough!

Tip 2: Add Some Oil

Adding some oil can help with achieving crispy fries when reheating. You don’t need to go crazy on the amount, however – only a few spritzes or drizzles should suffice.

Coconut oil is one great option because it has high smoking points (meaning it won’t burn too easily) and adds depth of flavor without overpowering any other flavors present in the dish such as seasoning.

Tip 3: Use The Right Temperature

When cooking french fries in an air fryer always aim for around 375°F which will give them optimal crispiness while avoiding burnt spots. Cooking at lower temperatures may result in soggy or undercooked results while higher temps can be risky leading to overcooking faster than expected.

Also, remember that food items absorb heat differently so timing and temperature may vary depending on what else you’re cooking alongside your French Fries.

How Do You Keep Fries From Drying Out In An Air Fryer?

One common problem when cooking french fries using an air fryer is drying out – this occurs more frequently if they’re not properly stored beforehand or if you simply leave them inside the appliance for too long during the reheating process.

Here are some tips to avoid dried-out fries:

Tip 1: Store Them Properly

Before even beginning to cook make sure your potatoes have been properly stored before being cooked again, whether refrigerated or frozen. This means placing them in an airtight container or sealable baggie within hours after initial frying/air frying so moisture doesn’t escape from potato interiors into the surrounding environment (and thus evaporate).

This also helps prevent freezer burn if freezing leftovers instead of storing them fridge-side!

Tip 2: Don’t Overcook

Overcooking any food item including French Fries can quickly lead to a dried-out texture so always keep an eye on food items in the air fryer, setting and adjusting times as needed.

Also, remember that different appliance models may vary regarding cooking temperatures and duration – when unsure, refer back to manufacturer instructions for guidance!

Tip 3: Add Some Moisture

Lastly, adding moisture during the reheating process can help retain a crispy exterior while keeping the insides tender. Try placing a damp paper towel over your French Fries or lightly spritzing them with water right before they go into the appliance – this will trap steam inside which works wonders at retaining moisture.


Reheating french fries using an air fryer is easy but it does require some careful attention and experimentation to achieve the perfect desired outcome. With these tips in mind, you’ll be able to transform limp leftovers into crisp deliciousness every time!

Just remember – preheating your appliance first, checking frequently throughout the cooking time, being mindful of timing guidelines per model type/manufacturer specifications along with proper storage methods beforehand are all key factors when making sure your next batch tastes just as good if not better than the original serving!
