How to make the world’s crispiest air fryer fries
A few techniques help me get the most out of my air fryer when cooking frozen goodies like french fries, chicken tenders and tater tots.
1. Preheat the air fryer
You don’t need to preheat the air fryer but it will produce crispier fries.
When you add your fries, the hotter your air fryer is, the more golden brown and crisp they’ll become. Not every air fryer has a preheat function but you can run yours for about 5 minutes at the desired temperature to get the chamber nice and hot before you add the food.
2. Use a light spritz of oil
A light spritz of oil will ensure your air fryer fries don’t dry out.
Some people swear by spraying a little of their go-to cooking oil, like canola, olive or avocado, into the basket and over frozen french fries before air-frying. The idea is that the extra oil helps the food brown and crisp up. You don’t need to go nuts with oil, but a light coating helps seal the potato strings in a divinely crispy crust.
An oil mister or spray bottle will help with an even and light coating of oil.

3. Avoid overcrowding the basket
Try not to crowd your fries in the basket.
Air fryers create convection heat by using a fan (the noise you hear when you turn the machine on) to circulate air around the food, cooking it faster and creating that crunchy exterior we want. For convection cooking to work well, your french fries need to have as much surface area exposed as possible. That means loading up batches of fries in a single layer and leaving just a little space between each piece, if possible. The result is tastier fries in a shorter cooking time.
4. Shake for even cooking
Shake a few times during cooking for an even browning.
Halfway through the cooking time, pull out your air fryer’s basket and shake it well. This will help your fries brown more evenly. Try to get the fries back in a single layer before popping the basket back in and finishing the process.

In my world, a pile of fries and a salad with a zippy vinaigrette need no other accompaniment (except a glass of wine).
