Air fryers are a great way to make French fries quickly, and they can be healthier than deep-fried potatoes. The temperature and timing will depend on the type of potato and the size of the fries. For example, russet potatoes are recommended for frying, while Yukon golds are better for roasting. Thicker fries will be crispier on the outside and retain a soft inside, while thinner fries may lose their creamy texture. The temperature for cooking French fries in an air fryer can range from 375 to 400 degrees Fahrenheit, and the timing can range from 10 to 20 minutes.

Preheat the air fryer
Preheating your air fryer is a crucial step in ensuring your fries cook evenly and efficiently. While some recipes and air fryer models may not require preheating, doing so can help you achieve the desired level of crispiness and browning for your fries. Here is a step-by-step guide to preheating your air fryer for cooking fries:
Start by setting your air fryer to the desired temperature. The ideal temperature for cooking fries is typically between 360°F and 400°F. The specific temperature may vary slightly depending on the type of air fryer you have. For example, a basket-style air fryer may require a higher temperature, such as 380°F, while a toaster oven-style air fryer may operate at a lower temperature, such as 360°F.
After setting the temperature, toggle the timer to match the desired cooking time for your fries. This will vary depending on the thickness of your fries and the specific model of your air fryer. For example, thinner fries may cook in as little as 10 to 13 minutes, while thicker fries may require up to 20 minutes. It is important to refer to the instructions for your air fryer and adjust the timing accordingly.
Once you have set the temperature and timer, allow your air fryer to preheat for a few minutes. This duration can range from 2 to 15 minutes, depending on the model and your personal preference. During this time, you can prepare your fries by slicing them to the desired thickness and shape. It is recommended to cut the potatoes lengthwise into 1/4-inch or 1/2-inch slices before cutting them into sticks of a similar size. This ensures that the fries cook evenly.
While the air fryer is preheating, you can also prepare the fries by soaking them in cold water. Soaking removes excess starch, resulting in crispier fries. The duration of soaking can vary from an hour to up to 24 hours, depending on your preference. After soaking, make sure to pat the fries completely dry with paper towels before adding any oil or seasoning.
Finally, after the preheating cycle is complete, you can add a light coating of oil to the fries. The type of oil you use is a matter of personal preference, but options include olive oil, vegetable oil, canola oil, or any neutral-tasting oil with a high smoke point. Toss the fries with the oil, ensuring they are evenly coated, and then add any desired seasonings, such as salt and pepper.
By following these steps, you can effectively preheat your air fryer and prepare your fries for cooking. Remember to refer to your air fryer's instructions for model-specific guidelines and always adjust timing and temperature as needed based on your personal preferences and the results of your first batches.

Cut and soak potatoes
To make French fries in an air fryer, you'll first need to cut and soak your potatoes. While this step can be skipped if you're short on time, soaking your potatoes in cold water for 30 minutes to an hour or even overnight helps to remove excess starch, which will make your fries crisp up more in the air fryer.
To cut your potatoes, use a mandoline or a sharp knife. If you want your fries to cook at the same rate, aim for them to be of similar size, around 1/4-inch thick. However, if you prefer your fries to have a creamier centre, you can cut them into 1/2-inch thick slices instead. You can peel your potatoes, but leaving the skin on helps the fries crisp up nicely as they cook.
Once you've cut your potatoes, completely submerge them in cold water and leave them to soak. After they've finished soaking, pat your potatoes dry with a paper towel. This will help to remove any remaining starch and water, ensuring that the oil and seasonings you add later will properly coat the potatoes.

Oil and seasoning
The amount of oil you use will depend on how many fries you are making and how much oil you want to ingest. For two large russet potatoes, a full tablespoon of oil will make the fries a little dry, which means each person will eat about 1/4 tablespoon of oil. You can experiment with the amount of oil you use to suit your personal taste.
If you are using frozen fries, you don't need to add any extra oil as they are pre-cooked and won't stick. However, you can add a light mist of cooking spray to the bowl when you toss the fries with salt and pepper.
For fresh potatoes, you should toss the fries in a bowl with the oil and seasonings to coat them before placing them in the air fryer. You can use olive oil or duck fat, and season with salt, pepper, garlic powder, paprika, onion powder, rosemary, thyme, or Italian seasoning. For Cajun fries, add chili powder, cayenne pepper, or a pre-made Cajun seasoning. For a rustic French twist, try Herbs de Provence salt.
If you want to make garlic butter fries, brush the fries with butter, diced garlic, and finely diced parsley in the final 15 minutes of baking time.

Air fryer temperature and time
The temperature and time for cooking fries in an air fryer depend on various factors, such as the type of potatoes used, the thickness of the fries, and the desired level of crispiness. Here is a comprehensive guide to help you achieve the perfect air-fried fries:
Temperature:
The ideal temperature for cooking French fries in an air fryer ranges from 375 to 400 degrees Fahrenheit. Some recipes recommend preheating the air fryer to 375 degrees Fahrenheit, while others suggest a higher temperature of 380 or 400 degrees Fahrenheit. The higher temperature range of 400 degrees Fahrenheit is particularly suitable for frozen French fries.
Time:
The cooking time can vary depending on the desired level of crispiness and the thickness of the fries. For thinner fries, about 1/4-inch thick, a shorter cooking time of around 10 to 15 minutes is recommended. For thicker fries, about 1/2-inch thick, a longer cooking time of up to 20 minutes may be needed. It is important to keep an eye on the fries and adjust the cooking time accordingly, as every air fryer is different, and factors like humidity can also impact the cooking process.
Tips for Optimal Crispiness:
To achieve the perfect crispiness, there are a few additional tips to consider. Firstly, cut the potatoes into evenly sized pieces to ensure even cooking. Secondly, soak the cut potatoes in cold water for at least 30 minutes, or even overnight, to remove excess starch and promote crispiness. After soaking, ensure the potatoes are completely dry before placing them in the air fryer. Finally, arrange the potatoes in a single layer in the air fryer basket, leaving some space between each fry to allow hot air to circulate. During cooking, toss or shake the fries occasionally to ensure even cooking and browning.
Seasoning:
Seasoning plays a crucial role in enhancing the flavor of your air-fried fries. Before cooking, toss the cut potatoes with olive oil, salt, and pepper. You can also experiment with other seasonings, such as rosemary, garlic salt, or your favorite spice blend. After cooking, taste and adjust the seasoning as needed before serving.
Warming and Serving:
To keep your air-fried fries warm while cooking additional batches, place them on a baking sheet lined with paper towels and set them in a warm oven at a temperature of 200 to 250 degrees Fahrenheit. This prevents the fries from becoming cold or soggy, and it also allows any excess oil to drip off. Serve the fries hot, and enjoy the crispy, golden goodness!

Serving and storing
When serving your fries, it's best to eat them straight after cooking. However, if you have multiple batches to cook, you can keep the first batches warm by placing them on a wire rack in a single layer in a warm oven (around 200°F or 93°C). This will prevent them from becoming cold or soggy.
If you have leftovers, allow the fries to cool entirely before storing them in an airtight container in the refrigerator. They can be stored for up to 3–5 days and can be frozen for up to 2 months. To reheat, simply place the fries back into the air fryer at around 375°F (190°C) for about 5–10 minutes until warmed through and crispy. You can also reheat them in a little oil in a hot cast-iron pan or skillet.
