What You'll Learn

Preheat the air fryer
Preheating your air fryer is an important step in the cooking process. It ensures that your fries cook evenly and have a desirable crispy texture on the outside while remaining soft on the inside. To preheat your air fryer, start by setting the temperature. The ideal temperature for cooking frozen french fries is between 360°F and 400°F (180°C to 200°C). Some sources recommend preheating at 375°F for 10-12 minutes, while others suggest 390°F or 400°F for 10 minutes. Depending on your air fryer model, you may need to experiment with different temperatures and adjust accordingly.
Once you've set the temperature, let the air fryer preheat for 3-5 minutes. This duration ensures that the appliance reaches the desired temperature before you begin cooking your fries. While preheating, you can also prepare your fries by spreading them out in a single layer in the air fryer basket. It is crucial to not overcrowd the basket, as this can lead to uneven cooking and sogginess. If you have a larger quantity of fries, consider cooking them in batches to maintain optimal cooking conditions.
During the preheating process, you may also want to coat the air fryer basket with a nonstick cooking spray, such as vegetable or olive oil spray. However, this step is optional, as some prefer to omit the oil entirely for a healthier option. Frozen french fries are typically already coated in oil, so additional oil may not be necessary. Check the ingredients on the package of your frozen fries to determine if they require extra oil.
While your air fryer is preheating, you can also prepare any seasonings you may want to add to your fries. Common seasonings include salt, pepper, garlic powder, onion powder, or paprika. You can also opt for seasoned salt or a specific spice blend to add extra flavor to your fries. Remember, the preheating process is crucial for achieving the desired texture and cooking your fries evenly, so allow sufficient time for your air fryer to reach the set temperature before adding the fries and beginning the cooking process.

Don't overfill the basket
When cooking frozen French fries in an air fryer, it is important to avoid overfilling the basket. This is a crucial step to ensure even and efficient cooking. Overfilling the basket can lead to uneven cooking, resulting in soggy or undercooked fries. It is best to arrange the frozen fries in a single layer, leaving enough space for hot air to circulate. This allows the hot air to reach all the fries, ensuring they cook evenly and become crispy.
The size of your air fryer and the quantity of fries you wish to cook will determine the appropriate amount for your fryer basket. As a general rule, fill the basket only halfway to allow for adequate air circulation. If you are cooking a large batch, it is better to cook the fries in multiple smaller batches to ensure even cooking.
By not overcrowding the basket, you also prevent the fries from sticking together. This ensures that each fry has its own space to cook properly and achieve that desired crispy texture. Overfilling the basket may result in the fries being cramped and steaming instead of crisping up.
Additionally, when the basket is overfilled, the fries may end up touching the heating element of the air fryer, which can lead to burning and an unpleasant taste. So, for the best results, always ensure that you leave enough space in the basket and cook in smaller batches if needed. This way, you'll achieve perfectly crispy and delicious frozen French fries every time!

Shake the basket during cooking
Shaking the basket during the cooking process is an important step in ensuring your French fries cook evenly and become crispy. Depending on the thickness of the fries and the model of your air fryer, you may need to adjust the frequency with which you shake the basket. As a general rule, shaking the basket every 5 minutes or halfway through the cooking process is a good place to start.
To shake the basket, simply remove it from the air fryer, give it a good shake to ensure all sides of the fries are cooked, and then return it to the machine to continue cooking. This step helps to prevent the fries from sticking together and ensures that every bit of every fry cooks evenly.
It is also important to note that overcrowding the basket can cause the fries to cook unevenly and become soggy. Therefore, it is recommended to spread the fries in a single layer in the basket, avoiding any overlap. If needed, cook the fries in batches to avoid overcrowding.
By following these steps and shaking the basket during the cooking process, you can ensure that your French fries come out crispy and cooked evenly every time.

Reheating and storing leftovers
Leftover French fries can be soggy and sad due to moisture migration. But, there is a way to bring them back to crispy, hot, fry-perfection: the air fryer.
To reheat your leftover French fries in an air fryer, preheat the air fryer to between 360°F to 400°F (182°C to 204°C). Place the fries in the air fryer basket in a single layer, avoiding overcrowding so the air can circulate properly. Spritz them lightly with cooking oil for extra crispness.
Cook the fries for 3 to 5 minutes, checking at the halfway mark. Shake the basket or flip the fries to ensure even reheating. Check for crispiness, and if needed, continue cooking for another minute or two until they’re as crispy as you like. For thicker fries, you may need to add an extra minute or two to the cooking time.
If you don't have an air fryer, you can use a conventional oven or a frying pan to reheat your fries.
Leftover fries can be repurposed in many different and delicious ways, reducing food waste and adding flavor to new dishes. For example, you can chop the fries into smaller pieces and use them as a base for a breakfast hash, or transform your leftover fries into loaded fries by topping them with cheese, bacon bits, green onions, and sour cream.
Storing leftovers
Leftover French fries should be stored properly to prevent them from becoming soggy and sad. While the exact method of storage is not specified, storing them in an airtight container in the refrigerator is a common practice to keep food fresh for longer.

Oil and seasoning
While the main benefit of using an air fryer is that you can cook your French fries with less oil, some recipes do call for a small amount of extra oil to be added. This can be done by spraying the fries with olive oil before cooking, or spraying the basket with oil or cooking spray. This helps the salt and seasonings to stick to the fries.
Most frozen French fries will already be pre-coated in oil, so you may not need to add any extra. If you do choose to add oil, it is important not to overcrowd the air fryer to ensure even cooking and maximum crispiness.
When it comes to seasoning, salt is the most popular option, with some recipes calling for seasoned salt. Other seasonings you could use include pepper, garlic powder, onion powder, or paprika. You can also dip your cooked fries in sauces such as ketchup, mayonnaise, or chili sauce.
