What You'll Learn

Temperature and timing
The timing of the cooking process is contingent upon the thickness of your chips. For standard-sized chips, approximately 20 minutes in the air fryer should suffice. However, if you're craving thicker chips, such as steak fries, wedges, or homestyle cuts, allot an additional 5 to 10 minutes. Thinner variants like French fries or waffle, curly, and crinkle cuts usually require less time, often needing only 10 to 15 minutes.
During the cooking process, it's essential to shake the basket or flip the fries every 5 minutes. This ensures an even cook and aids in achieving that desirable golden-brown exterior. If you're cooking in batches, be mindful of overcrowding the basket, as this can hinder even cooking.
While the cooking time may vary based on chip thickness and your desired crispiness level, the optimal temperature setting for achieving perfect air-fried frozen chips remains constant at 200°C/400°F.

Oil and seasoning
While it is not necessary to add oil to frozen chips when cooking them in an air fryer, it is recommended to mist them with some olive oil or vegetable oil when they are finished cooking. You can also spritz the fries with a little bit of oil before they go into the air fryer to help them crisp up. If you want to add extra flavour, you can also coat the frozen chips in oil and seasonings before placing them in the air fryer.
Most frozen fries already come oiled, but you can spray them with some cooking oil if they seem too dry. McCain fries, for example, normally have a combination of 5% oil and 95% potatoes. If you want to add extra flavour, you can also coat the frozen chips in oil and seasonings before placing them in the air fryer.
When it comes to seasoning, you can experiment with a variety of spices and herbs such as paprika, garlic powder, onion powder, curry powder, Cajun spice, garlic salt, or mixed herbs. You can also add a sprinkle of grated vegan cheese for added flavour. If you want to keep it simple, just add some salt and pepper.

Layering and spacing
Firstly, it is essential to arrange the frozen chips in a single layer within the air fryer basket. Avoid the temptation to stack or overcrowd the chips, as this can hinder even cooking and lead to soggy spots. Aim for a spaced-out layer of fries with ample room for hot air circulation. This circulation is the key to achieving that coveted crispiness. Depending on the size of your air fryer, you may need to cook the chips in batches to avoid overfilling.
Next, be mindful of the chip-to-chip spacing. While it's not necessary to arrange the chips in a perfect pattern, ensure they are not clumped together. A good rule of thumb is to leave a slight gap between each chip, allowing the hot air to reach all surfaces. This spacing will help ensure that each chip crisps up evenly. Remember, if your air fryer is overloaded, you may end up with undercooked fries.
Additionally, consider the size and shape of your chips. Thicker cuts, such as steak fries or wedges, may require a bit more space around them due to their longer cooking time. On the other hand, thinner cuts like French fries or crinkle-cut chips can be arranged slightly closer together, as they cook faster and don't need as much breathing room. Adjust your layering and spacing technique accordingly.
Lastly, don't forget to shake the basket or flip the chips periodically during the cooking process. This simple step ensures that all sides of the chips get their turn at the bottom of the basket, absorbing the most heat and achieving that perfect golden brown colour. By following these layering and spacing instructions, you'll be well on your way to enjoying delicious, evenly cooked, and crispy frozen chips from your air fryer.

Choosing the right chips
Type of Chips
The type of frozen chips you choose will depend on your personal preference. There are various options available, such as French fries, straight-cut, curly fries, waffle fries, steak fries, and crinkle-cut fries. Each type of chip will have a slightly different cooking time and temperature recommendation, so be sure to adjust accordingly.
Brand
While you can use any store-bought brand of frozen chips, some brands are specifically mentioned as being well-suited for air frying. These include McCain, Aunt Bessie, Sainsbury, Asda, and Tesco. McCain's crinkle-cut chips are often recommended as they deliver a perfect combination of crunch on the outside and fluffiness on the inside. However, it's worth noting that McCain's thin-cut and sweet potato chips may burn or emerge gnarled, respectively. If you're looking for something different, Birds Eye's golden ale beer-battered chips are thick-cut and deliver a satisfying crunch. For a healthier option, consider Seasons Pride's low-cholesterol sweet potato chips from Aldi, which offer a good crunch-to-fluff ratio.
Size and Thickness
The size and thickness of the chips will impact the cooking time. Thicker chips like steak fries, wedges, or homestyle cuts will take longer to cook, usually requiring an additional 5-10 minutes. On the other hand, thinner chips like French fries or waffle, curly, and small crinkle cuts will cook faster, typically taking around 10-15 minutes.
Oil Content
When choosing frozen chips, consider whether they are pre-coated in oil. Adding extra oil before air frying may not yield better results, and it is not necessary as the air fryer uses hot air to cook the chips. However, if you prefer crispier chips, you can try spritzing them lightly with oil before placing them in the air fryer.
Ingredients
Check the ingredient list on the frozen chip packaging. Some may have a simpler ingredient list, containing just potato, oil, and dextrose. Others may have additional ingredients like pea fibre, pea protein, and thickening agents. Choose the option that aligns with your dietary preferences and requirements.

Health benefits
Air fryers are marketed as a healthier alternative to deep-fat frying, and for good reason. By using hot air instead of submerging foods in oil, air fryers significantly reduce the amount of fat and calories in your food. This can help with weight management and lower your risk of obesity-related health issues, such as type 2 diabetes and cardiovascular disease.
Research has found that air-fried foods contain 70% to 80% fewer calories than deep-fried foods. They also have far less fat, reducing your risk of heart disease. This is especially true when cooking starchy foods like potatoes, which, when fried in oil, produce a chemical called acrylamide that has been linked to cancer. Air frying potatoes lowers the amount of acrylamide by 90%.
Air fryers also reduce the risk of safety issues caused by hot oil, such as spilling, splashing, or accidentally touching it. They are also more energy-efficient than conventional ovens and are better at reheating foods than microwaves, which tend to make foods soggy.
However, some studies have found that air frying may have negative health effects when cooking certain foods, like fish. For example, one study found that air-frying sardines decreased their healthy fat content and increased cholesterol oxidation products (COPs), which may negatively affect cholesterol levels. However, the same study found that adding fresh herbs like parsley and chives helped reduce these damaging effects. Another study found that air frying fish reduced its omega-3 fatty acid content, which may be beneficial for heart health.

Frequently asked questions
It takes around 18 to 20 minutes to cook frozen chips in an air fryer. However, the cooking time may vary depending on the size and shape of the chips. For example, thinner chips like French fries may only need 10 minutes, while thicker chips like steak fries or wedges may need an additional 5-10 minutes.
It is recommended to cook frozen chips in an air fryer at a temperature of 200°C/400°F. This temperature will ensure that the chips are crispy on the outside and tender on the inside.
To ensure your frozen chips are crispy, make sure they are not thawed before cooking. Also, ensure the temperature is high enough (200°C/400°F) and that the air fryer is preheated. Additionally, shake the basket or flip the fries every 5 minutes to ensure even cooking and don't overcrowd the basket. You can also try spritzing the fries with a little oil before cooking.
