Air fryers are a great way to cook potatoes that are crispy on the outside and soft on the inside. They are faster than traditional ovens, require less oil, and are easy to use. To make crispy potatoes in an air fryer, you should cut the potatoes into bite-sized pieces, toss them in olive oil and seasonings, and then cook them in the air fryer at 400°F for 10 minutes. After that, shake the basket and cook for another 8-10 minutes, or until they are golden and crispy.

What You'll Learn

Choosing the right potato variety
Starchier potatoes, such as Russets (also known as Idaho potatoes), are an excellent choice for air frying. Russets have a floury, low-moisture interior, which makes them crisp up beautifully with a pale golden colour. Their high starch content produces a satisfyingly crisp crust, while the inside becomes fluffy and mild in flavour.
Another great option is Yukon Golds or Yellow Potatoes. These potatoes will also crisp up perfectly, but due to their lower starch and higher sugar content, they will turn a deeper golden colour. The resulting crisp will be slightly softer than Russets, but their insides will be creamy and full of flavour.
Red potatoes are another variety to consider. When roasted in an air fryer, they will develop an even darker golden brown colour due to their higher sugar and lower starch content.
It's important to note that waxy varieties like new potatoes or fingerlings are not ideal for roasting in an air fryer. These potatoes are better suited for other purposes, such as salads and home fries.
Additionally, the size of the potatoes matters. Look for potatoes that are uniform in size and free from eyes and blemishes. This will ensure even cooking and help you achieve the desired crispiness.

Preparing the potatoes
Start by selecting the right potatoes. Starchier varieties such as Russets (also known as Idaho potatoes) and Yukon Golds are excellent choices for air frying. These potatoes have a floury, low-moisture interior, which makes them crisp up beautifully and develop fluffy insides. On the other hand, waxy varieties like new potatoes or fingerlings are not ideal for roasting.
Cut the potatoes into uniform bite-sized pieces, about 1/2" to 3/4" thick or 1 to 2 inches long. The key is to keep the sizes consistent to ensure even cooking. Try to cut them into similar sizes so that they cook evenly and you don't end up with some burnt and others undercooked.
Next, place the potatoes in a medium-sized bowl and drizzle them with olive oil. You can also experiment with other cooking fats like melted duck fat. Make sure to coat the potatoes evenly. This step not only prevents the potatoes from sticking to the air fryer basket but also helps in achieving that crispy texture.
Now, it's time to season your potatoes. You can simply use salt and pepper, or get creative with your favourite herbs and spices. Try Italian seasoning, garlic powder, Cajun seasoning, rosemary, thyme, or even crumbled cooked bacon. You can also infuse the cooking fat with aromatics such as garlic, rosemary, or thyme to add extra flavour to your potatoes.
After seasoning, it is essential to preheat your air fryer. Set the temperature to 400°F (204°C) for the best results. However, if you're using a Cuisinart Air Fryer, lower the temperature by up to 50°F as it tends to run hotter than basket-style air fryers.
Once your air fryer is preheated, it's time to arrange the potatoes in the basket. Spread them in a single layer, ensuring they have enough room for the air to circulate. This step is crucial for achieving maximum crispiness. If you're cooking a large batch, it's better to cook in batches than to overcrowd the basket.

Using the right amount of oil
Using oil is an important step in achieving crispy potatoes in your air fryer. While it is technically possible to cook potatoes in an air fryer without using oil, the result may be dry. Using a small amount of oil will help you achieve a melt-in-your-mouth texture and a golden colour.
The amount of oil you use will depend on your personal preference and the type of oil you are using. A good starting point is to use about a tablespoon of oil for one pound of potatoes. You can always experiment with the amount of oil you use to find the perfect amount for your taste.
When using oil, it is important to toss the potatoes in the oil to ensure they are evenly coated. You can do this by placing the potatoes in a medium-sized bowl, adding the oil, and then tossing or stirring the potatoes until they are fully coated. This will help ensure that the oil is distributed evenly and will prevent the potatoes from sticking to the air fryer basket.
In addition to oil, you can also add other ingredients to the potatoes to enhance their flavour and crispiness. For example, you can add garlic, Italian seasoning, salt, pepper, and Parmesan cheese. You can also try infusing the cooking fat with aromatics such as garlic, rosemary, or thyme to add even more flavour to your potatoes.

Adding herbs and spices
Before air frying, it is recommended to toss your potatoes with a small amount of oil, such as olive oil, to prevent them from sticking and to ensure a crispy texture. This is also an excellent opportunity to infuse your cooking fat with aromatics and herbs. Garlic is a popular choice, and you can use either garlic powder or fresh garlic. Other aromatics to consider include rosemary, thyme, and Italian seasoning. If you're feeling adventurous, you can even try using melted duck fat as your cooking fat!
Fresh herbs like basil, oregano, and dill can be added after air frying to ensure their flavours remain intact. A squeeze of lemon juice can also brighten up the dish. For convenience, you can use dried herbs, but be mindful that they may burn at higher temperatures.
If you're looking for a more complex flavour profile, consider using a combination of herbs and spices. For example, you can create Ranch Potatoes by using a packet of dry Ranch seasoning. You can also toss your potatoes with cooked, crumbled bacon for a savoury twist.
Don't be afraid to experiment and find the combinations that suit your taste preferences. The possibilities are endless when it comes to adding herbs and spices to your air-fried potatoes!

Reheating and storing
If you have any leftover potatoes, you can store them in an airtight container in the refrigerator for up to 4-5 days. To freeze, seal the potatoes in an airtight container or freezer bag and store them in the freezer for up to 6-8 months.
When you're ready to enjoy your potatoes again, reheat them in the air fryer to restore their crispy texture. If your potatoes are frozen, thaw them overnight before reheating. Preheat your air fryer to 400°F and place the potatoes inside in a single layer. Reheat for 5-6 minutes, or until they are warm and crispy.
For best results, ensure your potatoes are not overcrowded in the air fryer, as they need space for the air to circulate and crisp effectively. You can also give the potatoes a shake or stir halfway through the reheating process to ensure even cooking.
Additionally, consider boiling your potatoes in an alkaline solution of baking soda and water before tossing them into the air fryer for reheating. This step helps break down the outer layer of the potatoes, creating a starchy coating that enhances the crispiness during the reheating process.
