Soak potatoes in cold water to prevent them from sticking together
Soaking potatoes in cold water is an effective way to prevent them from sticking together when cooking with an air fryer without oil. This method releases and removes excess starch from the potatoes, which is key to keeping them from sticking to one another. It also helps to achieve a crispier texture.
To do this, peel and chop your potatoes into roughly half-inch pieces and place them in a large bowl. Cover them with cold water and let them soak for around 20 minutes. Then, drain the potatoes, rinse them with cold water, and pat them dry with a clean dish towel. It is important to ensure that the potatoes are thoroughly dried before placing them back into a dry bowl and adding the remaining ingredients.
For best results, it is recommended to take the time to soak and rinse your potatoes before cooking. This extra step will help to ensure your potatoes are crispy and prevent them from sticking together. It is also important to cut your potatoes as evenly as possible for even cooking. Half-inch cubes work well and will crisp up nicely.
Additionally, while cooking, remember to shake your air fryer basket or stir the potatoes regularly to prevent sticking. This is especially important when cooking without oil, as food can burn quickly.

Shake the basket a few times to prevent food from sticking
When cooking with an air fryer, shaking the basket a few times is an important step to prevent food from sticking. Air fryers work by circulating hot air around the food at high speed, cooking it from all sides. This process can cause food to stick to the basket or to each other if not disturbed. By shaking the basket, you can redistribute the food and ensure even cooking on all sides.
For best results, it is recommended to shake the basket or stir the contents a few times during the cooking process. This is especially important when cooking without oil, as oil can act as a natural lubricant and help prevent sticking. Depending on the model of your air fryer, it may beep to remind you to shake the basket halfway through the cooking time. However, when cooking without oil, you may need to shake the basket a few extra times to prevent sticking.
The frequency with which you need to shake the basket depends on the type of food you are cooking and the desired level of crispiness. For example, when cooking potatoes, it is recommended to shake the basket or stir the potatoes every 5 to 15 minutes to prevent them from sticking and to achieve even cooking. Soaking potatoes in cold water before cooking can also help release excess starch and prevent sticking, resulting in crispier potatoes.
In addition to shaking the basket, using a spatula or spoon to stir the food can also help prevent sticking. It is important to note that air fryers cook food faster than traditional ovens, so it is crucial to keep an eye on your food to prevent burning. By following these tips and techniques, you can effectively use an air fryer without oil and still achieve delicious and crispy results.

Use spray oil instead of spreading oil on the tray
While it is possible to cook in an air fryer without using any oil, some people prefer to use a little oil to enhance the taste and texture of their food. If you are going to use oil, it is recommended to use a spray oil instead of spreading oil on the tray. This is because the oil can drip through the bottom of the basket and cause smoke. Spray oil is also more convenient and helps to ensure that the oil is evenly distributed.
When using spray oil, it is important to use it sparingly. A light spritz of oil on the food or the tray is usually sufficient. It is also a good idea to shake the basket a few times during cooking to prevent sticking, even when using oil.
Some people prefer to use a specific type of spray oil, such as olive oil or a commercial product like PAM. Others simply use a small amount of their favourite oil in a spray bottle.
In addition to using spray oil, there are a few other things to keep in mind when cooking with an air fryer. First, it is important to cut your food into even pieces to ensure even cooking. Second, be sure to remove the basket and shake or stir the contents a few times during cooking to prevent sticking. Finally, keep in mind that air fryers can cook food quickly, so it is important to keep an eye on your food to prevent burning.
