What You'll Learn
Air fryer temperature and timing
Air-frying onions is a quick and easy method to achieve crunchy, golden onions with minimal oil. The temperature and timing depend on the type of onion, the quantity, and the desired texture and colour.
For sliced onions, preheat the air fryer to 370°F (187°C). Toss the onions with olive oil and salt, and cook for 5 minutes, shaking the basket halfway through. For crispier onions, increase the cooking time and reduce the temperature slightly.
For onion rings, preheat the air fryer to 300°F (149°C). Toss the onion rings with oil, and place them in the basket. Fry for 10 minutes, stirring every 5 minutes. Then, reduce the temperature to 240°F (116°C) and continue frying until crispy and golden. This two-step process takes around 15-18 minutes in total at the lower temperature.
For thin half-moon slices, preheat the air fryer to 350°F (177°C). Drizzle the onions with oil and sprinkle with salt. Air fry for a total of 12 minutes, stirring after 10 minutes. For golden brown onions, lower the temperature to 300°F (150°C) and cook for an additional 5-10 minutes.
It is important to note that different air fryers may vary in temperature and cooking time, so it is essential to keep an eye on the onions and adjust the settings as needed. Additionally, stirring or shaking the basket at regular intervals ensures even cooking and prevents burning.

Onion preparation
To prepare onions for air frying, start by peeling a large onion and slicing it into rings or strips. You can use a sharp knife or a mandolin to cut the onion into thin, even slices. The recommended slice thickness varies depending on the source, with some suggesting a medium thickness to prevent burning, and others suggesting thin slices to promote even cooking. If you are making onion rings, trim one end of the onion and leave the other end intact to hold while slicing.
After slicing, toss the onions with oil and seasonings. You can use olive oil, avocado oil, or coconut oil, and season with salt and pepper. Other suggested seasonings include garlic powder, smoked paprika, Italian seasoning, and cayenne pepper.
Once the onions are prepared, preheat your air fryer to a temperature between 265F and 370F. Lightly spray the air fryer basket with oil, then add the onions to the basket. If your air fryer does not have a preheat function, simply add the onions to the basket and cook at the desired temperature.

Oil and seasoning
Oil is an important component of frying onions in an air fryer. It helps the onions to caramelize and become tender. You can use a variety of oils, such as olive oil, avocado oil, coconut oil, or cooking spray. The amount of oil used can vary, but it is generally recommended to use just enough to coat the onions lightly. You can drizzle, spray, or toss the onions with oil to ensure they are evenly coated.
When it comes to seasoning, the options are endless. Salt and pepper are the most commonly used seasonings, but you can also add garlic powder, smoked paprika, Italian herbs, balsamic vinegar, onion powder, or cayenne pepper for a spicy kick. You can also try Cajun seasoning or Vegeta all-purpose seasoning. These seasonings not only add flavor but can also enhance the color of the onions, making them more appealing.
It is important to note that the amount of seasoning used can vary according to taste preferences. Additionally, if you are using a pre-made seasoning blend, you may need to adjust the amount of salt and pepper added to the onions to avoid over-seasoning.
The versatility of air-fried onions is one of their greatest strengths. They can be used as a topping for burgers, sandwiches, salads, and pizzas, or as a side dish. They are also perfect for adding depth of flavor to soups, curries, and rice dishes.
In conclusion, oil and seasoning play a crucial role in the preparation of fried onions in an air fryer. By choosing the right type and amount of oil and experimenting with different seasonings, you can create delicious, crispy, and flavorful onions that can enhance a variety of dishes.

Storage
Storing your air-fried onions is a straightforward process. However, there are a few key steps to follow to ensure they stay fresh and crispy. Firstly, it is crucial to let the onions cool entirely before storing them. If you skip this step, the onions may "'steam'" and become soggy. Once cooled, transfer the onions to an airtight container. This will prevent moisture from getting in and keeping your onions crispy.
You can store the onions at room temperature in the airtight container for up to 4-5 days. If you wish to keep them longer, you can refrigerate them for up to two weeks. The cool temperature of the fridge will help prolong their freshness.
If you want to keep your fried onions for an even longer period, consider freezing them. Place the cooled onions in a freezer-safe bag and freeze them for up to 4-6 months. This method is ideal if you want to make a large batch of fried onions for future use.
When you're ready to use your fried onions, you can reheat them on the stove, in the oven, or even in the air fryer itself. If you're using the frozen onions, it's best to thaw them in the refrigerator overnight first. This will ensure they heat up evenly.
