How to cut onions for an air fryer

Onions are a versatile ingredient that can be used in a variety of dishes. They can be cooked in an air fryer, which is a healthier alternative to traditional sautéing as it uses little to no oil.

To cut onions for an air fryer, start by setting up your workstation. You will need a cutting board and a sharp knife. It is recommended to place a glass of water next to your cutting board to prevent tears from the onion vapours. Alternatively, you can wear goggles to protect your eyes.

Next, select the type of onion you want to use. You can use any variety of onion, such as yellow, white, red, or sweet onions. Keep in mind that yellow onions are great for sweetness, red onions add extra flavour, and white onions have a bit more bite. Choose onions that are large in size, as they are easier to slice evenly, which helps them cook uniformly.

Now, let's get to cutting! First, cut off the top of the onion and peel back the outer skin and layer, discarding them. Then, cut the onion in half lengthwise, from root to stem. Place the onion cut-side down on the cutting board, and make thin slices from the stem end to the root end. Try to make the slices as evenly sized as possible, about 1/4" to 1/2" thick. If you prefer thicker slices, you may need to increase the cooking time in the air fryer.

Once you have sliced all the onions, you are ready to season and cook them in the air fryer!

Oil and seasoning for air fryer onions

Air fryer onions are a versatile dish that can be used as toppings or in salads, sandwiches, tacos, fajitas, burritos, and rice or grain bowls. They can also be served as a side dish or added to vegetables to make fajitas.

To make air fryer onions, you will need a large onion, a tablespoon of oil, and seasoning. You can use any type of onion, but larger onions are preferable as they give you more to work with and make it easier to get evenly sized slices. The type of oil is also up to you; olive oil and avocado oil are good options as they cook well at high temperatures.

• Peel the onion and slice it into thin wedges or strips. The slices should be of medium thickness—too thin, and they may burn; too thick, and they may not caramelize well.
• In a shallow bowl, mix together your choice of seasonings to ensure they are well blended. You can omit the seasonings, but at a minimum, it is recommended to use salt and black pepper.
• Place the sliced onions in a large bowl and drizzle with oil. Toss the onions until they are well-coated.
• Add the seasonings to the bowl and toss the onions until they are coated.
• Place the seasoned onions in the air fryer basket, spreading them out as much as possible.
• Preheat your air fryer to 370°F or 375°F and cook the onions for 10-12 minutes, turning them halfway, or until they are golden brown. For a lighter version, you can skip the oil, but the onions may turn out drier.

Some popular seasoning options for air fryer onions include:

• Garlic powder
• Smoked paprika
• Italian herbs
• Balsamic vinegar
• Cayenne pepper
• Brown sugar
• Cajun seasoning
• Red pepper flakes
• Onion powder

Air fryer temperature and time for cooking onions

Air fryer onions are a quick and easy recipe that can be used as toppings or ingredients for a variety of dishes. The temperature and time for cooking onions in an air fryer depend on the desired texture and type of onion used.

For crispy onions, slice the onions thinly and cook at 350°F (177°C) for 12 minutes, stirring after 10 minutes. Then, lower the temperature to 300°F (150°C) and cook for an additional 5-10 minutes. This will give you golden brown onions. For even crispier onions, you can extend the cooking time slightly.

If you prefer softer, more caramelized onions, you can cook the onions at 370°F (187°C) for 15-20 minutes, stirring halfway through. For more caramelized onions, you can add a splash of water, broth, balsamic vinegar, or butter and continue cooking for another 5-10 minutes.

It's important to note that cooking times may vary depending on the type of air fryer and the thickness of the onion slices. Larger onions and thicker slices may require a longer cooking time, while thinner slices may cook faster. Additionally, different types of onions, such as red, white, or yellow, may have slightly different cooking times due to their varying firmness and moisture content.

Air fryer onions are a versatile and delicious addition to burgers, sandwiches, tacos, fajitas, soups, salads, and more. They can be made with minimal ingredients and are a healthier alternative to traditional sautéed onions, as they require less oil.

How to store leftover air fryer onions

Air fryer onions are a delicious addition to any meal, and it's good to know that you can store leftover air fryer onions for later use! Here are some tips on how to store them to keep them fresh and crispy:

Firstly, allow the onions to cool completely after cooking. This is an important step to prevent condensation from building up in the storage container, which can make the onions soggy. Once the onions are cooled, transfer them to an airtight container. This helps keep the onions crisp, as exposure to air can make them lose their crunch over time.

You can store the leftover onions in the refrigerator for up to a week. Keeping them in a single layer within the container will also help maintain their crispiness, and it is best to avoid stacking them to prevent sogginess. If you want to keep them for longer, consider freezing them. Spread them out in a single layer on a baking sheet and freeze until solid, then transfer them to a freezer-safe bag or container.

When you're ready to enjoy your leftover onions, simply reheat them in the air fryer for a few minutes until they're crispy again. It is best to reheat them in the air fryer as this will help retain their crispy texture. So, the next time you have leftover air fryer onions, don't throw them away—store them and enjoy them later!
