This guide covers everything you need to know, from selecting the best onions to expert tips for achieving your desired texture.

⭐ Essential Air Fryer Onions Ingredients

To prepare these delightful air fryer onions, you’ll need just a few basic ingredients:

• One Sweet Onion: Approximately 8 ounces (227 grams). Sweet onions are highly recommended for their mild flavor and natural sugars, which caramelize beautifully.
• One Tablespoon Olive Oil: Or any other high smoke-point cooking oil you prefer, such as avocado oil or grapeseed oil. The oil is crucial for achieving that desirable texture and preventing the onions from drying out.
• Salt: To taste. A simple seasoning that enhances the onion’s natural sweetness.

While this recipe keeps it simple, feel free to get creative with your seasonings! Consider adding Italian seasoning, garlic powder, onion powder, black pepper, or even Everything Bagel seasoning for an extra flavor boost. Just be mindful to avoid seasoning blends that contain added sugar, as this can easily lead to burning and alter the cooking time in the air fryer.

The quantity of onions you use will impact the cooking time; a smaller batch will cook faster and more evenly. While yellow, red, or white onions can be used, sweet onions remain the top choice for their superior caramelization potential. Their inherent sweetness becomes pronounced under the air fryer’s heat, offering a truly delectable experience.

This recipe is adaptable to most air fryer models, including popular brands like Ninja Foodi, Philips, Nuwave, Pampered Chef, Actifry, Instant Pot Vortex, Cosori, and Breville. However, remember that cooking times can vary slightly between different appliances. Always keep a close eye on your onions, especially during the first few attempts with a new air fryer, to ensure perfect results.

🧅 How to Air Fry Onions: Step-by-Step Guide

Follow these simple instructions to prepare your perfect batch of air fryer onions:

2

Season and Load: Place the thinly sliced onions into a medium-sized bowl. Drizzle them generously with your chosen oil and sprinkle with salt to taste. Toss the onions gently to ensure they are evenly coated. Next, spread the seasoned onions in a single layer (as much as possible) in your air fryer basket or on an air fryer tray. Don’t worry if there’s some overlap; onions shrink considerably as they cook, making more space in the basket.

Now, let’s get ready to cook them down to perfection!

️⏲️ How Long to Cook Onions in the Air Fryer for Every Texture

3

For Lightly Sautéed Onions: Air fry your seasoned onions at 350°F (177°C) for a total of 12 minutes. Ensure you stir the onions thoroughly after approximately 10 minutes of cooking to promote even browning and prevent sticking. This duration will yield tender, lightly sautéed onions that are soft and sweet, perfect for adding a foundational flavor to many dishes.

For Golden Brown Onions: If you desire a deeper golden hue and slightly more softened texture, reduce the air fryer temperature to 300°F (150°C) and continue to air fry for an additional 5-10 minutes. Keep a close watch during this stage, stirring occasionally, to prevent burning and achieve that perfect golden color.

For Crispy Onions: To achieve wonderfully crispy air fryer onions, extend the cooking time at 300°F (150°C) beyond 10 minutes. Continue cooking in 2-3 minute increments, stirring frequently, until the onions reach your desired level of crispness. They will become more brittle and develop a satisfying crunch. Remember that air fryers cook quickly, so constant monitoring is essential to avoid overcooking and burning.

It’s important to note that while air frying onions creates delicious results, it won’t produce the exact deep, slow-cooked caramelization you achieve on a stovetop. The air fryer’s rapid air circulation and dry heat tend to crisp up the onions more quickly, rather than allowing them to slowly break down and develop that intense, jam-like sweetness over a longer period. For truly traditional caramelized onions, the stovetop method might be preferred. However, for a fast, easy, and incredibly flavorful alternative that offers a fantastic balance of sweetness and texture, air frying is an excellent choice!

How do you air fry onions with no oil?

While it’s technically possible to cook onions in an air fryer without oil, it’s generally not recommended for optimal results. The oil plays a crucial role in preventing the onions from drying out too quickly and burning around the edges while remaining raw in the center. Oil helps achieve a more even cook and a better texture, transforming the onions into tender, golden, or crispy delights. Without oil, you risk ending up with unappetizingly dry, partially burnt, and still-raw onion pieces.

How do you cook a whole onion in the air fryer?

Recipes claiming to cook a whole onion in the air fryer often fall short, as a large whole onion typically won’t soften thoroughly or cook evenly through its many layers in the air fryer’s environment. Unless you’re dealing with small pearl onions, which can be air-fried whole with success, it’s best to stick to air frying chopped or sliced onions. This ensures uniform cooking, better texture, and a more enjoyable eating experience.

How do you dehydrate onions in an air fryer?

You can indeed dehydrate onions in an air fryer by setting it to its lowest temperature. While this method can be quicker than using a dedicated food dehydrator, it comes with a few caveats. You’ll need to stir the onions much more frequently – every 15-20 minutes – to ensure even drying and prevent scorching. Additionally, air fryers are typically designed for smaller batches, so you’ll be limited to dehydrating a very small amount of onions at a time compared to a full-sized dehydrator.

How long can you store crispy fried onions without a freezer or fridge?

Air fryer crispy fried onions should not be left at room temperature for more than 2 hours. Unlike commercially produced crispy fried onions, which undergo extensive dehydration and often contain preservatives, homemade air-fried onions retain more moisture. This higher moisture content means they are much more susceptible to bacterial growth and spoilage if not refrigerated promptly. Always prioritize food safety and refrigerate any leftovers.
