Gluten-Free Air-Fryer Onion Rings: A Crunchy Delight

Making gluten-free onion rings in an air fryer is a tasty, healthier alternative to deep-fried onion rings. The process is simple and requires a handful of basic ingredients. First, slice a large yellow or white onion into rings. Next, set up three bowls: one with flour (gluten-free or regular), one with beaten eggs, and another with breadcrumbs (gluten-free or regular). Dip each onion ring into the flour, followed by the egg, and finally, coat it with the breadcrumbs. Place the onion rings in the air fryer basket in a single layer, spray with cooking oil, and air fry at around 370°F for 5-11 minutes, or until golden brown. Enjoy these crispy, gluten-free onion rings as a snack or appetizer!

Choosing the right type of onion

First, consider the flavour profile you want to achieve. Different types of onions offer varying levels of sweetness, pungency, and mildness. White onions, known for their sharp and pungent flavour, can add a distinct kick to your onion rings. On the other hand, yellow onions provide a nice balance between sharp and sweet flavours, becoming even sweeter the longer they're cooked. So if you're looking for a milder taste that will complement the crispy coating, yellow onions are an excellent choice.

Sweet onions, such as Vidalia, Texas, Maui, or Walla Walla, are also a popular choice for onion rings. Their flavour is softer and sweeter, with less of the astringent onion bite. Red onions are similar in flavour to yellow onions but are slightly milder, so they can be a good option if you want a hint of onion flavour without overwhelming the other ingredients.

When selecting your onions, it's important to consider their size. Choose larger onions to make cutting and coating easier. Look for onions with firm, dry skins that are free from sprouting or mould. Avoid onions with soft spots or signs of decay.

Additionally, you'll want to make sure your onions are fresh. Fresh onions should feel heavy for their size, indicating their juiciness and high water content. Older onions tend to become lighter and drier, which can affect the texture of your onion rings.

Lastly, don't be afraid to experiment with different types of onions to find your favourite. While sweet onions and milder varieties are typically preferred for onion rings, you can certainly use yellow onions if you don't mind a stronger onion flavour. You could even try red onions for a unique twist on this classic side dish.

Remember, the type of onion you choose will depend on your personal preference and the specific flavour you want to achieve. So, get creative, and don't be afraid to try something new!

Gluten-free flour alternatives

• Oat flour: This flour is made by grinding whole-grain oats, which adds flavour to baked goods. It can be used to make a crispy, crunchy product. However, it may result in a chewier, crumblier texture. Oats and oat flour can be subject to gluten contamination, so always opt for certified gluten-free options.
• Almond flour: A grain- and gluten-free flour with a nutty flavour, almond flour is made from ground, blanched almonds. It can be substituted in a 1:1 ratio for regular or wheat flour. However, it has a higher calorie count due to its fat content.
• Buckwheat flour: Despite its name, buckwheat is gluten-free and provides a rich, earthy flavour. It works well in yeast and quick breads but tends to be crumbly due to its lack of gluten. Buckwheat flour is also rich in antioxidants and various vitamins and minerals.
• Sorghum flour: Sorghum flour is made from an ancient cereal grain with a mild, sweet flavour and a light colour and texture. It is often mixed with other gluten-free flours or used in small quantities. The sorghum grain is high in protein and fibre, which can help slow sugar absorption.
• Amaranth flour: With an earthy, nutty flavour, amaranth flour can replace up to 25% of wheat flour and is ideal for making tortillas, pie crusts, and bread. It is rich in fibre, protein, and various micronutrients.
• Teff flour: Teff is the world's smallest grain, and its flour has traditionally been used to make injera, an Ethiopian bread. Teff flour can substitute for 25–50% of wheat or all-purpose flour and is high in protein and fibre, which can aid weight loss and blood sugar management.
• Brown rice flour: This whole-grain flour has a nutty flavour and can be used to make a roux, thicken sauces, or breaded foods. It is high in protein and fibre, which can help lower blood sugar levels and reduce weight. Brown rice flour also contains various vitamins and minerals.
• Chickpea flour: Also known as garbanzo flour or gram flour, chickpea flour has a nutty taste and grainy texture. It is a good source of fibre and plant-based protein, which can help manage body weight and boost heart health.
• Coconut flour: Coconut flour has a mild coconut flavour and a light texture, making it suitable for baking breads and desserts. It absorbs more water than regular or almond flour, so less is needed. Coconut flour is a good option for those with nut and gluten allergies.

These gluten-free flour alternatives can be used individually or blended to create an onion ring batter that suits your taste and dietary needs.

Preparing the onions

Firstly, select one or two large onions, preferably yellow or white, and trim the ends. Peel off the skins and cut the onions into slices about 1/4 to 1/2-inch thick. Separate the slices into individual rings and set them aside.

Next, prepare a dredging station with three shallow bowls. In the first bowl, place some gluten-free flour. You can use almond flour, coconut flour, gluten-free all-purpose flour, or a gluten-free flour blend. The second bowl should contain beaten eggs. You can use whole eggs or just egg whites, depending on your preference. For a vegan option, you can replace the eggs with a mixture of nut milk and ground flaxseed. The third bowl should contain gluten-free breadcrumbs. You can use store-bought gluten-free breadcrumbs or make your own by blending gluten-free bread rolls or your favourite gluten-free bread products. For extra flavour, add seasonings like salt, pepper, garlic powder, onion powder, or paprika to the flour and breadcrumbs.

Now, it's time to coat the onion rings. Start by dipping each onion ring into the flour, making sure to coat all sides. Tap gently to remove any excess flour. Next, dip the onion ring into the egg mixture, allowing the excess to drip off. Finally, coat the onion ring with the breadcrumb mixture, using your fingers to press the crumbs onto the onion. Repeat this process for all the onion rings.

Once all the onion rings are coated, it's time to arrange them in the air fryer basket. Spray the basket with cooking oil or line it with foil to avoid a mess. Place each onion ring in the basket, leaving a little space between them. Don't overcrowd the basket, as this can lead to uneven cooking. You may need to cook the onion rings in batches.

The breading process

Firstly, prepare your flour, egg, and breadcrumb mixtures. For the flour mixture, combine gluten-free flour with any desired seasonings, such as salt, pepper, and mustard powder, in a shallow bowl. In a separate shallow bowl, whisk your eggs with a fork; you can also add milk to this mixture if desired. Finally, prepare your breadcrumbs by combining gluten-free breadcrumbs with seasonings like paprika, chili powder, garlic powder, salt, and pepper in another bowl. You can also add grated parmesan to your breadcrumbs for an extra cheesy kick.

Now it's time to start breading! Dip each onion ring first into the flour mixture, making sure to coat all sides evenly. Gently shake off any excess flour. Next, dip the floured onion ring into the egg mixture, allowing any excess to drip off. Finally, coat the onion ring with the breadcrumb mixture, using your fingers to press the crumbs onto the onion. Repeat this process for each onion ring until they are all evenly coated.

If you want an extra crispy texture, you can double-dip your onion rings. Simply repeat the process by dipping the breaded onion ring back into the egg mixture and then into the breadcrumbs again for a thicker, crunchier coating.

Cooking in the air fryer

Now that you have your ingredients ready, it's time to cook your gluten-free onion rings in the air fryer! Here's a step-by-step guide:

• Prepare the Air Fryer: Preheat your air fryer to a temperature between 360-390°F (around 200°C). The ideal temperature may vary slightly depending on your air fryer model and preferences for crispiness.
• Prepare the Onions: Slice your onions into rings. For a large onion, cut them into 1/2-inch-thick slices. Separate the slices into individual rings.
• Set Up Your Dredging Station: This is where you'll coat your onion rings with the dry and wet ingredients. You'll need three shallow bowls. In the first bowl, place your flour of choice (gluten-free flour, almond flour, coconut flour, or regular flour). You can also add seasonings like salt, pepper, paprika, or garlic powder to this bowl. In the second bowl, whisk together your eggs and milk (or a milk alternative). In the third bowl, add your breadcrumbs (gluten-free or regular). If you're feeling adventurous, you can also add some grated parmesan cheese to this bowl for an extra crunchy and cheesy kick.
• Dredge the Onion Rings: This is the fun part! Take each onion ring and dip it first in the flour, making sure to coat all sides. Then, dip it in the egg mixture, letting the excess drip off. Finally, coat it thoroughly with the breadcrumbs. Repeat this process for all your onion rings.
• Transfer to the Air Fryer: Place each coated onion ring into the air fryer basket, making sure they are in a single layer and not overcrowded. You may need to cook them in batches. Spray the onion rings with cooking oil to help them crisp up.
• Cook the Onion Rings: Air fry your onion rings for about 5 minutes on each side, flipping them halfway through. The total cooking time may vary depending on your air fryer and desired level of doneness, but aim for a golden brown colour and a crispy texture.
• Serve and Enjoy: Remove the onion rings from the air fryer and transfer them to a serving platter. These gluten-free onion rings are best enjoyed fresh and hot. You can serve them with various dipping sauces, such as ranch, ketchup, honey mustard, vegan ranch, or creamy chipotle sauce.

Your gluten-free onion rings are now ready to be devoured! Enjoy the crispy, crunchy, and delicious treat you've created in your air fryer.
