Keto Onion Rings (Air Fryer Recipe)

Ingredients
- ½ whole white onion, peeled
- 2 cups pork rinds, finely crushed
- 2 eggs
- 1 tsp salt
- ½ tsp pepper
- ½ tsp paprika
- ½ tsp garlic powder
optional: 1/4 cup spicy mayo for dipping
Directions
- Peel and cut the onion in half.
- Cut slices lengthwise to create an onion ring shape and pop out the layers of onion within the onion ring.
- Mix the eggs in a shallow bowl until well combined.
- Place the pork rinds in a large ziplock bag and crush to a fine consistency.
- Add the seasonings into the pork rind crumbs and shake until well combined.
- Dip each onion ring piece into the egg wash and then place in the ziplock bag.
- Shake until the onion is evenly coated.
- Note: if you have a difficult time getting the crumbs to stick, try pressing them directly into the onion. If the pork rinds begin to clump and will no longer stick, you may have let too much egg into the bag. Start again with freshly crumbled pork rinds in a new bag.
- Place the onion rings in the air fryer at 380 degrees Fahrenheit for 6 minutes.
- Allow your keto onion rings to cool before serving with a side of your favorite keto condiment (we recommend spicy mayo).

Frequently Asked Questions
Are onion rings keto-friendly?
Traditional onion rings are typically coated in breadcrumbs, making them high in carbs. However, this keto version uses almond flour or coconut flour, significantly reducing the carb content while still delivering great flavor and crunch.
Can I use a different type of onion?
Yes, you can use different types of onions for your keto onion rings! While yellow or white onions are traditional, red onions offer a slightly sweeter flavor and a vibrant color. Sweet onions, like Vidalia, can also work well but may have a higher sugar content. For a milder taste, consider using shallots. Just keep in mind that cooking times may vary slightly based on the thickness and type of onion you choose. Experiment to find your favorite flavor!
How can I make my onion rings extra crispy?
To make your onion rings extra crispy, start by ensuring the onion slices are well-dried after soaking them in buttermilk or an egg wash. Use a combination of almond flour and grated Parmesan cheese for the coating; this adds flavor and crunch. Double-dip the rings by first coating them in the dry mixture, then dipping them back into the egg wash, and finally coating them again in the flour mixture. Before air frying, lightly spray the rings with cooking oil to promote crispiness. Cooking them at a higher temperature and in a single layer will also help achieve that perfect crunch!
