Turn this classic diner side into an easy, low-carb, and crispy dish for your friends and family.
Supposedly invented in the UK during the early 1800s, the humble onion ring has become a culinary icon in the West. Bars, diners, and fast-food joints of all kinds have been crafting this easy-to-eat dish for generations. Typically, each succulent ring of white onion is dipped in batter or coated with breadcrumbs and deep-fried until golden brown. But this recipe uses almond flour and Parmesan to cater to those who are seeking fewer carbs and a fresher, nuttier flavor. With the same crispy outside and decadent inside, these keto onion rings are more than enough incentive to invest in an air fryer.
In fact, it’s the air fryer that makes this recipe fly by like a breeze with minimal mess. In just a few minutes, you’ll have a delightful appetizer to pass around with friends and family. Keto onion rings aren’t overly greasy like fast food versions, yet they’re even richer with flavor. With a coating enriched by egg, heavy cream, and Parmesan, these onion rings easily turn golden brown and leave you feeling more satisfied with each bite. This is definitely a dish I’d make at parties alongside pizza rolls, French fries, and other finger food classics. Who could say “no” to such a dippable, delicious, and fun way to eat onions?
What makes them “keto”?
The ketogenic diet is defined by low carbs, high fat and moderate levels of protein. Since these onion rings are breaded with almond flour instead of wheat flour, they fit both categories of ketogenic and gluten-free. So, if you or your loved ones are seeking a tasty comfort food that abides within either of these diets, you’ve come to the right place! And don’t worry—just because they’re “alternative,” doesn’t mean they aren’t still deliciously crispy and satisfying. This recipe was designed with your taste buds in mind!
How do I store leftovers?
Make sure your leftover onion rings have cooled completely to room temperature before transferring them to an airtight container. Refrigerate them for up to 3 days or freeze them for 1-2 months. Heat them up in the oven at 350°F for 10 minutes if frozen, or 5 minutes if from the fridge. The longer they cook, the crispier they’ll be, so feel free to keep them in for an extra minute or two if you like.
