The low carb version of a classic comfort food, Keto Onion Rings are a great appetizer, or side dish! Onion rings are classically made by dipping the onions in flour or breadcrumbs, then deep-frying them, which results in a crunchy, carb-rich coating. But this keto version replaces the carb-y coating with almond flour, coconut flour, or pulverized pork rinds to keep them crunchy while low-carbing. Perks of low carb keto onion rings: They’re super versatile — fry them up for that golden crunch or bake/air-fry them for a lighter version.
They are a perfect appetizer, snack or side to burgers, grilled meats or salads. Of course, these onion rings are delicious, and they are full of fiber and nutrients coming from onions so you can have the best of both worlds without the carbs! Their satisfying crunch combined with a creamy dipping sauce (ranch, sugar-free ketchup, or garlic aioli, anyone?) makes them too good to pass up. Whether you’re serving a crowd, or just craving a delicious crunch, these keto onion rings a quick and easy treat that pack a punch when it comes to taste without breaking the carb bank. They are evidence that you don’t have to say goodbye to your beloved comfort foods when eating keto!
