What Makes These Keto Onion Rings Different from Classic Baked Onions?

Traditional onion rings are coated in flour and breadcrumbs, then deep-fried until golden. While delicious, they’re loaded with carbs and don’t fit into a keto lifestyle. These onion rings, on the other hand, are made with a cheese-based coating that crisps up beautifully in the oven or air fryer. Instead of greasy fried onions, you get baked onions wrapped in a crunchy, low-carb shell that pairs perfectly with your favorite dips. It’s one of the most clever twists on low carb keto recipes, and it proves that you don’t have to give up your favorite comfort foods while eating keto.

Ingredients for 2-Ingredient Keto Onion Rings

This recipe keeps things simple without sacrificing flavor or texture.

Fresh Onions for Perfect Rings

• 1 large onion (yellow or white work best; cut into thick rings)

Pantry Staples for Crispiness

• 1 ½ cups shredded mozzarella cheese (or a blend with cheddar for added flavor)

That’s it—just two ingredients for crunchy perfection! The cheese coating creates the crispy shell, while the onion provides sweetness and bite.

Step-by-Step Preparation of Crispy Keto Onion Rings

Making these onion rings at home couldn’t be easier. With only a few steps, you’ll have golden, crunchy rings ready in under 30 minutes.

Prepping the Onions Properly

Slice the onion into ½-inch thick rounds, then separate them into rings. Pat them dry with a paper towel—this helps the cheese stick better and prevents sogginess.

Coating the Onion Rings

Take each onion ring and press shredded cheese around it. The cheese should cling to the onion like a crust. If you like, you can season the cheese with paprika, garlic powder, or chili flakes before pressing it onto the onion.

Baking or Air Frying for Maximum Crunch

Preheat your oven to 400°F (200°C) or your air fryer to 375°F (190°C). Place the cheese-coated rings on a lined baking sheet or in the air fryer basket. Cook until the cheese melts and turns golden brown—about 15 minutes in the oven or 8–10 minutes in the air fryer. Allow them to cool slightly before serving, as the cheese coating crisps up more as it cools.
