What Makes These Keto Air Fryer Onion Rings Special?
Traditional onion rings are made with wheat flour, breadcrumbs, and often dipped in batter before being deep-fried. That process makes them high in carbs and unhealthy fats—two things that don’t align with the keto diet.
But our keto-friendly version uses low-carb substitutes like almond flour and pork panko (or crushed pork rinds), along with an air fryer to achieve that same golden crunch—with far fewer calories and zero guilt.
Here’s why these keto air fryer onion rings stand out:
- Low in carbs : Perfect for staying within your daily keto macros.
- High in healthy fats : Almond flour and olive oil provide beneficial fats.
- Crispy without frying : The air fryer gives you that satisfying crunch using little to no oil.
- Quick and easy : Ready in under 30 minutes with minimal prep work.
- Great for meal prep : Make a big batch and enjoy leftovers later.
Ingredients You’ll Need
To make keto air fryer onion rings, gather the following ingredients:
For the Coating:
- 1 large yellow onion
- 1/2 cup almond flour
- 1/4 cup crushed pork rinds (pork panko)
- 1 tsp garlic powder
- 1 tsp paprika
- 1/2 tsp salt
- 1/2 tsp black pepper
- 1 egg (for the egg wash)
Optional Dipping Sauces:
- Sugar-free ranch dressing
- Spicy mayo (mix mayonnaise with hot sauce)
- Keto ketchup (store-bought or homemade)
- Garlic aioli
Step-by-Step Instructions
Step 1: Prep the Onions
Start by slicing the yellow onion into 1/2-inch thick rings. Separate each ring and set aside. Try to get uniform slices for even cooking.
Tip: Soak the onion rings in cold water for 10–15 minutes to reduce their sharpness and bitterness. Dry thoroughly before proceeding.
Step 2: Set Up Your Breading Station
Create three bowls:
- Bowl 1: Whisk one egg with a tablespoon of water to create an egg wash.
- Bowl 2: Combine almond flour, garlic powder, paprika, salt, and pepper.
- Bowl 3: Place the crushed pork rinds (or pork panko).
Step 3: Bread the Onion Rings
Working one ring at a time:
- Dip the onion ring in the egg wash, ensuring it’s fully coated.
- Then dredge it in the almond flour mixture, pressing gently so it sticks.
- Finally, coat it in the pork rinds, again pressing to help the crumbs adhere.
Place the breaded rings on a plate and repeat until all are done.
Step 4: Air Fry the Onion Rings
Preheat your air fryer to 375°F (190°C) .
Place the onion rings in the air fryer basket in a single layer, not overlapping. Lightly spray or brush them with avocado oil or olive oil for extra crispiness.
Air fry for 8–10 minutes , flipping halfway through, or until golden brown and crispy.
Tip: Don’t overcrowd the basket. Cook in batches if needed to ensure even browning.
Step 5: Serve and Enjoy
Serve immediately while hot and crispy. Pair with your favorite keto dipping sauces for added flavor.
