Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Yellow or Sweet Onions: Slice into ½-inch rings for the perfect balance of sweetness and bite.

Almond Flour: A great low-carb alternative to regular flour, adding a nutty flavor and crispy coating.

Crushed Pork Rinds: The secret ingredient for that authentic crunch—use plain or lightly salted.

Parmesan Cheese: Adds savory depth and helps the coating turn beautifully golden.

Eggs: Help the coating stick to the onion rings.

Heavy Cream or Unsweetened Almond Milk: Mixed with eggs to help bind the coating.

Paprika and Garlic Powder: Add flavor and a touch of smokiness.

Salt and Black Pepper: Enhance and balance the overall taste.

Avocado Oil or Olive Oil Spray: For air frying or baking to achieve that crisp, golden finish.

Directions

1. Prepare the onions. Peel and slice the onions into ½-inch thick rings. Separate them carefully and pat dry with paper towels.
2. Set up your dredging station.
   • In one bowl, whisk together eggs and heavy cream.
   • In another, combine almond flour, crushed pork rinds, Parmesan, paprika, garlic powder, salt, and black pepper.
3. Coat the onion rings. Dip each onion ring first into the egg mixture, then into the dry mixture, pressing gently to adhere the coating. Place coated rings on a parchment-lined tray.
4. Choose your cooking method:
   • Air Fryer: Preheat to 375°F (190°C). Spray the basket with oil, arrange onion rings in a single layer, and air fry for 8–10 minutes, flipping halfway through. Spray lightly with oil if needed for extra crispiness.
   • Oven: Preheat to 425°F (220°C). Place the coated onion rings on a wire rack set over a baking sheet. Bake for 15–18 minutes, flipping halfway through, until golden and crisp.
5. Serve. Let them cool slightly, then serve warm with your favorite keto-friendly dipping sauce like spicy mayo, ranch, or sugar-free ketchup.

Yellow or sweet onions provide the perfect balance of flavor.
