• 1/2 cup super-fine almond flour

Method

 

1. Prep onions: Peel onions and slice into 1/2-inch rounds. Separate into rings.Pat dry to remove moisture.

4. Coat: Dip each ring in the egg wash, let excess drip, then press into the crumb mixture. Pack crumbs on for even coverage.
5. Rest the rings: Place coated rings on a rack or tray and let sit 5–10 minutes.This helps the crust set.
6. Air fryer method: Preheat to 375°F (190°C) for 3 minutes. Spray basket and rings lightly with avocado oil. Cook in a single layer for 7–9 minutes, flipping halfway, until deep golden and crisp.

5. Rest the rings: Place coated rings on a rack or tray and let sit 5–10 minutes.

   This helps the crust set.

7. Oven method: Preheat to 425°F (220°C).

Storage Instructions

• Fridge: Store cooled rings in an airtight container for up to 3 days, with parchment between layers.
• Reheat: Air fry at 350°F for 3–5 minutes or bake at 400°F for 6–8 minutes until re-crisped.
• Freeze: Freeze in a single layer, then transfer to a bag.

  Reheat from frozen in the air fryer at 360°F for 6–8 minutes.

Health Benefits

• Low carb: Swapping breadcrumbs for almond flour and pork rinds cuts carbs dramatically.
• Higher protein and healthy fats: Parmesan and eggs add protein; almond flour brings vitamin E and good fats.
• Baked or air-fried: You get crunch with far less oil than deep frying.
• Onion goodness: Onions offer antioxidants and prebiotic fiber to support gut health.

Pitfalls to Watch Out For

• Too thick slices: Overly thick rings can steam and soften the crust. Stick to 1/2 inch.
• Skipping the rest: Letting coated rings sit helps prevent the breading from falling off.
• Overcrowding: Air fry or bake in a single layer for even crisping.
• Coating too coarse: Crush pork rinds very fine for better adhesion and uniform crunch.

Variations You Can Try

• Buffalo kick: Add 1/4 teaspoon cayenne to the coating and serve with blue cheese dip.
• Herb and cheese: Mix in 1 teaspoon Italian seasoning and swap Parmesan for Pecorino.
• Ranch-spiced: Add 1 tablespoon dry ranch mix to the crumb blend.
• Smoky BBQ: Stir in 1 teaspoon chipotle powder and a pinch of sweet paprika.
• Serve with: Pair with a crowd-pleasing main like these Crack Burgers Your New Go To Burger Recipe, or keep your air fryer going with crunchy sides like Crispy Air Fryer Zucchini Chips and salty-sweet Air Fryer Apple Chips With Cinnamon.

FAQ

Can I make these dairy-free?

Yes. Skip the Parmesan and use unsweetened almond milk in the egg wash.

Add an extra tablespoon of almond flour to the crumb mix to balance texture.

What can I use instead of pork rinds?

Use more almond flour plus 1–2 tablespoons of ground golden flaxseed for added crunch. Note: you’ll lose a bit of that “fried” flavor pork rinds give.

Why did my coating fall off?

Moisture is the usual culprit. Pat onions dry, do a light dry dredge before the egg, press crumbs on firmly, and let coated rings rest before cooking.

Which onion is best?

Sweet onions give you that diner-style bite, but yellow onions hold up well and have great flavor.

Avoid very mild white onions, which can go watery.

How do I keep them crispy for serving?

Hold finished rings on a wire rack in a 200°F oven. Avoid stacking, which traps steam and softens the crust.
