Peel and slice the onion width-wise in half-inch-thick rings. Break apart the larger rings and remove the small center parts for other preparations.
Set 3 bowls side by side, the first one containing the almond flour mixed with coconut flour, the second with the egg and whipping cream mixture (whisked together), and the third with the crushed pork rinds.
Dip the onion rings into the almond-coconut flour and coat. Transfer to the egg wash, take to the pork rinds, then go back to the egg mixture and return to the pork rinds again for extra breading and crispier results.
Place the onion rings on a greased Air Fryer basket. May need to cook in batches depending on the size of the air fryer. Cook for 15 minutes at 425ºF (200ºC)until they are crispy but tender inside. They should not brown too much on this process unless you spray a little cooking spray before air frying it.
Sprinkle with salt if desired. Serve with low-carb ketchup, ranch dressing, or other dips.
