Instructions

  1. Heat the oven to 425°F (220°C). Set a wire rack on a rimmed sheet pan and brush it with a little of the oil. (Air fryer: heat to 375°F / 190°C.)

  2. Peel the onion, trim the ends and cut it crosswise into ½-inch (1.25 cm) slices. Separate the rings and pick out the larger ones — about 20–24 — saving the small centers for another dish. Peel away the thin membrane inside each ring if it lifts off easily; the coating sticks better without it.

  3. Set up three shallow bowls: coconut flour mixed with half the salt; the eggs beaten with the cream; and the crushed pork rinds mixed with the parmesan, paprika, garlic powder, cayenne and remaining salt.

  4. One ring at a time, toss in the coconut flour and tap off the excess, dip in the egg and let the excess drip back, then press into the crumbs to coat all sides. For an extra-thick crust, dip it back into the egg and crumbs a second time. Lay the rings on the rack without touching.

  5. Brush or spray the rings lightly with the remaining oil. Bake 12–15 minutes, until deep golden and crisp and the onion is tender when pierced. Air fryer: cook in a single layer for 8–10 minutes, turning halfway.

  6. Serve right away with ranch or sugar-free ketchup for dipping.

Tips for success

  • Use one hand for the dry bowls and the other for the egg, so your fingers don't end up breaded too.
  • Crush the pork rinds as finely as you can — a food processor, or a zip-top bag and a rolling pin — so they cling like breadcrumbs. Keep a jar of pork rind "panko" on hand to make this even quicker.
  • An honest note on carbs: onions are a moderate-carb vegetable, so this recipe works out to about 55 g of onion per person. That portion is what keeps onion rings within keto limits.

Nice to have, not needed

  • A wire rack lets hot air reach the underside so the rings crisp all over — on bare parchment, flip them halfway.

Storage & meal prep

  • Keeps 1 day in the fridge
  • Doesn’t freeze well

Reheat: Re-crisp in a 375°F (190°C) air fryer or oven for 4–5 minutes — never the microwave.

Best eaten fresh. Refrigerate leftovers up to 2 days and re-crisp in a 375°F (190°C) air fryer or oven for 4–5 minutes.
