- Egg whites: Acts as a binder, ensuring the coating adheres without adding carbs.

- Erythritol (optional): A touch of sweetness balances the savory notes if desired.
Complete Cooking Process
-
Ingredient Readiness:
Slice onions into even rings, pat dry, and set aside. Prepare the almond‑flour mixture with cheese and spices.

Flavor Development:
Dip each ring in beaten egg whites, then coat with the seasoned almond flour; the coating adheres while the egg sets.
-
Texture Control:
Arrange rings on a parchment‑lined sheet, leaving space so they bake evenly and stay crisp.
-
Finishing Touches:
Brush lightly with olive oil and bake until golden; a final sprinkle of flaky sea salt finishes the flavor.
-
Serving Timing:
Serve hot from the oven, paired with a cool dip like ranch or a squeeze of fresh lemon.
- Use a hot oven (425°F) for a true crunch.
- Dry onion rings thoroughly to avoid soggy coating.
- Flip halfway for even browning.
- Add a pinch of smoked paprika for extra depth.
