How to make Filet-o-Fish Copycat
Tips from the cook
- Blend the panko with the seasoning to a finer crumb, so the coating is thin and even.
- Keep the oil at 165 °C, not hotter, so the fish cooks through before the crust darkens.
- Do not crowd the pan, as the oil temperature drops.
- Drain the fish on a wire rack, so the underside stays crisp.
