Tips
Pat fish very dry before seasoning to ensure better coating adherence and even cooking.
Spread mayo mixture on the cutting board before transferring to baking dish to minimize mess and ensure even coverage.
Broiler intensity varies; watch the topping closely during the final browning step to prevent burning.
Good to Know
Refrigerate leftover fish in an airtight container for up to 2 days. Not recommended for freezing due to mayo topping.
Mix mayo-Parmesan topping up to 2 hours ahead and refrigerate. Do not apply to fish until ready to bake.
Serve immediately while hot with steamed vegetables, rice, or a green salad.
Common Mistakes
Do not skip drying the fish to avoid soggy coating and uneven browning.
Do not crowd the baking dish to avoid steaming instead of baking.
Do not forget to watch broiler closely to avoid charring the topping.
