Note

If using frozen fish fillets, ensure they are completely thawed and patted dry before baking to ensure even cooking.

You can substitute the Cheddar cheese with Gruyre or Parmesan for a different flavor profile.

For a gluten-free version, use gluten-free flour for the roux and gluten-free breadcrumbs for the topping.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently to prevent the fish from becoming rubbery.

Adjust the amount of hot sauce based on your preferred level of spiciness.
