Ingredients

  • 4 mild white fish fillets (about 6 ounces each), like haddock, cod, halibut or tilapia
  • ¼ teaspoon kosher salt
  • ¼ teaspoon freshly ground black pepper
  • 3 tablespoons mayonnaise
  • 2 teaspoons Dijon mustard
  • 1 teaspoon cream-style horseradish
  • 1 tablespoon fresh lemon juice
  • 2 tablespoons grated Parmesan cheese divided
  • ¼ cup plain panko breadcrumbs
  • 1 tablespoon finely chopped fresh parsley (or 1 teaspoon dried parsley flakes)
  • 2 teaspoons olive oil
  • Lemon wedges optional for serving

Instructions

  • Preheat oven to 425°F. Line a rimmed baking sheet with parchment paper.
  • Pat the fish fillets dry with paper towels and place them on the prepared baking sheet. Season evenly with salt and pepper.
  • In a small bowl, combine the mayonnaise, Dijon mustard, cream-style horseradish, lemon juice, and 1 tablespoon of the Parmesan cheese.
  • In a second small bowl, combine the panko, parsley, olive oil, and remaining 1 tablespoon Parmesan.
  • Spread the Dijon mixture evenly over the top of each fillet. Sprinkle the breadcrumb mixture over the top and lightly press it into the coating to help it stick.
  • Bake for 12 to 15 minutes. The fish is done when it flakes easily with a fork and is opaque all the way through. If you have an instant-read thermometer, it should register 145°F in the thickest portion.
  • Serve with lemon wedges, if desired.

Notes

Storage: Store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently in a 350°F oven or air fryer until warmed through to help maintain the crisp topping.
