  • 1 teaspoon butter, or as needed

  • ¾ cup freshly grated Parmesan cheese

  • cup butter, softened

  • ¼ cup mayonnaise

  • ¼ cup chopped green onion

  • 3 tablespoons lemon juice

  • 2 teaspoons dried dill weed (Optional)

  • ¼ teaspoon salt

  • ¼ teaspoon ground black pepper

  • 2 dashes hot pepper sauce (such as Tabasco®)

  • 2 pounds cod fillets


  1. Set an oven rack about 6 inches from the heat source and preheat the oven's broiler. Line a baking sheet with aluminum foil; lightly coat with 1 teaspoon butter.

  2. Mix together Parmesan, 1/3 cup butter, mayonnaise, green onion, lemon juice, dill, salt, black pepper, and hot sauce in a medium bowl until well combined. Set aside.

  3. Lay cod fillets in a single layer on the prepared baking sheet.

  4. Cook under the preheated broiler until fish flakes easily with a fork, 7 to 8 minutes. Gently spread Parmesan mixture over fish; return to the oven and broil until topping is bubbly and lightly browned, about 2 more minutes.
