Ingredients

  • 23 cup mayonnaise
  • 12 cup spicy brown mustard
  • 6 tablespoons fresh tarragon, chopped
  • 6 tablespoons fresh chives, chopped
  • 2 tablespoons brown sugar, packed
  • 2 tablespoons fresh lemon juice
  • 2 teaspoons lemon peel, finely grated
  • kosher salt
  • fresh ground black pepper
  • 3 12-3 34 lbs salmon, with skin about 1 1/2 inches thick

Method

  • Preheat oven to 450 degrees F and arrange rack in the center of the oven; line a baking sheet with parchment.
  • In a medium bowl, combine mayonnaise, mustard, tarragon, chives, sugar, lemon juice and lemon peel (everything but the salmon); season generously with salt and pepper.
  • Place salmon, skin side down, diagonally across the baking sheet; spoon 1/2 cup of the mustard sauce over top and spread so that it covers the salmon completely.
  • Season salmon with additional salt and pepper; roast until salmon is just opaque in the center, about 15 minutes.
  • Use the parchment paper to help you transfer the salmon to a serving platter; cut crosswise into serving pieces, and serve with remaining mustard sauce.
