  • 4 boneless salmon
  • 5 sprigs of fresh dill (separated)
  •  1 tsp white wine
  •  1 tsp garlic powder
  • 2 tsp Italian spices
  • 2 tsp white pepper
  • 8-ounce salted butter (at room temperature, 25°C)

  • Scoop the compound butter into a plastic wrap. Then place it in your refrigerator and freeze for about four hours to two days.
  • Preheat your oven to about 450°F.
  • Spray your baking sheet with cooking spray or line it with a non-stick foil to ensure your salmon fillets don’t stick to the baking sheet.
  • Place your salmon fillets on the foil. Sprinkle some white pepper and Italian spices on it.
  • Carefully lay a sprig of fresh dill on each salmon piece.
  • Transfer the frozen Milanese compound butter into a small bowl. Shape into golf-sized balls.
  • Place these ball-shaped Milanese compound butter on top of the fresh dill on your salmon.
  • Back to your oven, place the salmon Milano in it, and bake at 350°F for about ten minutes.
  • Your salmon Milano is ready when it flakes slightly in the middle (you can test this by pressing the fish’s center with a knife)
