  • 2 teaspoons fresh rosemary, minced
  • 2 teaspoons fresh chives. minced
  • 2 teaspoons thyme, minced
  • 2 teaspoons lemon zest
  • 1 teaspoon kosher salt
  • 1/4 teaspoon red pepper flakes
  • 24 ounces swordfish steaks ( 4 - 6 ounces, 1 inch thick)
  • 1 tablespoon extra virgin olive oil
  • kosher salt
  • ground black pepper

  1. FOR THE HERB BUTTER: Combine all the ingredients in a food processor or beat with a mixer until well combined. Form butter into a log and roll tightly in plastic wrap. Refrigerate until firm.
  2. FOR THE SWORDFISH: Preheat your grill to med/high heat. Rub the oil on both sides of the fish and season well with salt and pepper on both sides. Grill the swordfish about 3-4 mins on each side.

Reserve the remaining butter for another use.
