Author Notes: This was so good, Sconeman and I ate it standing at the kitchen counter after I snapped the picture. - mrslarkin

Serves 2

  • 4 tablespoons unsalted butter, softened
  • 1/2 to 1 tablespoon Dijon mustard (smooth, not grainy)
  • one 1-inch-thick swordfish steak (about 1 lb.)
  • Sea salt
  • fresh cracked black pepper
  • 1/2 cup dry vermouth
  • 1/8 cup finely chopped shallot
  • 1 tablespoon unsalted butter
  • 1/2 tablespoon olive oil
  • 2 tablespoons coarsley chopped fresh tarragon
  1. Mash softened butter and mustard until smooth. Chill.
  2. Season fish on both sides with salt and pepper.
  3. Preheat oven to 400 degrees F.
  4. In a small saucepan, combine vermouth and shallot. Over high heat, bring to a boil and reduce to about 1/4 cup, about 5 minutes. Turn the heat down to very low and add the mustard butter, a tablespoon at a time, whisking after each addition until butter is incorporated. Keep sauce warm.
  5. Heat an oven-proof pan to medium-high. Add 1 tablespoon butter and olive oil. Place fish in pan and cook until nicely browned on the bottom, about 1 1/2 to 2 minutes. Carefully flip fish and place pan in the oven. Roast the fish for about 10 minutes, or until done.
  6. Stir the chopped tarragon into the sauce. Spoon sauce over warm plate. Lay fish on top of sauce. Serve with lemon wedges. Enjoy!

Hi,

Whole Foods has harpoon-caught swordfish which, they explained, is sweeter than swordfish caught other ways. And it is! The combination of your sauce and method with this fish is unbelievably delicious, even in this heat. Thank you so much. I encourage anyone who likes swordfish to try harpoon-caught.

Thanks so much, MSTC! I got my fish from New Wave Seafood in Stamford, CT, closer for me than WF.
