- 5 tablespoons unsalted butter, softened, divided
- 1/2 to 1 tablespoons 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
- 1/2 tablespoon olive oil
- 2 tablespoons coarsley chopped fresh tarragon
- Mash 4 tablespoons softened butter and mustard until smooth. Chill.
- Season fish on both sides with salt.
- Preheat oven to 400 degrees F.
- 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.
- 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.
- Stir the chopped tarragon into the sauce. Spoon sauce over warm plate. Lay fish on top of sauce. Season with pepper. Serve with lemon wedges.
