  • 6 tablespoons unsalted butter, softened

  • 2 tablespoons chopped basil

  • 2 teaspoons drained capers, chopped

  • 1 tablespoon plus 1 teaspoon fresh lemon juice

  • Salt and freshly ground pepper

  • 1 tablespoon extra-virgin olive oil

  • Four 8-ounce swordfish steaks, cut 1 inch thick

  • Arugula and endive salad with pine nuts and Parmesan, for serving


  1. Light a grill. In a small bowl, blend the butter with the basil, capers and 1 teaspoon of the lemon juice. Season with salt and pepper, and refrigerate.

  2. In a large, shallow dish, mix the olive oil with the remaining 1 tablespoon of lemon juice. Season the swordfish with salt and pepper and turn the fish in the olive oil mixture. Refrigerate for 15 minutes.

  3. Grill the swordfish steaks over a hot fire until nicely charred on the outside and just cooked within, about 4 minutes per side. Transfer the steaks to plates, top each with a dollop of basil-caper butter and serve right away, with the arugula and endive salad with pine nuts and Parmesan.

Make Ahead

The basil-caper butter can be refrigerated for up to 2 days.

Suggested Pairing

Flavored butter gives these meaty swordfish steaks a piquant, herbal taste that's echoed in Sauvignon Blanc, particularly ones from the Collio region of Italy.
