Serves: 4 // Prep time: 15 minutes | Grilling time: 18 to 20 minutes

Grocery List

Fresh Produce

  • .25 oz fresh mint
  • 2 jalapeño chile peppers
  • 2 lemons
  • 2 scallions

Meat / Poultry / Seafood

  • 4 swordfish steaks, each about 8 oz and 1" thick

Oil and Spices

  • 2 tbsp extra-virgin olive oil
  • .25 tsp freshly ground black pepper
  • 1 tsp kosher salt


  • .5 cups unsalted butter


  • 2 medium jalapeño chile peppers
  • ½ cup (1 stick) unsalted butter
  • ¼ cup minced fresh mint leaves (from 8 to 10 sprigs)
  • 3 tablespoons fresh lemon juice
  • 2 scallions (white and light green parts only), thinly sliced
  • 1 teaspoon kosher salt, divided
  • 4 swordfish steaks, each about 8 ounces and 1 inch thick
  • Extra-virgin olive oil
  • ¼ teaspoon freshly ground black pepper
  • 4 lemon wedges


  1. Prepare the grill for direct cooking over medium heat (350° to 450°F).

  2. Brush the cooking grates clean. Grill the jalapeños over direct medium heat, with the lid closed, until blackened, about 10 minutes, turning occasionally. Place the jalapeños in a bowl and cover with plastic wrap to trap the steam. Let stand for about 10 minutes. Peel away and discard the charred skin, stems, and seeds, and then finely dice.

  3. In a small saucepan over medium heat, cook the butter until melted and frothy. Mix in the jalapeños, mint, lemon juice, scallions, and ½ teaspoon of the salt. Keep warm over very low heat.

  4. Brush the swordfish steaks on both sides with oil and season evenly with the remaining ½ teaspoon salt and the pepper. Grill over direct medium heat, with the lid closed, until just opaque in the center but still juicy, 8 to 10 minutes, turning once.

  5. Top the swordfish steaks with jalapeno-mint butter sauce and serve warm with lemon wedges.

Awesome Swordfish Recipe

Grilled the 1.25 lb swordfish piece on a Weber Performer at 350 for 10 minutes. Used hickory chunks to add some smoke. The sauce kicked it up a level! Great sauce and grilled flavor combination!

A great combination of flavours. The jalapeno / mint / butter / lemon really brings out the flavour of the fish. a clear winner.
