Grilled Swordfish with Salmoriglio Sauce

by

If you are looking for a vibrant, Mediterranean-inspired meal that feels elegant yet takes less than 20 minutes to prepare, Swordfish with Salmoriglio is an absolute must-try. Salmoriglio is a classic Sicilian condiment crafted from extra-virgin olive oil, fresh lemon juice, garlic, oregano, and parsley.

When spooned over hot, seared or grilled swordfish, this bright herb sauce cuts through the rich, steak-like texture of the fish, delivering an unforgettable burst of sunny coastal Italian flavor.

Why Salmoriglio is the Ultimate Seafood Sauce

While swordfish is hearty enough to handle bold seasonings, light citrus-and-herb dressings bring out its natural sweetness without overpowering it:

  1. Emulsified Heat & Flavor: Whisking warm water or lemon juice into good extra-virgin olive oil creates a light sauce that coats the hot swordfish immediately after grilling.
  2. Herb Balance: The pairing of fresh oregano and parsley adds an earthy, peppery brightness that complements the garlic and red pepper flakes.

Complete Ingredient List

To make this Sicilian swordfish recipe, gather the following ingredients:

  • Fish: 4 swordfish steaks (approx. 6 oz each), about 1 inch thick
  • Grilling Oil: 2 tbsp olive oil (for brushing)
  • Seasoning: Fine sea salt and freshly cracked black pepper to taste

Sicilian Salmoriglio Sauce

  • Olive Oil: ⅓ cup extra-virgin olive oil
  • Citrus: 3 tbsp fresh lemon juice, plus extra lemon wedges for serving
  • Garlic: 2 garlic cloves, finely minced
  • Herbs:
    • 1 tbsp fresh oregano leaves (or 1 tsp dried oregano)
    • 2 tbsp fresh flat-leaf parsley, finely chopped
  • Spice & Seasoning: Pinch of red pepper flakes, sea salt to taste

Expanded Step-by-Step Cooking Instructions

Step 1: Prepare the Salmoriglio Sauce

In a small bowl, whisk together the extra-virgin olive oil, fresh lemon juice, minced garlic, fresh oregano, chopped parsley, red pepper flakes, and a pinch of salt. Whisk vigorously until the oil and lemon juice blend into a light, fragrant dressing. Set aside so the flavors meld together.

Step 2: Prep and Dry the Swordfish Steaks

Remove the swordfish steaks from the refrigerator 10 to 15 minutes before cooking. Pat both sides completely dry with paper towels. Brush both sides lightly with the 2 tablespoons of olive oil, and season generously with sea salt and black pepper.

Step 3: Grill or Sear to Perfection

Preheat your grill or a heavy indoor cast-iron grill pan over medium-high heat until lightly smoking. Carefully lay the swordfish steaks onto the hot grill surface. Grill undisturbed for 4 to 5 minutes per side, until deep grill marks form and the fish turns opaque throughout (reaching an internal temperature of 145°F / 63°C).

Step 4: Sauce and Rest

Transfer the grilled swordfish steaks immediately to a serving platter. Whisk the salmoriglio sauce once more, then spoon it generously over the hot swordfish steaks so the herbs melt into the fish as it rests for 2 minutes.

Step 5: Serve

Garnish with fresh lemon wedges on the side and serve immediately while hot.

Serving Suggestions & Storage Tips

  • Pairings: Serve hot alongside garlic-roasted baby potatoes, grilled zucchini, or a fresh Caprese salad.
  • Storage: Best enjoyed fresh. Leftovers can be stored in an airtight container in the refrigerator for up to 2 days.
  • Reheating: Reheat gently in a skillet over medium-low heat with a tiny splash of olive oil just until warmed through.
