Ingredients
Scale
- 2 to 4 swordfish steaks, about 1-inch thick (6–8 oz or 170–225 g each)
- 2–3 sprigs fresh rosemary, finely chopped (or 1 teaspoon dried rosemary)
- 1 large lemon, zested and juiced
- 3 tablespoons extra virgin olive oil
- 2 cloves garlic, minced
- 1 teaspoon sea salt (preferably coarse kosher salt)
- ½ teaspoon freshly ground black pepper
- Optional: pinch of red pepper flakes
Instructions
- Prepare the marinade by whisking together olive oil, lemon juice and zest, minced garlic, chopped rosemary, sea salt, black pepper, and optional red pepper flakes in a mixing bowl.
- Pat swordfish steaks dry with paper towels and coat evenly with the marinade. Let rest at room temperature for 15-20 minutes.
- Preheat grill to medium-high heat (about 400°F or 205°C) and lightly oil the grates.
- Grill swordfish steaks for 4-5 minutes per side until opaque with grill marks and firm but springy to the touch.
- Check doneness with a meat thermometer aiming for 130°F (54°C) for medium doneness.
- Transfer steaks to a plate, tent loosely with foil, and rest for 5 minutes.
- Serve immediately garnished with extra lemon wedges and fresh rosemary or parsley.
Notes
Do not marinate swordfish for longer than 20 minutes to avoid the lemon juice ‘cooking’ the fish. Use a meat thermometer to avoid overcooking; aim for 130°F (54°C). Rest the fish after grilling to keep it juicy. If no grill is available, use a grill pan or broil in the oven. Pat fish dry before marinating for a better sear.
