Grilled swordfish steaks with lemon and olive oil from Sicily's coast. This high protein mediterranean dish is fresh, lean, and ideal for a family dinner on a keto or dash diet plan.
Pat the swordfish steaks dry with paper towels and place them in a shallow dish.
Zest one lemon, then squeeze both lemons for juice; combine juice and zest with olive oil, salt, and pepper in a bowl and whisk until blended.
Pour the marinade over the swordfish, turning to coat. Cover and refrigerate for 20 minutes, but no more than 1 hour.
Preheat your grill to medium-high heat (about 450°F) and brush the grates with olive oil to prevent sticking.
Grill the swordfish steaks for 4–5 minutes per side, turning once; ensure the center is just opaque and firm for best flavor and texture, then transfer to a serving platter.
Sprinkle chopped fresh parsley and a generous squeeze of fresh lemon over the grilled fish and serve immediately.
