Ingredients & Their Roles

4 swordfish steaks (about 6 oz each, 1-inch thick) – The star of the dish, swordfish is meaty, mild, and takes well to marinades and grilling.
1/4 cup olive oil – Adds richness and helps the fish stay moist on the grill.

Juice and zest of 1 lemon – Brightens and balances the dish with acidity.
2 garlic cloves, minced – Provides bold, savory depth to the marinade.
1 tablespoon fresh parsley, chopped – Brings freshness and a subtle herbal flavor.

1 teaspoon dried oregano (or 1 tablespoon fresh) – Complements the fish with Mediterranean earthiness.
Salt and black pepper to taste – Essential for seasoning and enhancing the swordfish’s natural flavor.
Lemon wedges, for serving – Extra brightness at the table.

Step-by-Step Instructions

1. Prepare the Marinade

In a small bowl, whisk together olive oil, lemon juice and zest, garlic, parsley, oregano, salt, and pepper. Taste and adjust seasoning if needed.

2. Marinate the Swordfish

Place swordfish steaks in a shallow dish or zip-top bag. Pour marinade over the fish and turn to coat. Marinate for 15–30 minutes at room temperature. Avoid marinating for more than 30 minutes, as citrus can start to “cook” the fish.

3. Preheat the Grill

Heat your grill (gas or charcoal) to medium-high heat. Clean and oil the grates well to prevent sticking.

4. Grill the Swordfish

Remove swordfish from the marinade and let excess drip off. Grill for 4–5 minutes per side, depending on thickness, until the fish is opaque and grill marks appear. The internal temperature should reach 130–135°F, then rest to finish cooking.

5. Serve and Garnish

Transfer to a plate, rest for 2–3 minutes, and serve with lemon wedges and a sprinkle of fresh herbs if desired.
