Grilled Swordfish with Orange Zest (Massachusetts Style) | Arteflame

Introduction

Picture a warm coastal breeze and the scent of wood smoke mingling with bright citrus. That is exactly the mood this dish delivers. Swordfish is often called the "steak of the sea" for good reason—its dense, meaty texture sears beautifully without falling apart. One bite of this orange-zested steak takes me right back to summer vacations in Massachusetts, where seafood is always fresh and dinner is always served al fresco. It is elegant, effortless, and incredibly rustic.

Why It’s a Summer Favorite

I adore this recipe because it strikes the perfect balance between sophisticated dining and backyard ease. The marinade does double duty: the acid tenderizes the fish while the natural sugars create a gorgeous caramelization on the hot steel. It feels like a restaurant-quality meal, yet it comes together in under an hour. Plus, cooking on the Arteflame means no fear of fish sticking to grates or falling into the fire—just a perfect, even sear every time.

Kitchen Wisdom

• Watch the Clock: Swordfish is lean. Pull it off the heat the second it hits 140°F to keep it juicy; carryover cooking will do the rest.
• Hot Surface Required: Ensure your cooktop is scorching hot and well-oiled before the fish touches down to get that signature golden crust.

Swaps & Subs

No swordfish? Thick-cut mahi-mahi or even halibut steaks work wonderfully here. If you prefer a sharper bite over the sweetness of orange, simply swap the juice and zest for lemon or lime.

Ingredients

• 4 fresh Swordfish steaks (about 1 inch thick)
• 2 large Oranges (zested and juiced)
• 1/4 cup Extra Virgin Olive Oil
• 3 cloves Garlic, minced
• 1 tbsp Fresh Rosemary, chopped
• 1 tsp Sea Salt (plus more to finish)
• 1/2 tsp Freshly Cracked Black Pepper
• 1 Lemon (cut into wedges for serving)
• Fresh Parsley for garnish

Instructions

Step 1: Prepare the Marinade

1. In a small mixing bowl, whisk together the olive oil, fresh orange juice, minced garlic, chopped rosemary, salt, and black pepper.
2. Stir in the orange zest, reserving a small pinch for the final garnish.
3. Place the swordfish steaks in a shallow dish or a resealable plastic bag. Pour the marinade over the fish, ensuring each steak is thoroughly coated.
4. Let the fish marinate in the refrigerator for at least 30 minutes, but no longer than 1 hour. Because of the citrus acid, marinating too long can start to "cook" the fish and alter the texture.

Step 2: Fire Up the Arteflame

1. Build a wood fire in the center of your Arteflame grill. Allow the fire to burn down until you have a bed of hot coals and the cooktop reaches a high searing temperature.
2. Lightly oil the flat steel cooktop to ensure a non-stick surface. You want the surface hot enough that water droplets sizzle and evaporate immediately upon contact.

Step 3: Grill the Swordfish

1. Remove the swordfish from the marinade and let any excess liquid drip off. Do not rinse the fish.
2. Place the steaks directly onto the medium-hot zone of the plancha cooktop. You should hear an immediate, aggressive sear.
3. Cook for approximately 4 to 5 minutes on the first side. Resist the urge to move the fish; let the crust form, which will allow it to release naturally from the steel.
4. Flip the steaks and cook for another 3 to 4 minutes on the other side, or until the internal temperature reaches 145°F and the flesh is opaque and flakes easily with a fork.

Step 4: Rest and Serve

1. Remove the swordfish from the grill and place it on a serving platter.
2. Let the fish rest for about 3-5 minutes to allow the juices to redistribute throughout the meat.
3. Garnish with the reserved orange zest and fresh parsley. Serve immediately with lemon wedges on the side.

Tips for the Perfect Sear

Grilling swordfish requires a bit of attention to ensure it remains juicy rather than drying out. The most critical tip is to avoid overcooking. Swordfish has a low fat content compared to salmon, meaning it can go from succulent to tough very quickly. Use a digital meat thermometer to pull the steaks off the heat the moment they hit 140°F—carryover cooking will bring them to the USDA recommended 145°F while they rest. Additionally, utilizing the different heat zones on your Arteflame is a game-changer. Start the fish closer to the center fire to get that beautiful golden-brown crust, then move it further out to the cooler edge of the cooktop if the outside is browning too fast before the inside is cooked through. Finally, always ensure your cooktop is well-seasoned and oiled immediately before placing the fish down to prevent sticking.

Variations

While the orange zest and rosemary combination is a classic nod to Massachusetts coastal flavors, swordfish is a versatile canvas that accepts many different flavor profiles. If you don't have oranges on hand, or simply want to try something different, you can easily pivot this recipe to suit your palate. The meaty texture of the fish stands up well to bold spices and acids. Experimenting with different citrus fruits or adding a spicy kick can completely transform the dish while keeping the cooking method exactly the same. Here are a few distinct variations to try on your next cookout:

• Lemon-Caper Butter: Swap the orange for lemon and finish the grilled steak with a spoonful of melted butter, capers, and dill.
• Spicy Chili-Lime: Use lime juice and zest instead of orange, and add a teaspoon of red chili flakes or cayenne powder to the marinade.
• Asian Soy-Ginger: Replace the rosemary and salt with soy sauce, grated fresh ginger, and a dash of sesame oil for an umami-packed version.
• Mediterranean Style: Top the grilled fish with a relish made of chopped kalamata olives, diced tomatoes, and fresh basil.
• Blackened Swordfish: Skip the liquid marinade and coat the fish in a dry Cajun spice rub before searing on the Arteflame for a smoky, spicy crust.

Best Pairings

To create a balanced meal that highlights the citrus notes of the swordfish, you want sides that are light yet flavorful. Since you are already firing up the Arteflame, it makes sense to utilize the remaining surface area of the grill for your side dishes. Grilled vegetables are a natural choice as they pick up the same smoky nuance as the fish. You also want a beverage that cuts through the meatiness of the fish without overpowering the delicate orange zest. Think crisp, high-acid wines or light refreshing cocktails. Here are some of the best accompaniments to round out your table:

• Grilled Asparagus: Tossed in olive oil and lemon pepper, grilled right alongside the fish.
• Citrus Couscous: A light grain salad with cucumber and feta makes a fresh base for the steak.
• Sauvignon Blanc: The acidity and citrus notes of this wine mirror the marinade perfectly.
• Grilled Polenta Cakes: Crispy on the outside and soft on the inside, cooked on the flat top.
• Arugula Salad: A simple salad with a vinaigrette dressing provides a peppery bite that contrasts the sweet orange glaze.
