Grilled Swordfish Steaks (Rhode Island Style) | Arteflame

Introduction

There is nothing quite like the aroma of sizzling garlic and bright lemon mingling with the salty sea air to transport you straight to the Rhode Island coast. This Grilled Swordfish is the epitome of summer dining—meaty, succulent steaks featuring a rugged, smoky char that gives way to a tender, buttery center. It is a dish that feels undeniably fancy yet rustic enough to eat on the back patio with friends, a glass of white wine in hand. The open fire of the grill amplifies the natural sweetness of the fish, creating a sensory experience you just can't get from a kitchen stove.

Why You'll Love This Catch

Swordfish is often called the "steak of the sea" for good reason; its firm texture holds up beautifully to the intense open fire of the Arteflame, making it much more forgiving than delicate flaky fish. This recipe strikes the perfect balance between the natural richness of the fish and the zesty kick of red pepper flakes in the lemon butter. It is a restaurant-quality meal that comes together in under 20 minutes, proving that gourmet seafood doesn't have to be intimidating.

Kitchen Wisdom

• Dry it well: Surface moisture creates steam, which prevents a good crust. Pat your steaks bone-dry with paper towels before seasoning.
• Watch the heat: Swordfish can go from juicy to dry quickly. Pull it off the grill at 130°F; the residual heat will carry it to perfection while it rests.
• Utilize zones: Use the center grate for the initial visual sear, then finish on the flat cooktop to bathe the fish in the butter sauce without flare-ups.

Simple Swaps

If you are dairy-free, swap the butter for high-quality olive oil or ghee; the garlic and lemon still shine through. For a milder flavor profile, trade the red pepper flakes for fresh cracked black pepper or fresh herbs like oregano.

Ingredients

The Fish

• 4 Swordfish steaks (approx. 1 inch thick, 6-8 oz each)
• 2 tbsp Extra virgin olive oil (for coating)
• Sea salt (to taste)
• Freshly cracked black pepper (to taste)

Rhode Island Lemon Butter Sauce

• 1/2 cup Unsalted butter
• 3 cloves Garlic, minced
• 2 tbsp Fresh lemon juice
• 1 tsp Red pepper flakes (adjust for heat)
• 2 tbsp Fresh parsley, chopped
• 1/2 tsp Paprika (for color and subtle depth)

Instructions

Step 1: Fire Up the Arteflame

1. Begin by building a fire in the center of your Arteflame grill. Use hardwood for the best flavor profile.
2. Allow the grill to burn down until you have a hot bed of coals and the flat steel cooktop reaches a consistent cooking temperature.
3. Lightly oil the flat cooktop to season it before placing any food down.

Step 2: Prepare the Swordfish

1. Remove the swordfish steaks from the refrigerator about 20 minutes before grilling to let them come to room temperature. This ensures even cooking.
2. Pat the steaks completely dry with paper towels. Surface moisture is the enemy of a good sear.
3. Rub each steak generously with olive oil, then season both sides with sea salt and black pepper.

Step 3: Make the Lemon Butter Sauce

1. Place a heat-safe sauce pot or small cast-iron skillet directly on the flat cooktop of the Arteflame.
2. Add the butter and let it melt completely.
3. Stir in the minced garlic and red pepper flakes. sauté for 1-2 minutes until fragrant but not browned.
4. Stir in the lemon juice, paprika, and chopped parsley. Move the pot to a cooler edge of the cooktop to keep warm without burning.

Step 4: The Sear and Cook

1. Place the swordfish steaks directly onto the center grill grate for a high-heat sear. Sear for about 2 minutes per side to get those beautiful grill marks.
2. Move the steaks onto the flat steel cooktop to finish cooking. This indirect heat is gentler and prevents the fish from drying out.
3. While on the flat top, brush the steaks generously with half of the lemon butter sauce.
4. Cook until the internal temperature reaches 130°F (medium) to 135°F. The flesh should be opaque and flake easily with a fork.

Step 5: Finishing Touches

1. Remove the steaks from the grill and let them rest for 3-5 minutes.
2. Pour the remaining warm lemon butter sauce over the steaks just before serving.
3. Garnish with extra parsley or lemon wedges if desired.

Tips for Success

Cooking swordfish requires a bit of attention because it has a lower fat content than salmon, meaning the line between perfectly juicy and dry is thin. The most critical tip for this recipe is to trust your meat thermometer. Pull the fish off the heat just before it hits your target temperature, as carryover cooking will raise it another 5 degrees while it rests. Additionally, utilizing the distinct heat zones of the Arteflame is your secret weapon. The center grate gives you the visual appeal and charred flavor, but finishing on the flat top ensures the steak cooks through evenly without scorching the exterior. Always ensure your grill surface is well-oiled; despite its meaty texture, swordfish can stick if the surface isn't properly prepped. If your steaks are thinner than an inch, reduce the cooking time significantly to preserve moisture.

Variations

While the traditional Rhode Island style leans heavily on lemon, butter, and pepper flakes, swordfish is a versatile canvas that welcomes creativity. You can easily adapt this recipe to suit different palate preferences or dietary needs without losing the essence of the dish. Here are a few ways to switch things up:

• The Caper Twist: Add 2 tablespoons of drained capers to the butter sauce for a briny, Mediterranean punch that pairs beautifully with lemon.
• Asian Fusion: Swap the butter for sesame oil and soy sauce, and replace the parsley with cilantro and fresh ginger.
• Herb Garden: If you prefer an herbaceous route, mix fresh oregano, thyme, and rosemary into the butter instead of red pepper flakes.
• Blackened Style: Before grilling, coat the fish in Cajun seasoning for a bold, smoky crust that complements the fire cooking.
• Dairy-Free: Substitute the butter with high-quality olive oil or ghee for a dairy-free version that still carries the garlic and lemon flavors well.

Best pairings

A dish as robust as grilled swordfish deserves sides that can stand up to its meaty texture and citrusy sauce without competing for attention. Since you already have the Arteflame fired up, it makes sense to utilize the flat top for your sides as well. The acidic nature of the lemon butter sauce calls for vegetables that have a bit of natural sweetness or starch to balance the palate.

• Grilled Asparagus: The charred tips of asparagus cooked on the flat top pair perfectly with the lemon sauce.
• Roasted Baby Potatoes: Slice them in half and roast them on the flat top with rosemary until crispy.
• Rice Pilaf: A light, fluffy rice pilaf absorbs the extra butter sauce on the plate beautifully.
• Arugula Salad: A fresh salad with a vinaigrette cuts through the richness of the butter.
• Drink Pairing: A crisp Sauvignon Blanc or a light Pinot Grigio complements the citrus notes, while a light lager works well for a casual backyard vibe.

Conclusion

Mastering Rhode Island-style grilled swordfish on your Arteflame is more than just cooking a meal; it is about embracing a lifestyle that values quality ingredients and the joy of outdoor cooking. The combination of the smoky char from the fire and the bright, spicy notes of the butter sauce creates a harmony of flavors that is truly memorable.
