Grilled Bluefish Steaks (Delaware Style) | Arteflame

Introduction

Imagine biting into a steak that sizzles with a crispy, golden crust while the inside remains impossibly moist and savory. That is the magic of fresh Bluefish. For years, I shied away from this "aggressive" game fish, but once I threw it on the high heat of my Arteflame, I was converted. The smoky char perfectly cuts through the natural oils, creating a seaside feast that feels both rustic and refined. It’s the kind of meal that demands a cold drink and good company on a warm summer evening.

Why This Recipe Works

Bluefish is often misunderstood, but this Delaware-style preparation changes the game. The secret lies in the mustard and vinegar marinade. It’s a bold, zesty counterpoint that tames the fish's richness without masking its distinctive flavor. Plus, it’s incredibly forgiving on the grill—unlike delicate white fish, bluefish holds its shape beautifully, making it a stress-free option for your next backyard cookout.

Kitchen Wisdom

• Pat it dry: Moisture is the enemy of a good sear. Use paper towels to get the fish bone-dry before marinating to ensure that perfect crust.
• Trim the line: For a milder taste, carefully slice away the dark red bloodline running through the center of the fillet before cooking; this reduces the "fishy" intensity significantly.

Make It Your Own

If you can't find Bluefish, fresh Mackerel is a great oily alternative that loves high heat. No red wine vinegar? Apple cider vinegar works beautifully for a slightly sweeter tang.

Ingredients

• 4 fresh Bluefish steaks (approximately 8 oz each, 1-inch thick)
• 1/2 cup extra virgin olive oil
• 1/3 cup red wine vinegar
• 2 tablespoons Dijon mustard
• 3 cloves garlic, minced finely
• 1 tablespoon fresh oregano, chopped (or 1 tsp dried)
• 1 tablespoon fresh parsley, chopped
• 1 teaspoon sea salt
• 1/2 teaspoon freshly ground black pepper
• Lemon wedges (for garnish and serving)
• Vegetable oil or melted butter (for coating the grill cooktop)

Instructions

Step 1: Prepare the Fish

1. Rinse the bluefish steaks under cold water and pat them completely dry with paper towels. This is crucial for getting a good sear.
2. Inspect the steaks for the dark red bloodline running through the meat. While edible, removing this strip can significantly reduce the "fishy" intensity. Use a sharp knife to carefully trim this away if you prefer a milder flavor.

Step 2: Create the Delaware Marinade

1. In a medium mixing bowl, whisk together the olive oil, red wine vinegar, and Dijon mustard until the mixture emulsifies and becomes creamy.
2. Stir in the minced garlic, chopped oregano, parsley, sea salt, and black pepper.
3. Place the bluefish steaks in a shallow glass dish or a resealable plastic bag. Pour the marinade over the fish, ensuring every steak is generously coated.
4. Refrigerate for at least 30 minutes, but no longer than 1 hour. Bluefish texture can become mushy if left in acid for too long.

Step 3: Fire Up the Arteflame

1. Start a wood fire in the center of your Arteflame grill. Allow it to burn down until you have a bed of hot coals and the flat cooktop griddle is very hot.
2. The center of the cooktop will be the hottest (perfect for searing), while the outer edges are cooler.
3. Lightly coat the cooktop surface with vegetable oil or a little melted butter to ensure a non-stick surface.

Step 4: Grill the Steaks

1. Remove the steaks from the marinade and let the excess drip off. Do not rinse them.
2. Place the steaks directly onto the hot flat cooktop. You want to hear an immediate sizzle.
3. Grill for about 4 to 5 minutes on the first side. Do not try to move the fish too early; let a crust form so it releases naturally from the metal.
4. Carefully flip the steaks using a metal spatula. Grill the second side for another 3 to 5 minutes. The fish is done when it is opaque and flakes easily with a fork, or reaches an internal temperature of 145°F.

Step 5: Rest and Serve

1. Remove the steaks from the grill and place them on a serving platter.
2. Let them rest for 2 to 3 minutes to allow the juices to redistribute.
3. Squeeze fresh lemon juice over the hot steaks immediately before serving to brighten the flavors.

Tips

Grilling bluefish requires a bit of strategy to ensure the best flavor and texture. First and foremost, freshness is paramount. Bluefish degrades faster than most other species, so try to cook it within 24 hours of catching or purchasing. If the fish smells overly strong before cooking, soaking the steaks in milk for 30 minutes prior to marinating can help neutralize the odor. When using the Arteflame, utilize the different heat zones. If your steaks are particularly thick, sear them near the center for a minute or two, then slide them toward the cooler outer ring to finish cooking through without burning the exterior. Finally, because bluefish is an oily fish, it is very forgiving on the grill and won't dry out as quickly as snapper or flounder, but keep a close eye on it to avoid overcooking the delicate flakes.

Variations

While the classic Delaware-style preparation relies on mustard and vinegar, bluefish is a versatile canvas for bold flavors. You can easily adapt this recipe to suit different global palates without changing the cooking method. The strong natural flavor of the fish pairs exceptionally well with aggressive spices and glazes. Here are a few ways to switch up your next cookout:

• Cajun Blackened: Skip the wet marinade and coat the steaks in a dry rub of paprika, cayenne, garlic powder, and onion powder before searing with butter.
• Asian Fusion: Replace the vinegar and mustard with soy sauce, grated ginger, sesame oil, and a touch of honey for a sweet and savory glaze.
• Mediterranean Citrus: Use lemon juice instead of vinegar and add capers and chopped Kalamata olives to the finished dish.
• Spicy Mayo Topping: Instead of a marinade, spread a thin layer of mayonnaise mixed with Sriracha on the fish before grilling; it creates a rich, golden crust.
• Herb Butter Finish: Grill the fish simply with oil, salt, and pepper, then top with a compound butter made of dill, chives, and lemon zest while hot.

Best pairings

Because bluefish is rich and oily, the best side dishes are those that provide a crisp, acidic, or starchy contrast to balance the palate. Avoid heavy, cream-based sides that might make the meal feel too greasy. Fresh vegetables and bright salads are your best friends here. In Delaware, it is traditional to serve this fish with summer staples that highlight the local harvest. Consider these options to round out your meal:

• Acidic Salads: A vinegar-based coleslaw or a cucumber and onion salad with dill provides the perfect crunch and tang to cut through the fish's richness.
• Grilled Vegetables: Since your Arteflame is already hot, throw on some asparagus, corn on the cob, or zucchini slices seasoned with lemon pepper.
• Potatoes: Salt-boiled new potatoes with parsley butter or crispy grilled potato wedges offer a satisfying starch that absorbs the savory juices.
• Beverages: Pair with a crisp, high-acid white wine like Sauvignon Blanc or a cold, hoppy IPA to cleanse the palate between bites.
