Dijon Swordfish Steaks: A Culinary Symphony

The first time I tasted swordfish prepared with Dijon mustard was at a small seaside bistro in Marseille. The briny air, the gentle clinking of sailboats in the harbor, and that tangy, perfectly seared fish… It was pure magic. The Dijon cut through the richness of the swordfish, the herbs de Provence sang of the Mediterranean sun, and I knew I had to recreate that experience at home. This recipe is my humble attempt to capture that magic, bringing a taste of the French coast to your kitchen.

Recipe Overview

• Prep Time: 35 minutes
• Cook Time: 12 minutes
• Total Time: 47 minutes
• Servings: 4
• Yields: 4 fillets
• Dietary Type: Pescatarian

Ingredients

• 4 (4 ounce) swordfish steaks
• Salt and pepper

For the Marinade:

• 3 tablespoons Dijon mustard
• 2 tablespoons soy sauce
• 2 tablespoons olive oil
• 1 tablespoon honey (optional)
• 3 garlic cloves, minced
• 1 tablespoon lemon zest
• 1 tablespoon lemon juice
• 1 tablespoon herbes de provence
• Salt and pepper

Equipment Needed

• Shallow baking dish
• Broiler pan
• Mixing bowl
• Whisk or fork

Instructions

1. Begin by preparing the marinade. In a mixing bowl, combine the Dijon mustard, soy sauce, olive oil, honey (if using), minced garlic, lemon zest, lemon juice, herbes de provence, salt, and pepper. Whisk thoroughly until all ingredients are well combined and the mixture is emulsified.
2. Reserve half of the marinade for basting during the cooking process. This ensures the fish stays moist and flavorful while broiling.
3. Place the swordfish steaks in a shallow baking dish. Pour the remaining marinade over the swordfish, ensuring each steak is well coated. Toss gently to distribute the marinade evenly.
4. Cover the baking dish with plastic wrap or a lid and refrigerate for at least 30 minutes. This allows the flavors to penetrate the fish. Marinating for longer (up to an hour) will enhance the flavor even more. Do not marinate for extended periods, as the acidity of the lemon juice and mustard can begin to “cook” the fish and affect its texture.
5. While the swordfish is marinating, preheat your broiler. Position an oven rack so that the top of the swordfish steaks will be about 4-6 inches from the broiler element.
6. Prepare your broiler pan by brushing it lightly with olive oil or coating it with cooking spray. This will prevent the swordfish from sticking to the pan. Using a broiler pan with slats allows excess fat to drip away, resulting in a healthier dish.
7. Remove the swordfish steaks from the refrigerator. Place them on the prepared broiler pan.
8. Broil the swordfish steaks on the highest rack level, basting with the reserved marinade every two minutes. This frequent basting keeps the fish moist and builds up layers of flavor.
9. Flip the swordfish steaks over after 6 minutes.
10. Continue cooking for another 6 minutes, basting that side every two minutes. The swordfish is done when it is opaque and flakes easily with a fork. The internal temperature should reach 145°F (63°C). Be careful not to overcook the swordfish, as it can become dry.
11. Serve immediately.

Expert Tips & Tricks

• Don’t over-marinate: While marinating is crucial for flavor, avoid doing it for more than an hour. The acid in the marinade can break down the delicate texture of the swordfish.
• Pat dry before searing: For a beautiful sear, pat the swordfish steaks dry with paper towels before placing them under the broiler. This removes excess moisture and helps the fish to brown evenly.
• Adjust the heat: Broilers can vary significantly. Keep a close eye on the swordfish and adjust the rack position or broiling time as needed to prevent burning.
• Add a touch of citrus: For an extra burst of freshness, squeeze a wedge of lemon over the cooked swordfish just before serving.

Serving & Storage Suggestions

Dijon Swordfish Steaks are incredibly versatile and pair well with a variety of sides. As suggested, this recipe goes beautifully with a Mediterranean Style Couscous Salad with Roasted Veggies. Grilled asparagus, roasted potatoes, or a simple green salad are also excellent choices.

To store leftovers, allow the swordfish to cool completely. Place it in an airtight container and refrigerate for up to 2 days. To reheat, gently warm the swordfish in a skillet over low heat or in a microwave. Reheating can sometimes dry out the fish, so consider adding a splash of olive oil or lemon juice to retain moisture. Freezing is not recommended, as it can significantly alter the texture of the swordfish.

FAQs (Frequently Asked Questions)

Q: Can I grill the swordfish instead of broiling it?
A: Absolutely! Grilling is a fantastic alternative. Preheat your grill to medium-high heat and grill the swordfish for about 4-5 minutes per side, or until cooked through.

Q: What is the best way to tell if the swordfish is cooked?
A: The easiest way is to insert a fork into the thickest part of the steak and gently twist. If the fish flakes easily and is opaque throughout, it’s done. An internal temperature of 145°F (63°C) also indicates doneness.

Q: Can I use a different type of fish?
A: Yes, you can substitute other firm, meaty fish like tuna or mahi-mahi. Cooking times may vary slightly depending on the thickness of the fish.

Q: Can I make the marinade ahead of time?
A: Yes, the marinade can be made up to 24 hours in advance and stored in the refrigerator. This allows the flavors to meld together even further.

Q: Is it necessary to baste the swordfish while broiling?
A: Basting is highly recommended as it keeps the swordfish moist and adds flavor. The reserved marinade is perfect for this.
