Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 8 minutes (per side, approximately)
• Total Time: 23 minutes
• Servings: 4
• Yield: 4 fillets
• Dietary Type: Gluten-Free (ensure wine is gluten-free)

Ingredients

• 4 swordfish fillets, 1 1/2 inches thick
• 2 tablespoons olive oil
• 2 teaspoons fresh rosemary, minced
• 1 tablespoon fresh parsley, minced
• 1/4 cup shallot, minced
• 1/3 cup dry white wine (such as Sauvignon Blanc or Pinot Grigio)
• 3 tablespoons lemon juice
• 2 tablespoons fresh lemon zest, grated
• 1/2 cup unsalted butter, cut into pieces
• 4 sprigs fresh rosemary, for garnish
• Salt, to taste
• Freshly ground black pepper, to taste

Equipment Needed

• A medium saucepan
• A whisk
• A grill or broiler
• Tongs
• Plates for serving

Instructions

1. Begin by preparing the exquisite white wine sauce. In a medium saucepan, combine the minced parsley, minced shallot, dry white wine, and lemon juice. Place the saucepan over medium-high heat and bring the mixture to a boil. Allow it to boil until the liquid has reduced to about 3 tablespoons, concentrating the flavors beautifully.
2. Once reduced, lower the heat to low. Stir in the 1/2 teaspoon of minced rosemary and the grated lemon zest.
3. Now, the magic of the sauce unfolds. Add the butter, piece by piece, whisking continuously to emulsize it into the wine mixture. Continue to add the butter until it is all incorporated and the sauce is rich, smooth, and glossy.
4. Remove the saucepan from the heat. Season the sauce with salt and freshly ground black pepper to your taste. Keep the sauce warm; a gentle simmer over very low heat or a brief period on a warm stovetop will suffice.
5. While the sauce is being kept warm, prepare the swordfish. Pat the swordfish fillets dry with paper towels – this is crucial for achieving a good sear. Sprinkle the swordfish fillets evenly with the remaining minced rosemary, salt, and freshly ground black pepper.
6. Heat your grill to medium heat, or preheat your broiler.
7. If grilling, place the seasoned swordfish fillets on the hot grill. Cook for approximately 3-4 minutes per side, or until the fish is cooked through and flakes easily with a fork. The exact time will depend on the thickness of your fillets and the heat of your grill.
8. If broiling, place the fillets on a baking sheet and broil about 4-6 inches from the heat source for 4-6 minutes per side, again, adjusting for thickness and broiler intensity.
9. Once cooked, remove the swordfish from the grill or broiler and let it set for several minutes before plating. This resting period allows the juices to redistribute, ensuring a moist and flavorful fish.
10. To plate, smear a small amount of the warm white wine sauce in the center of each plate. Carefully place a swordfish fillet on top of the sauce. Drizzle a generous spoonful of the remaining sauce over the top of each fillet.
11. Garnish each plate with a fresh sprig of rosemary for an aromatic and visual flourish. Serve immediately.

Expert Tips & Tricks

When selecting swordfish, look for fillets that are firm to the touch and have a clean, oceanic aroma. The thickness is key here; 1 1/2 inches allows for a beautiful sear on the outside while keeping the interior wonderfully moist and tender. Don’t be tempted to overcook swordfish, as it can become dry quickly. The visual cue of the flesh turning opaque and flaking easily with a fork is your best indicator of doneness. For an even deeper rosemary flavor in the sauce, you can lightly bruise the rosemary sprigs before adding them to the initial simmering stage, then remove them before adding the butter.

Serving & Storage Suggestions

This Rosemary White Wine Swordfish is best enjoyed immediately after preparation to appreciate its delicate flavors and textures. It pairs beautifully with simple accompaniments that won’t overpower the star of the show. Consider serving it with a light, crisp salad featuring seasonal greens and a citrus vinaigrette, or some steamed asparagus or green beans. For a more substantial meal, roasted new potatoes or a simple orzo pilaf would be excellent choices.

Leftovers, should there be any, can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently on the stovetop over low heat or in a covered oven at a low temperature (around 300°F/150°C) to avoid drying out the fish. The sauce can also be reheated separately and drizzled over the fish.

Variations & Substitutions

While swordfish is the star, this preparation is wonderfully versatile. If swordfish isn’t readily available, mahi-mahi or halibut would make excellent substitutes, though cooking times may need slight adjustment due to varying thickness. For a dairy-free option, you could experiment with a high-quality vegan butter substitute; ensure it has a neutral flavor profile. The white wine can be swapped for chicken broth or vegetable broth, though the nuanced flavor will be different. If fresh rosemary is scarce, use about half the amount of dried rosemary, being mindful of its more potent flavor.

FAQs

Q: Can I prepare the sauce ahead of time?
A: The sauce can be made a few hours in advance and kept warm over very low heat or gently reheated. It’s best to add the butter just before serving for the freshest emulsion.

Q: How do I know when the swordfish is cooked through?
A: The flesh should be opaque and flake easily with a fork. A quick way to check is to gently press the thickest part of the fillet; it should yield slightly and the flesh should separate easily.

Q: Is swordfish a sustainable choice?
A: Swordfish sustainability can vary by region. It’s always a good practice to check with your local fishmonger or consult seafood guides to make informed choices.

Q: What if I don’t have a grill or broiler?
A: You can pan-sear the swordfish fillets in a hot, oiled skillet over medium-high heat for about 4-5 minutes per side, until cooked through.

Q: Can I use other herbs instead of rosemary?
A: While rosemary is traditional, thyme or sage could also be lovely additions, offering a slightly different but equally delicious herbal note.
