Swordfish With Orange Basil Butter: A Mediterranean Kiss

My first encounter with swordfish was during a summer internship at a small trattoria nestled along the Amalfi Coast. The aroma of the sea mingled with the bright citrus groves, and the simple, yet profound, flavors of Italian cooking became etched in my memory. This Swordfish with Orange Basil Butter recipe captures the essence of that experience – the sun-drenched flavors, the freshness of the ingredients, and the effortless elegance of Italian cuisine. It’s a dish that transports me back to that vibrant coastline with every bite.

Recipe Overview

• Prep Time: 10 minutes
• Cook Time: 10 minutes
• Total Time: 20 minutes
• Servings: 4
• Dietary Type: Pescatarian, Gluten-Free

Ingredients

• 2 tablespoons olive oil
• ¾ cup orange juice
• 2 tablespoons orange juice
• ¼ cup chopped fresh basil
• 4 swordfish steaks
• ¼ teaspoon salt
• 8 tablespoons (1 stick) butter, softened
• 1 orange, zested

Equipment Needed

• Broiler
• Small bowl
• Whisk or fork
• Plate
• Plastic wrap

Instructions

1. In a bowl, combine the olive oil, ¾ cup of the orange juice, pepper (optional, to taste), and ¼ of the chopped fresh basil.
2. Brush each side of the swordfish steaks generously with the orange-basil mixture.
3. Place the marinated swordfish on a plate, cover tightly with plastic wrap, and refrigerate for at least 1 hour. This allows the flavors to penetrate the fish, resulting in a more flavorful and tender final product. You can marinate for up to 2 hours for a more intense flavor.
4. Preheat your broiler. Position an oven rack so that the top of the swordfish steaks will be about 3-4 inches from the broiler element.
5. Remove the swordfish from the refrigerator and season each steak with salt.
6. Broil the swordfish, turning once halfway through, for a total of 8-10 minutes, or until the fish is cooked through and flakes easily with a fork. The exact cooking time will depend on the thickness of your steaks and the strength of your broiler, so keep a close eye on them. The internal temperature should reach 145°F (63°C).
7. While the swordfish is broiling, prepare the orange basil butter. In a small bowl, beat the softened butter until light and fluffy.
8. Add the remaining chopped fresh basil, the orange zest, and the 2 tablespoons of orange juice to the softened butter.
9. Beat the ingredients together until just combined. Be careful not to overmix, as this can cause the butter to become oily.
10. Serve the hot swordfish steaks immediately with a generous dollop of the cold orange basil butter on top. The contrast between the warm fish and the cool butter is delightful.

Expert Tips & Tricks

• Doneness is Key: Swordfish is best when cooked just until it’s opaque and flakes easily. Overcooking will result in a dry, tough steak. Use a meat thermometer to ensure perfect results every time.
• Broiler Positioning: The distance between the fish and the broiler is crucial. Too close, and the fish will burn on the outside before it’s cooked through. Too far, and it will take too long to cook, drying it out.
• Butter Temperature: Make sure your butter is properly softened before you begin. This will allow it to incorporate the other ingredients more easily and create a smooth, creamy sauce. Take the butter out of the refrigerator about 30-60 minutes before you plan to make the recipe.
• Flavor Infusion: For an even more intense orange flavor, add a teaspoon of orange zest to the marinade along with the juice.
• Pan-Seared Option: If you don’t have a broiler, or prefer to pan-sear the fish, simply heat a tablespoon of olive oil in a heavy skillet over medium-high heat. Cook the swordfish for 4-5 minutes per side, or until cooked through.

Serving & Storage Suggestions

Serve the Swordfish with Orange Basil Butter immediately for the best flavor and texture. The cold orange basil butter melts slightly over the hot fish, creating a delicious sauce. This dish pairs perfectly with a side of roasted asparagus, a simple green salad, or some creamy risotto.

Leftover swordfish can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet over low heat or in the microwave. The orange basil butter can also be stored in the refrigerator for up to 3 days. Let it soften slightly before serving. Freezing is not recommended, as it can affect the texture of the fish.

Variations & Substitutions

• Lemon Basil Butter: Substitute lemon zest and lemon juice for the orange zest and orange juice for a brighter, tangier flavor.
• Herb Variations: Feel free to experiment with other fresh herbs, such as thyme, rosemary, or chives, in place of the basil.
• Spicy Kick: Add a pinch of red pepper flakes to the marinade for a touch of heat.
• Other Fish: If you can’t find swordfish, this recipe also works well with tuna, mahi-mahi, or halibut. Adjust the cooking time accordingly based on the thickness of the fish.
• Dairy-Free Option: Substitute the butter with a plant-based butter alternative to make this recipe dairy-free.
• Citrus Burst: Add a few segments of fresh orange or grapefruit to the plate for a beautiful presentation and an extra burst of citrus flavor.

FAQs (Frequently Asked Questions)

Q: Can I marinate the swordfish for longer than 1 hour?
A: Yes, you can marinate the swordfish for up to 2 hours. Marinating it for a longer period will allow the flavors to penetrate deeper, resulting in a more flavorful steak. However, avoid marinating it for longer than 2 hours, as the acid in the orange juice can start to break down the fish.

Q: Can I use dried basil instead of fresh basil?
A: Fresh basil is highly recommended for this recipe as it provides a brighter, more vibrant flavor. If you must use dried basil, use about 1 teaspoon in the marinade and 1 teaspoon in the butter.

Q: How do I know when the swordfish is done cooking?
A: The swordfish is done when it is opaque and flakes easily with a fork. The internal temperature should reach 145°F (63°C). Avoid overcooking the fish, as it will become dry and tough.

Q: Can I grill the swordfish instead of broiling it?
A: Absolutely! Grilling the swordfish adds a smoky flavor that complements the orange basil butter beautifully. Preheat your grill to medium-high heat and grill for 4-5 minutes per side, or until cooked through.

Q: Can I make the orange basil butter ahead of time?
A: Yes, you can make the orange basil butter up to 2 days in advance. Store it in an airtight container in the refrigerator. Let it soften slightly before serving.
