Step-by-Step Instructions

Step 1: Preheat the Oven

Set your oven to 400°F (204°C). Line a rimmed baking sheet or shallow baking dish with parchment paper or lightly grease it with oil to prevent sticking.

Step 2: Prep the Swordfish Steaks

Pat the swordfish steaks very dry with paper towels. This step is key for a golden crust. Brush both sides with 1 tablespoon olive oil, then season generously with kosher salt and freshly ground black pepper.

Step 3: Make the Lemon-Garlic Oil

In a small bowl, combine the remaining 2 tablespoons olive oil, minced garlic, dried oregano, and lemon zest. Stir well, then spoon this mixture evenly over the top of each steak.

Step 4: Bake the Swordfish

Arrange the seasoned steaks on the prepared baking sheet. Bake in the center of the oven for 12–15 minutes, depending on thickness. Aim for about 10 minutes per inch of thickness. The fish should turn opaque and flake easily with a fork.

Step 5: Rest and Finish

Remove from the oven and let the swordfish rest for 3–5 minutes. Just before serving, drizzle with fresh lemon juice, sprinkle with parsley, and scatter over the capers if using.

Step 6: Optional Pan Sauce

If you’d like extra flavor, remove the fish from the baking dish, then add a splash of dry white wine to the hot pan juices. Simmer for 30–60 seconds, whisk in a small knob of butter, and spoon the sauce over the swordfish before serving.

Serving Suggestions for Baked Swordfish

Baked swordfish is hearty enough to be the star of the plate but mild enough to pair with lots of sides. Here are a few easy ways to round out the meal:

• Fresh and light: Serve alongside an arugula or mixed greens salad dressed with lemon vinaigrette for a crisp contrast.
• Comforting and filling: Pair with roasted potatoes or couscous to soak up the lemon-garlic juices.
• Vegetable-forward: Add grilled or roasted asparagus, zucchini, or Mediterranean vegetables for a colorful side.

A squeeze of extra lemon at the table never hurts, it brightens up every bite.

FAQs About Baked Swordfish

How do I know when swordfish is done baking?
Swordfish is ready when it turns opaque all the way through and flakes easily with a fork. An instant-read thermometer should read 135–145°F in the thickest part.

Can I bake swordfish from frozen?
Yes, but for the best texture, it’s better to thaw it first in the refrigerator overnight. Baking from frozen may take a few extra minutes and can sometimes lead to uneven cooking.

What thickness of swordfish steak works best?
Steaks that are about 1 inch thick bake evenly and stay juicy. Thinner cuts tend to dry out quickly.

Do I need to marinate swordfish before baking?
Not necessarily. Swordfish has a naturally rich, meaty texture. A simple brush of olive oil, garlic, herbs, and lemon is usually enough. If you want to marinate, keep it short—no more than 15–30 minutes if using citrus or vinegar.

Can I reheat baked swordfish?
Yes, but reheat gently. Place leftovers in a 300°F oven for 8–10 minutes or until warmed through. High heat can dry it out.
