Ingredients You’ll Need for Perfectly Grilled Swordfish Steaks
Making grilled swordfish steaks is easier than you think. All you need are a few pantry staples and fresh ingredients:
- 4 (6 oz) swordfish steaks – Choose center-cut pieces about 1-inch thick for even cooking.
- 3 tbsp olive oil
- Zest of 1 lemon
- Juice of 1/2 lemon
- 2 cloves garlic, minced
- 1 tsp smoked paprika
- 1/2 tsp sea salt
- 1/4 tsp black pepper
- 1 tbsp fresh dill or parsley, chopped (optional)
Substitutions & Variations: For a spicy kick, add 1/4 tsp cayenne pepper or a dash of hot sauce. Vegan? Swap fish with king oyster mushrooms or portobello caps.
Kitchen Tools You’ll Need
- Grill (gas or charcoal) or grill pan
- Tongs
- Mixing bowl
- Paper towels (for patting dry)
- Instant-read thermometer (optional but helpful)
Step-by-Step Instructions for Grilling Swordfish Steaks Like a Pro
- Prepare the Fish: Pat the swordfish steaks dry with paper towels. This helps achieve a better sear. Place them on a plate and lightly score the skin side if desired (not necessary, but adds texture).
- Make the Marinade: In a small bowl, whisk together olive oil, lemon zest, lemon juice, garlic, smoked paprika, salt, and pepper. Reserve a tablespoon for basting later.
- Marinate (Optional): While not required, letting the fish sit with half the marinade for 15–20 minutes at room temperature enhances flavor. Don’t marinate longer than 30 minutes—swordfish can become mushy.
- Preheat Grill: Heat your grill to medium-high (about 400°F). Oil the grates lightly to prevent sticking.
- Grill the Swordfish: Place the steaks skin-side down (if applicable) on the grill. Cook for 4–5 minutes without moving. Then flip and cook another 3–4 minutes until internal temperature reaches 145°F or flesh flakes easily with a fork.
- Baste & Finish: During the last minute of cooking, brush remaining marinade over the top for extra shine and flavor.
- Rest & Serve: Let rest for 2–3 minutes before serving. Garnish with fresh herbs and a lemon wedge.
Pro Tips for Perfect Grilled Swordfish Every Time
- Don’t Overcook: Swordfish cooks fast. Remove from heat just shy of doneness—it will continue cooking off the heat.
- Use a Thermometer: The most reliable way to check doneness is by internal temp (145°F).
- Flavor Boost Hack: Add capers, olives, or sun-dried tomatoes to the marinade for an Italian-inspired twist.
- Crispy Skin Trick: If your swordfish has skin, cook it first—skin acts as a natural barrier, keeping the flesh moist.

What to Serve With Your Grilled Swordfish Steaks
Grilled swordfish shines when paired with light, vibrant sides that complement its robust flavor:
- Creamy Polenta or Wild Rice Pilaf – Soaks up any juices beautifully.

Storage and Reheating Tips
- Refrigerate: Store leftover grilled swordfish in an airtight container for up to 3 days.

- Reheat Gently: Best reheated in a skillet with a splash of water or broth over low heat to retain moisture. Avoid microwaving—it causes rubberiness.
Frequently Asked Questions About Grilled Swordfish Steaks
Can I grill swordfish without marinating?
Absolutely! Swordfish has a naturally rich flavor that stands up well to direct grilling. Just season generously with salt, pepper, and a touch of olive oil before cooking.
How do I know when grilled swordfish is done?
The safest method is using an instant-read thermometer. Insert it into the thickest part—it should read 145°F. Alternatively, flake with a fork; opaque, white flesh that separates easily means it’s ready.
Is swordfish safe to eat regularly?
Yes, when sourced sustainably. Swordfish is higher in mercury than smaller fish like salmon or tilapia, so enjoy it 2–3 times per month as part of a balanced diet. Look for labels like “MSC Certified” or “Wild Caught Alaskan.”
Can I use a stovetop grill pan instead of an outdoor grill?
Definitely! A well-seasoned cast-iron or nonstick grill pan works great. Preheat on medium-high heat and follow the same timing guidelines.
Why does my grilled swordfish turn out dry?
Overcooking is the main culprit. Also, avoid marinating too long—more than 30 minutes can break down the proteins and lead to a mushy texture.
