How To Grill Swordfish Steaks On Gas Grill?
Grilling swordfish steaks on a gas grill means mastering temperature control and timing for a perfectly cooked, flavorful meal.
You will want a consistent medium-high heat and a watchful eye to achieve that ideal sear and tender interior.
Why Swordfish is Great for Grilling
Swordfish is a fantastic choice for the grill because of its firm, meaty texture. It holds together beautifully, unlike many other fish.
This sturdy nature makes it less prone to breaking apart on the grates, giving you more confidence as you cook.
Picking the Best Swordfish Steaks
When you are at the fish counter, look for swordfish steaks that are about 1 to 1.5 inches thick. This thickness is ideal for grilling.
The fish should look moist and have a mild, fresh scent, not overly fishy. Avoid any dry or discolored pieces.
Getting Your Steaks Ready
Proper preparation sets the stage for success. You want your swordfish ready to meet the heat.
Taking a few moments here makes a big difference in the final taste and texture of your meal.
To Rinse or Not to Rinse?
Some people like to rinse fish, but experts often advise against it for safety reasons.
We found that rinsing can spread bacteria around your kitchen (USDA). Just pat it dry instead.
Patting Them Dry
This step is often overlooked but it is absolutely key. Use paper towels to pat your swordfish steaks very dry on all sides.
A dry surface helps you get a beautiful, crispy sear. Wet fish will steam instead of grill.
Setting Up Your Gas Grill
Your grill is your cooking partner. Make sure it is ready to perform its best for your swordfish.
A little prep work here makes the actual grilling smooth and enjoyable.
Grill Cleaning Basics
Before you even think about turning on the gas, make sure your grill grates are clean. Use a good grill brush to remove any leftover bits.
Clean grates stop your fish from sticking, which is a common grilling frustration.
Target Temperature
Preheat your gas grill to a medium-high heat, aiming for 400-450°F (200-230°C). This can take about 10-15 minutes.
We found that this temperature range gives you a nice sear without drying out the inside of the swordfish too quickly.
Flavor Boosts: Seasoning Your Swordfish
Swordfish has a mild, delicious flavor on its own, but seasoning can truly make it sing.
You have many options, from simple to more elaborate, depending on your taste.
Simple Salt and Pepper
Sometimes, less is more. A generous sprinkle of kosher salt and freshly cracked black pepper is often all you need.
This classic pairing allows the natural flavor of the swordfish to shine through beautifully.
Marinade Magic
If you want to add more depth, consider a quick marinade. A mix of olive oil, lemon juice, garlic, and fresh herbs (like dill or parsley) works wonders.
Marinate for just 20-30 minutes; swordfish doesn’t need long, or the acid can start to cook it.
The Grilling Process
Now for the main event! Grilling swordfish is a relatively quick process, so stay focused.
You will be surprised how fast this delicious meal comes together.
Placement and Initial Sear
Lightly oil your hot grill grates using a paper towel dipped in high-heat cooking oil. Place your seasoned swordfish steaks directly on the hottest part of the grill.
Close the lid and let them sear undisturbed for about 4 minutes.
When to Flip Your Fish
After 4 minutes, you should see nice grill marks. Gently flip the steaks using a wide, thin fish spatula.
Close the lid again and grill for another 2-4 minutes, depending on thickness and your desired doneness.
Checking for Doneness
The best way to check for doneness is with an instant-read meat thermometer. Insert it into the thickest part of the steak.
For moist, flaky swordfish, aim for an internal temperature of 130-135°F (54-57°C). Many chefs recommend this for optimal texture.
| Steak Thickness | Approx. Grill Time (Per Side) | Internal Temperature Goal |
|---|---|---|
| 1 inch | 4-6 minutes | 130-135°F (54-57°C) |
| 1.5 inches | 6-8 minutes | 130-135°F (54-57°C) |
Resting is Best
Just like with meat, fish benefits from resting after cooking. This allows the juices to redistribute throughout the steak.
Move your swordfish to a plate, loosely tent it with foil, and let it rest for 5 minutes.
Avoid These Common Grilling Mistakes
Even seasoned grill masters can slip up. Being aware of potential pitfalls helps you achieve perfect results every time.
Keep these tips in mind to make your swordfish grilling a breeze.
- Don’t grill cold fish; let it sit out for 15 minutes.
- Avoid flipping too early; let it sear.
- Don’t overcook; use a thermometer.
- Do not forget to oil your grates.
- Skip thin steaks; they tend to dry out quickly.
Serving Up Your Masterpiece
Once rested, your grilled swordfish is ready to be the star of your meal. A squeeze of fresh lemon juice is almost always a welcome addition.
Serve it with a fresh salad, roasted vegetables, or a light pasta dish for a complete and healthy meal.

Frequently Asked Questions
Is swordfish healthy to eat?
Yes, swordfish is a healthy protein source, packed with lean protein and beneficial omega-3 fatty acids. While it contains mercury, moderation is key; many health organizations suggest limiting consumption, especially for certain groups (FDA).
Can I grill frozen swordfish steaks?
It is best to grill swordfish that has been fully thawed. Grilling from frozen can result in uneven cooking, where the outside burns before the inside cooks through. Thaw your steaks in the refrigerator overnight for best results.
What internal temperature is considered safe for swordfish?
While the USDA recommends cooking fish to 145°F, many chefs aim for 130-135°F for swordfish, allowing for carryover cooking and a moister texture. If food safety is your top concern, cook to 145°F, but know it might be slightly drier.
How do I prevent swordfish from sticking to the grill?
To prevent sticking, ensure your grill grates are spotlessly clean and very hot before you start. Then, lightly oil the hot grates just before placing the fish. Make sure the fish is patted very dry and do not try to flip it too soon.
What sides pair well with grilled swordfish?
Grilled swordfish pairs wonderfully with a variety of light and fresh sides. Think grilled asparagus, a vibrant corn salad, lemon-herb roasted potatoes, or a simple green salad with a vinaigrette dressing. The mild fish allows other flavors to shine.
