How To Cook Swordfish On The Grill

ByLily

Grilled swordfish steaks develop a smoky char that complements their naturally mild flavor and firm texture. If you want to know how to cook swordfish on the grill, the process is simpler than you might think. You only need a hot fire, a few basic seasonings, and about ten minutes of cooking time.

Swordfish is a meaty fish that holds up well on the grate. It does not flake apart like cod or tilapia. That makes it a great choice for beginners who are still learning their way around a grill.

What You Need Before You Start

Good grilling starts with good prep. Gather your tools and ingredients first so you are not running back inside while the fish burns.

  • Two swordfish steaks, about 1 inch thick and 6 to 8 ounces each
  • Olive oil
  • Kosher salt and black pepper
  • Lemon juice or fresh lemon wedges
  • Garlic powder or fresh minced garlic
  • Chopped herbs like parsley, dill, or thyme
  • Metal tongs and a spatula
  • A clean, oiled grill grate

Fresh steaks are best, but frozen ones work fine too. Just thaw them in the fridge overnight. Pat them completely dry with paper towels before cooking. Wet fish will steam instead of sear.

How To Cook Swordfish On The Grill

Follow these steps in order. The whole cook takes less than fifteen minutes from start to finish.

Step 1: Prep And Season The Steaks

Place the dry steaks on a plate. Brush both sides with a thin layer of olive oil. This keeps them from sticking and helps the seasonings cling.

Season generously with salt and pepper on both sides. Add garlic powder and any herbs you like. Let the steaks sit at room temperature for about 15 minutes while you heat the grill.

Step 2: Heat The Grill Properly

Set your grill to medium-high heat. You want a temperature around 400 to 450 degrees Fahrenheit. If you use a charcoal grill, wait until the coals are covered in gray ash.

Clean the grates with a wire brush while they are hot. Then oil them carefully using tongs and a folded paper towel dipped in oil. This step is the number one way to prevent sticking.

Step 3: Grill The First Side

Lay the steaks on the hot grate at a slight angle. Close the lid and cook for 4 to 5 minutes. Do not move them during this time. The fish will release from the grate on its own once it is ready to flip.

Step 4: Flip And Finish Cooking

Slide a spatula under each steak and turn it gently. Cook the second side for another 3 to 4 minutes with the lid closed.

Your swordfish is done when the internal temperature hits 145 degrees Fahrenheit. The flesh should be opaque all the way through but still moist. If you do not have a thermometer, poke the fish with a fork. It should flake easily but not fall apart.

Step 5: Rest And Serve

Move the steaks to a clean plate. Squeeze fresh lemon juice over the top. Let them rest for 2 to 3 minutes so the juices settle.

Serve with grilled vegetables, rice, or a simple green salad. Leftovers keep in the fridge for up to two days.

Tips For Better Grilled Swordfish

Small details make a big difference with this fish. Keep these points in mind.

  • Buy steaks of even thickness so they cook at the same rate
  • Do not over cook. Dry swordfish tastes tough and chalky
  • Use a fish basket if your steaks are thin or fragile
  • Marinate for 30 minutes max. Acid in marinade can break down the flesh
  • Let the grill get hot before the fish goes on. Patience here pays off

Best Marinades And Seasonings

Swordfish pairs well with bright, bold flavors. Try a mix of olive oil, lemon zest, garlic, and oregano. A soy and ginger marinade also works great. For something simple, just use salt, pepper, and a squeeze of lime after cooking.

Avoid heavy cream sauces. They tend to cover up the natural taste of the fish.

Common Mistakes To Avoid

The biggest mistake is flipping too soon. If the fish sticks, give it another minute. It will loosen up when the crust forms.

Another common error is cooking on high heat the whole time. This burns the outside before the inside is done. Medium-high is the sweet spot.

Finally, do not skip the oil on the grates. It takes ten seconds and saves you a mess.

Serving Ideas That Work Well

Grilled swordfish fits many types of meals. Here are a few easy options.

  • Sliced over a bed of arugula with lemon vinaigrette
  • Flaked into tacos with cabbage slaw
  • Served next to roasted potatoes and asparagus
  • Chilled and added to a summer salad the next day

No matter how you serve it, this fish brings a hearty texture that satisfies like steak but cooks in a fraction of the time.

Final Thoughts

Learning how to cook swordfish on the grill opens up a fast, healthy dinner option for any night of the week. Keep your heat at medium-high, oil the grates, and watch your timing. With a little practice, you will get a perfect char every single time.

Grab a couple of steaks this weekend and give it a try. Your grill is ready when you are.
