Grilled swordfish is easy to make and incredibly delicious. It has a mild, yet slightly sweet flavor that pairs well with lots of sides. Since swordfish has a firm, meaty texture, it is great for grilling. And the best part? You don’t have to be a professional chef to make it happen.
Get that grill hot and ready, and prepare yourself for a treat!
Simple Grilled Swordfish
This is an easy recipe that takes just a few minutes to prepare and a few minutes on the grill. Just a basic seasoning lets the flavor of the fish shine. But if you want to make a quick marinade, we have some options in this cooking guide. Just make sure you don’t let it marinate to long or the acids in the marinade will break the meat down and give it a mushy flavor.
Choosing Your Swordfish Steak
When choosing swordfish steak, there are a few things to keep an eye out for. First, the color of the meat should be bright, pinkish-white, and have a fresh, clean smell.
Avoid fish that looks too dry, or has a strong fishy odor. As for the question of fresh versus frozen, both can work quite well. Don’t worry if you can’t find fresh fish. Most of it gets a flash freeze on the fishing boat to stay fresh.
Swordfish is one of the few fish that can be cut into steaks and this is the perfect weather for grilling it in the backyard. This is a nice mild-flavored, firm-fleshed fish with a texture similar to Ahi tuna, or Mahi-Mahi although quite different in taste.
When buying swordfish steaks look for American swordfish and not imported. Our swordfish comes from the waters of the Pacific….specifically from Hawaii.
How to Grill Swordfish Steak
Here is a brief overview to get an idea of what to expect with the recipe for grilled swordfish steak. Scroll down to the printable recipe card for all the details.
Read our options below if you want to make a marinade before grilling the fish.
- Prepare your grill and let it heat up for about 15 minutes until it reaches a temperature of 500°F.
- Brush the swordfish steak on both sides with oil and season generously with salt.
- Grill the swordfish steaks over high heat, as close to the heat as possible.
Optional Marinade for Swordfish
If you want to marinate the fish before grilling, here are a few ideas for marinades. Just make sure you don’t let the swordfish soak in the marinade for more than 10 to 15 minutes (thinner cuts should have less).
Mediterranean Marinade: 3/4 cup olive oil, 1/2 cup red wine vinegar, 2 cloves minced garlic, salt, pepper, 1 to 2 tablespoons of dried herbs (use a combination of basil, oregano, sage, thyme, and rosemary).
Asian-Inspired Marinade: 1/3 cup soy sauce, 1/4 cup rice vinegar, 3 tablespoons sesame oil, 1 tablespoon grated fresh ginger, 2 cloves minced garlic, 1 teaspoon chili flakes (optional)
Garlic Lemon Marinade: Juice and zest of 2 lemons, 3/4 cup of olive oil, 4 minced garlic cloves, fresh chopped dill, salt and pepper.
Tips for a Perfect Swordfish Steak Recipe:
- Since swordfish has such a firm flesh, it doesn’t fall apart when it is flipped over on the grill and it holds up to the heat long enough to get those nice grill marks without over-cooking.
- You can cook this steak on an indoor grill just as successfully as an outdoor grill. This makes a great year-round recipe.
- Brush the grill or outdoor grate with oil before cooking the swordfish. That will prevent the fish from sticking to the grill.
- Don’t overcook the swordfish, or it will become dry. If you’re not certain about how ‘done’ the fish is, then check the internal temperature with an instant-read thermometer. The internal temperature should be 145°F per the USDA. I personally like to cook it to 135°F so it has a tender, buttery texture.
