Best Practices for Grilling Swordfish

  • Use thicker steaks. Grilling excels at cooking cuts 1-1.5 inches thick. Thinner fillets are likelier to dry out.
  • Pick a hot zone. Sear the fish directly over high heat to caramelize the exterior. Avoid cooler areas.
  • Coat with oil. Lightly brush steaks with oil so they don’t stick. Oil also encourages browning.
  • Go for a two-level fire. Sear first over direct heat, then move to indirect heat on the grill to finish cooking.
  • Flip only once. Resist flipping repeatedly. Let the fish develop a crust before gently flipping.
  • Check for doneness. Grill until swordfish reaches an internal temperature of 145°F.

Grilling Times and Temperatures

Properly grilling swordfish comes down to managing two key factors – temperature and time. Use these guidelines for perfect results:

Grilling Temperatures

  • Use medium-high to high heat, around 400-500°F
  • Allow the grill to preheat fully before adding fish
  • Quickly sear fish over direct heat to caramelize the exterior
  • Move to indirect heat on the grill if needing to finish cooking

Grilling Times- How Long To Grill Swordfish

The table below provides estimated grilling times based on the thickness of swordfish steaks:

ThicknessGrilling Time Per Side
1 inch4 minutes
1.5 inches5-6 minutes
2 inches6-8 minutes
  • These times are for medium doneness. Increase time by 1-2 minutes if desiring well-done.
  • Check internal temperature with a meat thermometer for accuracy.
  • Let swordfish rest for 5 minutes before serving.

Tips for Successfully grilling swordfish

  • Oil the grill grates and fish to prevent sticking
  • Flip the fish gently once with tongs or a spatula
  • Resist the urge to flip multiple times
  • Close the lid between flipping to maintain heat
  • Adjust heat level and times as needed

Monitoring time and temperature closely results in tender, juicy grilled swordfish. Let the fish develop a nice sear before flipping. Use these grilling pointers for the best outcome.

Skewer and Plank Variations

For fun presentation and added flavor, try grilling swordfish on skewers or planks:

  • Skewers – Thread swordfish chunks with veggies like onions, bell peppers, or zucchini. Brush with oil and grill, turning frequently.
  • Planks – Place swordfish steaks on pre-soaked cedar or oak planks. Imparts a subtle woody taste as the fish cooks.

  • What type of grill is best for cooking swordfish?

    A charcoal grill is ideal as it reaches the highest heat for searing. A gas grill also works well. The grates should be thoroughly cleaned and oiled before grilling.

  • How do I prevent swordfish from sticking to the grill?

    Use a non-stick grilling mat, coat the fish with oil, or par-cook it before finishing quickly on the hot grill.

  • Can I grill frozen swordfish?

    It’s best to thaw swordfish first in the fridge overnight. Grilling partially frozen fish leads to uneven cooking.

  • What happens if I overcook swordfish on the grill?

    Overcooking leads to very firm, dry flesh. Check the thickness and use a meat thermometer to prevent overcooking.

  • What are the best seasoning for grilled swordfish?

    Lemon-herb marinades or dry rubs work well. Also consider garlic, paprika, cayenne, chili powder, salt and pepper.
