Ingredients
4 center-cut swordfish steaks, about 6 ounces each, one-inch thick
Salt and freshly ground pepper to taste
3 tablespoons olive oil
2 teaspoons soy sauce
1 tablespoon red-wine vinegar
4 sprigs rosemary or 1 teaspoon dried
1 tablespoon finely chopped garlic
2 teaspoons ground coriander
1 teaspoon ground cumin
2 teaspoons grated lemon rind
¼ teaspoon red pepper flakes
Preparation
- Step 1
Preheat a charcoal grill or broiler, or heat a grill pan.
- Step 2
Sprinkle fish with salt and pepper on both sides. Place oil in a flat dish, and add soy sauce, vinegar, rosemary, garlic, coriander, cumin, lemon rind and pepper flakes. Blend well. Place fish steaks in marinade, coat well on both sides, cover with plastic wrap and let stand for 10 to 15 minutes.
- Step 3
If the swordfish is to be cooked on a grill (or grill pan), place fish on grill and cook for 3 to 4 minutes. Turn and cook for 3 minutes more. Cook longer if desired. If it is to be cooked under a broiler, place fish on a rack and cook for 3 to 4 minutes on each side. Serve with a string bean salad.

Swordfish has a more muscular texture than ahi tuna so cooking it in the same manner will not yield the same silky texture that makes seared ahi so appealing. Swordfish is at its best if cooked briefly in oil + butter over MED heat which will yield a soft succulent texture in the M/MR spectrum.
I sear 3/4 thick steaks of ahi for 1 minute per side on high heat for rare. I sauté 3/4 inch thick swordfish for 2 minutes per side on medium heat for MR. Add aromatics, herbs, etc. for a pan sauce.
Swordfish can be very chewy when not cooked through. We recommend a temperature closer to well done.
I used two large (6 inch each) rosemary sprigs and broke them in half. I used them as a bed for the fish on a gas grill. The fish tasted of smoked rosemary. Absolutely wonderful.
As with any other fish recipe, it's about the freshness. Fresh swordfish doesn't need marinade. To grill a 1-inch thick steak perfectly I brush each side with a thin coat of EVO, salt & pepper, and a sprinkling of paprika. Preheat the grill to 375° and lay the steak diagonally on the grate. After 2-minutes run a spatula under the steak and shift to the opposite angle for about 1-minute to get the cross-hatching. Flip and repeat. The paprika adds a nice rusty gloss to contrast the green beans.
Loved this marinade. Beautiful and easy.
This was delicious! Per comments, I cooked at a medium temperature on grill and reduced coriander and cumin by half. My steaks were a little thicker, so I cooked for 4 minutes per side. Served with lightly steamed asparagus, saffron rice and a 2019 Chablis.
