Polynesian Sea Steaks

Polynesian cooking leans on bold marinades to do the flavor work, and this one delivers. Teriyaki sauce, fresh ginger, scallions, and grated orange zest combine into a salty-sweet-citrus bath that transforms plain fish steaks in under an hour.

The 45-minute marinate is doing real work here. The teriyaki carries soy depth and sweetness into the flesh while the fresh ginger adds that sharp, peppery warmth that dried ginger just can’t replicate. Orange zest is the quiet surprise. It brightens everything and keeps the flavors from going one-note salty.

Broiling with reserved marinade brushed on during cooking builds a sticky, caramelized glaze on the surface. You want to see those edges darken and lacquer up. That’s where the flavor concentrates.

Chef Tips

• Use firm fish steaks that hold up to broiling: swordfish, mahi-mahi, tuna, or halibut work best. Flaky fish like cod will fall apart.
• Flip the steaks in the marinade a few times during those 45 minutes so both sides absorb evenly.
• Brush the reserved marinade on generously while broiling. Each coat adds another layer of glaze.
• Test for doneness with a fork. When the fish flakes easily and looks opaque through the center, it’s ready. Don’t wait for it to look dry.

Variations

• Pineapple glaze: Add crushed pineapple juice to the marinade for an even more tropical, sweet-tart profile.
• Grilled version: These steaks take beautifully to an outdoor grill. Use a well-oiled grate and the same brushing technique.
• Spicy Polynesian: Stir in sambal oelek or sriracha to the marinade for a chili heat layer underneath the sweetness.
