Halibut & Cucumber Sauce

Grilled halibut with a cold cucumber sauce is one of those pairings that just works. The hot, butter-basted fish hits the plate alongside a cool, tangy sauce made from shredded cucumber, sour cream, chives, and lemon juice. That temperature contrast alone makes every bite interesting.

The cucumber sauce comes together in minutes and benefits from chilling while you grill. Shredding the cucumber rather than dicing it matters here because shredded cucumber releases its juice into the sour cream base, creating a thinner, more sauce-like consistency. Diced cucumber would sit on top instead of blending in.

Halibut is lean and dries out fast on the grill, so the butter basting isn’t optional. Brush it on both sides, multiple times during cooking. A wire grill basket keeps the steaks from sticking and falling apart when you flip, which halibut is notorious for.

Pro Tips

• Grill over medium-hot coals, not screaming hot. Halibut cooks quickly and needs gentler heat to stay moist.
• The fish is done when it flakes easily with a fork but still looks slightly translucent at the very center. Carryover heat finishes the job.
• Make the cucumber sauce ahead and let it chill for at least 30 minutes. The flavors need time to meld.
• Pat the halibut dry before grilling to prevent steaming. You want char marks, not a poached surface.

Variations

• Add fresh dill to the cucumber sauce for a Scandinavian twist.
• Use Greek yogurt instead of sour cream for a lighter, tangier sauce.
• Swap halibut for swordfish or mahi-mahi if halibut isn’t available. Both hold up well on the grill.
