A practical guide to cooking wild Pacific halibut fillets, portions and cheeks, how to tell it's done, and how to avoid the most common mistake, overcooking it.

Halibut has a reputation for being tricky to cook. It isn't, really, it's just unforgiving of one specific mistake: leaving it on the heat too long past the point it's done. Get the timing right and it's one of the easiest, most reliable fish to cook well. Get it wrong and it turns dry and chalky fast, which is where the reputation comes from.
Here's what actually matters.
Know what you're working with
Wild Pacific halibut is a lean, firm, white fish with very little natural fat. That's exactly why it's easy to overcook, there's no fat to buffer it the way there is with something like salmon or black cod. What you're buying determines the best method:
- Fillets, skin-off: the most versatile cut. Good for pan-searing, baking, or grilling in foil.
- Portions: pre-cut, even in thickness, which makes timing more predictable. A good choice if you're newer to cooking fish.
- Cheeks: a different texture entirely, small, almost scallop-like medallions. Best quickly pan-seared, not baked.
The one rule that matters more than any recipe
Health Canada's official minimum safe internal temperature for fish is 70°C (158°F), checked at the thickest part with an instant-read thermometer. Cook halibut to at least that temperature, then let it rest for a minute or two off the heat. An inexpensive instant-read thermometer is the easiest way to get this right every time, it's one of the best upgrades for cooking any fish, not just halibut.
If you don't have a thermometer, the visual cue is: the flesh turns fully opaque all the way through and flakes easily when you press it with a fork.
Three ways to cook it
Pan-seared (best for fillets and portions). Pat the fish completely dry. Season simply, salt, pepper, that's genuinely enough. Get a stainless or cast iron pan hot with a neutral oil, sear about 4 to 6 minutes per side depending on thickness, don't move it while it's searing. Check with a thermometer and confirm it's reached 70°C (158°F) before removing from the heat. Finish with a squeeze of lemon and a pat of butter off the heat.
Baked in foil (easiest, most forgiving). Wrap the fillet or portion in foil with a splash of white wine or stock, a few slices of lemon, and herbs. Bake at 400°F for about 12 to 15 minutes depending on thickness, then check the internal temperature has reached 70°C (158°F). This method is close to impossible to mess up, which makes it a good starting point if pan-searing feels intimidating.
Cheeks, quick-seared. Halibut cheeks cook fast, often in under 5 minutes total given their small size. Hot pan, butter or oil, sear until opaque through and a thermometer confirms 70°C (158°F). Treat them more like scallops than like a fillet.
How to tell it's fresh quality once thawed
Wild-caught frozen halibut, handled and frozen properly, is genuinely close to fresh in quality, the flash-freezing process locks it in near its catch-day state. What you're looking for once thawed: firm flesh that springs back when pressed, a clean ocean smell (not a strong "fishy" smell), and no discoloration or excess liquid pooling in the packaging.
Where this comes from
The halibut in Ocean2Table's catalog is wild-caught, long-line caught off BC and Alaska, and Ocean Wise Recommended.
