No help here, I guess, I like to eat leftover cooked fish cold, as-is, the next day.

I'd make fish taco's. Or smush it with cracker crumbs, green onions, and such for something like lightly fried crab cakes = halibut cakes. Dollop some mayo on top and sprinkle with smoked paprika to serve. BTW you can refreeze halibut after it is cooked, just not refrozen from raw.

I would go with the lemon caper sauce, myself. Yum.

Fish and chips!

It's already cooked......would you bread and re cook it?

Personally, I wouldn’t re cook it. It’s such a delicate fish, I think it would ruin the texture, and the flavour. That said, I would gently reheat it for the sauce you suggested or the tacos suggested.

I vote for fish tacos, too. One of my favorite ways to eat leftover halibut. I heat cooked fish in the microwave on about 20% power just until it's hot enough. It doesn't cook it further - some things take only 30-60 seconds.

I am about 45 min away, I'll come over .... just for the .... halibut

bwah ha ha .... never get tired of that one ...

Bragu I knew there had to be a pun in there but I couldn’t put my finger on it. I did figure it out before reaching this page which I found funny:

I love fish tacos so that is how I would use it.

I didn't realise it was all cooked.

I flounder over a reason not to use halibut ... It'd likely not make a whale of a difference...

Well maybe it was just a fluke, but I did flounder over what to do with it, had quite a group (er) giving me ideas of what I cod do with it. Froze most of it....fish tacos sounds like a good idea.
