How To Cook Fish When Still Frozen

A recent trip to a local health food market found me with a package of frozen Alaskan cod and a new idea: cooking the fish while it’s still frozen.

My whole life I was told to either put the fish in the fridge overnight to thaw (recommended), or you could get away with a quick thaw in the sink under some water (not officially recommended but guilty as charged). I don’t remember anyone I know cooking fish straight out of the freezer. Well, apparently you can, according to Alaska Seafood, and so I decided to give it a try.

I’ve only done this once before, with those delicious frozen dinners by Love The Wild. At the time I didn’t give it much thought, but why not? Why can’t you cook fish right out of the freezer.

I also get to try a sort-of new fish. I’ve never cooked Alaskan (Pacific) cod, because why would I? My hometown is synonymous with codfish, although I prefer haddock, and despite what the press often states, there is always local cod in our local markets.

One of the best parts of having this blog is that I have an excuse to get out of my seafood comfort zone and try new fish and new methods for the sake of you all: the readers. Where I’m from we are spoiled with great seafood all year long, so that many of my friends and family are not adventurous when it comes to trying unfamiliar species. Can’t really blame them, but I like to try new things and gives me the opportunity.

So now I have the chance to sample some frozen Alaskan cod from Orca Bay Seafoods (now known as Orca Bay Foods). Although this is not necessarily a review of their product, Orca Bay impressed me with their wild, and domestically processed (product of USA) cod.

Out of the bag these fillets were rock solid and nearly pure white, I’m not used to seeing uncooked codfish as white as halibut. At $10 for 2 5oz portions it seems not too expensive as the main part of a dinner for two.

  • Alaska Seafood suggests thicker pieces cook longer.

As it cooked I could hear all the water sizzling away and I have to admit, I was in doubt about the cooking time of about 15 minutes. Also, I’m not sure what constitutes a thick piece, but Alaska Seafood suggests thicker pieces cook longer. At a total of 10 ounces I’m betting these Alaskan cod fillets are not considered big pieces.

At 4 minutes I basted the fish in lemon juice, extra virgin olive oil and fresh dill (grown in my mini-aquaponics setup) that I whisked up. I then proceeded to cook the fish for another 11 minutes. With 4 minutes left I basted again because nothing bad ever happens from over basting. I did notice that my glasses were covered in grease as if I were sauteing, so still plenty of water to evaporate I assumed. At the 15 minute mark they were not done and so I let them go another five.

The Verdict on Cooking Fish That is Still Frozen

I would normally cook this a little longer, maybe 25 minutes total, but it’s been a while since I cooked codfish and I was starving. It was much better than I expected and I have a feeling that cooking with all that water helped keep it moist, almost poached and I got a lot of good, clean, cod flavor.

Without the breadcrumbs, garlic, onions and the like, it was a low-FODMAP seafood dinner that took minimal effort. It’s safe to say that the next time I buy cod it will be local, but if you don’t have a local source, Orca Bay Alaskan Cod is a quality, domestic, product.

As far as cooking fish from frozen, I think I will still be thawing mine out, but I’m sure glad to know there is a pretty good method of cooking fish straight from the freezer. No longer fret it you didn’t take the fish out in time, just follow the instructions over at Alaska Seafood to learn how to use your favorite cooking techniques with still-frozen fish!
