With frozen fish amounting to approximately half the fish sales in the US, this article will explore the best ways to marinate frozen fish and answer the most frequently asked questions on the subject.
Let’s dive in.
Does marinating frozen fish impart flavor?
Unless you are a fish purest and love the flavor of fish from the ocean, many people opt for marinating fish to add flavors they love. Traditionally, tomatoes with dill and chives with melted butter would be the base for a classic combination based on French cuisine.
But you can be more adventurous and add some zing to your fish with the string spices of the Caribbean with allspice, garlic, and chili.
The flavor boost can be a sensational change to the fish, turning it from something enjoyable but slightly bland to a crescendo of flavors wrapped around delicate fish flakes.
But all of that is fine with fresh fish. How about frozen fish stored in solid icy slabs? Will it marinate, penetrate the ice and add flavor to the fish, or is it a fool’s errand with nothing to be achieved?
Adding a marinade to a frozen piece of fish will do nothing. It may impart a slight flavor, but it is nothing worth mentioning. The marinate will not be able to penetrate the ice, so that you will be wasting your time, effort, and marinade ingredients.

When the fish’s juices have leached out of the flesh, you can be left with a firm, salty piece of fish. What didn’t come out during the leaching process was the salt of the ocean.
