Fresh vs Frozen Fish: Choose for the Dish
Fresh fish is not automatically better than frozen fish. Choose by package condition, cold handling, the cut your dish needs and when you can cook it.
Most people who say they can't cook fish have really just never been told the two or three things that matter: how thick the fillet is, how hot the heat is, and how to recognize done before it becomes overdone. This collection covers those fundamentals — choosing fresh fish at the counter, matching cooking method to cut, and hitting 145°F (63°C) without sailing past it. Every guide here is written for a regular home kitchen: a sheet pan, a skillet, an instant-read thermometer. We give times as honest ranges tied to thickness rather than false precision, we explain the visual cues that back up the thermometer, and we tell you exactly what went wrong when a fillet turns out dry — so it doesn't happen twice.

Fresh fish is not automatically better than frozen fish. Choose by package condition, cold handling, the cut your dish needs and when you can cook it.

Bake salmon at 400°F (205°C) on a lined sheet pan, skin side down, until the thickest part reaches an internal temperature of 145°F (63°C) and the flesh…

To pan-sear fish, pat the fillet completely dry, season it, and heat a heavy skillet over medium-high until a high-smoke-point oil shimmers.

Fish is done when it reaches an internal temperature of 145°F (63°C) at its thickest point — the FDA's recommended safe temperature for fin fish.

To poach fish gently, arrange evenly sized portions in one layer and cook them in seasoned liquid held at a bare simmer, not a rolling boil.

Lay the cold fillet skin-side down on a clean board and sweep your fingertips across its thick centre section to find the pin-bone tips.

Place fish in a single layer above—not in—gently boiling water, cover the pan, and cook with circulating steam.

Take fresh fish home in a cold bag or cooler, then refrigerate it at 40°F (4°C) or below and cook it within two days of purchase.

Thaw frozen fish in the refrigerator overnight whenever possible.
