Forget everything your paranoid aunt told you about chicken. Haddock is a delicate, flaky fish, not a brick of potential salmonella. The golden number for perfectly cooked haddock is 145°F (63°C) at its thickest part, according to the FDA. But here’s the kicker: you don’t need to be a human lab coat to nail it.
Why 145? Because at that temperature, the proteins relax, the flesh turns opaque, and the fish basically surrenders with a sigh. Cook it beyond, and you’ve created a dry, sad, fishy hockey puck. And nobody wants to chew a hockey puck that smells like the pier.
The Fork Trick: Your New Best Friend
If you don’t own a thermometer—or you lost it in the same black hole that ate your left sock—use the fork test. Take a fork, gently poke the thickest part of the fillet, and give it a little twist. If you can see the flesh separate into big, beautiful, translucent flakes, you are golden.
The fish should flake like a bad romance—easily, with zero drama. If it resists, it’s raw. If it crumbles into dust, you’ve committed seafood murder. Aim for that sweet spot where it’s just firm enough to hold a shape but soft enough to be a polite dinner guest.
