How do I know when the haddock is done?

When preparing fish, there is always the risk of overcooking it and ending up with a dry, flavorless meal. Haddock is no exception.

This delicate white fish is best cooked until it is opaque all the way through. The best way to test for doneness is to insert a sharp knife into the thickest part of the fillet

If the knife meets no resistance and the flesh flakes easily, the haddock is done.

Another sign that the fish is cooked through is that it will begin to turn opaque around the edges. If you see any pink or red remaining in the center of the fillet, then it needs to be cooked for a few minutes longer. 

Once you’ve mastered the art of cooking haddock to perfection, you’ll be able to enjoy this delicious fish any time you like.

With meat thermometer:

You can also check the internal temperature of the fish with a meat thermometer. Haddock is considered safe to eat when it reaches an internal temperature of 145 degrees.

Should I cover the haddock with foil?

There is no need to cover the haddock with foil while it bakes.

Covering the fish will trap it in moisture and may cause it to become overcooked. The best way to ensure perfectly cooked, flaky haddock is to bake it uncovered on a baking sheet lined with parchment paper or foil.
