To poach fish in milk using an oven, start by preheating your oven to 375 degrees fahrenheit. Place your cod onto a baking sheet with a wire rack, the wire rack helps the air circulate around the fish helping it get nice and crispy. Then rinced it off and placed it on a 2nd clean baking sheet covered with parchment paper.

When it comes to frozen fish, treat it just like fresh (once its thawed)! Season all over with salt and pepper. Bake on top rack for 10 minutes, turn over.

Also, for reference, we had frozen our fish for a couple weeks before using it and it still came out fabulous when we cooked it. Next, pour 2 cups of whole milk and a pinch of salt in a shallow dish and set 2 skinless fillets of fish into the baking dish so the milk comes halfway up the sides of the fish. Preheat the oven to 200°c (180ºc fan) and pat cod fillets with a paper towel until dry.

We like white ceramic for the pictures, but glass is perfectly fine! There was enough marinade left to cover 1 or 2 more pieces of fish. Usually you can only find them frozen.

I followed the ingredients list from here. *keep frozen until ready to cook. Turn product halfway through bake time for best results.

The black cod we used weighed about 19 ounces. Just like our other top brands, there was no unpleasant fishy flavor—just good white fish. I broke it up into 3 different pieces and used a brush to very thoroughly cover all 3 pieces.

Bake for approximately five minutes per ounce of fish. Cover the dish or pan with foil, and place it into the oven. Oven oven prepare from frozen state.
