This is a good way to cook fried fish for many. It can easily be made ahead and kept cool until its time to cook it.
These are the things you need.
Pour the margarine into a bowl large enough for the filet to be fully covered. Mix breadcrumbs with salt and pepper.
Dip the fish into the liquid margarine and let excess run off.
Cover the fish with breadcrumbs.
Place the filets in a bakingtray, there's no need to grease or line with parchment.
Preheat your oven to 250 degrees Celsius. Put a thermometer in the thickest part of one of the filets and bake to 56 degrees Celsius.
Take out the fish and let it cool just a few minutes. Serve with potatoes and fresh dill.
This way of cooking will actually contain less fat than it would cooking it the traditional way. Enjoy
