Fish Au Gratin

    Cod Au Gratin

    A lovely dish, full of comfort and warmth.   My father used to say that fish was ‘brain food’.  This is ‘brain food’ that the stomach will also love.

    Great when it’s hot out of the oven, and this recipe can also be fully cooked, then frozen.   Thaw on countertop and then reheat to warm through.  This dish is always enjoyable.
