This British fish pie recipe is nutritious, easy, and can be economical to cook. Ask your fishmonger for a selection of fish scraps and, usually, they will charge you less than the market price. If they aren't willing, then change your fishmonger.

Buy chunks of fresh, seasonal fish whenever possible, frozen is fine as long as you defrost it first. If you don't, you will end up with a lot of water in the bottom of your dish.
As you can see in this recipe which contains fish, leeks, milk, butter, and potatoes, a fish pie is a one-pot supper dish. Some like to sprinkle a fish pie with grated cheese but this is optional, as is the addition of hard-cooked eggs seen in some recipes. Serve the pie with peas or other fresh greens.

Oh, and by the way, with all that lovely fish and vegetables, this dish is good for you, too.

Tips

  • Either buy one type of fish (skinless and bones removed) cut into bite-sized chunks, or mix different fish and/or prawns together. 
  • Choose non-oily, fleshy fish such as salmon, cod, smoked haddock, and coley, which is similar to cod.
