This British fish pie recipe is easy to make and can be economical to cook. It calls for pieces of a variety of fish; use fresh, seasonal fish whenever possible, but 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.) Ask your fishmonger for a selection of fish scraps; usually, they will charge you less than the market price. If they aren't willing, then change your fishmonger.

Combining 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.


  • 1 cup fish stock
  • 1 cup milk
  • 12 ounces assorted fish pieces
  • 1 bay leaf
  • 2 ounces (4 tablespoons) unsalted butter
  • 1 medium leek (white part only, washed thoroughly and finely sliced)
  • 2 ounces (a little less than 1/2 cup) all-purpose flour
  • 1 tablespoon finely chopped fresh parsley
  • Salt to taste
  • Freshly ground black pepper to taste
  • 5 1/2 cups mashed potatoes (warm and creamy)
  • Optional: a handful of grated cheddar cheese

  9. Spoon the fish mixture into an ovenproof dish. Cover with a thick layer of mashed potatoes and fluff them up with a fork. For a more professional look, you can pipe the mashed potatoes using a piping bag with a large nozzle.

  • Either buy one type of fish (skin 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.
