Fish Pie: Simply Delicious

Fish Pie is a classic dish is a pie that has fish in it. Pretty basic explanation but that really is what it is. Normally made with white fish (cod, haddock, or halibut) in a white sauce. Hard boiled eggs are sometimes added as well. The pie is made in a deep dish.

The fish is not covered by a pie crust, but mashed potatoes are used to over it instead. The pie is sometimes also called the “fisherman’s pie” because it is similar to the Cottage Pie / Shepard’s Pie

Fish Pie is one of those dishes that always brings feelings of comfort and warmth. Nothing quite beats a serving of fish cooked in a creamy sauce, topped with crispy potato served piping hot from the oven. Fish pie is also a great nutritious family meal or winter warmer.

As with most dishes you can mix this dish up depending on what your favourite catch of the day is. May it be salmon, cod, prawns or haddock, mixing your favourite fish with a creamy white sauce recipe and topping it with mashed potato is always a winner.

The pie can be assembled and chilled in the fridge for up to 12 hours before cooking which helps when entertaining too. This is a perfect dish for a family get together, From the youngest children to the eldest adults everyone can have a slice of this pie.

Freezing Fish Pies All The Information

FREEZE : You can freeze the cooked pie for up to 1 month. Reheat in the oven at 200°C/180°C fan/Gas 6 for about 45 minutes. The recipe I have included here doesn’t have the addition of eggs. However if you did choose to add to eggs and you wanted to freeze your pie then don’t include them! Egg turn the dish rubbery as they don’t freeze well.
