This easy Fish Pie Recipe is perfect for you if you love fish and you are a big fan of a Traditional Cottage Pie or any other pot pie. It is the ultimate British comfort food made with chunky pieces of fish, leeks, peas, and aromatic fresh herbs in a creamy white sauce, topped with fluffy and cheesy mashed potatoes.

My creamy Fish Pie Recipe is very easy to make and is an absolute crowd-pleaser. The white sauce has leeks and tarragon that pairs perfectly with the fish. And the best part is that you don’t need to pre-cook the fish if you use fresh, good-quality ones!
What Fish to Use ?
Although there is no set rule about what type of fish to use, I suggest using an equal amount of 3 different types of fish (usually 1 part of salmon, 1 part of white fish, and 1 part of smoked fish). Add some prawns for a different texture and luxury feel to the dish if you like. For this recipe, I used 200 grams of salmon, 200 grams of cod, 200 grams of smoked haddock, and 150 grams of tuna (to add a bit of extra color but you can omit tuna with extra salmon or cod). If you don’t want to prepare your own fish mixture, you can buy them from your fishmonger or supermarkets.
How to Make Fish Pie?
This hearty fish pie recipe is very easy to make with a little preparation. To achieve the best results, you need to follow few tips and simple steps:
- Cook the potatoes – Peel the potatoes and cut them into chunks. The best choice of potatoes is floury potatoes such as Maris Piper, red russets, desire or King Edward. Place the potatoes in a large pan and fill tehm with enough cold water to cover them. Bring the potatoes to a boil on high heat then lower the heat. Gently simmer for 20-25 minutes or until soft in the middle. Always start cooking the potatoes from cold water. Otherwise the outside will be mashy and start to flake while the core is still uncooked. Start preparing the fish pie sauce while the potatoes are cooking.
- Prepare the fish pie sauce – Place a pan on medium heat and melt the butter. Add the leeks and sauté until soft.
Sprinkle on the flour and stir to combine.
Cook for a minute and whisk in a little of the warm milk at a time. Stir continuously until you have a smooth and velvety mixture and cook for few minutes to thicken it. Add the fish mixture, dill, tarragon, peas, freshly ground black pepper, and salt.
Give the mixture a good stir and remove from the heat. Spoon the mixture into a pie dish size of 25 cm diameter (or similar size of rectangular or oval oven dish) making sure there is some space left for the mashed potatoes.
- Prepare the cheesy mashed potatoes – Preheat the fan oven to 180 °C and start preparing the mashed potatoes. When potatoes are soft in the middle, drain well and return them back to the pan. Put the pan back on low heat and then let all the water evaporate for 30 seconds. Remove from the heat then add the double cream, butter and salt. Mash with using a masher or a ricer until smooth and stir in the grated cheddar cheese.
- Assemble the Fish Pie – Spoon the mashed potato on top of the fish mixture and spread it out evenly using a fork or pallet knife. Give it a lined pattern to help the mash crisping up.
Place the dish in the oven and cook for 30-35 minutes until the top is golden and the filling is bubbling.
The main reason to have a watery fish pie is the use of frozen fish. Use good quality fresh fish if possible. If you want to use frozen fish, make sure you thaw them in the fridge overnight and poach them for 5 to 6 minutes before adding them to the fish pie sauce.
I suggest you serve this hearty dish with some steamed vegetables of your choice or a healthy bowl of salad such as Rocket and Parmesan Salad or Greek Salad.
Yes, you can reheat the fish pie in the microwave for a couple of minutes or in the preheated oven (180 °C fan oven) for 15 to 20 minutes. Cover the fish pie with tin foil before putting it in the oven.
You can freeze the fish pie only if you made it with fresh fish. Let the leftover fish pie cool down for few hours and put it in an airtight container before freezing. You can keep it in the freezer for up to 3 months. Thaw it in the fridge overnight before reheating and make sure it is piping hot before eating!
I hope you enjoy the process of making this delicious Fish Pie as much as you enjoy eating it! 🙂
Bon appétit! / Afiyet Olsun!
