How to Make Fish Pie with Potato Topping
- For the Fish Filling: Let’s build the rich, silky heart of this pie by poaching flaky fish in milk, then melding it with a buttery sauce that locks in moisture and flavor throughout.
- Poach fish: bring milk and butter to a gentle simmer in a pan, submerge white and smoked fish fillets, cook gently for 5–6 minutes until just opaque, then drain.
- Sauté vegetables: melt butter in the same pan over medium heat, add sliced leeks or onions, cook until soft, translucent, and fragrant, about 3–4 minutes.
- Make sauce: sprinkle flour over veggies, stir constantly for 1 minute, whisk in reserved milk gradually until smooth and bubbling, simmer 2–3 minutes until sauce coats the back of a spoon.
- Combine filling: flake poached fish into sauce, stir in frozen peas and chopped parsley, season with salt, pepper, and a pinch of nutmeg for warmth.
- For the Potato Topping: Next, we’ll whip fluffy mashed potatoes with butter and warm milk, creating the golden, creamy blanket that crowns our comforting fish pie.
- Boil potatoes: add peeled, chopped potatoes to boiling salted water, cook 15–20 minutes until tender when pierced with a fork, then drain thoroughly.
- Mash potatoes: return hot potatoes to pan, mash with butter and warmed milk or cream, beating until smooth, soft peaks form for that perfect crust.
- Assemble pie: spread fish filling evenly in a baking dish, spoon potato mash on top, smooth edges, then use a fork to create decorative peaks for browning.
- Bake until golden: place pie in preheated oven at 375°F (190°C), bake 20–25 minutes until the topping is lightly golden and sauce bubbles at the edges.
Optional: Sprinkle grated cheddar or fresh parsley before serving.

How to Store and Freeze Fish Pie with Potato Topping
Fridge: Store leftover fish pie in an airtight container for up to 3 days. Reheat in the oven for best results, ensuring it reaches a temperature of 165°F (75°C).
Freezer: For longer storage, freeze the unbaked fish pie tightly wrapped in plastic wrap and aluminum foil for up to 2 months. Thaw overnight in the fridge before baking.
Reheating: If reheating a baked pie, place it in a 350°F (175°C) oven, covered with foil, for about 20–30 minutes until heated through.
Serving fresh: For the best texture, enjoy your fish pie fresh. However, it holds its rich flavors well even after storing!
Expert Tips for Fish Pie with Potato Topping
- Choose fresh fish: Use the freshest white and smoked fish you can find to ensure the filling is tender and flavorful, avoiding any fishy aftertaste.
- Don’t overcook fish: Poach the fish gently just until opaque to keep it flaky and moist, preventing a tough or dry filling.
- Warm liquids for mash: Always heat milk or cream before adding to your potatoes—cold liquids can make the mash gluey instead of silky smooth.
- Perfect potato texture: Use floury potatoes like Maris Piper for fluffy mash; waxy potatoes will result in a denser, heavier topping.
- Season in layers: Season your fish sauce and potato mash separately to build deep, balanced flavors throughout the pie.
- Golden topping tips: Use a fork to create peaks in the potato topping; these catch the oven’s heat better, giving you that irresistible golden crust.
Make Ahead Options
These Fish Pie with Potato Topping are perfect for busy weeknights or meal prep enthusiasts! You can prepare the fish filling up to 24 hours in advance by poaching the fish and making the sauce, then cool it completely before refrigerating in an airtight container. The creamy potato topping can also be made ahead; just mash the potatoes and store them separately, making sure to tightly cover them to prevent browning. When you’re ready to eat, simply reheat the fish filling in a saucepan while the potatoes warm up in the microwave. Assemble and bake as per the recipe, and you’ll enjoy a comforting meal that tastes just as delicious as if it were made fresh!
Fish Pie with Potato Topping Recipe FAQs
How do I know if my fish is fresh enough for the pie?
Look for fish with firm, translucent flesh that springs back when pressed. Avoid any with a strong, fishy odor or dark spots all over. Fresh fish is key to a light, flaky filling that really shines in this pie!
Can I store leftover Fish Pie with Potato Topping in the fridge?
Absolutely! Store leftovers in an airtight container and keep it refrigerated for up to 3 to 4 days. When reheating, cover the pie with foil and warm it in the oven at 350°F (175°C) until heated through to preserve its creamy texture.
Is it okay to freeze Fish Pie with Potato Topping?
Yes, definitely! For freezing, assemble the pie but don’t bake it yet. Wrap the dish tightly in plastic wrap and then foil to prevent freezer burn. It will keep well for up to 2 months. When ready to enjoy, thaw it overnight in the fridge and bake as usual for a freshly cooked taste.
What if my mashed potatoes are too runny or stiff?
No worries! If your mash is too runny, add a little extra butter or warm mashed potato flakes to firm it up. If it’s stiff, warm milk or cream, added gradually, will loosen it and bring back that silky smooth texture perfect for spreading over your pie.
Is Fish Pie with Potato Topping safe for pets?
While fish and potatoes are generally safe for dogs in moderation, this recipe includes butter, cream, and seasonings that could upset their stomachs. It’s best not to share this dish with pets or to check with your vet before offering any human food.
