Crafted with care and layered for maximum taste, this recipe transforms simple ingredients into an oven-baked masterpiece that delivers richness, texture, and nostalgic comfort in every spoonful.
Why This Fish Pie with Cheese Mash Stands Apart
The Hairy Bikers’ fish pie excels because it respects classic technique while embracing hearty generosity. The fish is gently poached in milk with aromatics, ensuring delicate flakes and a sauce infused with subtle onion and bay.
The topping—creamy mashed potatoes enriched with butter, milk, and mature Cheddar—adds a golden crust that contrasts beautifully with the velvety filling beneath.
This dish is also remarkably practical. It can be assembled ahead of time, refrigerated, and baked when needed, making it ideal for entertaining, family dinners, or relaxed weekend cooking.

Step-by-Step Method for Perfect Results
Infusing and Preparing the Fish
We begin by gently heating whole milk with thickly sliced onion and bay leaves, seasoning lightly. The fish fillets are introduced and brought just to a whisper of a simmer before being covered and rested off the heat.
This method protects the fish’s tenderness while allowing the milk to absorb delicate flavors that will later define the sauce.
Once infused, the fish is drained and set aside, while the aromatic milk is reserved—this becomes the foundation of the pie’s signature creaminess.
Creating the Creamy Cheese Mash
Potatoes are simmered until soft, then drained thoroughly to avoid excess moisture. We mash them with butter, milk, and most of the grated Cheddar, seasoning carefully to achieve a smooth, savory topping. The inclusion of cheese within the mash adds depth, while the remaining Cheddar ensures a crisp, golden crust during baking.
Building the Silky Fish Pie Sauce
Butter is melted and combined with flour to form a pale roux. The infused milk is added gradually, stirred constantly to achieve a smooth, lump-free sauce.
A brief simmer thickens the mixture to the ideal consistency before peas are folded in. The result is a sauce that coats each ingredient without overwhelming the fish.
Layering for Maximum Flavor and Texture
The assembly is key to this dish’s success. A base layer of sauce cushions the fish, followed by chunks of flaky fillets and plump prawns.
Additional sauce ensures even moisture, while repeating the layers distributes flavor throughout the dish. The cheese mash is spread evenly on top, forked to create texture, and finished with a generous sprinkling of Cheddar.
This thoughtful layering ensures every portion delivers balanced bites of fish, sauce, and mash.
Baking to Golden Perfection
The assembled pie is baked at a high temperature until the top turns golden-brown and irresistibly crisp, while the filling bubbles gently beneath. Resting the dish briefly after baking allows the layers to settle, making serving easier and enhancing overall texture.
Make-Ahead and Storage Tips
One of the great advantages of The Hairy Bikers’ fish pie with cheese mash is its flexibility. The pie can be prepared up to 24 hours in advance and stored in the refrigerator. When ready to serve, it can be baked directly from chilled, adding only a few extra minutes to the cooking time.
Leftovers keep well for up to two days and reheat beautifully, making this dish a smart choice for meal planning.
Serving Suggestions and Pairings
We recommend serving this fish pie with lightly buttered seasonal greens, steamed broccoli, or a crisp green salad dressed with lemon. These accompaniments cut through the richness and refresh the palate, creating a complete and satisfying meal.
For drinks, a dry white wine or sparkling water with citrus complements the creamy sauce without overpowering it.
Nutritional Balance and Comfort Appeal
This dish offers a well-rounded nutritional profile. The fish and prawns provide high-quality protein, while peas contribute fiber and vitamins. Potatoes deliver comforting carbohydrates, and the dairy elements add calcium and richness. It is indulgent yet nourishing, making it a perfect choice for family dining.
