Ingredients on a plate to make a luxurious British fish pie with cheesy mashed potato recipe

To make this luxury fish pie use a combination of at least two types of fish and vary this according to what is seasonally and sustainably available. Add shellfish to make it more luxe but it is equally as nice with only fish. If you omit the prawns, just add more salmon/trout.

I like a combination of smoked fish and white fish and if I’m trying to be extra fancy, salmon or salmon trout (more affordable sustainable and readily available).

Bite sized pieces of mixed seafood to make a luxurious British fish pie with cheesy mashed potato

A British fish pie is one of my ultimate dishes and Jamie Oliver’s fantastic fish pie is a firm family favourite around here. His recipe calls for hard-boiled eggs which is a British classic and you can of course add it to this fish pie recipe if you prefer. A large handful of baby spinach leaves or peas could work too.

This fish pie recipe was created to pair with the Ladybird Chardonnay 2022.

Here is a little more about this delicious organic wine from Stellenbosch which is made exclusively for Woolworths.


2022 was a much cooler and later vintage than average, the slow ripening conditions resulted in an exceptional vintage for our estate with concentrated fruit development and palate weight. All our grapes are farmed organically and are estate grown.


The grapes were handpicked in the early morning the whole bunches were pressed with no additions to the juice. 30 % of the wine is fermented in new oak barrels, while the remaining 70% is in concrete eggs. The wine undergoes natural fermentation and stays on the lees for 8 months after fermentation is completed. No sulphur is added. We chose to use less oak in this vintage to express freshness and pure Chardonnay fruit. The wine is filtered before bottling.


Lovely, light straw colour with a slight green tint. A complex nose with hints of fresh hay, citrus, pineapple, white nectarine, butterscotch and caramelised toffee. A juicy fresh palette with loads of fruit, well supported with lingering lime-like acidity. A fresh, light, charming and hugely enjoyable wine. A perfect wine to enjoy on its own, but will complement many summer lunchtime dishes such as salads, gourmet sandwiches, sushi, quiche, and grilled calamari.

How to make a Luxurious fish pie with cheesy mash

  • Start off by boiling your potatoes in a large pan of boiling salted water until knife tender. Drain and allow the steam to further evaourate and dry any excess moisture out the potatoes a little more.
  • Prepare your seafood by cleaning and cutting it into appropriate sizes. The prawns will not need to be cut unless they are very big.
  • Poach the smoked fish in warm milk with bay leaves and fish stock. Add this to the rest of the fish in the pie dish.
  • Make the creamy sauce by first softening the onion and celery in the butter until translucent. Then add the flour to make a roux. Slowly add the hot milk until it is fully absorbed.
  • Add the lemon zest, juice, cream (or double cream), vermouth (or wine), and fresh herbs. Once incorporated add the cheese and adjust the seasoning with salt and white pepper to taste.

What to top a classic British fish pie with

Mashed potato is the classic topping for a British fish pie but you could get creative with any of  these toppings too:

  1. Scalloped potato which will form a layered topping. Brush a splash of cream between the layers to separate them.
  2. Make a parsley crumb or other herb and bread crumb mixture for a lighter fish pie topping.
  3. A potato rosti topping with grated potato could be a delicious and crispy topping. Toss the shredded potato with cream and butter.
  4. Puff pastry is another less traditional topping idea that works very well.

  • Dollop the mashed potato onto the fish pie filling and gently spread it to ever the surface. Brush the top of the pie with additional melted butter. if you wanted to be fancy, you could put the mashed potato into a piping bag and pipe pretty swirls.

Make sure you put a baking tray under the fish pie whilst baking as the sauce could bubble and leak out.
