Individual Seafood Pot Pie (Irish Fisherman's pie)

If you're craving a cozy seafood pot pie that feels both traditional and fresh, this Irish pie or fish pie recipe is the one to make. Unlike the classic fisherman's pie that turns soft and spoonable, this version keeps tender chunks of white fish and shrimp intact beneath a creamy leek and spinach sauce, all tucked under fluffy mashed potatoes. Baked as an individual pot pie, it delivers perfect portions and beautiful texture - the kind of comforting, golden-topped dish that makes you want to pull it straight from the oven and dive in.

If you've searched for seafood pot pie, fish pie recipe, or traditional Irish Fisherman's pie, you've likely seen the classic method: poach the fish in milk, use the milk to make the sauce, then fold the fish back in.

After traveling through Ireland and tasting fish pies in cozy pubs along the way, I was inspired to recreate that comforting dish at home. But once I began researching, I struggled with the traditional technique. Poaching the fish first often left it soft, spoonable, and barely recognizable in the final pie.

I wanted something different.

This Individual Seafood Pot Pie keeps the fish intact - tender chunks of cod or haddock nestled in a creamy leek and spinach sauce, topped with fluffy mashed potatoes. No pre-poaching. No fussy steps. Just beautiful texture and clean flavors.

Baked in individual ramekins, it's perfectly portioned for a dinner for two. With Lent upon us and St. Patrick's Day around the corner, this Irish-inspired seafood pie feels especially fitting. And because it's loaded with vegetables, it truly is a meal in a pot.

The Origins of Fisherman's Pie in Ireland

Fisherman's pie - often simply called fish pie in Ireland - has deep roots in coastal Irish cooking. In a country surrounded by the cold, fish-rich waters of the Atlantic, seafood has long been a staple, especially in seaside villages where the daily catch determined supper.

Historically, Irish fish pie developed as a practical, economical dish. White fish like cod and haddock were abundant and affordable along the coast. Cooks would stretch the catch by folding it into a simple white sauce and topping it with mashed potatoes - a nod to Ireland's most iconic crop. The result was hearty, warming, and designed to feed families well using what was readily available.

It's closely related to shepherd's pie and cottage pie, but instead of lamb or beef, fisherman's pie celebrates the sea. Over time, versions evolved to include smoked haddock, shrimp, or even salmon, depending on the region and the season. In pubs across Ireland, fish pie became a comfort classic - creamy, sustaining, and perfect alongside a pint on a blustery evening.

What I love most is how this humble Irish pie reflects the heart of traditional Irish cooking: simple ingredients, thoughtfully prepared, turning everyday staples into something deeply comforting.

Choosing the Right Fish for Irish Fisherman's Pie

The best fish for seafood pot pie are firm, white-fleshed varieties that hold their shape during baking. They should be mild enough to absorb the flavors of the sauce without overpowering it.

If possible, ask your fishmonger to remove skin and pin bones. Then simply cut into ½-inch chunks.

Top Choices for Fish Pie:

• Cod - A classic choice, firm and flaky
• Haddock - Similar to cod but slightly more delicate
• Halibut - Thick and meaty
• Red Snapper - Slightly sweet and firm
• Sea Bass - Mild and structured
• Mahi-Mahi - Very firm, great for hearty dishes
• Monkfish - Dense, sometimes called "poor man's lobster"
• Grouper - Dense and substantial

For a true seafood pie, I like using haddock or cod plus shrimp (or prawns) for sweetness and texture contrast.

How to Make a Individual Seafood Pot Pie

Step 1: Build the Vegetable Cream Base

In a large pan over low heat, melt the butter. Add onion, carrot, and leek with a generous pinch of salt (photo 1).

Cook slowly for about 10 minutes, stirring occasionally, until soft and translucent - not browned.

Stir in heavy cream, Dijon mustard, soy sauce and lemon juice (photo 2).

Add spinach in batches, letting each handful wilt before adding more. Simmer gently 2-3 minutes until bright green and just tender (photo 3). Season with salt and pepper.

This becomes the creamy vegetable layer that carries the whole pie.

Step 2: Layer the Seafood

Because we don't pre-poach the fish, it stays intact and flaky after baking.

Step 3: Top with Perfect Mashed Potatoes

Step 4: Bake

Place ramekins on a baking sheet to catch drips. Bake at 375°F until the top is golden and the filling is bubbling. This will take about 30 minutes. If putting in the oven strait from the refrigerator add about 10-ish more minutes.

For extra browning, broil for 2-3 minutes at the end.

Perfect Irish Mashed Potatoes

To make the "Irish Mash" topping for two 16 ounce individual fish pies, you will need:

• 1.5 to 2 pounds potatoes, like Yukon gold potatoes, peeled and cut into even chunks.
• 2 tablespoons butter
• ¼ cup milk
• Sea salt and black pepper

Tips for Perfect Mash

1. Cook through completely - undercooked potatoes = lumps.
2. Steam rather than boil if possible. Boiling can waterlog potatoes and create soupy mash.
3. Measure butter and milk. Too much makes it sloppy; too little makes it dry.

Place potatoes in steamer and steam potatoes about 30 minutes until fully tender. If you decide to boil the potatoes, keep a close eye on them so they do not become waterlogged.

Heat butter and milk together until melted in a large enough saucepan to mash the potatoes. Add potatoes to the butter mixture, along with some salt, pepper, ½ teaspoon chopped dill, and a pinch of lemon zest. Give them a good mash until they are smooth and fluffy.

Perfect for fish pie topping.
