Irish Fish Pie Recipe: Savory Cream Cheese Crust Over Flaky Pastry

This Irish fish pie recipe brings comfort food tradition to life with a flaky pastry crust and rich, creamy filling that tastes like a cozy pub dinner.

The secret lies in layering tender white fish with a velvety béchamel sauce, then sealing it all under a golden pastry that's crisp enough to cut with a fork.

I first tried this version during a rainy weekend in Portland, when I wanted to recreate the hearty flavors of my grandmother's Irish stew—but with a dish that would impress. The combination of flaky pastry and tender fish creates a texture that's both satisfying and elegant.

What makes this recipe special is the balance of traditional techniques with modern convenience. The filling uses fresh cod or haddock, simmered in white wine and herbs until just tender, then bound with a smooth béchamel that coats every bite.

The pastry gets its signature flakiness from cold butter and careful layering, while the cream cheese crust adds a subtle tang that cuts through the richness. It's the kind of dish that feels indulgent yet leaves you satisfied—not too heavy, not too light, but perfectly balanced.

By the time it emerges from the oven, you'll have a golden, bubbling pie with a crisp pastry shell and a filling that's creamy yet not overly rich.

The aroma alone will have everyone gathering at the table, while the first bite delivers layers of flavor: tender fish, savory herbs, and that buttery pastry that melts just slightly.

This is comfort food at its finest—warm, inviting, and packed with the kind of flavors that make you want to linger over seconds.

Serve with a simple green salad or steamed vegetables to balance the richness, and don't forget a cold pint of Guinness for the full Irish pub experience.

The leftovers reheat beautifully, making this the perfect make-ahead dish for family dinners or holiday gatherings. Let's get started on creating this classic with a modern twist.

Ingredients for irish fish pie

Pantry staples meet pub-style flavors in this classic Irish fish pie.

The fish is the star, so freshness matters. Cod and haddock both work—cod is firmer, haddock melts slightly. Grab them at Whole Foods or your local fishmonger if possible; the seafood counter usually has pre-cut fillets already cleaned. Look for fillets with a bright, translucent color and no fishy odor. If you're using frozen, thaw overnight in the fridge—never under running water, or they'll turn mushy. I always buy extra because it's so easy to portion for leftovers. For the white wine, Sauvignon Blanc adds a nice crispness, but any dry white will do.

No fresh dill? Dried dill at one-third the amount works, but fresh has way more flavor. Short on cream cheese? Substitute sour cream, though the texture won't be quite as smooth. The pie crust can be homemade if you're ambitious, but store-bought puff pastry saves time and still looks impressive. For the béchamel, don't skip the milk—it makes the sauce silky. Want extra richness? Add 1 tbsp of crème fraîche to the filling. The shallots are optional but add a lovely sweetness—skip them if you're in a hurry or don't have any on hand.

This pie reheats beautifully—just cover with foil and warm at 350°F for 15 minutes. Keeps in the fridge for 3 days and freezes for 2 months if you wrap it tightly. I always make a double batch because it's perfect for meal prep. The cream cheese crust gives it that signature tang, so don't skip it! Serve with a simple arugula salad and a cold Guinness for the full Irish experience.

Step-by-step instructions for Irish fish pie recipe

Here's how to build a rich, creamy fish pie with a golden crust that's crisp on top and tender underneath.

Cut the 2 lb fresh cod fillets and 1 lb haddock fillets into 1-inch chunks and place them in a large bowl. Add the 2 tbsp fresh lemon juice, 0.25 cup chopped fresh dill, 0.25 cup chopped fresh parsley, 4 minced garlic cloves, and 2 finely chopped shallots. Toss gently to coat the fish evenly. Sprinkle with 1.5 tsp salt and 0.5 tsp black pepper, mixing just until combined.

The lemon juice brightens the fish flavor while the herbs and garlic add depth. Don't overmix or you'll break up the delicate fish pieces. Let the mixture sit at room temperature for 15 minutes while you prepare the sauce—this helps the flavors meld before cooking.

In a medium saucepan, melt the 0.75 cup unsalted butter over medium heat. Once melted, whisk in the 0.5 cup all-purpose flour to form a smooth paste. Cook for 1-2 minutes until the mixture bubbles and smells toasty—this removes the raw flour taste.

Gradually whisk in the 1.5 cups heavy cream and 0.5 cup whole milk, stirring constantly to prevent lumps. Add the 8 oz softened cream cheese and 0.5 cup dry white wine, whisking until fully melted and smooth. Reduce heat to low and simmer for 5 minutes until the sauce thickens slightly. Remove from heat and stir in 1 tbsp fresh lemon juice to balance the richness.

Pour the warm sauce over the fish mixture in the bowl and gently fold together until the fish is fully coated. The sauce should be thick enough to hold its shape when spooned—if it's too thin, simmer it for another 2-3 minutes to reduce slightly. Transfer the mixture to a 9x13-inch baking dish and spread it into an even layer.

Here's the thing—don't pack the filling down. You want it to stay fluffy so it holds its texture when baked. If the sauce looks too thick, whisk in 1-2 tablespoons of water to loosen it just enough to coat the fish properly.

In a separate bowl, beat the 1 whole egg yolk until frothy. Add the 8 oz cream cheese that wasn't used in the sauce (yes, you'll need all of it) and mix until smooth. Spread this mixture evenly over the top of the fish filling in the baking dish, creating a ¼-inch thick layer. The goal is full coverage—no gaps where the crust meets the filling.

This cream cheese layer is what makes this pie uniquely Irish—it adds a velvety texture that contrasts beautifully with the flaky pastry. Don't worry if it looks messy; we'll seal it with the pie crust next.

Unroll the 1 sheet store-bought pie crust and place it over the cream cheese layer. Press gently to adhere, then trim any excess crust hanging over the edges. Cut 4-5 small slits in the center to allow steam to escape during baking. Brush the crust with the remaining 1 tbsp egg yolk mixed with 1 tablespoon water for a golden finish.

Bake in a preheated 375°F oven for 35-40 minutes until the crust is deep golden brown and the filling is bubbling at the edges. The pie is done when the crust is crisp and the center is just set—it should jiggle slightly when shaken. Let it rest for 10 minutes before serving to allow the filling to set properly.

Slice the pie into 6 equal portions and serve immediately with 0.25 cup Guinness stout on the side. The stout's malty notes complement the rich fish and creamy sauce perfectly. For extra flakiness, broil the pie for 1-2 minutes before serving if you prefer a deeper golden crust.

Each bite should deliver tender fish, velvety cream cheese, and crisp pastry—all the elements that make this Irish classic so satisfying. The pie tastes even better the next day, so make extra if you can!

Creative variations of these flavors

Pub-Style Guinness Twist

For a true Irish pub experience, replace the white wine in the sauce with ½ cup Guinness stout and reduce it by half before adding the cream cheese. The malty depth enhances the fish flavor beautifully.

I tested this version after a trip to Dublin and it became my go-to—just add 1 tbsp brown sugar to balance the bitterness. Serve with extra stout for dipping, because why not? 🍺

Vegetarian Adaptation

Swap the fish for 1 lb king oyster mushrooms or 2 cups chopped hearts of palm, both of which absorb flavors like fish. Sauté them in olive oil with garlic and lemon juice until tender before mixing with the sauce.
