Instructions
Step 1: Preheat the Oven
Begin by setting your oven to 450°F (230°C). This high temperature ensures that the top layer of mashed potatoes will develop a beautiful, crispy golden crust, providing both a visual appeal and a delightful textural contrast. Proper preheating is crucial for even baking and achieving the desired crust, especially since the dish is assembled cold or at room temperature.
Step 2: Prepare the Baking Dish
Select an 8×8 inch (20×20 cm) baking dish with a depth of around 2 inches. Lightly butter the dish with a small amount of butter or non-stick spray to prevent sticking and facilitate easy cleanup. Place the prepared dish on a cookie sheet or baking tray. The tray serves as a safety measure to catch any sauce that might bubble over during baking, preventing messes in your oven and making cleanup more manageable.
Step 3: Prepare the Cod Fillets
Pat the cod fillets dry using paper towels to remove excess moisture, which helps in even cooking and better adhesion of seasonings. If using frozen fillets, ensure they are fully thawed in the refrigerator for at least several hours or overnight. Once thawed, check for any bones and remove them with tweezers. Season the fillets lightly with salt and pepper on both sides to enhance flavor. For an extra layer of flavor, consider sprinkling a little paprika or lemon zest if desired.
Step 4: Arrange the Fish in the Dish
Place the seasoned cod fillets in a single layer at the bottom of the prepared baking dish. Ensure they are evenly spaced to allow the cheese sauce to envelop each piece uniformly. For added flavor, you can layer sliced onions, leeks, or herbs like thyme or parsley underneath or over the fish.
Step 5: Make the Cheese Sauce
In a medium saucepan, melt 2 tablespoons of butter over medium heat. Once melted, add the flour and whisk vigorously to combine, creating a smooth roux. Cook this mixture for about 2 minutes, stirring constantly, to eliminate the raw flour taste and to develop a slightly nutty aroma. Gradually pour in 2 cups of milk, whisking continuously to avoid lumps. Increase heat slightly and cook, stirring constantly, until the sauce thickens and reaches a creamy consistency—this might take about 5-7 minutes.
Once the sauce is thickened, remove from heat and stir in the grated cheese until fully melted and smooth. Season with additional salt and pepper if needed. For a flavor boost, consider adding a pinch of smoked paprika, a dash of mustard powder, or chopped herbs like chives or parsley. For a more robust flavor, stir in sliced scallions after removing the sauce from heat, especially if garnishing later.
Step 6: Assemble the Pie
Pour the cheese sauce evenly over the cod fillets, ensuring each piece is well coated. Use a spatula or the back of a spoon to gently spread the sauce and cover all the fish, creating a uniform layer that will bake into a luscious topping. This step is crucial because it helps keep the fish moist and infuses it with cheesy goodness during baking.
Step 7: Prepare the Mashed Potato Topping
Spoon the prepared mashed potatoes over the cheese-covered fish. Use a spatula or the back of a large spoon to spread the mashed potatoes evenly across the surface. For a more decorative finish, you can pipe the mashed potatoes using a piping bag fitted with a star tip, creating ridges or rosettes that will crisp up beautifully.
Dot the surface with small pieces of butter (about 4 tablespoons total) to add richness and promote browning. For added flavor, sprinkle a little grated cheese, paprika, or chopped herbs on top of the mashed potatoes before baking.
Step 8: Bake the Irish Cod Pie
Transfer the assembled dish to the preheated oven. Bake for approximately 25-30 minutes, or until the top is golden brown and crispy, and the sauce is bubbling around the edges. If the top browns too quickly, loosely tent with aluminum foil to prevent burning while allowing the dish to cook through.
Allow the pie to rest for about 5 minutes after removing from the oven. This resting period helps the layers set, making it easier to serve neat slices and preventing the hot cheese sauce from spilling out.
Step 9: Garnish and Serve
For a fresh finishing touch, sprinkle sliced scallions over the top just before serving. You may also add a squeeze of fresh lemon juice to brighten the dish’s flavors. Serve hot, accompanied by side dishes like crusty Irish soda bread, steamed vegetables, or a crisp green salad.
Preparation Tips
- Choosing the right fish: Fresh cod is ideal for its firm texture and mild flavor, but high-quality frozen fillets work well if thawed properly. Ensure fish is cooked just until opaque and flaky to prevent dryness.
- Cheese selection: Sharp cheddar provides a bold flavor, but combining it with Gruyère or Parmesan can add depth. Use grated cheese for easy melting.
- Making perfect mashed potatoes: For extra creamy mashed potatoes, add a splash of cream or butter during mashing. For flavor variations, incorporate roasted garlic, cooked cauliflower, or herbs.
- Layering: For a more visually appealing dish, consider layering the fish, sauce, and mashed potatoes in a specific order to create distinct layers when sliced.
- Cooking the sauce: Whisk continuously during the milk addition to prevent lumps. If lumps form, strain the sauce through a fine sieve before proceeding.

Tips and Tricks

Save and Store
Allow the baked Irish Cod Pie to cool completely before storing. Cover tightly with plastic wrap or aluminum foil and refrigerate for up to 2 days. To reheat, place slices in an oven-safe dish and warm at 350°F (175°C) for 15-20 minutes, or until heated through. For best results, reheat uncovered to maintain the crispy topping.
You can also freeze individual portions for up to 3 months. Wrap tightly in plastic wrap and then foil. Thaw overnight in the refrigerator before reheating in the oven.
FAQ
Can I use other types of fish?
Yes, firm white fish like haddock, pollock, or hake can be substituted for cod. Adjust cooking times slightly if the fillets are thicker or thinner.
How do I prevent the mashed potatoes from becoming watery?
Ensure your mashed potatoes are well-drained and fully cooked. Adding a bit of butter or cream during mashing can help improve their consistency. Using starchy potatoes like Russets or Yukon Golds yields fluffier results.
Can I make this dish dairy-free?
Use plant-based milk (such as almond, soy, or oat milk) and dairy-free cheese alternatives. Keep in mind that flavor and melting properties may differ.
How do I get a crispy top?
Ensure the buttered mashed potatoes are evenly spread and dot with extra butter. Baking at a high temperature and possibly broiling for a couple of minutes at the end can also enhance crispiness.
