A Hug in a Casserole Dish: My Beloved Fish and Potato Pie

There are some dishes that, with a single whiff, transport you back in time. For me, that dish is Fish and Potato Pie. I vividly remember my friend Sarah, a truly gifted home cook, presenting this golden-baked marvel one chilly autumn evening. The aroma of melting cheese, comforting potatoes, and savory fish filled her cozy kitchen, promising something deeply satisfying. It was more than just a meal; it was an embrace, a testament to the simple joy of good food shared. That night, I knew I had to capture that magic, and after some friendly recipe sharing and a bit of my own culinary tinkering, I believe I’ve finally done it justice.

This comforting pie brings together the delicate flavour of fish with a creamy sauce and a hearty potato topping. It’s a straightforward dish that delivers maximum flavour and satisfaction.

• 1 tablespoon lemon juice
• Salt and pepper to taste

For the Topping:

• 2 lbs potatoes, peeled and boiled
• 1 tablespoon milk
• 4 ounces cheddar cheese, grated
• 2 tablespoons grated Parmesan cheese
• 1 ounce butter
• 1-2 medium tomatoes, sliced to place on top

Equipment Needed

To bring this wonderful pie to life, you’ll want to have a few key pieces of equipment ready:

• A large pot for boiling potatoes
• A potato masher or ricer
• A medium frying pan or wok
• A casserole dish (approximately 1.5-litre capacity is ideal)
• A baking dish or ovenproof serving dish for the final pie

Instructions

Let’s get cooking! This recipe is designed to be approachable, ensuring a delicious outcome even for novice cooks.

1. Begin by preparing the potatoes for the topping. Peel the potatoes, cut them into even-sized chunks, and place them in a large pot. Cover with cold water, add a pinch of salt, and bring to a boil. Cook until the potatoes are completely tender when pierced with a fork, which should take about 15-20 minutes depending on their size.
2. Once the potatoes are tender, drain them thoroughly and return them to the hot, dry pot. Allow any residual moisture to evaporate for a minute or two over low heat. Add the 1 ounce of butter and 1 tablespoon of milk to the pot. Mash the potatoes until smooth and creamy, or to your desired consistency. Stir in the 4 ounces of grated cheddar cheese and mix well until the cheese is melted and incorporated into the mash. Season with salt and pepper to your liking. Set this aside.
3. While the potatoes are boiling, prepare the fish filling. In a medium frying pan or wok, melt the remaining 1 ounce of butter over a medium heat. Add the finely chopped onion and sauté gently until it becomes soft and translucent, about 5-7 minutes. Be careful not to brown it too much; we want a sweet, softened onion flavour.
4. Add the minced garlic to the pan with the onions and cook for another minute until fragrant. Be mindful not to burn the garlic.
5. Now, add the chunks of smoked haddock or cod to the pan. Gently break them up slightly with your spoon if they are very large, but you want to retain some texture. Pour in the ½ pint of single cream and stir in the finely chopped fresh parsley and 1 tablespoon of lemon juice.
6. Season the fish mixture generously with salt and pepper. Stir everything together gently and allow it to simmer for about 5 minutes, just long enough for the fish to begin flaking and the cream to thicken slightly. The fish should be cooked through but still moist.
7. Preheat your oven to a medium heat (approximately 180°C / 350°F / Gas Mark 4).
8. Spoon the prepared fish filling into the bottom of your casserole dish, spreading it out evenly.
9. Carefully spoon the cheesy mashed potato topping over the fish filling, covering it completely. You can spread it smoothly with a spatula or create some peaks and swirls with a fork for a more rustic appearance.
10. Sprinkle the 2 tablespoons of grated Parmesan cheese evenly over the top of the potato layer.
11. Arrange the sliced tomatoes attractively on top of the Parmesan cheese.
12. Dot the remaining ½ ounce of butter over the top of each tomato slice. This will help them soften and brown slightly during baking.
13. Place the assembled pie into the preheated oven and bake for 40-50 minutes. You’re looking for the topping to be golden brown and slightly crisp, the filling to be bubbling around the edges, and the tomatoes to be tender.
14. Once baked to perfection, remove the pie from the oven and let it rest for a few minutes before serving.

Expert Tips & Tricks

• Potato Perfection: For the smoothest mash, use a potato ricer. If you don’t have one, ensure you mash the potatoes while they are still hot, as they are easier to work with and will absorb the butter and milk more readily. Don’t overwork the mash, or it can become gluey.
• Fish Matters: While smoked haddock offers a wonderful depth of flavour, cod is a great alternative for a milder taste. Ensure your fish is fresh and free from bones and skin for the best texture. If using cod, you might want to add a pinch of smoked paprika to the filling for a subtle smoky note.
• Creamy Dreamy: Single cream is ideal here for its richness without being too heavy. If you can’t find single cream, you can use double cream diluted with a little milk, or even half-and-half.
• Browning Bonus: If your topping isn’t browning as much as you’d like by the end of the cooking time, you can briefly place the pie under the grill (broiler) for a minute or two, keeping a very close eye on it to prevent burning.
• Make Ahead Magic: You can prepare the potato topping and the fish filling separately up to a day in advance. Store them in the refrigerator. When ready to bake, assemble the pie and bake as directed, you may need to add a few extra minutes to the cooking time if assembling from cold.

Serving & Storage Suggestions

This Fish and Potato Pie is a complete meal in itself, but it pairs beautifully with a simple green salad dressed with a sharp vinaigrette to cut through the richness. For a heartier meal, some steamed greens like broccoli or peas make a lovely accompaniment. Serve hot, straight from the oven, allowing the golden topping and the bubbling filling to impress.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, gently warm portions in the oven at a moderate temperature (around 160°C / 325°F) until heated through, or use a microwave, being mindful that the potato topping might lose some of its crispness.

Variations & Substitutions

• Herbal Notes: Feel free to experiment with other fresh herbs like chives or dill in the filling. A pinch of nutmeg in the potato topping can also add a lovely warmth.
• Cheesy Variations: While cheddar is a classic, a mature Gruyère or a sharp Red Leicester would also be delicious in the potato topping. For an extra umami kick, add a spoonful of English mustard to the mash.
• Vegetable Boost: You can add finely diced leeks or peas to the fish filling for extra flavour and texture.
• A Touch of Spice: For those who enjoy a hint of heat, a pinch of cayenne pepper or a small finely chopped chili could be added to the onion and garlic mixture.

FAQs

Q: Can I use a different type of fish?
A: Absolutely. While smoked haddock and cod are recommended, other firm white fish like haddock (unsmoked), pollock, or even salmon (though it will change the flavour profile) can be used.

Q: My potato topping seems a bit dry. What can I do?
A: If your mash feels too dry, add a little more milk or butter until it reaches your desired creamy consistency. Ensure the potatoes are thoroughly drained before mashing.

Q: How can I make the potato topping crispy?
A: For extra crispiness, try making shallow indentations with a fork all over the potato topping before baking. You can also finish the pie under the grill for a minute or two, watching it closely.

Q: Can I make this without cream?
A: While cream provides the signature richness, you could experiment with a good quality evaporated milk or a full-fat coconut milk for a dairy-free alternative, though the flavour will be altered.

Q: How long does it take to bake?
A: The pie generally bakes for 40-50 minutes, but always check for visual cues: a bubbling filling and a golden-brown topping.
