How to Make Baked Fish Pie with Herbed Mash
- Preheat Oven: Preheat your oven to 375°F and butter a deep-dish pie plate. This step ensures even baking and a non-stick surface for the pie.
- Boil Potatoes: Peel and quarter potatoes, then place in salted water. Boil until fork-tender, about 15 minutes. This yields fluffy texture ready for herbed mash.
- For the Mash: Drain potatoes, then mash with butter, warmed milk, and fresh herbs until smooth and fluffy. Season generously with salt and pepper, then set aside.
- Sauté Aromatics: In a skillet, melt butter and gently sauté onions and garlic over medium heat until soft and translucent, about 3 minutes. This builds savory depth.
- Make Sauce: Stir in flour, cook 1 minute, then gradually whisk in milk until creamy. Simmer for 2 minutes until thick. Stir in Dijon mustard, lemon juice, and parsley.
- Fold in Fish: Gently stir in white fish and smoked fish chunks into the creamy sauce. Cook just until fish turns opaque, about 1–2 minutes. Remove from heat.
- Assemble Pie: Spoon the fish filling into the prepared dish, then dollop mashed topping over all. Use a fork to create peaks for golden edges.
- Bake Pie: Place pie on middle rack, bake at 375°F for 20–25 minutes until mash is golden brown and bubbling around edges. Let rest 5 minutes.

The herbed mash can also be made a day ahead—just turn it into a smooth, fluffy topping and store it in an airtight container in the fridge.

Baked Fish Pie with Herbed Mash Recipe FAQs
How do I know if my fish is fresh enough for the pie?
Look for firm, translucent flesh that springs back when touched. Avoid fish with dark spots all over or a strong fishy odor, which can indicate it’s past its prime. Fresh white fish like cod or haddock should smell mild and sea-fresh.
Can I store leftover baked fish pie, and for how long?
Absolutely! Store leftovers in an airtight container in the fridge for up to 3 to 4 days. Make sure it’s cooled completely before sealing to keep the flavors vibrant and the texture just right.
Is it possible to freeze this fish pie, and what’s the best way?
Yes, I recommend freezing if you want to save pie for later. First, let the pie cool completely after baking. Wrap it tightly in plastic wrap followed by a layer of foil to prevent freezer burn. Label and freeze for up to 3 months. When ready to enjoy, thaw overnight in the fridge, then reheat in a 350°F oven for about 20–25 minutes until warmed through.
My mashed potato topping turned a bit watery; how can I fix that next time?
This can happen if the potatoes are overcooked or if too much milk is added. Next time, drain potatoes thoroughly before mashing and warm your milk or cream before mixing it in gradually. Also, be sure to use starchy potatoes like Russets for a fluffier, less watery mash.
Can I make this fish pie if I have dietary restrictions or pets at home?
For allergies, check the fish types carefully; cod and haddock are mild but always confirm no one is allergic to seafood or dairy. This pie isn’t suitable for pets due to onions, garlic, and dairy, which can be harmful. If you want a pet-friendly option, keep their meals separate from this delicious homemade dish.
