Ingredients
Scale
For the Sauce and Filling
- 1½ tbsp butter
- 3 tbsp flour
- 350ml full-fat milk
- 1–2 tbsp creamed horseradish (optional)
- Small bunch dill, chopped
- 1 large bunch spring onions, chopped
- Zest 1 lemon
- 2 x 175g packs smoked trout fillets, skin and bones removed, flaked into big chunks
For the Topping
- 450g leftover mashed potatoes
Instructions
- Preheat the Oven: Heat the oven to 200°C (180°C fan)/gas mark 6 to prepare for baking the pies.
- Make the Roux: Melt the butter in a medium saucepan over medium heat. Stir in the flour and cook for 1 minute to form a roux, ensuring the flour is fully combined but not browned.
- Add the Milk and Horseradish: Gradually stir in the full-fat milk and the creamed horseradish if using. Continue to stir and cook until the sauce bubbles and thickens, about 2 minutes.
- Mix in Flavorings and Fish: Add the chopped dill, three-quarters of the chopped spring onions, lemon zest, and flaked smoked trout to the sauce. Season with salt and pepper to taste and mix gently to combine all ingredients evenly.
- Assemble the Pie: Pour the fish mixture evenly into 4 individual pie dishes or one large pie dish. In a separate bowl, mix the leftover mashed potatoes with the remaining spring onions, then spoon this mixture over the fish filling to cover completely.
- Bake: Place the pie(s) in the preheated oven and bake for 15-20 minutes or until the topping is golden brown and the filling is bubbling around the edges.
- Serve: Remove from oven and allow to cool slightly before serving for a comforting and flavorful fish pie meal.
Notes
- You can substitute smoked trout with hot-smoked salmon or a combination of prawns and smoked salmon trimmings for variety.
- Using leftover mashed potatoes as the topping helps reduce food waste and adds a rich, creamy texture.
- If you prefer a milder flavor, omit the horseradish or adjust the quantity to taste.
- Pie dishes can be individual servings or a single large dish depending on your preference.
