Fish pie with cauliflower mash
750 g, cut into florets
baby spinach leaves
skinless salmon fillet(s)
500 g, cut into 3cm pieces
grated parmesan cheese
- Cook cauliflower in a large pan of boiling water for 8-10 minutes, or until completely tender. Drain and set aside in a colander for a few minutes to steam-dry. Transfer to a food processor with crème fraîche and blitz to a purée. Season and set aside.
- To make a white sauce, heat butter in a large deep frying pan over a medium heat until frothy. Add flour and stir well to make a paste. Cook over a low heat for 2 minutes, then gradually add the milk, stirring well between each addition, until you have a smooth sauce. Simmer gently for a few minutes, until the sauce thickens. Add mustard, and season well.
- Preheat the oven to 200°C. Wilt spinach briefly in the microwave, then squeeze out as much water as possible and add to the sauce, along with the fish. Fold gently to combine. Transfer to a 20cm x 26cm pie dish.
- Top with cauliflower mash, either piping it on in swirls using a piping bag fitted with a star nozzle, or forking over the surface to create a rough texture. Sprinkle with parmesan and bake for 20-25 minutes, then finish it off under a hot grill for 5 minutes to get a crisp, golden crust.
