Step 1

Preheat the oven to 200°C/fan180°C/gas Bring a pan of lightly salted water to the boil. Add the gnocchi and cook for 2-3 minutes, until cooked. (The gnocchi will float to the surface when they are ready.) Drain and reserve 250ml of the cooking water. Set aside.

Step 2

Melt the butter in a wide, deep frying pan and gently fry the leek for 3-4 minutes, until soft. Stir in the cream cheese, tomato purée, chilli flakes, lemon zest, parsley and reserved water, until the cheese has melted and everything is combined. Adjust the seasoning.

Step 3

Add the gnocchi and salmon to the frying pan and stir to coat. Spoon into a deep 1.2-litre ovenproof dish and bake in the oven for 15-20 minutes or until lightly golden on top. Serve immediately.
