Ingredients:
1 tbsp olive oil
1 tbsp butter, plus more for the dish
1 onion, finely chopped
3oz (85g) sliced pancetta or bacon, chopped
1lb (450g) spinach leaves, washed
1⁄2 cup crème fraîche or heavy cream
1⁄2 cup freshly grated Parmesan
salt and freshly ground black pepper
13⁄4lb (800g) finnan haddie (smoked haddock), skinned
juice of 1⁄2 lemon
1⁄2 cup fresh bread crumbs

method
1 Preheat the oven to 375°F (190°C). Butter an oven-proof serving dish. Melt the oil and butter together in a frying pan over medium-high heat. Add the onion and pancetta and cook until lightly browned, about 5 minutes.

2 In batches, stir in the spinach and cook until wilted. Stir in the crème fraîche and 6 tbsp of the Parmesan. Season with salt and pepper and simmer until it has thickened slightly.

3 Spoon the spinach mixture into the dish. Place the finnan haddie on top. Sprinkle with lemon juice.

4 Mix the bread crumbs and remaining 2 tbsp Parmesan and sprinkle over the fish. Bake for 15–20 minutes, or until the fish is hot.
