Chicken Parmentier recipe

Ingredients

For the potato topping

• 1.5kg/3lb 5oz floury potatoes, such as King Edwards, peeled
• 30g/1oz butter
• Five tbsp double cream
• Two free-range egg yolks
• salt and black pepper

Instructions

For the topping:

Boil the potatoes in salted water until they are tender. Drain them and either push through a potato ricer or mash thoroughly. Mix in the butter, cream, and egg yolks. Season to taste and set aside.

For the filling:

Melt the butter in a large pan. Add the shallots, carrots, and celery, and cook gently until they are soft. Then add the garlic. Pour in the wine and cook for 1 minute. Stir in the tomato purée, chopped tomatoes, and stock, and let it simmer for 10–15 minutes until it thickens. Add the shredded chicken, olives, and parsley. Season with salt and pepper.

Preheat the oven to 180C/160C Fan/Gas 4.

Transfer the filling to a 20x30cm/8x12in ovenproof dish and spread the mashed potatoes over the top. Sprinkle with grated Gruyère. Bake for 30–35 minutes, until the dish is piping hot and the potato topping is golden-brown.
