Boulangère potatoes

Omit the anchovies if you’re not a fan, though by the time you serve this dish, you’d hardly know they were there – they practically melt into the potatoes, imparting a gorgeously salty flavour.

Serves: 6

Ingredients

• 50g unsalted butter, plus extra for greasing

• 350ml chicken stock

• 1 onion, finely sliced

• 2 garlic cloves, finely sliced

• 4 anchovy fillets, chopped

• 1.2kg maris piper potatoes, peeled and sliced as thinly as possible

• 2 tbsp thyme leaves

• large pinch freshly grated nutmeg

Method

1. Preheat the oven to 180˚C, gas mark 4; grease a 1.75–2 litre ovenproof baking dish. Heat the stock in a small saucepan; simmer for about 10 minutes until reduced by half. Meanwhile, melt 30g butter in a large pan, add the onion, garlic and anchovies; sauté for 5 minutes until soft.

2. Add the potatoes and cook for another 2–3 minutes, then stir in the thyme and nutmeg; season. Tip into the baking dish. Pour over the stock and dot with the remaining butter. Bake for 1 hour until the potatoes are tender and golden on top.
