Maris piper & winter greens gratin

Step by Step

Step 1

Preheat the oven to 200°C, gas mark 6. Bring a pan of salted water to the boil, then simmer the potatoes for 4-5 minutes until just tender; drain. While the potatoes are cooking, heat the oil in a large, lidded frying pan. Sauté the shallot until softened (about 5minutes), then add the garlic and fry for another minute until fragrant. Stir in the greens, cover and cook for 6-8 minutes until wilted. Season and set aside.

Step 2

Meanwhile, make the sauce. Melt the butter in a saucepan over a low heat, then add the flour and cook, stirring constantly, for 3-4 minutes until pale golden. Gradually whisk in the milk and stir until simmering, then take off the heat and stir in the nutmeg and ⅔ of each of the cheeses; season.

Step 3

Lay ½ the potatoes in a 1.8-2-litre baking dish and cover with the greens mixture. Top with the remaining potatoes and pour over the sauce. Finish with the remaining cheese and bake for 25 minutes or until golden and bubbling. Rest for 5 minutes before serving
