Mary Berry Cheese and Potato Pie

Mary Berry Cheese and Potato Pie

Mary Berry Cheese and Potato Pie is a traditional British baked dish made with layers of cooked potatoes, a creamy cheese sauce, and a golden top. It sits somewhere between a gratin and a pie, offering comfort without pastry. Think of it as the savoury version of a slow, reassuring hug—nothing rushed, nothing sharp, just steady satisfaction.

Ingredients

  • Potatoes – 1 kg, peeled and sliced

  • Cheddar cheese – 200 g, grated

  • Milk – 300 ml

  • Butter – 40 g

  • Plain flour – 40 g

  • Onion – 1 medium, finely chopped

  • Salt – 1 tsp (adjust to taste)

  • Black pepper – ½ tsp

  • Mustard (optional) – 1 tsp

Instructions

  • Cook the potatoes – Boil sliced potatoes in salted water until just tender, then drain well

  • Make the sauce – Melt butter, add onion, cook gently, then stir in flour to form a roux

  • Add the milk – Gradually whisk in milk until smooth and thick

  • Stir in cheese – Add most of the grated cheese, seasoning, and mustard if using

  • Assemble the pie – Layer potatoes in the dish and pour over the cheese sauce

  • Finish and bake – Sprinkle remaining cheese on top and bake until golden and bubbling
