Jamie Oliver Cheese and Potato Pie is a baked vegetarian pie made by layering sliced potatoes with cheese and a creamy sauce, then cooking it slowly until the potatoes are tender and the top is golden. It sits somewhere between a gratin and a pie, focusing on texture and gentle flavour rather than pastry.
Preheat your oven to 190°C (170°C fan). Lightly butter a medium baking dish so the pie doesn’t stick.
Slice the potatoes thinly and evenly. Even slices are essential so everything cooks at the same pace and the centre doesn’t stay firm.
Melt the butter in a saucepan over medium heat. Stir in the flour and cook for 1 minute, stirring constantly. Gradually whisk in the milk, then add the cream. Cook gently until the sauce thickens slightly. Season with salt, pepper, and a pinch of nutmeg or mustard powder if using.
Arrange a layer of potatoes in the baking dish, followed by a few slices of onion and a handful of grated cheese. Spoon over some sauce. Repeat the layers until everything is used, finishing with cheese and sauce on top.
Cover the dish loosely with foil and bake for 40 minutes. This allows the potatoes to soften without the top browning too quickly.
Remove the foil and return the dish to the oven for another 20–25 minutes, until the top is golden and the sauce is bubbling.
Remove the pie from the oven and let it rest for 10 minutes. This helps the layers settle and makes serving easier.
