SAUCE FOR SCALLOPED POTATOES RECIPES

Steps:

• Heat the oven to 180C/160C fan/gas 4 and butter a deep 20 x 30cm baking dish. Melt the butter in a pan over a medium heat and cook the onion and garlic with a pinch of salt for 8-10 mins until the onion has softened slightly. Tip in the flour, stir well, then cook for a few minutes more. Mix the milk and stock together, then gradually pour this in, whisking well between additions until everything is incorporated and you have a smooth sauce. Simmer for a few minutes, then season well.
• Lay half the sliced potatoes in a single layer in the buttered dish, slightly overlapping them if needed. Pour over half the sauce, then scatter over half the parmesan. Arrange the remaining potatoes on top, then pour over the remaining sauce and scatter with the remaining parmesan. Cover with foil and bake for 1 hr, then remove the foil and bake for another 30 mins until golden on top.

Steps:

• 1. Preheat the oven to 200°C/400°F/gas 6.
  2. Peel and cut the potatoes into 3mm-thick slices, then cook in a large pan of boiling salted water until just tender. Drain well, then transfer to a large baking dish.
  3. Melt the butter in a large non-stick pan on a medium heat, stir in the flour, followed slowly by the milk and cream, then simmer gently until thickened, stirring continuously.
  4. Remove from the heat, grate in and stir through most of the cheese, then season to perfection with sea salt and black pepper.
  5. Pour the sauce over the potatoes, grate over the remaining cheese, then bake for 45 minutes, or until golden and bubbling.
