Ingredients

Scale

Potatoes

  • 6 medium potatoes

Sauce

  • 1 cup full-fat milk (250 ml)
  • 1 cup double cream / heavy cream (250 ml)
  • 1 tbsp plain flour
  • 30 g butter (2 tbsp)
  • 1 cup Cheddar cheese (100 g)
  • 2 tbsp grated parmesan
  • 1 tbsp Dijon mustard
  • A pinch of nutmeg
  • Salt and pepper to taste
  • 2 cloves garlic, peeled and minced

Instructions

  1. Preheat Oven: Preheat your oven to 200°C (390°F) to prepare for baking the scalloped potatoes.
  2. Prepare Potatoes: Peel the potatoes thoroughly and wash them well to remove any dirt or impurities.
  3. Make Roux: In a saucepan over medium heat, melt the butter. Once melted, add the plain flour and stir quickly to form a roux that will thicken the sauce.
  4. Add Milk: Gradually whisk in the full-fat milk, mixing continuously to prevent lumps from forming in the sauce.
  5. Thicken Sauce & Add Cheese: Continue stirring the sauce until it slightly thickens. Then add the cheddar cheese, grated parmesan, and double cream to create a rich, cheesy sauce.
  6. Incorporate Garlic: Add the minced garlic cloves to the sauce to infuse it with savory flavor.
  7. Add Mustard & Seasoning: Mix in the Dijon mustard and season with nutmeg, salt, and pepper to taste for added depth.
  8. Slice Potatoes: Thinly slice the peeled potatoes to ensure even cooking in the layers.
  9. Layer Potatoes and Sauce: Grease a non-stick baking dish with butter. Arrange one layer of potato slices in the dish with slight overlapping.
  10. First Sauce Layer: Pour a quarter of the cheese sauce evenly over the potato layer.
  11. Repeat Layers: Add another layer of potatoes followed by more sauce. Repeat until all potatoes and sauce are used, finishing with a sauce layer on top.
  12. Bake Covered: Cover the baking dish with foil and place it in the oven. Bake at 200°C (390°F) for 1 hour, allowing the potatoes to cook through and flavors to meld.
  13. Brown the Top: Remove the foil, increase the oven temperature to 220°C (410°F), and bake uncovered for an additional 15 minutes to achieve a golden, crispy top layer.
  14. Serve: Remove from oven and serve the cheesy scalloped potatoes hot as a delicious side or main dish.

Notes

  • Ensure potatoes are sliced thinly and evenly for uniform cooking.
  • Use full-fat milk and cream for a richer sauce; low-fat substitutes will change the texture.
  • Don’t skip the resting time in the oven with foil as it allows the potatoes to become tender.
  • For a crustier top, you can add extra parmesan or breadcrumbs before the final bake.
  • This dish pairs well with roasted meats or a fresh green salad.
