Creamy Scalloped Potatoes

Ingredients Needed

Potatoes, cream and cheese. My three favourite food groups. I like using a good baking potato for this as I want them to cook soft and not be too waxy. A creamy sauce made with a simple butter and flour roux and milk flavoured with cheese (ALL the cheese) and some seasonings ensures the creamiest scalloped potatoes.

  • Potatoes. Any potatoes used for roasting will work. Yukon Gold potatoes, russet potatoes, Maris Pipier, etc.
  • Butter. I used salted butter but unsalted butter can be used too.
  • Flour. 
  • Cream. Heavy cream/Whipping cream.
  • Milk. 
  • Grated cheese. Cheddar/Gruyere/Jack cheese/Colby/Raclette/Havarti are all good cheeses to use for this recipe.
  • Seasoning: Nutmeg, cayenne pepper, salt and black pepper. Other spices like garlic powder and onion powder or herbs like thyme, rosemary, sage and oregano will all be delicious too.
  • Parmesan cheese.

How to make scalloped potatoes

  1. Make the cream sauce: Melt the butter in a saucepan set over medium heat. Whisk in the flour then cook for a minute or two until lightly golden. Slowly whisk in the cream and milk until the sauce is smooth. Add the nutmeg, cayenne, salt and pepper then reduce the heat and cook, stirring regularly, until the sauce is silky and thick. Remove from the heat and stir in the grated cheese.
  2. Assemble: Peel and thinly slice potatoes (½cm/¼inch thick) with a sharp knife or a mandolin. Place a layer of potatoes into an oven-proof baking dish/casserole dish then season with salt and pepper. Pour over some of the cheese sauce. Repeat until all the potatoes and sauce has been used, covering the last layer of the potatoes with the remaining sauce.
  3. Bake: Cover the baking dish tightly with foil then place in the oven and allow to bake for 45-60 minutes or until the potatoes are tender. Test by inserting a knife, it it goes in easily, the potatoes are cooked. Remove from the oven, scatter over the grated Parmesan and place under the broiler for 5-7 minutes or until golden brown. Remove from the oven, allow to cool for 10 minutes then serve.

Can you make scalloped potatoes ahead of time?

Yes, absolutely. The potatoes can be prepped and assembled up to 2 days in advanced. Cover well and keep in the fridge until ready to bake. Leftover potatoes can be kept covered in the fridge for up to 3 days and reheated in the microwave oven or oven.

Serving suggestions

This scalloped potato recipe is the perfect side dish for any protein. It’s especially delicious with roasted leg of lamb, lemon roasted chicken or salt and pepper pork belly. We also love it during the holidays with roast turkey or glazed ham.
