Creamy Pour-Over Potatoes

Creamy Pour-Over Potatoes

Serves: 6–8
Prep: 25 minutes
Bake: 55–70 minutes
Total: about 1½ hours

Ingredients

For the potatoes

• 1.5 kg potatoes, preferably Yukon Gold or another waxy-to-all-purpose variety

• 2 tablespoons butter, plus extra for the casserole dish

• 1 teaspoon salt

• ½ teaspoon freshly ground black pepper

• ½ teaspoon garlic powder, optional

• ½ teaspoon dried thyme

• ½ cup grated Parmesan, optional

• ½ cup shredded mozzarella or Gruyère, optional

For the creamy pour-over

• 3 tablespoons butter

• 3 tablespoons all-purpose flour

• 2 cups whole milk

• 1 cup heavy cream

• 3 cloves garlic, finely minced

• 1 teaspoon salt

• ½ teaspoon black pepper

• ½ teaspoon dried thyme

• ¼ teaspoon nutmeg

• ½ cup finely grated Parmesan

• 1 teaspoon Dijon mustard, optional

Instructions

1. Heat the oven.
   Set your oven to 190°C / 375°F. Generously butter a 9 × 13-inch glass casserole dish.

2. Prepare the potatoes.
   Peel the potatoes if you like, or leave the skins on for a more rustic casserole. Slice them very thinly—about 3 mm (⅛ inch) thick. A mandoline makes this particularly easy, but a sharp knife works too.

   Try to keep the slices relatively uniform so they cook at the same rate.

3. Make the creamy sauce.
   Melt 3 tablespoons of butter in a saucepan over medium heat. Add the minced garlic and cook for about 30 seconds, just until fragrant.

   Sprinkle in the flour and whisk constantly for about 1 minute. You want a smooth, pale roux rather than browned flour.

4. Add the dairy.
   Slowly pour in the milk while whisking continuously to prevent lumps. Add the heavy cream and continue whisking.

   Stir in the salt, pepper, thyme, and nutmeg. Cook for 3–5 minutes, stirring frequently, until the mixture thickens enough to lightly coat the back of a spoon.

5. Make it extra savory.
   Remove the saucepan from the heat. Stir in the Parmesan and Dijon mustard, if using. Taste the sauce and adjust the salt and pepper.

   The sauce should taste slightly more seasoned than you think it needs to be—the potatoes will absorb a lot of that flavor.

6. Layer the potatoes.
   Arrange about one-third of the potato slices across the bottom of the buttered casserole dish. Don’t worry about making them perfectly neat.

   Sprinkle lightly with salt, pepper, and thyme. Add another layer of potatoes and repeat until all the potatoes are in the dish.

7. Pour over the cream sauce.
   Slowly pour the warm creamy sauce over the potatoes, making sure it reaches down between the layers. Gently press the potatoes down with the back of a spoon or spatula so the sauce can work its way throughout the casserole.

   If using Parmesan and mozzarella/Gruyère, sprinkle them over the top.

8. Cover and bake.
   Cover the casserole tightly with aluminum foil and bake for 40 minutes.

   Covering it at first traps steam, helping the potatoes become tender instead of leaving you with a beautifully browned top and crunchy potatoes underneath.

9. Uncover and finish.
   Remove the foil and continue baking for another 20–30 minutes, until the top is bubbling, golden brown, and the potatoes can be pierced easily with a knife.

   If you want an especially dramatic golden crust, switch on the broiler for the final 1–2 minutes, watching it closely.

10. Rest before serving.
    This part is important: let the casserole rest for 10–15 minutes before serving.

    The sauce will thicken slightly as it settles, and the layers will hold together better when you scoop them out.

Make it ridiculously cozy

For an even richer supper, add one or two of these between the potato layers:

• Caramelized onions for sweetness and depth

• Crispy bacon or smoked turkey for a smoky, salty element

• Sautéed mushrooms for an earthy flavor

• Cooked spinach for some greenery

• Shredded Gruyère for an especially luxurious cheese crust

• Fresh rosemary or thyme for a wintery aroma

The little trick that makes it great

Don’t rinse the sliced potatoes after cutting them. Their surface starch helps the cream sauce become thick and velvety as everything bakes together.

And don’t be tempted to pour the sauce only over the top. Get it down between the potato layers—that’s what turns ordinary baked potatoes into that soft, creamy, almost spoonable casserole.

Serve it piping warm alongside roasted vegetables, a crisp green salad, or simply some crusty bread for mopping up every last bit of sauce.
