How to make Costco Scalloped Potatoes

Step 1:

Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish.

Step 2:

Thinly slice the potatoes and set them aside.

Step 3:

In a medium saucepan, melt the butter over medium heat, then stir in the flour and cook for about 1 minute, stirring constantly.

Step 4:

Gradually add the heavy cream and whole milk, whisking until the mixture is smooth and thickened.

Step 5:

Add the salt, black pepper, garlic powder, and nutmeg, and stir in the shredded cheddar and Gruyere cheeses until melted and the sauce is smooth.

In the prepared baking dish, layer half the sliced potatoes and pour half the cheese sauce over them.

Step 7:

Layer the remaining potatoes, then pour the remaining cheese sauce over them.

Step 8:

Sprinkle the grated Parmesan cheese evenly over the top.

Step 9:

Cover the baking dish with foil and bake for 30 minutes, then remove the foil and bake for 25-30 minutes, or until the potatoes are tender and the top is golden brown.

Step 10:

Let the scalloped potatoes cool for a few minutes before serving and garnish with chopped fresh parsley.

Tips

  • To achieve evenly thin potato slices, use a mandoline slicer. This ensures even cooking and a consistent texture.
  • Russet or Yukon Gold potatoes are ideal for scalloped potatoes. They hold their shape well and have a creamy texture when cooked.
  • After slicing, soak the potatoes in cold water for 10-15 minutes. This removes excess starch, preventing the dish from becoming too gummy.
  • Season each layer of potatoes with a pinch of salt and pepper. This ensures that every bite is flavorful.
  • Use a combination of sharp cheddar and Gruyere for a rich, complex flavor. Adding Parmesan on top creates a deliciously crispy crust.

What to pair with Costco Scalloped Potatoes

My favorite way to pair Costco Scalloped Potatoes is with a juicy, roasted chicken, as the savory flavors complement each other perfectly. Also, with some steamed green beans or asparagus, you add a fresh, crunchy contrast.

But if you like a heartier meal, adding some grilled steak or pork chops will be great. For more flavor, also consider serving with a fresh garden salad and some crusty garlic bread.
