Cheesy Scalloped Potatoes Recipe

A Classic Comfort Food Side Dish

Cheesy scalloped potatoes are a warm, creamy, and satisfying side dish that can make almost any meal feel more special.

Made with thin layers of tender potatoes and a rich cheese sauce, this baked dish delivers comfort in every serving.

It is hearty enough for a holiday table, yet simple enough to serve with a relaxed family dinner.

Why This Dish Always Stands Out

The appeal of cheesy scalloped potatoes comes from the combination of soft potatoes, smooth sauce, and a golden baked topping.

As the casserole bakes, the potatoes absorb the creamy sauce while the cheese on top melts into a bubbly crust.

The result is a rich side dish that often becomes one of the most memorable parts of the meal.

Scalloped Potatoes and Au Gratin Potatoes

Scalloped potatoes are traditionally made with potatoes baked in a cream-based sauce.

Potatoes au gratin usually include grated cheese and sometimes breadcrumbs.

This version brings both ideas together by using the layered style of scalloped potatoes with the cheesy richness often found in au gratin dishes.

Best Potatoes to Use

Yukon Gold potatoes are an excellent choice because they have a buttery flavor and hold their shape well while baking.

Russet potatoes also work well and can help naturally thicken the sauce because of their higher starch content.

For the smoothest texture, the potatoes should be peeled before slicing.

The Secret to a Smooth Cheese Sauce

A creamy sauce begins with a proper roux made from butter and flour.

Onion and garlic are first cooked in butter to create a savory flavor base.

Flour is then added and cooked briefly to remove the raw taste before the milk is slowly whisked in.

Adding the milk gradually while whisking helps create a smooth sauce without lumps.

Ingredients You Need

This recipe uses two pounds of peeled Yukon Gold or Russet potatoes sliced very thin.

Unsalted butter gives better control over the salt level, while diced onion and minced garlic add depth.

All-purpose flour thickens the sauce, and whole milk creates the creamy base.

Sharp cheddar cheese gives the dish a bold flavor, while mozzarella or Gruyère adds extra richness and meltiness.

Salt, black pepper, and a small amount of paprika complete the seasoning.

Preparing the Potato Slices

Even potato slices are important because they help the dish cook properly.

The slices should be about one-eighth of an inch thick.

A mandoline slicer is useful for keeping every slice the same size, but a sharp knife can also work carefully.

How to Assemble the Dish

Start by lightly greasing a 9×13 inch baking dish with butter or non-stick spray.

Place half of the sliced potatoes in an even, slightly overlapping layer across the bottom.

Pour half of the prepared cheese sauce over the potatoes.

Add the remaining potatoes in a second layer, then cover them with the rest of the sauce.

Finish by sprinkling the remaining shredded cheese evenly over the top.

Baking Until Golden and Tender

The dish should first be covered tightly with foil and baked at 375°F for 40 minutes.

This covered stage traps steam and helps the potatoes become tender without drying out.

After 40 minutes, remove the foil and continue baking for another 15 to 25 minutes.

The casserole is ready when the top is golden and bubbly and a fork easily slides through the center layers.

Make-Ahead and Storage Tips

Cheesy scalloped potatoes can be assembled ahead of time and kept covered in the refrigerator for up to 24 hours before baking.

Before placing the dish in the oven, let it sit at room temperature for about 30 minutes.

If baking from chilled, the covered baking time may need about 10 extra minutes.

Leftovers can be stored in an airtight container in the refrigerator for up to 4 days.

Individual portions can be reheated in the microwave, or the full dish can be warmed in the oven at 350°F.

What to Serve with Cheesy Scalloped Potatoes

This rich potato dish pairs well with holiday ham, roasted turkey, pot roast, or baked chicken.

Because the casserole is creamy and filling, it also works well with lighter vegetables on the side.

Roasted asparagus, garlic green beans, or a crisp garden salad can help balance the richness of the cheese sauce.

Served hot from the oven, cheesy scalloped potatoes remain a dependable comfort food favorite for family dinners, holidays, and cozy gatherings.
