Cheesy Scalloped Potatoes: A Creamy, Comforting Classic

Few dishes capture the essence of comfort food quite like cheesy scalloped potatoes. With tender slices of potato layered in a rich, creamy sauce and finished with a golden, bubbling cheese crust, this dish is a staple for family dinners, holidays, and cozy evenings. Despite its elegant appearance, it’s surprisingly simple to prepare with just a few basic ingredients and some patience.

What Are Scalloped Potatoes?

Scalloped potatoes are thinly sliced potatoes baked in a creamy sauce, often made with milk, butter, and flour. When cheese is added, the dish becomes even more indulgent—sometimes referred to as “au gratin,” though traditional scalloped potatoes don’t always include cheese. This version leans into that cheesy goodness for maximum flavor.

Ingredients

To make cheesy scalloped potatoes, you’ll need:

4–5 medium potatoes (Yukon Gold or Russet work best)
2 tablespoons butter
2 tablespoons all-purpose flour
2 cups milk (whole milk preferred for creaminess)
1 cup shredded cheese (cheddar is classic, but feel free to mix)
1/2 cup additional cheese for topping
2 cloves garlic (minced)
Salt and pepper to taste
Optional: a pinch of nutmeg or paprika for extra flavor

Step-by-Step Method

Step 1: Prepare the Potatoes

Start by peeling the potatoes (optional, depending on preference) and slicing them into thin, even rounds—about 2–3 mm thick. Uniform slices are important to ensure even cooking.

Place the slices in cold water to prevent browning while you prepare the sauce.

Step 2: Make the Creamy Sauce

In a medium saucepan over medium heat, melt the butter. Add the minced garlic and cook for about 30 seconds until fragrant.

Stir in the flour and whisk continuously for 1–2 minutes to form a smooth roux. This step helps thicken the sauce.

Gradually pour in the milk while whisking to avoid lumps. Continue cooking and stirring until the mixture thickens into a creamy consistency—this should take about 5 minutes.

Add salt, pepper, and optional spices. Then stir in the shredded cheese until fully melted and smooth.
