Easy Scalloped Potatoes: A Creamy, Comforting Side Dish Made Step by Step

Easy scalloped potatoes are one of those classic comfort foods that feel warm, rich, and satisfying with every bite. This dish is made with thinly sliced potatoes baked in a creamy sauce until soft, golden, and tender. It is simple enough for a family dinner but special enough to serve during holidays, parties, or weekend meals.

The best part about scalloped potatoes is that they use basic ingredients, yet the final result tastes homemade and impressive. With the right slicing, layering, and baking method, you can create a creamy potato dish that is full of flavor and has a beautiful golden top.

What Are Scalloped Potatoes?

Scalloped potatoes are thin slices of potatoes baked in a creamy milk or cream-based sauce. Traditionally, they do not always include cheese, but many modern versions add cheese for extra richness. The potatoes absorb the sauce as they bake, becoming soft and flavorful while the top turns lightly crisp and golden.

This recipe is called “easy” because it avoids complicated steps. You do not need advanced cooking skills. You only need to prepare the sauce, slice the potatoes, layer everything in a baking dish, and let the oven do the rest.

Ingredients You Will Need

To make easy scalloped potatoes, you will need:

4 to 5 medium potatoes
2 tablespoons butter
2 tablespoons all-purpose flour
2 cups milk
1 cup shredded cheddar cheese
1 small onion, finely chopped
2 cloves garlic, minced
½ teaspoon salt
½ teaspoon black pepper
½ teaspoon paprika
¼ teaspoon dried thyme or mixed herbs
Extra cheese for topping
Fresh parsley for garnish

Yukon Gold or Russet potatoes work well for this recipe. Yukon Gold potatoes give a creamy texture, while Russet potatoes become soft and fluffy after baking.

Step 1: Prepare the Potatoes

Start by washing and peeling the potatoes. You can leave the skin on if you prefer a more rustic texture, but peeled potatoes give a smoother and more classic result.

Slice the potatoes thinly and evenly. The slices should be about ⅛ inch thick. Thin slices cook faster and absorb the creamy sauce better. If the slices are too thick, the potatoes may take longer to become tender.

After slicing, place the potatoes in a bowl of cold water for a few minutes. This helps remove extra starch and prevents the slices from turning brown. Before using them, drain the water and pat the potato slices dry with a clean towel.

Step 2: Make the Creamy Sauce

In a medium saucepan, melt the butter over medium heat. Add the chopped onion and cook for 2 to 3 minutes until it becomes soft and fragrant. Then add the minced garlic and cook for another 30 seconds.

Next, add the flour and stir continuously. This creates a simple roux, which helps thicken the sauce. Cook the flour and butter mixture for about one minute, but do not let it turn brown.

Slowly pour in the milk while whisking. Keep stirring to avoid lumps. As the milk heats, the sauce will begin to thicken. Add salt, black pepper, paprika, and dried thyme. Stir well so the seasoning spreads evenly through the sauce.

Once the sauce becomes slightly thick and smooth, add the shredded cheddar cheese. Stir until the cheese melts completely. Remove the sauce from the heat.
