Classic Creamy Scalloped Potatoes Recipe for Comforting Dinners

Scalloped potatoes are a rich, comforting side that complements a wide range of meals. Thinly sliced potatoes baked in a creamy homemade béchamel yield a golden, bubbling dish with tender, melt-in-your-mouth layers—perfect for family dinners or special occasions.

This recipe uses simple ingredients and straightforward steps to create a classic, crowd-pleasing side dish. The béchamel sauce is seasoned gently so the potato flavor shines, and an optional cheese addition makes the casserole even more indulgent.

Ingredients

For the Potatoes:

• 4 large russet or Yukon Gold potatoes, thinly sliced (about 1/8-inch thick)
• 1 tablespoon unsalted butter (for greasing the dish)
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/2 teaspoon paprika (optional, for color and mild flavor)

For the Béchamel Sauce:

• 3 tablespoons unsalted butter
• 3 tablespoons all-purpose flour
• 2 cups whole milk, warmed
• 1 cup heavy cream
• 1/2 teaspoon salt
• 1/4 teaspoon ground nutmeg
• 1/2 teaspoon garlic powder
• 1 cup shredded cheese (cheddar, Gruyère, or Parmesan — optional for a richer flavor)

Instructions

1. Prepare the Potatoes

Wash and peel the potatoes. Using a mandoline or a sharp knife, slice them into even 1/8-inch rounds so they cook uniformly. Place the slices in a large bowl of cold water to prevent discoloration, then drain and pat dry before assembling.

2. Preheat the Oven and Grease the Dish

Preheat the oven to 375°F (190°C). Butter a 9×13-inch baking dish to prevent sticking and help the edges crisp up slightly.

3. Make the Béchamel Sauce

In a medium saucepan over medium heat, melt 3 tablespoons of butter. Whisk in the flour and cook for about 1 minute to form a smooth roux. Gradually add the warmed milk and heavy cream while whisking constantly to avoid lumps.

Season the sauce with salt, nutmeg, and garlic powder. Cook until the sauce thickens, about 3–5 minutes. If you choose to add cheese, stir it in now until fully melted and smooth.

4. Assemble the Layers

Place one-third of the potato slices in an even layer in the greased baking dish. Season with a bit of salt, pepper, and a light dusting of paprika if desired. Spoon some of the béchamel over the potatoes and spread it evenly. Repeat with two more layers, finishing with sauce covering the top.

For a decorative presentation, you can stand the slices upright in a circular or fanned pattern; this encourages crispier edges while keeping the center creamy. Brushing the top with melted butter before baking promotes a deep golden finish.

5. Bake to Perfection

Cover the dish with aluminum foil and bake for 45 minutes. Remove the foil and bake another 20–25 minutes until the top is golden brown and bubbling. Test doneness by inserting a fork or knife; it should pass through the potatoes easily.

6. Rest and Serve

Let the scalloped potatoes rest for about 10 minutes before serving. Resting allows the sauce to set slightly, making it easier to slice and enhancing the overall texture. Garnish with chopped parsley or chives if you like.

Recipe Notes

Potato choice affects texture: russets create a softer, creamier result, while Yukon Golds hold their shape better and offer a naturally buttery flavor. Aim for consistent, thin slices for even cooking—using a mandoline speeds up this step and improves uniformity. Traditionally scalloped potatoes are made without cheese, but adding a cup of shredded cheese yields a richer, creamier dish.

Make-Ahead Tip – Assemble the dish a day ahead, cover, and refrigerate. Add 10–15 minutes to the baking time if baking straight from the fridge.

Storage – Store leftovers in an airtight container in the refrigerator for up to four days. Reheat in a 350°F oven for best texture rather than using the microwave.

Freezing – You can freeze scalloped potatoes, though the texture may change slightly. Cool completely, cover tightly, and freeze for up to two months. Thaw in the refrigerator before reheating for best results.
