I still remember the first time I layered thin potato slices with a rich cream spiked with nutmeg and garlic powder; the kitchen filled with a warm, comforting aroma and every forkful felt like a cozy hug. This recipe for creamy scalloped potatoes turns simple pantry staples into a silky, cheesy casserole that’s perfect for family dinners or when you want to bring a crowd-pleasing side to a weeknight meal. For another take on this classic that leans even more into melty cheese, see the Creamy Scalloped Potatoes recipe page for inspiration.

Why you’ll love this dish

This is comfort food that is easy to make and stretches well. It uses inexpensive russet potatoes and pantry seasonings to create a richly textured side. The heavy cream gives a velvety sauce while a touch of nutmeg adds warmth that you might not expect but will notice when people ask what makes it taste so cozy. It is ideal for a relaxed Sunday supper, a simple weeknight upgrade, or anytime you want a reliable, shareable dish that travels well to potlucks.

Step-by-step overview

You will prepare the potatoes, whisk the cream with the seasonings, layer potatoes and onions with cheese, then bake covered and finish uncovered to brown the top. Total bake time is about 75 to 80 minutes. Expect roughly 15 to 20 minutes extra for peeling, slicing, and assembling.

What you’ll need

• 4 large russet potatoes, peeled and thinly sliced, about 2 pounds (slice to roughly 1/8 inch)
• 1 medium onion, thinly sliced
• 2 cups heavy cream, the base of the sauce (substitute: 1 cup whole milk plus 1 cup half and half for a lighter texture)
• 1 cup shredded sharp cheddar cheese (or a mix of cheddar and Gruyere for nuttiness)
• 1 teaspoon garlic powder
• 1 teaspoon salt, adjust to taste
• 1/2 teaspoon black pepper
• 1/4 teaspoon nutmeg, a small pinch goes a long way
• 2 tablespoons unsalted butter, for greasing the dish
• 1/4 cup grated Parmesan cheese, optional for a crispier, savory top

Notes: If you need a lower-fat option, use lower-fat dairy but expect a thinner sauce. A mandoline helps get even slices, which produces consistent cooking.

Step-by-step instructions

Preheat the oven to 375°F (190°C).

Peel the potatoes and slice them about 1/8 inch thick. Use a sharp knife or a mandoline for even slices. Place the slices in a large bowl of cold water to draw out excess starch. This keeps the sauce from becoming gluey.

Whisk the heavy cream with garlic powder, salt, pepper, and nutmeg in a large mixing bowl until smooth.

Grease a 9×13-inch baking dish with the butter. Arrange half of the potato slices in an even layer in the dish. Scatter half of the sliced onion over the potatoes. Spoon half of the cream mixture over the layers. Sprinkle half of the cheddar cheese on top.

Repeat the layers with the remaining potatoes, onions, cream, and cheddar. Smooth the top so the cream can seep between slices. If using, sprinkle the Parmesan on the surface.

Cover the baking dish tightly with aluminum foil and bake for 45 minutes. Carefully remove the foil and bake an additional 30 to 35 minutes until the top turns golden brown and a skewer slides through a slice with no resistance.

Remove from the oven and let the casserole rest for 10 minutes before serving. This rest lets the sauce set so you get neat slices.

Best ways to enjoy it

Serve warm, cut into squares or spooned onto plates. Pair it with a simple green salad dressed with lemon and olive oil, roasted seasonal vegetables, or a roasted chicken breast for a complete meal. For a cheesier take or a slightly different flavor profile, check this cheesy scalloped potatoes variation that swaps cheeses and toppings.

Garnish ideas: chopped chives, a sprinkle of extra Parmesan, or a few thyme leaves. For neat portions, use a wide spatula and press slightly when lifting so the layers hold together.

Storage and reheating tips

Cool the casserole to room temperature within two hours of baking. Store in an airtight container or cover the dish with foil and refrigerate for up to 3 to 4 days. Reheat in a 350°F oven until warmed through, about 20 to 30 minutes, which helps revive the sauce and crisp the top slightly. For quicker reheating, individual servings microwave well for 1 to 2 minutes, stirring midway if needed. To freeze, cool completely, wrap tightly in plastic wrap and foil, and freeze up to 2 months. Thaw overnight in the refrigerator before reheating.

Food safety note: reheat until the interior reaches at least 165°F for safe consumption.

Helpful cooking tips

• Slice potatoes uniformly. Even thickness equals even cooking. A mandoline saves time and ensures consistent results.
• After soaking, pat potato slices dry with kitchen towels. Excess water thins the sauce and prolongs baking.
• Do not skimp on resting time. The 10-minute rest firms the layers so servings hold their shape.
• Taste the cream mixture before assembling. The potatoes dilute seasoning, so a slightly bold seasoning in the cream is better.
• If your oven runs cool, cover for longer during the first bake to prevent drying, then uncover to brown.

Recipe variations

• Add mushrooms and thyme for an earthy version. Sauté mushrooms first to remove moisture.
• Swap half the cheddar for Gruyere or fontina for a nuttier, more complex flavor.
• Make individual portions in ramekins for elegant single servings and shorter bake times.
• For a crunchy top, mix panko with a tablespoon of melted butter and sprinkle over the dish in the last 10 minutes of baking.

Common questions

How thin should I slice the potatoes

Aim for about 1/8 inch thick. Thinner slices cook faster and meld with the sauce; thicker slices need more baking time and may end up slightly firmer.

Can I use Yukon Gold or red potatoes instead of russets

Yes. Yukon Gold will give a creamier, naturally buttery texture. Red potatoes hold their shape more and give a firmer bite. Adjust bake time if slices are thicker.

How do I know when the casserole is done

A clean skewer or knife should slide through the center potato slice easily. The top should be golden brown after you remove the foil and finish the bake. If the interior still resists, cover and bake another 10 to 15 minutes.

Can I make this ahead of time

Yes. Assemble the casserole, cover tightly, and refrigerate overnight. Add about 10 to 15 minutes to the total bake time if refrigerating before baking, since the dish will start colder.

Is it safe to freeze

Yes. Freeze cooled, well wrapped portions for up to 2 months. Thaw in the refrigerator before reheating in the oven for best texture.
