I first made these creamy scalloped potatoes on a rainy weeknight when a simple, comforting side felt like everything we needed. Thinly sliced russets bake in a rich, spiced cream until tender and lightly golden on top. The result is a cozy, crowd-pleasing dish that works for family dinners, potlucks, or any time you want a luscious potato side. If you enjoy rich, comforting plates, you might also like Creamy Herb Chicken with Mashed Potatoes.
Why you’ll love this dish
This recipe wins for a few clear reasons. It is straightforward to assemble, uses pantry-friendly ingredients, and scales easily for guests. Russet potatoes give a silky interior and a slightly crisp edge when baked. The heavy cream and sharp cheddar create a savory, creamy sauce without needing a separate roux. Nutmeg is used sparingly to add warm depth without tasting sweet. Make this for weeknight dinners, weekend gatherings, or whenever you want a side that looks and tastes special with minimal fuss.
Step-by-step overview
You will preheat the oven, thinly slice the potatoes and onion, whisk the cream with seasonings, layer everything in a buttered 9×13 dish, cover and bake, then uncover to brown. Total hands-on time is mostly slicing; the oven does the rest. Expect about 80 minutes of baking time plus a short rest before serving.
What you’ll need
- 4 large russet potatoes, peeled and thinly sliced (about 1/8 inch thick)
- 1 medium onion, thinly sliced
- 2 cups heavy cream
- 1 cup shredded sharp cheddar cheese
- 1 teaspoon garlic powder
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon nutmeg
- 2 tablespoons unsalted butter (for greasing)
- 1/4 cup grated Parmesan cheese, optional
Notes on ingredients and substitutions
- Russets are ideal for a fluffy, creamy interior. If you prefer waxy potatoes, use Yukon Gold for a denser texture.
- For a lighter version, use whole milk mixed with 2 tablespoons melted butter per cup to approximate the fat of heavy cream.
- Sharp cheddar gives a tangy finish, but Gruyere or aged white cheddar both work well if you want a different cheese profile.
- Parmesan on top adds a salty, crisp finish but is optional.
Step-by-step instructions
- Preheat the oven to 375°F (190°C).
- Peel the potatoes and slice them into 1/8 inch rounds. Place the slices in a bowl of cold water while you work to prevent browning.
- In a medium bowl, whisk the heavy cream with the garlic powder, salt, black pepper, and nutmeg until smooth.
- Butter a 9×13-inch baking dish. Arrange half of the potato slices in an even layer across the bottom.
- Scatter half the sliced onion over the potatoes. Pour half of the cream mixture over this layer, then sprinkle half of the shredded cheddar evenly.
- Repeat with the remaining potatoes, onion, cream, and cheddar. Smooth the top with a spatula. Sprinkle the optional Parmesan over the surface if using.
- Cover the dish tightly with foil and bake for 45 minutes.
- Remove the foil and return the dish to the oven. Bake an additional 30 to 35 minutes, until the top is golden and a knife slides easily into the potatoes.
- Let the casserole rest for 10 minutes before serving so the cream settles and slicing is neater.
Best ways to enjoy it
These scalloped potatoes shine alongside roasted or grilled mains, steamed vegetables, or a simple green salad to cut the richness. For a heartier plate, serve alongside BBQ Chicken with Cheesy Garlic Potatoes. To plate, spoon generous portions into warm bowls or slice into squares and garnish with chopped parsley for color.
Storage and reheating tips
Refrigerate leftovers in an airtight container for up to 3 to 4 days. Reheat covered in a 350°F oven until warmed through, about 20 to 30 minutes for a casserole portion. For quicker reheating, microwave individual servings in 1 to 2 minute bursts, stirring or checking between intervals. To freeze, cool completely, wrap tightly with plastic and foil, and freeze up to 2 months. Thaw overnight in the refrigerator before reheating. Do not leave cooked potatoes at room temperature for more than 2 hours to avoid food safety risks.
Helpful cooking tips
- Slice evenly: Use a mandoline or a sharp knife to get uniform 1/8 inch slices so they cook at the same rate.
- Keep them cold: Soaking sliced potatoes in cold water removes surface starch and prevents discoloration. Drain and pat dry before layering.
- Check doneness: A thin knife should slide into the center with little resistance when fully cooked.
- Avoid a soupy top: If the cream seems to bubble up and brown too quickly once uncovered, tent with foil for the final minutes.
- Make ahead: Assemble the dish up to the point of baking, cover, and refrigerate for a few hours. Add a few extra minutes to the covered baking time if starting cold from the refrigerator.
Creative twists
- Herb and cheese swap: Replace some cheddar with Gruyere and add a teaspoon of fresh thyme for a slightly nutty flavor.
- Vegetable boost: Layer thin slices of parsnip or fennel with the potatoes for subtle complexity.
- Dairy-free option: Use full-fat coconut milk or a plant-based creamer and a dairy-free shredded cheese to accommodate dietary needs. Results will be slightly different in texture.
- Crispy topping: Mix panko with a little melted butter and sprinkle on top for a crunchy finish in the last 10 minutes of baking.
Helpful answers
How long does this take from start to finish?
Hands-on time is about 20 to 30 minutes, mostly slicing and assembling. Bake time is roughly 75 to 80 minutes, plus a 10-minute rest, so plan on about 1 hour and 40 minutes overall.
Can I make this ahead of time?
Yes. Assemble the dish, cover tightly, and refrigerate for up to 24 hours before baking. If chilled, add 10 to 15 minutes to the covered baking time to ensure the center reaches the proper temperature.
What if my top browns too fast?
If the surface is browning before the potatoes are done, loosely tent with foil for the remainder of baking until the potatoes are tender. Remove foil for the last few minutes if you want a crisp top.
Is it safe to freeze?
You can freeze the baked casserole for up to 2 months. Wrap tightly and thaw overnight in the refrigerator before reheating in the oven. Freezing before baking is possible, but bake from thawed for the most even texture.
Can I use a different potato type?
Yes. Yukon Gold will give you a creamier, slightly waxier result, while red potatoes will be firmer. Adjust baking time as needed since thinner, waxier potatoes may cook faster.
