Ingredients You’ll Need
The beauty of this cheesy scalloped potatoes recipe lies in its simple, high-quality ingredients that work together to create something extraordinary. Russet potatoes are my top choice because they hold their shape beautifully while becoming perfectly tender, and their starch content helps thicken the sauce naturally as it bakes.
The creamy sauce is built on a foundation of butter, flour, and heavy cream, with sharp cheddar cheese adding that irresistible tangy richness. Fresh thyme brings an earthy note that complements the potatoes beautifully, while a touch of nutmeg adds warmth and depth that takes this dish from good to absolutely spectacular.

- 4 tablespoons all-purpose flour
- 2 cups heavy cream (room temperature)
- 1 cup whole milk (room temperature)
- 1 teaspoon salt
- 1/2 teaspoon black pepper (freshly ground)

- 2 sprigs fresh thyme (leaves removed)

How to Make Classic Scalloped Potatoes Recipe (Step-by-Step)
1. Prepare the Potatoes and Dish
Preheat your oven to 375°F (190°C). Generously butter a 9×13-inch baking dish and set aside.
Peel the potatoes and slice them into 1/8-inch thick rounds using a mandoline slicer or sharp knife. Keep slices in cool water to prevent browning while you work.
Pro tip: Consistent thickness is key – thinner slices cook more evenly and create better layers.
2. Make the Cream Sauce
In a large saucepan, melt 4 tablespoons of butter over medium heat. Whisk in the flour and cook for 2 minutes, stirring constantly to create a light roux.
Pro tip: Don’t let the roux brown – you want it pale and smooth for the best color in your finished dish.
Gradually whisk in the heavy cream and milk, adding about 1/2 cup at a time to prevent lumps. Continue whisking until the sauce is smooth and begins to thicken, about 5-7 minutes.
Pro tip: Room temperature dairy prevents the sauce from breaking and creates a silkier texture.
Season with salt, pepper, nutmeg, and fresh thyme leaves. Remove from heat and stir in 1 cup of the cheddar cheese until melted and smooth.
3. Layer the Potatoes
Drain the potato slices and pat them dry with paper towels. Arrange half of the potato slices in overlapping layers in the prepared baking dish.
Pro tip: Slightly overlapping slices create beautiful presentation and help the dish hold together when served.
Pour half of the cream sauce over the first layer of potatoes, making sure to get sauce between the slices. Add the remaining potatoes in another overlapping layer.
Pro tip: Use a spoon to gently lift edges and let sauce flow underneath for even coverage.
4. Add Final Touches and Bake
Pour the remaining cream sauce over the top layer of potatoes. Sprinkle with the remaining cheddar cheese and all of the Gruyère cheese.
Pro tip: Don’t skip the Gruyère – it adds incredible nutty flavor and helps create that perfect golden top.
Cover tightly with foil and bake for 45 minutes. Remove foil and continue baking for 25-30 minutes until the top is golden brown and the potatoes are fork-tender.
Pro tip: Test doneness by inserting a knife through all layers – it should slide in easily with no resistance.
Let rest for 10-15 minutes before serving to allow the sauce to set up properly.
Pro tip: This resting time is crucial – it prevents the dish from being too liquidy when you serve it.

Notes
- For best results, slice potatoes uniformly using a mandoline slicer
- Let dish rest 10-15 minutes after baking for proper sauce consistency

Tips for the Best Classic Scalloped Potatoes Recipe
- Slice Consistency is Everything: Use a mandoline slicer or take your time with a sharp knife to ensure all potato slices are the same thickness for even cooking.
- Don’t Skip the Resting Time: Let the dish rest for 10-15 minutes after baking – this allows the sauce to thicken and makes serving much easier.
- Room Temperature Dairy: Take your cream and milk out of the fridge 30 minutes before cooking to prevent the sauce from breaking when you add it to the roux.
- Grate Your Own Cheese: Pre-shredded cheese has anti-caking agents that prevent smooth melting – freshly grated cheese creates a much creamier result.
- Test for Doneness: Insert a thin knife through all the layers – it should slide through easily when the potatoes are perfectly tender.
- Make-Ahead Magic: Assemble the entire dish up to 24 hours ahead, cover, and refrigerate. Add 15-20 minutes to the covered baking time if starting from cold.
Variations to Try
- Bacon Lover’s Version: Add 6 strips of cooked, crumbled bacon between the potato layers for smoky richness that pairs perfectly with the creamy sauce.
- Herb Garden Delight: Mix in fresh rosemary, sage, and parsley with the thyme for a more complex herbal flavor profile that’s perfect for special occasions.
- Three-Cheese Indulgence: Replace some cheddar with Parmesan and fontina for an even more decadent, restaurant-style easy potato gratin experience.
- Garlic and Onion Version: Sauté thinly sliced onions and minced garlic, then layer them with the potatoes for extra depth and aroma.
- Lighter Version: Substitute half the heavy cream with chicken or vegetable broth and use a mixture of sharp cheddar and reduced-fat cheese.

Frequently Asked Questions
Can I make scalloped potatoes ahead of time?
Yes! You can assemble the entire dish up to 24 hours before baking. Cover tightly with plastic wrap and refrigerate. When ready to bake, remove plastic wrap, cover with foil, and add 15-20 minutes to the initial covered baking time since you’re starting with a cold dish.
Why are my scalloped potatoes watery or soupy?
Watery scalloped potatoes usually result from not letting the dish rest after baking or using potatoes with too much moisture. Always let the dish rest 10-15 minutes before serving, and make sure to pat potato slices dry before layering. Also, avoid using waxy potatoes like red potatoes, which release more moisture.
What’s the difference between scalloped potatoes and au gratin potatoes?
The main difference is that traditional scalloped potatoes are made with a white cream sauce and may or may not include cheese, while au gratin potatoes always include cheese and often have a more golden, cheese-crusted top. However, many modern recipes (like this one) blur the lines by including both cream sauce and cheese.
How do I prevent my scalloped potatoes from curdling?
To prevent curdling, make sure your dairy ingredients are at room temperature before adding them to the roux, add them gradually while whisking constantly, and don’t let the sauce boil vigorously. If your sauce does start to curdle, remove it from heat immediately and whisk in a tablespoon of cold cream.
Can I use different types of potatoes for scalloped potatoes?
Russet potatoes are ideal because they have the right balance of starch and hold their shape well. You can use Yukon Gold potatoes for a creamier texture, but avoid red potatoes or other waxy varieties as they can become mushy and release too much moisture during baking.
