This recipe focuses on simple, high-quality ingredients and a straightforward technique that guarantees success. We will build a luxurious sauce from scratch, ensuring it clings to every slice of potato. Therefore, you can say goodbye to bland, soupy potatoes forever. In addition, we’ll share essential tips for getting those beautiful, distinct layers and that irresistible crispy top. Get ready to master a classic dish that will have everyone asking for seconds.
The Secret to Perfectly Creamy Scalloped Potatoes
The magic behind truly exceptional creamy scalloped potatoes lies in three key areas: the type of potato you choose, the construction of the sauce, and the precision of your slicing. Mastering these elements is crucial for the final result. Consequently, paying attention to these details will elevate your dish from good to unforgettable. Let’s break down why each of these components is so important.
Choosing the Right Potatoes
First and foremost, the potato itself is the star of the show. For this dish, you want a potato with a good amount of starch. Starchy potatoes, like Russets or Yukon Golds, are ideal because their starch helps thicken the sauce as the dish bakes. According to the Harvard T.H. Chan School of Public Health, different potato varieties have varying starch levels, which impacts their best culinary use. As a result, this creates a naturally creamier consistency. Russet potatoes tend to break down a bit more, leading to a very tender, melt-in-your-mouth texture. On the other hand, Yukon Golds hold their shape slightly better while still offering a buttery flavor and creamy bite. You should generally avoid waxy potatoes like red potatoes, as they don’t release enough starch and can lead to a thinner, less cohesive sauce.
Crafting the Perfect Cream Sauce
Next, the sauce is what transforms sliced potatoes into a decadent masterpiece. A common mistake is to simply pour cream over the potatoes, which can sometimes curdle or fail to thicken properly. Therefore, the best approach is to create a simple béchamel sauce. This classic white sauce starts with a roux, which is a mixture of melted butter and flour. This roux is the foundation that thickens the milk and cream, creating a stable, velvety sauce that will never be watery. Proper handling of dairy is also key; the FDA provides important safety tips for milk, cream, and cheese. Furthermore, infusing the sauce with garlic, onion powder, and a hint of nutmeg adds layers of savory depth that complement the potatoes beautifully.
The Art of Slicing
Finally, consistency is key. For your creamy scalloped potatoes to cook evenly, each potato slice must be the same thickness. If some slices are thick and others are paper-thin, you will end up with a mix of mushy and undercooked potatoes. The ideal thickness is about 1/8-inch. While you can certainly achieve this with a sharp knife and a steady hand, a mandoline slicer is the most effective tool for this job. It ensures every single slice is perfectly uniform, which in turn guarantees that every bite of your final dish is cooked to tender perfection.

Ingredients You’ll Need For Creamy Scalloped Potatoes
This recipe relies on simple, classic ingredients to build its rich flavor. Here is what you will need to gather before you start cooking.
- 2.5 lbs Russet or Yukon Gold potatoes, peeled and thinly sliced
- 4 tablespoons unsalted butter
- 1 small yellow onion, finely minced
- 2 cloves garlic, minced
- 1/4 cup all-purpose flour
- 2 cups whole milk, warmed
- 1 cup heavy cream, at room temperature
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon ground nutmeg
- 1.5 cups shredded sharp cheddar or Gruyère cheese (optional, but recommended)
Step-by-Step Instructions: Creamy Scalloped Potatoes
Follow these steps carefully to assemble and bake your delicious creamy scalloped potatoes. The process is straightforward and rewarding, leading to a perfect result every time.
- Preheat and Prepare: First, preheat your oven to 400°F (200°C). Then, generously butter a 9×13-inch baking dish.
- Slice Potatoes: Peel your potatoes and slice them into 1/8-inch thick rounds. A mandoline is highly recommended for uniform slices. Place the sliced potatoes in a bowl of cold water to prevent them from browning while you prepare the sauce.
- Sauté Aromatics: In a medium saucepan, melt the butter over medium heat. Next, add the minced onion and cook until softened, which usually takes about 3-4 minutes. Add the minced garlic and cook for another minute until it is fragrant.
- Make the Roux: Sprinkle the flour over the onions and garlic. Whisk constantly for about one minute to cook out the raw flour taste. This forms the roux that will thicken your sauce.
- Build the Cream Sauce: Gradually whisk in the warm milk, a little at a time, to prevent lumps. Once all the milk is incorporated, whisk in the heavy cream. Continue to cook, stirring frequently, until the sauce begins to thicken, which should take about 5-7 minutes.
- Season and Finish Sauce: Remove the saucepan from the heat. Stir in the salt, pepper, and ground nutmeg. If you are using cheese, stir in 1 cup now, saving the rest for the top.
- Layer the Dish: Drain the potatoes and pat them dry. Arrange one-third of the potato slices in an even, overlapping layer in the bottom of your prepared baking dish. Pour about one-third of the creamy sauce over the potatoes. Repeat these layers two more times.
- Bake to Perfection: If you saved cheese, sprinkle the remaining 1/2 cup over the top layer. Cover the dish tightly with aluminum foil and bake for 45 minutes.
- Brown and Rest: After 45 minutes, carefully remove the foil. Continue to bake, uncovered, for another 20-30 minutes, or until the top is golden brown and bubbly and the potatoes are easily pierced with a fork. Finally, let the dish rest for at least 10-15 minutes before serving. This allows the sauce to set.

|---|---|---|
| 1 | Preheat Oven & Prep Dish | Don’t skip buttering the dish; it prevents sticking and adds flavor. |
| 2 | Slice Potatoes | Use a mandoline for perfectly even slices, which ensures even cooking. |

| 4 | Layer Potatoes and Sauce | Spread each layer evenly to ensure every potato slice is coated in sauce. |
| 5 | Bake and Rest | Resting the dish before serving is crucial for the sauce to thicken properly. |
Scalloped Potatoes vs. Potatoes Au Gratin: What’s the Difference?
People often use the terms “scalloped potatoes” and “potatoes au gratin” interchangeably, but there is a traditional difference between them. Although modern recipes frequently blend the two styles, understanding their origins can be helpful. Consequently, you can choose which style you truly want to make.
Traditionally, scalloped potatoes consist of thinly sliced potatoes baked in a simple cream or milk-based sauce. The name “scallop” is believed to refer to the way the potatoes are thinly sliced, resembling the shape of a scallop shell. Cheese was not originally a key ingredient in this dish. On the other hand, potatoes au gratin specifically means potatoes “with a crust.” This classic French dish involves potatoes baked with cheese and often topped with breadcrumbs, which are then browned under a broiler to create a crispy, golden crust. Therefore, the defining feature of au gratin is the cheese and crunchy topping.
Today, however, most American recipes for creamy scalloped potatoes include cheese, just like this one. This hybrid approach gives you the best of both worlds: the velvety sauce of a classic scalloped dish and the savory, cheesy goodness of an au gratin.
What to Serve with Your Scalloped Potatoes
These rich and creamy scalloped potatoes are a show-stopping side dish, but they pair wonderfully with a variety of main courses. Their decadent flavor profile complements both simple weeknight dinners and elaborate holiday feasts. For example, they are a classic companion to a holiday glazed ham or a Thanksgiving turkey. The savory, creamy notes of the potatoes cut through the sweetness of the ham or complement the roasted flavors of the poultry perfectly.
In addition, this potato dish is fantastic alongside a perfectly roasted chicken or a juicy steak. For a balanced meal, you should also consider serving a simple green vegetable. Steamed green beans, roasted asparagus, or a fresh garden salad with a light vinaigrette dressing provide a wonderful contrast in both texture and flavor, preventing the meal from feeling too heavy.
Conclusion About Creamy Scalloped Potatoes
Ultimately, mastering this recipe for creamy scalloped potatoes will make you a hero at any dinner table. By selecting the right potatoes, building a flavorful and stable cream sauce, and slicing your potatoes uniformly, you are setting yourself up for guaranteed success. This dish is the epitome of comfort food, delivering layer upon layer of tender potatoes and rich, cheesy sauce with every bite. It is a timeless classic for a reason, and now you have all the knowledge needed to perfect it in your own kitchen. So, the next time you need a crowd-pleasing side dish, look no further than these incredible creamy scalloped potatoes.
Frequently Asked Questions About Creamy Scalloped Potatoes
Why are my scalloped potatoes watery?
Watery scalloped potatoes are usually caused by one of two things: not using a thickening agent in the sauce or using the wrong type of potato. This recipe solves the first problem by using a flour-based roux to create a thick, stable cream sauce. Moreover, using starchy potatoes like Russets helps release starches during baking, which also contributes to thickening the sauce naturally.
Can I make this recipe ahead of time?
Yes, you can prepare this dish ahead of time. You can assemble the entire casserole, cover it tightly, and refrigerate it for up to two days before baking. To ensure food safety, the FDA advises that perishable foods should not be left out for more than two hours. You may need to add an extra 10-15 minutes to the initial covered baking time to account for the dish being cold from the refrigerator. Alternatively, you can bake it completely, let it cool, and then reheat it before serving.
Can I make these creamy scalloped potatoes gluten-free?
Absolutely. To make this recipe gluten-free, you simply need to substitute the all-purpose flour in the roux. You can use a cup-for-cup gluten-free flour blend or cornstarch. If using cornstarch, you will need about half the amount (2 tablespoons) and should mix it with a little cold milk to create a slurry before adding it to the saucepan to prevent lumps.
