This recipe is a classic for a reason, and once you try it, I’m sure it will become a favorite in your kitchen too. Let’s get started on creating this culinary masterpiece!
Ingredients:
- 4 russet potatoes, peeled and sliced into ¼-inch slices (about 2 pounds)
- 1 yellow onion, sliced into rings
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- ½ teaspoon kosher salt
- 2 cups whole milk, room temperature
- 1 ½ cups mild cheddar cheese, shredded
- salt and pepper to taste
Preparing the Potatoes and Onions
The first step in creating our delicious scalloped potatoes is to prepare our main ingredients. We want to peel the russet potatoes to ensure a smooth, creamy texture without any tough skins. Once peeled, slice them into uniform ¼-inch thick rounds. This consistency is key for even cooking. If your slices are too thick, they might not soften sufficiently, and if they’re too thin, they could turn mushy. You can use a mandoline for perfect uniformity, but a sharp knife and a steady hand will do the trick just fine. After slicing, it’s a good idea to rinse the potato slices under cold water. This helps to remove excess starch, which can prevent the sauce from becoming too gluey. Pat them thoroughly dry with paper towels; this is important to prevent the sauce from becoming watery. Next, we’ll slice the yellow onion into rings. The gentle sweetness of the yellow onion will complement the richness of the potatoes and cheese beautifully. If you prefer a milder onion flavor, you can soak the onion rings in cold water for about 10 minutes before patting them dry, then proceed with the recipe.
Crafting the Creamy Cheese Sauce
Now, let’s move on to creating the luscious, cheesy sauce that makes these scalloped potatoes so irresistible. We’ll start by melting the unsalted butter in a medium saucepan over medium heat. Once the butter is melted and shimmering, we’ll whisk in the all-purpose flour. This mixture, often called a roux, is the foundation of our creamy sauce. We want to cook the roux for about 1 to 2 minutes, stirring constantly. This step is important because it toasts the flour, removing any raw flour taste and thickening the sauce effectively. You’ll notice it will start to smell slightly nutty. Be careful not to let it brown too much, as we want a pale roux for a light-colored sauce.
After the roux has cooked for a couple of minutes, it’s time to gradually whisk in the room-temperature whole milk. Adding the milk slowly, a little at a time, while continuously whisking, will help prevent lumps from forming. Continue to whisk until all the milk is incorporated and the sauce begins to thicken. This usually takes about 5-7 minutes. Once the sauce has reached a smooth, creamy consistency, it’s time to add our seasonings. Stir in the ½ teaspoon of kosher salt. Now, reduce the heat to low. We’ll gently stir in the shredded mild cheddar cheese, a handful at a time, allowing each addition to melt completely before adding more. Keep stirring until the cheese is fully melted and the sauce is smooth and glossy. Taste the sauce at this point and add salt and pepper as needed. Remember that the cheese itself is salty, so season cautiously. The sauce should be thick enough to coat the back of a spoon. If it’s too thick, you can whisk in a tablespoon or two more milk. If it seems too thin, let it simmer gently for another minute or two, stirring constantly.
Assembling and Baking to Golden Perfection
With our creamy sauce ready and our potatoes and onions prepped, it’s time to assemble our scalloped potatoes. Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with butter or cooking spray. This will prevent the potatoes from sticking to the bottom and sides of the dish, ensuring they release beautifully once cooked. Now, we’ll layer the ingredients. Start with a layer of the potato slices, arranging them evenly across the bottom of the baking dish. Don’t worry if there’s a slight overlap. Next, scatter half of the sliced onion rings over the potatoes. Then, pour about one-third of the cheesy sauce evenly over this layer. Repeat the layering process: another layer of potatoes, the remaining onion rings, and another third of the sauce. Finally, top with the last layer of potato slices and pour the remaining cheesy sauce over the top, making sure to cover all the potatoes. You can gently shake the dish to help the sauce settle evenly.
Now, it’s time to bake our cheesy scalloped potatoes. Cover the baking dish tightly with aluminum foil. This is crucial for the first part of the baking process as it traps the steam, allowing the potatoes to cook through evenly and become tender without the top browning too quickly. Place the covered dish in the preheated oven and bake for 45 minutes. After 45 minutes, carefully remove the aluminum foil. You’ll see the sauce is bubbling gently. Continue to bake, uncovered, for another 20-25 minutes, or until the top is beautifully golden brown and bubbly, and the potatoes are tender when pierced with a fork. A toothpick or a sharp knife should slide easily through the potatoes.
Resting and Serving
Once your cheesy scalloped potatoes are out of the oven and looking absolutely divine, it’s incredibly tempting to dig in immediately. However, I highly recommend letting them rest for about 10-15 minutes before serving. This resting period is essential. It allows the sauce to set up slightly, making it easier to serve neat portions and preventing a watery mess. The flavors also have a chance to meld together further during this time, enhancing the overall taste of the dish. Serve hot, garnished with a sprinkle of fresh parsley if you like, for a pop of color. This dish is a fantastic accompaniment to roasted meats, grilled chicken, or even a simple green salad. Enjoy every creamy, cheesy, potato-y bite!

Frequently Asked Questions:
Can I make Cheesy Scalloped Potatoes ahead of time?
Yes, you absolutely can! You can assemble the potatoes and sauce a day in advance and store them covered in the refrigerator. When you’re ready to bake, add a little extra liquid (like milk or cream) if the mixture seems too thick, and bake as directed, potentially adding a few extra minutes to account for the chill.
What kind of potatoes are best for scalloped potatoes?
Waxy potatoes like Yukon Gold or red potatoes are generally preferred for scalloped potatoes. They hold their shape well during the baking process, preventing them from becoming mushy, and they absorb the creamy sauce beautifully.
