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
Cooking Instructions
- Prepare the Potatoes and Onions: Begin by preparing your vegetables. Peel the russet potatoes and slice them into uniform ¼-inch thick rounds. Consistency in slicing is key here; it ensures that all the potato slices cook evenly. A mandoline slicer can be a great tool for achieving perfectly uniform slices, but a sharp knife works beautifully too. Once sliced, you can rinse the potatoes under cold water to remove excess starch, which helps prevent them from sticking together, and then pat them thoroughly dry with paper towels. Set them aside. Next, slice your yellow onion into thin rings. The onion will soften and sweeten as it bakes, adding a delightful depth of flavor to the dish.
- Start the Cheese Sauce: In a medium saucepan, melt the 3 tablespoons of unsalted butter over medium heat. Once the butter is fully melted and starts to lightly sizzle, whisk in the 3 tablespoons of all-purpose flour. This mixture, known as a roux, is the base of our creamy sauce. Cook the roux for about 1 to 2 minutes, stirring constantly. You want to cook out the raw flour taste without letting it brown significantly. It should look like a thick paste. This step is crucial for a smooth, lump-free sauce, so don’t rush it.
- Whisk in the Milk and Seasonings: Gradually whisk in the 2 cups of room temperature whole milk, a little at a time. It’s important to add the milk slowly and whisk continuously to prevent lumps from forming. As you add the milk, the sauce will start to thicken. Once all the milk has been incorporated, add the ½ teaspoon of kosher salt. Continue to cook, stirring frequently, over medium-low heat until the sauce has thickened enough to coat the back of a spoon. This usually takes about 5-7 minutes. Don’t let it boil vigorously; a gentle simmer is perfect.
- Melt in the Cheese and Adjust Seasoning: Remove the saucepan from the heat and stir in the 1 ½ cups of shredded mild cheddar cheese. Continue stirring until the cheese is completely melted and the sauce is smooth and glossy. The mild cheddar provides a creamy, cheesy flavor without overpowering the potatoes. Taste the sauce and add salt and pepper as needed. Remember that the cheese itself can be salty, so season cautiously. This cheese sauce is the heart of our scalloped potatoes, so make sure it’s perfectly seasoned to your liking.
- Assemble and Bake: Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. Begin by layering about one-third of the sliced potatoes and onion rings evenly across the bottom of the prepared dish. Pour about one-third of the cheese sauce over the potato and onion layer. Repeat these layers two more times, ending with a layer of sauce on top. Ensure that all the potatoes are covered with sauce to prevent them from drying out during baking. Cover the baking dish tightly with aluminum foil. Bake for 45 minutes. After 45 minutes, carefully remove the foil and continue baking for another 15-20 minutes, or until the potatoes are tender when pierced with a fork and the top is golden brown and bubbly. If you like a crispier top, you can briefly place the dish under the broiler for the last 1-2 minutes, watching it very closely to prevent burning. Let the scalloped potatoes rest for about 10 minutes before serving. This allows the sauce to set slightly, making it easier to serve and ensuring that wonderfully creamy texture.

Frequently Asked Questions:
Q: Can I make these Cheesy Scalloped Potatoes ahead of time?
A: Absolutely! You can assemble the scalloped potatoes up to a day in advance, cover them tightly, and refrigerate. When you’re ready to bake, you may need to add an extra 10-15 minutes to the baking time to ensure they are heated through completely.
Q: My sauce seems a bit thin. What can I do?
A: If your sauce is thinner than you’d like, it will thicken as it bakes and the starches from the potatoes are released. However, if it’s still too thin after baking, you can always broil the dish for a few minutes until the cheese is bubbly and slightly browned, which helps to further thicken the sauce.
Q: What kind of potatoes are best for scalloped potatoes?
A: Waxy potatoes like Yukon Golds or red potatoes hold their shape well during baking and absorb the creamy sauce beautifully, resulting in a delightful texture. While starchy potatoes like Russets can be used, they might break down more easily, creating a starchier, less defined layer.
