This dish is often found gracing the tables at family gatherings, holidays, and potlucks, cherished for its ability to satisfy and warm the soul. The layers of thinly sliced potatoes are nestled in a velvety sauce, infused with the sharpness of cheddar cheese, creating a harmonious blend of textures and flavors.

Historical Background

Scalloped potatoes, originally known as “gratin dauphinois” in French cuisine, have a long-standing history as a beloved side dish. The term “scalloped” is believed to derive from the Old English word “collops,” which referred to slices or portions of meat, eventually extending to thinly sliced potatoes. Traditionally, scalloped potatoes were made with just cream and butter, but over time, cheese was introduced into the recipe, adding an extra layer of richness and flavor. This adaptation has turned scalloped potatoes into a quintessential comfort food in many cultures, especially in American and European households.

Purpose of the Recipe

This recipe for cheesy scalloped potatoes is designed for those who crave a dish that is not only creamy and indulgent but also easy to prepare. It’s a must-try for anyone who appreciates the simple pleasures of comfort food, offering a perfect balance of flavors and textures. Whether you’re cooking for a special occasion or just a cozy dinner at home, this dish will quickly become a favorite in your culinary repertoire. The combination of tender potatoes, sweet onions, and a rich, cheesy sauce makes it a versatile side that pairs beautifully with a wide range of main courses, from roasted meats to grilled vegetables.

Ingredients Breakdown

Potatoes
Russet potatoes are the ideal choice for this recipe due to their high starch content and low moisture. These characteristics allow the potatoes to break down slightly during cooking, creating a tender, almost creamy texture that complements the rich cheese sauce. Their slightly fluffy nature helps them absorb the flavors of the sauce, making each bite flavorful and satisfying. If russet potatoes are unavailable, Yukon Gold potatoes can be a good alternative, offering a buttery flavor and smooth texture.

Onions
Yellow onions are chosen for their balanced sweetness and sharpness, which enhances the overall flavor of the dish. As they cook, the onions caramelize slightly, adding a subtle sweetness that contrasts beautifully with the savory cheese sauce. For a milder flavor, sweet onions or shallots can be used instead, bringing a gentler taste to the dish. These alternatives will still provide the necessary flavor depth without overpowering the creamy sauce.

Butter and Flour
Creating a roux with butter and flour is a crucial step in making the cheese sauce. The roux acts as a thickening agent, ensuring the sauce achieves the right consistency without becoming too heavy. To perfect the roux, cook the butter and flour mixture just until it starts to turn a pale golden color, which indicates the flour is cooked and will not impart a raw taste to the sauce. Be careful not to overcook, as this can lead to a bitter flavor.

Cheddar Cheese
Mild cheddar cheese is selected for its creamy texture and balanced flavor, which melts smoothly into the sauce without becoming greasy. It provides a rich, comforting taste that complements the potatoes without overwhelming them. If you prefer a stronger flavor, sharp cheddar or Gruyere can be substituted, offering a more intense cheesy experience. These cheeses will add a distinctive tang or nutty undertone to the dish.

Milk
Whole milk is used in this recipe for its full-fat content, which contributes to the creaminess of the sauce. The fat in whole milk helps create a smooth, luscious sauce that coats the potatoes evenly. Using lower-fat milk, such as 2% or skim, may result in a thinner sauce, while plant-based milks like almond or oat can be used for a dairy-free version, though they might slightly alter the flavor and texture.

Seasonings
Kosher salt and pepper are essential for enhancing the natural flavors of the ingredients, ensuring the dish isn’t bland. The larger grains of kosher salt make it easier to control seasoning levels, while freshly ground black pepper adds a slight kick. Additional seasonings like garlic powder, paprika, or even a pinch of nutmeg can be incorporated to add depth and complexity to the flavor profile, making the dish uniquely yours.

Step-by-Step Instructions

Preparation
Start by preparing the potatoes and onions. Peel the russet potatoes and slice them into uniform ¼-inch thick rounds. Uniform slicing is crucial for even cooking; using a mandoline slicer can help achieve consistent thickness. For the onions, peel and slice them into thin rings. The thinness of the slices ensures they cook through at the same rate as the potatoes, blending seamlessly into the dish.

Making the Cheese Sauce

Melting the Butter: In a medium-sized saucepan, melt 3 tablespoons of unsalted butter over medium heat. Keep a close eye on the butter as it melts to avoid burning. Swirl the pan gently or stir the butter as it melts to ensure it cooks evenly. The goal is to melt the butter until it’s fully liquid and begins to bubble lightly.
Creating the Roux: Once the butter is melted, add 3 tablespoons of all-purpose flour. Stir continuously with a whisk to combine the flour and butter, creating a smooth paste. Cook the mixture for about 1 minute, or until it turns a pale golden color. This cooking process eliminates the raw flour taste but be careful not to let the roux darken too much, as this can impart a bitter flavor.
Adding the Milk: Gradually pour in 2 cups of room-temperature whole milk while continuing to whisk. Adding the milk slowly prevents lumps from forming and ensures a smooth sauce. Whisk constantly as you pour to keep the roux and milk well combined. Continue cooking the mixture over medium heat, stirring frequently, until it thickens, which should take about 5-7 minutes.

Incorporating Cheese: Once the sauce has thickened, remove it from the heat and stir in 1 ½ cups of shredded mild cheddar cheese all at once. Stir continuously until the cheese is completely melted and the sauce is smooth. Avoid returning the sauce to heat after adding the cheese, as this can cause the cheese to curdle and separate.

Assembling the Dish

Layering Potatoes and Onions: Preheat your oven to 400°F. Lightly spray an 8×8-inch casserole dish with nonstick cooking spray. Arrange a layer of potato slices in the bottom of the dish, slightly overlapping them. Follow with a layer of onion rings. Continue layering until all the potatoes and onions are used, finishing with a layer of potatoes on top.

Pouring the Cheese Sauce: Pour the prepared cheese sauce evenly over the layered potatoes and onions, ensuring it covers all the slices. Use a spatula to spread the sauce evenly, allowing it to seep through the layers and coat the potatoes.
Baking Instructions: Cover the dish with aluminum foil and bake in the preheated oven for 85-90 minutes, or until the potatoes are tender when pierced with a fork. The long baking time ensures the potatoes become tender and fully absorb the flavors of the sauce.
Optional Broiling: For a crispy, golden-brown top, remove the foil after baking and switch the oven setting to broil. Broil the dish for 2-3 minutes, watching closely to avoid burning. The top should turn a beautiful golden color, adding a satisfying crunch to the creamy dish.

Serving Suggestions and Variations

Serving Suggestions
Cheesy scalloped potatoes are a versatile side dish that pairs wonderfully with a variety of main courses. For a classic combination, serve them alongside roast meats such as beef, pork, or chicken. The rich, creamy potatoes complement the robust flavors of these proteins. For a lighter meal, pair the potatoes with a fresh green salad dressed in a tangy vinaigrette, which cuts through the richness of the dish and adds a refreshing contrast. They also work well with grilled vegetables, offering a satisfying balance between textures and flavors.

Recipe Variations

Adding Protein: To make the dish more substantial, consider adding cooked ham, crispy bacon, or sausage slices. These proteins can be layered between the potatoes and onions, infusing the dish with savory flavors. Ham adds a subtle sweetness, bacon brings a smoky crunch, and sausage introduces a spiced element, turning the side dish into a heartier, more filling main course.

Alternative Cheeses: Experiment with different cheeses to create varied flavor profiles. Sharp cheddar or Gruyere will give the dish a more pronounced, tangy flavor, while a mix of Parmesan and mozzarella can create a creamier, more delicate taste with a slightly nutty undertone. Blue cheese or feta can also be added in small amounts for a bold, distinctive twist.
Vegan/Dairy-Free Options: For a dairy-free version, substitute the butter with plant-based butter and use almond or oat milk instead of whole milk. Vegan cheese, made from cashews or coconut, can replace the cheddar, providing a similar creamy texture and flavor. Nutritional yeast can be added for a cheesy flavor boost without the dairy.
Herbs and Spices: Elevate the dish by incorporating fresh herbs like thyme, rosemary, or chives. These herbs can be sprinkled between the layers or added to the cheese sauce, infusing the dish with fragrant, earthy notes. A pinch of garlic powder, paprika, or even cayenne pepper can also be added to the sauce to introduce subtle layers of complexity and warmth to the flavor profile.

Tips for Perfect Cheesy Scalloped Potatoes

Choosing the Right Potatoes
When selecting potatoes for scalloped potatoes, it’s essential to choose varieties with high starch content, like russet or Yukon Gold. Russet potatoes are particularly ideal because their starchiness breaks down during cooking, creating a soft, tender texture that absorbs the cheese sauce beautifully. When shopping, look for firm, unblemished potatoes with smooth skins. Avoid potatoes with green spots or sprouting eyes, as these indicate the potato is past its prime and may not cook evenly.

Cheese Selection Tips
The cheese you choose will greatly influence both the texture and flavor of the dish. Mild cheddar is often preferred for its smooth melting qualities and balanced flavor, but don’t be afraid to experiment. Aged cheeses, like sharp cheddar or Gruyere, bring more intense flavors but may not melt as smoothly. If you opt for a mix of cheeses, ensure they are good melters to avoid a grainy sauce. Always grate the cheese yourself rather than using pre-shredded varieties, as the latter often contains anti-caking agents that can affect the texture of the sauce.

Preventing a Curdled Sauce
One of the most common issues in making cheesy scalloped potatoes is a curdled sauce. To prevent this, ensure that the milk is at room temperature before adding it to the roux. Gradually incorporating the milk while constantly whisking helps create a smooth base. After adding the cheese, do not return the sauce to high heat, as this can cause the cheese to separate. Instead, melt the cheese gently off the heat for a creamy, cohesive sauce.

Ensuring Even Cooking
To ensure all potato slices cook evenly, slice them to a uniform thickness, ideally about ¼-inch thick. A mandoline slicer can be helpful here. When layering the potatoes in the dish, try to overlap them slightly, which promotes even cooking. Make sure the cheese sauce is evenly distributed across the layers to avoid dry spots. If the potatoes on top seem to be cooking faster than those underneath, cover the dish with foil for the first portion of the baking time, then remove it to allow the top to brown.

Achieving the Perfect Crust
The hallmark of a great scalloped potato dish is a crispy, golden-brown crust. To achieve this, finish the dish under the broiler for a few minutes after it has baked fully. Keep a close eye on it to prevent burning. For an extra-crispy top, you can sprinkle a thin layer of breadcrumbs or extra cheese over the potatoes before broiling. This will add a satisfying crunch to the creamy layers beneath.

FAQs

Why did my cheese sauce curdle?
Your cheese sauce likely curdled due to overheating. High temperatures can cause the proteins in the cheese to separate from the fat, leading to a grainy, curdled texture. To prevent this, always add the cheese to the sauce off the heat, stirring until it melts smoothly. Also, ensure that the milk is at room temperature when you add it to the roux, and avoid bringing the sauce to a boil after the cheese is added.

Can I use a different type of potato?
Yes, you can use different types of potatoes, but the texture of the final dish may vary. Yukon Gold potatoes are a good alternative to russets as they have a creamy texture and hold their shape well during cooking. However, waxy potatoes like red or new potatoes are less starchy and won’t break down as much, leading to a firmer texture in the finished dish.

How can I make this dish ahead of time?
You can prepare the dish up to the baking step and store it in the refrigerator for up to 24 hours. Assemble the layers and pour the cheese sauce over the potatoes, then cover the dish tightly with plastic wrap or foil. When ready to bake, remove the dish from the fridge and let it come to room temperature before baking, adding an extra 10-15 minutes to the baking time.

What’s the best way to reheat leftovers?
To reheat leftovers, cover the dish with foil and warm it in a 350°F oven for about 20-30 minutes, or until heated through. For a quicker option, individual portions can be microwaved. To maintain the crispy top, reheat uncovered in the oven during the last 5 minutes.

Can I freeze cheesy scalloped potatoes?
Yes, you can freeze cheesy scalloped potatoes, but the texture may change slightly upon reheating. To freeze, bake the dish as directed, cool completely, then wrap it tightly in plastic wrap and aluminum foil. Freeze for up to 3 months. Thaw in the refrigerator overnight before reheating in the oven.

How do I prevent my potatoes from turning gray?
Potatoes can turn gray if exposed to air for too long after slicing. To prevent this, immediately submerge the sliced potatoes in cold water until you’re ready to layer them in the dish. Drain and pat them dry before assembling the layers to remove excess moisture.

What can I add to make this dish more flavorful?
To enhance the flavor, consider adding fresh herbs like thyme or rosemary, which pair well with the richness of the cheese. Garlic powder, onion powder, or a pinch of nutmeg can also be added to the cheese sauce for extra depth. For a bit of heat, try adding a dash of cayenne pepper or paprika.
