Best Ever Scalloped Potatoes: Creamy, Cheesy Side Dish

Scalloped Potatoes hold a truly special place at any dinner table, transforming humble potatoes into an extraordinary side dish that consistently steals the show. Have you ever experienced that moment when a spoonful reveals layers of perfectly tender potato, swimming in a luxurious, creamy sauce, all crowned with a golden, bubbly top? That’s the irresistible allure we’re talking about! I find it simply magical how such a simple combination of ingredients can create something so deeply satisfying and utterly delicious.

The Enduring Appeal of a Classic

While often associated with American holiday feasts and potlucks, the tradition of baking sliced vegetables in cream or cheese has roots stretching back to European gratins. This timeless cooking method has evolved over centuries, culminating in the beloved dish we know today. People adore this recipe not just for its incredible taste – the savory depth of the cream and often a hint of garlic or onion – but also for its wonderful textural contrast: the soft, yielding potatoes against the occasional crisp edge. It’s the ultimate comfort food, a warm hug on a plate, and a guaranteed crowd-pleaser that pairs beautifully with almost any main course. Preparing a classic batch of Scalloped Potatoes is an act of culinary love, and the reward is always worth it.

this Recipe

Ingredients:

• 2.5 to 3 pounds Yukon Gold or Russet potatoes (approximately 5-6 medium potatoes), peeled and uniformly sliced very thin (about 1/8-inch thick). A mandoline slicer is highly recommended for consistency.
• 4 tablespoons (1/2 stick) unsalted butter, divided
• 2 cloves garlic, minced or finely grated
• 1 small yellow onion, very finely diced (almost a paste, if possible) or grated
• 3 tablespoons all-purpose flour (this helps thicken our glorious cream sauce)
• 2 cups heavy cream (for that rich, luxurious texture that defines perfect scalloped potatoes)
• 1 cup whole milk
• 1.5 teaspoons fine sea salt, or to taste
• 1/2 teaspoon freshly ground black pepper, or to taste
• 1/4 teaspoon freshly grated nutmeg (this is a secret weapon for cream-based dishes)
• Pinch of cayenne pepper (optional, but adds a wonderful, subtle warmth without making it spicy)
• 1/2 teaspoon dried thyme (optional, but complements the potatoes beautifully)
• Fresh parsley or chives, finely chopped, for garnish (optional)
• 1 cup shredded Gruyere or sharp white cheddar cheese (optional, for a cheesy topping, though traditional scalloped potatoes are often cheeseless in the layers)

Preparation of Potatoes and Aromatics

1. Preheat Your Oven: My first step is always to get the oven ready. Set it to 375°F (190°C). This allows it to heat up fully and evenly by the time our beautiful dish is ready for baking.
2. Prepare the Potatoes: This is a crucial step for truly amazing scalloped potatoes.
   
   First, wash and peel your chosen potatoes. I highly recommend Yukon Golds for their buttery texture and how well they hold their shape, or Russets if you prefer a slightly starchier, fluffier result.
   
   Next, and this is perhaps the most important part for classic scalloped potatoes, you need to slice them very, very thinly and uniformly. We’re aiming for about 1/8-inch thick. A mandoline slicer is your best friend here; it creates consistent slices that cook evenly and stack beautifully, giving you that iconic layered look. If you don’t have one, a very sharp knife and a steady hand will work, but take your time. Uniformity is key for perfectly tender, melt-in-your-mouth scalloped potatoes.
   
   Once sliced, immediately place them in a large bowl of cold water. This helps to prevent discoloration and removes some of the excess starch, which can make the sauce gummy. You’ll want to keep them submerged until you’re ready to layer, then drain them thoroughly and pat them very dry with a clean kitchen towel or paper towels. Excess moisture can dilute your delicious cream sauce.
3. Sauté the Aromatics: In a medium saucepan or a deep skillet, melt 2 tablespoons of the unsalted butter over medium heat. Once shimmering, add your finely diced yellow onion. Cook gently for about 5-7 minutes, stirring occasionally, until the onion becomes translucent and very tender. You’re not looking for color here, just softness and a release of its sweet aroma. The smaller you dice the onion, the more it will melt into the sauce, providing flavor without noticeable chunks.
   
   Next, add your minced garlic to the pan. Cook for another minute, stirring constantly, until fragrant. Be careful not to burn the garlic; burnt garlic can turn bitter and ruin the delicate flavor of your scalloped potatoes. This aromatic base is what gives our cream sauce its incredible depth.

Crafting the Creamy Sauce

4. Make the Roux: Sprinkle the 3 tablespoons of all-purpose flour over the cooked onions and garlic in the saucepan. Stir continuously for 1-2 minutes, allowing the flour to cook out and form a thick paste with the butter and aromatics. This is called a roux, and it’s what will thicken our sauce beautifully, ensuring it clings perfectly to every potato slice.
5. Whisk in Dairy: Gradually, and I mean gradually, whisk in the heavy cream and whole milk. Start by adding a small amount of liquid, whisking vigorously until it’s fully incorporated and smooth before adding more. This prevents lumps and ensures a silky-smooth sauce. Continue adding the cream and milk in small increments, whisking until the sauce is completely smooth and lump-free.
   
   Once all the dairy is incorporated, increase the heat slightly and bring the sauce to a gentle simmer, stirring constantly. Let it simmer for about 2-3 minutes, or until it has noticeably thickened. It should be thick enough to coat the back of a spoon. This thickening process is essential for making sure your scalloped potatoes are creamy and not watery.
6. Season the Sauce: Remove the saucepan from the heat. Now it’s time to flavor our gorgeous cream sauce! Stir in the 1.5 teaspoons of fine sea salt, 1/2 teaspoon of freshly ground black pepper, the 1/4 teaspoon of freshly grated nutmeg, and the pinch of cayenne pepper (if you’re using it). If you’re using dried thyme, add it now too. Taste the sauce and adjust seasonings as needed. Remember, the potatoes themselves won’t be seasoned, so the sauce needs to carry all the flavor. It should taste slightly saltier than you think, as the potatoes will absorb a lot of it. This well-seasoned sauce is the heart and soul of perfect scalloped potatoes.

Assembling the Scalloped Potatoes

7. Prepare Your Baking Dish: Generously grease a 9×13-inch baking dish (or a similar 3-quart oven-safe dish) with the remaining 2 tablespoons of unsalted butter. Make sure to get all the corners and sides to prevent sticking and encourage a beautiful golden crust. This also imparts another layer of buttery flavor.
8. Layer the Potatoes: Now for the artistic part! Arrange a single layer of your thinly sliced potatoes in the bottom of the prepared baking dish, slightly overlapping each slice like shingles. Try to make this layer as even as possible. This first layer sets the foundation for your scalloped potatoes.
   
   Pour about one-third of your creamy sauce evenly over this potato layer. Use a spoon or a small ladle to ensure every potato slice gets coated.
   
   Repeat this process: create another layer of potatoes, overlapping them, and then cover with another third of the cream sauce.
   
   Finally, add the last layer of potatoes. Pour the remaining cream sauce over the top, making sure to spread it evenly so all the potatoes are submerged or very well coated. Gently shake the dish a bit to help the sauce settle into any crevices.
   
   If you are adding cheese: This is the point where you would sprinkle your shredded Gruyere or sharp white cheddar evenly over the top layer of potatoes and sauce. While not strictly traditional for scalloped potatoes (which are distinct from potatoes au gratin, which feature cheese between layers), a cheesy topping adds a delightful golden crust and extra flavor.

Baking to Golden Perfection

9. Cover and Bake: Loosely cover the baking dish with aluminum foil. This initial covered baking period allows the potatoes to steam and cook through without drying out or browning too quickly.
   
   Place the dish in your preheated 375°F (190°C) oven and bake for 45 minutes to 1 hour. The exact time will depend on the thickness of your potato slices. After this time, carefully remove the foil. The potatoes should be starting to soften, and the sauce should be bubbly.
10. Uncover and Brown: Return the uncovered dish to the oven. Continue baking for another 30-45 minutes, or until the potatoes are completely tender when pierced with a fork (the fork should slide in with almost no resistance) and the top is beautifully golden brown and bubbly. If you added cheese, it should be melted, bubbly, and beautifully caramelized. If you notice the top browning too quickly but the potatoes aren’t yet tender, you can loosely tent it with foil again. This second baking phase is crucial for developing that irresistible golden crust and fully cooking the scalloped potatoes through.

Resting and Serving

11. The Essential Rest: This step is often overlooked, but it’s incredibly important for perfect scalloped potatoes. Once baked, remove the dish from the oven and let it rest on a wire rack for at least 15-20 minutes (or even up to 30 minutes) before serving.
    
    Why rest? During baking, the sauce is very hot and fluid. Resting allows the sauce to cool slightly, thicken further, and reabsorb into the potatoes. This prevents the dish from falling apart when you serve it, ensuring clean, intact portions and a truly creamy texture. If you try to serve it immediately, the sauce will run everywhere, and the potatoes will be too soft to hold their shape.
12. Garnish and Serve: If desired, sprinkle your perfectly baked scalloped potatoes with some fresh chopped parsley or chives just before serving. This adds a lovely pop of color and freshness.
    
    Serve warm as a truly indulgent side dish to roasted meats, poultry, or fish. These classic scalloped potatoes are comforting, rich, and guaranteed to be a crowd-pleaser. They are the epitome of simple ingredients transformed into something extraordinary.

Tips for the Best Scalloped Potatoes

• Potato Choice Matters: For truly exceptional scalloped potatoes, choose the right variety. Yukon Gold potatoes are my top recommendation. They have a naturally buttery flavor, a medium starch content, and hold their shape beautifully, resulting in a creamy yet structured dish. Russet potatoes can also be used, but they tend to be starchier and can make the sauce slightly thicker and less translucent; they also fall apart a bit more. Avoid waxy potatoes like red bliss or new potatoes, as they won’t absorb the sauce as well and can result in a firmer, less tender texture.
• Uniform Slicing is Non-Negotiable: I cannot stress this enough: consistency is key. Every single potato slice should be the same thickness, ideally 1/8-inch. This ensures that all potatoes cook evenly at the same rate, preventing some from being undercooked while others are mushy. A mandoline slicer is truly worth the investment for this dish alone. If slicing by hand, take your time and aim for precision.
• Seasoning is Everything: Remember, potatoes themselves are bland. The cream sauce needs to be perfectly seasoned to carry all the flavor. Don’t be shy with salt and pepper, and taste your sauce before layering. The nutmeg and a tiny pinch of cayenne are subtle additions that elevate the flavor profile immensely without being overpowering.
• Warm the Milk and Cream: While the recipe has you create a roux and then add dairy, for an even smoother sauce and to reduce cooking time slightly, you can gently warm the milk and cream in a separate saucepan before adding it to the roux. This also helps prevent the sauce from seizing up.
• Don’t Skimp on Dairy: For truly rich and luxurious scalloped potatoes, heavy cream is a must. While you can use a combination of milk and cream, entirely substituting with low-fat milk will result in a much thinner, less decadent sauce. This is a dish meant for indulgence!
• The Power of the Rest: As mentioned in the steps, letting the dish rest after baking is paramount. It allows the starches to set, the sauce to thicken and absorb, and the flavors to meld. If you cut into it too soon, it will be a soupy mess. Patience is rewarded with perfectly cohesive and creamy slices of scalloped potatoes.
• Prevent Over-Browning: If your scalloped potatoes are browning too quickly on top before the potatoes are tender, simply tent the dish loosely with aluminum foil for the remainder of the baking time.

Variations and Customizations for Your Scalloped Potatoes

• Cheesy Scalloped Potatoes: While classic scalloped potatoes don’t typically include cheese between the layers (that’s often the distinction of Potatoes Au Gratin), adding a cheesy topping is a popular and delicious modification. As noted, you can sprinkle 1 cup of shredded Gruyere, sharp white cheddar, or even Parmesan cheese over the top layer before the final uncovered baking period. The cheese will melt into a golden, bubbly crust, adding another dimension of flavor and texture.
• Herbaceous Delight: Beyond thyme, experiment with other herbs! A small amount of fresh rosemary, finely minced, can add an earthy, aromatic note. Fresh sage, also finely chopped, pairs wonderfully with potatoes and cream. Add these directly into your cream sauce as it simmers.
• Smoky Flavors: For a subtle smoky depth, consider adding a pinch of smoked paprika to your cream sauce. You could also render a slice or two of bacon or pancetta until crispy, crumble it, and sprinkle it between potato layers or over the top. The rendered fat could even be used to sauté the onions and garlic, imparting even more flavor.
• Spice It Up: If you enjoy a bit more heat, increase the amount of cayenne pepper, or add a pinch of red pepper flakes to the cream sauce.
• Different Aromatics: While onion and garlic are standard, you could try using shallots instead of or in addition to the onion for a milder, sweeter flavor. A tiny splash of dry white wine (like Chardonnay or Pinot Grigio) can be deglazed into the pan after sautéing the aromatics before adding the flour, which adds a lovely subtle acidity and complexity to the sauce. Ensure it’s fully reduced before proceeding.
• Make Ahead Options: You can assemble the scalloped potatoes the day before baking. Once assembled, cover the dish tightly with plastic wrap and refrigerate. Before baking, let it sit at room temperature for about 30 minutes to an hour to take the chill off, then bake as directed, adding an extra 10-15 minutes to the covered baking time if needed.
• Freezing and Reheating: Baked scalloped potatoes freeze surprisingly well. Once cooled completely, you can portion them into freezer-safe containers or wrap the entire dish tightly in foil and plastic wrap. Freeze for up to 3 months. To reheat, thaw overnight in the refrigerator, then bake in a preheated oven at 350°F (175°C) until heated through and bubbly, covering if necessary to prevent over-browning. Individual portions can also be reheated gently in the microwave.

These scalloped potatoes are more than just a side dish; they are a truly comforting culinary experience, a testament to how simple ingredients can create something profoundly delicious. Whether you stick to the classic or explore variations, you’re in for a treat!
