Best Creamy Scalloped Potatoes Recipe – Perfect Side Dish

The Irresistible Allure of Scalloped Potatoes

Scalloped Potatoes: just the name evokes images of creamy, tender potato slices bathed in a rich, savory sauce, baked until bubbling and golden. I truly believe that if there’s one dish that consistently steals the spotlight at any dinner table, it’s this ultimate comfort food masterpiece. There’s an undeniable magic in layering thinly sliced potatoes, transforming humble ingredients into something truly extraordinary. For me, it’s more than just a side dish; it’s a culinary hug, a dish that brings warmth and joy to every single forkful.

The origins of dishes similar to scalloped potatoes can be traced back to European gratin traditions, where ingredients were baked in a shallow dish, often topped with cheese or breadcrumbs to create a delightful crust. Over generations, this preparation evolved into the beloved American classic we know today, becoming a staple at holiday feasts and family gatherings alike. I think people adore this dish for its incredible texture — the melt-in-your-mouth tenderness of the potatoes perfectly contrasted with the creamy, often cheesy, sauce. Its versatility also makes it a personal favorite; it pairs beautifully with everything from a simple roasted chicken to an elegant holiday ham.

Whether you’re reminiscing about your grandmother’s recipe or simply craving a genuinely satisfying meal, I promise you, mastering perfect Scalloped Potatoes is a culinary skill well worth acquiring. I’m so excited to guide you through creating a dish that promises to impress and satisfy with its timeless appeal.

this Recipe

Ingredients:

• 2.5 pounds (about 5-6 medium) Russet or Yukon Gold Potatoes: I often lean towards Yukon Golds for their slightly waxier texture and buttery flavor, which holds its shape beautifully while still becoming incredibly tender. Russets work wonderfully too, offering a starchier profile that can absorb more of that luscious cream sauce, creating an even thicker, more comforting scalloped potatoes dish.
• 4 tablespoons unsalted butter: Divided. We’ll use some for the roux and some to butter the dish. Unsalted allows us to control the seasoning precisely.
• 4 cloves garlic: Minced very finely. Garlic adds a wonderful aromatic depth that truly elevates the flavor profile of these scalloped potatoes.
• 1/2 cup finely chopped yellow onion or 2 shallots: While optional, I find that a little bit of onion or shallot, cooked until translucent, provides a foundational sweetness and complexity that complements the potatoes and cream exquisitely. Shallots are my personal preference for a milder, more refined onion flavor.
• 1/4 cup all-purpose flour: This is our thickening agent for the sauce, creating a smooth, rich base for the scalloped potatoes.
• 2 cups whole milk: Whole milk provides a good balance of richness and liquid for our sauce. Make sure it’s whole milk; skim milk simply won’t yield the same luxurious texture.
• 2 cups heavy cream: This is where the magic truly happens! Heavy cream is essential for that undeniably rich, velvety texture that defines perfect scalloped potatoes. Don’t skimp on it; it’s what makes this dish so incredibly decadent.
• 1.5 teaspoons fine sea salt: Or to taste. Potatoes need a good amount of seasoning!
• 1/2 teaspoon freshly ground black pepper: Again, adjust to your preference.
• 1/4 teaspoon freshly grated nutmeg: This is my secret ingredient for scalloped potatoes! Nutmeg beautifully enhances the flavors of dairy and potatoes, adding a subtle warmth and depth that you might not even pinpoint but will definitely notice. It’s truly transformative.
• 1/2 teaspoon dried thyme (optional): If you love an herby touch, dried thyme works wonders here. It adds another layer of aromatic complexity.
• 1.5 cups (about 6 ounces) shredded Gruyere cheese: Divided. Gruyere is my absolute favorite for scalloped potatoes. It melts beautifully, has a nutty, slightly sweet flavor that pairs perfectly with potatoes and cream, and browns wonderfully on top. If you can’t find Gruyere, a good quality sharp white cheddar or even a blend of Parmesan and mozzarella would be delightful substitutes.
• Pinch of cayenne pepper (optional): For a very subtle kick and warmth, a tiny pinch of cayenne can be a delightful addition to the sauce. It won’t make it spicy, just more vibrant.

Preparing the Scalloped Potatoes Foundation

1. Preheat the Oven and Prepare Your Baking Dish:

   Before you even think about slicing potatoes, let’s get the oven ready and butter our dish. I always preheat my oven to 375°F (190°C). This ensures it’s good and hot by the time our magnificent creation is ready to go in. Next, take about 1 tablespoon of your unsalted butter and generously grease a 9×13-inch baking dish. You want to make sure every nook and cranny is coated to prevent sticking and encourage that lovely golden crust on the edges of your scalloped potatoes. A ceramic or glass dish works best for even baking.

2. Slice the Potatoes Evenly:

   This is perhaps the most crucial step for perfect scalloped potatoes! Peel all your potatoes first. Once peeled, the goal is to slice them into very thin, uniform rounds, about 1/8-inch thick. If your slices are too thick, they won’t cook evenly, and you’ll end up with some crunchy bits and some mushy bits. If they’re too thin, they might disintegrate.

   My absolute favorite tool for this is a mandoline slicer. It makes quick work of the task and guarantees consistency, which is key for those perfectly tender-crisp scalloped potatoes. If you don’t have a mandoline, a very sharp chef’s knife and a steady hand will do the trick. Just take your time and focus on making each slice as identical as possible.

   Pro Tip: As you slice them, you can place them directly into a large bowl of cold water. This helps to remove some of the excess starch, which can make the finished dish gluey, and prevents them from browning. However, if you’re making your sauce immediately, you can skip the water bath and just make sure to pat them very dry before layering. I personally like to give them a quick rinse and then pat them thoroughly dry with kitchen towels before layering. This prevents the sauce from becoming overly starchy and ensures a beautifully creamy consistency for your scalloped potatoes.

Crafting the Velvety Cream Sauce

3. Sauté the Aromatics:

   In a medium saucepan or a Dutch oven, melt 2 tablespoons of the remaining unsalted butter over medium heat. Once the butter is shimmering, add your finely minced garlic and the chopped onion or shallots. Sauté gently for 3-5 minutes, stirring occasionally, until they are wonderfully fragrant and translucent. You don’t want them to brown, just to soften and release their sweet aromas. This aromatic base is essential for a truly flavorful batch of scalloped potatoes.

4. Create the Roux:

   Now, it’s time to build the foundation of our magnificent cream sauce. Sprinkle the 1/4 cup of all-purpose flour over the softened garlic and onions. Stir constantly with a whisk for about 1-2 minutes, cooking out the raw flour taste. What we’re making here is a “roux,” which will thicken our sauce beautifully. You want to cook it long enough to eliminate any raw flour taste, but not so long that it browns. We’re aiming for a pale, golden roux to keep our scalloped potatoes sauce a lovely, creamy white.

5. Whisk in the Liquids and Seasonings:

   Slowly, and I mean slowly, pour in the whole milk and heavy cream, whisking continuously. This slow addition and constant whisking are paramount to prevent lumps and create a perfectly smooth sauce. It will look thin at first, but don’t worry, it will thicken. Continue to whisk as the mixture comes to a gentle simmer. Once it starts to bubble slightly and thickens to a consistency similar to a thin gravy or warm custard, remove it from the heat.

   Now for the critical seasoning! 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 1/2 teaspoon of dried thyme (if using). If you’re using that tiny pinch of cayenne, add it now too. Taste the sauce – this is your chance to adjust the seasoning before it goes into the oven. Remember, potatoes absorb a lot of salt, so don’t be shy, but don’t overdo it either. You want it to taste well-seasoned, almost a little aggressively seasoned, on its own. This ensures your final scalloped potatoes are bursting with flavor.

Assembling the Layers of Deliciousness

6. Begin Layering the Scalloped Potatoes:

   Now for the fun part – assembling! Take your prepared baking dish. Spread about 1/2 cup of the cream sauce evenly over the bottom of the dish. This prevents the first layer of potatoes from sticking and ensures they cook beautifully.

   Next, arrange a single layer of your sliced potatoes over the sauce, slightly overlapping them. Think of it like a beautiful, edible mosaic. Try to make sure they are in an even layer so they all cook consistently.

7. Layer with Sauce and Cheese:

   Once your first potato layer is down, pour about 1 cup of the cream sauce evenly over the potatoes. Use the back of a spoon or a spatula to ensure the sauce gets into all the nooks and crannies. This is key for those lusciously moist scalloped potatoes.

   Then, sprinkle about 1/2 cup of your shredded Gruyere cheese over the sauce. The cheese will melt down into the sauce and between the potato layers, adding incredible flavor and richness.

8. Repeat the Layers:

   Continue this layering process: potatoes, then sauce, then cheese. You should aim for about 3-4 layers of potatoes, depending on the thickness of your slices and the depth of your dish. Make sure your final layer is a potato layer, topped generously with the remaining cream sauce and then all of the remaining Gruyere cheese. This top layer of cheese will become gloriously golden brown and bubbly during baking, providing a fantastic contrast in texture to the tender potatoes below. Don’t be afraid to press down gently on the layers to ensure everything is nicely packed and submerged in the sauce. This helps all the potatoes cook evenly and absorb that amazing creamy goodness.

Baking and Resting for Perfection

9. The First Bake – Covered:

   Cover the baking dish tightly with aluminum foil. This is a critical step! Baking covered creates a steamy environment that helps the potatoes cook through and become wonderfully tender without drying out or burning the top too quickly. Place the covered dish into your preheated 375°F (190°C) oven and bake for 45 minutes to 1 hour.

   How to check for doneness: After 45 minutes, carefully remove the foil and gently pierce the thickest part of the potatoes with a thin knife or a skewer. It should slide in with very little resistance. If the potatoes still feel firm, re-cover and continue baking for another 10-15 minutes, then check again. We want them fork-tender, not al dente, for truly melt-in-your-mouth scalloped potatoes.

10. The Second Bake – Uncovered:

    Once the potatoes are tender, remove the foil. Increase the oven temperature to 400°F (200°C). Return the uncovered dish to the oven and continue baking for another 20-30 minutes, or until the top is beautifully golden brown, bubbly, and irresistible. Keep an eye on it to prevent the cheese from getting too dark. If it’s browning too quickly, you can always loosely tent it with foil again for the last few minutes. This final blast of heat creates that coveted crispy, cheesy crust on top of your creamy scalloped potatoes.

11. Resting is Essential for Perfect Scalloped Potatoes:

    I know, I know, it’s hard to wait when your kitchen smells this incredible, but trust me on this! Once your scalloped potatoes are out of the oven, do not cut into them immediately. This is perhaps one of the most overlooked, yet vital, steps. Let the dish rest on a wire rack for at least 15-20 minutes before serving.

    Why is this so important? As the dish cools slightly, the sauce will continue to thicken and set. If you cut into it too soon, the sauce will be too liquid, and your beautiful layers of scalloped potatoes will collapse and become a messy (albeit delicious) puddle. The resting period allows everything to firm up, resulting in cleaner slices and a more cohesive, perfectly textured dish. This waiting period also allows the flavors to meld and deepen, making every bite even more satisfying.

12. Serve and Enjoy:

    After the resting period, your glorious scalloped potatoes are ready to be served. Use a sturdy spatula to scoop out generous portions. They are the perfect side dish for so many meals – roasted chicken, holiday ham, steak, or even as a comforting main dish with a simple green salad. Each spoonful will be a symphony of tender potatoes, rich creamy sauce, and that delightful cheesy crust. Enjoy every luxurious bite!

Think classic pairings like a succulent roasted chicken, a perfectly glazed ham, or a juicy, pan-seared steak.

For a lighter touch, consider serving them alongside grilled salmon or even a simple green salad dressed with a bright vinaigrette to cut through the richness. They are, without a doubt, a showstopper at any holiday gathering – Thanksgiving, Christmas, or Easter – making them a cherished tradition for many families. However, don’t reserve them just for special occasions; they make an incredible Sunday dinner side or even a comforting weeknight treat that feels indulgent without excessive effort.

Want to experiment with cheese?

Go for it! Gruyere will add a nutty, earthy depth, sharp cheddar brings a delightful tang, or a blend of Fontina and Parmesan can create an incredibly complex flavor profile. For an extra layer of flavor, consider adding finely chopped fresh herbs like thyme, rosemary, or chives to the cream mixture. A pinch of freshly grated nutmeg can enhance the creamy notes, while a dusting of paprika on top can add a subtle smoky flavor and a beautiful color. For those who love a bit of extra texture and richness, crispy bacon bits, caramelized onions, or even sautéed mushrooms can be folded into the layers, elevating the dish even further. You could also experiment with different types of potatoes – while Russets or Yukon Golds are my go-to for their starch content, a mix could offer interesting textural differences.
