Why Make This Delicious Recipe & When to Serve It
At its heart, this dish is the ultimate comfort food. The combination of tender potatoes, rich dairy, and savory aromatics creates a hearty, soul-satisfying experience that is universally loved. It’s the kind of side dish that often steals the show, becoming the most talked-about item on the menu.
The beauty of scalloped potatoes lies in their versatility. They are an essential part of celebratory feasts, sitting proudly alongside a Thanksgiving turkey, an Easter ham, or a Christmas roast beef. Yet, they are equally at home at a casual potluck, a special family gathering, or simply as the indulgent star of a cozy weekend meal.
Many home cooks are hesitant to tackle scalloped potatoes, fearing common pitfalls like undercooked potatoes, a watery sauce, or a broken, curdled mess. This recipe is specifically engineered to be foolproof. By gently simmering the potatoes in the cream sauce before baking, we eliminate the guesswork and guarantee tender potatoes and a stable, perfectly creamy sauce every single time, giving you the confidence to serve this impressive dish without stress.
Basic Ingredients (Serves 6-8)
The selection and ratio of these ingredients are designed to work in harmony to create the perfect texture and flavor.
- 2 ½ lbs Yukon Gold Potatoes: These waxy potatoes are the ideal choice because they contain enough starch to help thicken the sauce naturally while holding their shape beautifully during baking, preventing a mushy texture.
- 2 cups Heavy Cream: The high-fat content of heavy cream is essential for a rich, luscious sauce and, critically, it prevents the sauce from curdling or breaking under the oven's heat, ensuring a smooth finish.
- 1 ½ cups Whole Milk: Blending heavy cream with whole milk creates the perfect consistency—creamy and decadent without being overly heavy or greasy. The milk thins the sauce just enough to allow the potatoes to cook through evenly.
- 1 Shallot, thinly sliced: Shallots provide a delicate, sweet, and complex aromatic base that is less aggressive than a yellow onion, infusing the cream with a sophisticated flavor that complements the richness of the dish.
- 4 cloves Garlic, smashed: Smashing the garlic cloves allows their essential oils to infuse the cream mixture during the steeping process, providing a deep, mellow garlic flavor throughout the dish without any harsh, raw bites.
- 1 ½ tsp Kosher Salt: This specific amount is crucial for seasoning the entire dish. The sauce must taste slightly oversalted before baking, as the bland potatoes will absorb a significant amount of salt as they cook.
- 1 tsp Whole Black Peppercorns: Using whole peppercorns to infuse the cream provides a sharp, clean pepper flavor that cuts through the richness of the dairy, offering a more nuanced heat than pre-ground pepper.
- 8 oz Gruyère Cheese, shredded: Gruyère is the superior cheese for this dish due to its excellent melting properties and its nutty, slightly sweet flavor that adds incredible depth and complements the potatoes perfectly.
- 2 tbsp Unsalted Butter: Used to grease the dish and dot the top, butter adds a final layer of richness and helps the top of the potatoes achieve a beautiful, golden-brown, and crispy crust during the final stage of baking.
- 2 tbsp Fresh Chives, thinly sliced (for garnish): Added at the end, fresh chives provide a pop of color and a mild, fresh oniony bite that cuts through the creaminess and brightens the overall flavor of the finished dish.
Step-by-Step Preparation
This method is a hybrid approach, combining stovetop simmering with baking to ensure perfectly cooked potatoes and a flawless sauce. Each step is a deliberate action designed to control flavor, texture, and doneness for a predictable, successful outcome.
1. Prepare the Aromatics and Infuse the Cream: In a large saucepan, combine . the 2 cups of heavy cream, 1 ½ cups of whole milk, the sliced shallot, 4 smashed garlic cloves, and 1 tsp of whole black peppercorns. Bring the mixture to a gentle simmer over medium heat, then immediately remove from the heat, cover, and let it steep for 30 minutes. This critical step infuses the dairy with a deep, complex flavor base.
2. Preheat Oven and Prepare Potatoes: While the cream is infusing, preheat your oven to 375°F (190°C) and generously grease a 9x13-inch baking dish with part of the 2 tbsp of unsalted butter. Using a mandoline for precision, slice the 2 ½ lbs of Yukon Gold potatoes into uniform 1/8-inch thick rounds. Do not rinse the potatoes, as their surface starch is essential for thickening the sauce.
3. Strain Cream and Simmer the Potatoes: Strain the steeped cream mixture through a fine-mesh sieve into a large bowl, pressing on the solids to extract all the liquid; discard the solids. Pour the infused cream back into the saucepan, stir in the 1 ½ tsp of kosher salt, and add the sliced potatoes. Bring to a simmer over medium heat and cook, stirring gently, for 3-5 minutes until the potatoes are just barely tender but still hold their shape.
4. Assemble the First Layer: Using a slotted spoon, transfer half of the par-cooked potatoes and their associated cream sauce into the prepared baking dish, spreading them into an even layer. Sprinkle half of the 8 oz of shredded Gruyère cheese (4 oz) evenly over the potatoes. This layering technique ensures cheese is distributed throughout the entire dish, not just on top.
5. Assemble the Final Layer and Bake: Layer the remaining potatoes and cream on top, creating a final, even surface. Top with the remaining 4 oz of Gruyère cheese and dot the surface with the rest of the 2 tbsp of unsalted butter. Cover the dish tightly with aluminum foil and bake for 45 minutes. Covering with foil traps steam, ensuring the potatoes cook through evenly without the top burning.
6. Uncover and Brown for the Perfect Finish: After 45 minutes, carefully remove the foil. Continue to bake, uncovered, for another 20-30 minutes, or until the sauce is bubbly, thickened, and the top is deeply golden brown and crisp. A knife inserted into the center should meet no resistance. This final, uncovered baking stage is crucial for developing the irresistible crust.
7. Rest, Garnish, and Serve: Remove the scalloped potatoes from the oven and let them rest for at least 15-20 minutes before serving. This step is non-negotiable; it allows the sauce to cool slightly and set, preventing a watery consistency. Garnish with the 2 tbsp of fresh chives just before bringing to the table.
Tips for the Perfect Recipe
Achieving scalloped potato perfection is easy with these expert tips that focus on technique and understanding the science of the ingredients.
- Achieve Uniform Slices: A mandoline slicer is your best friend for this recipe. It ensures every potato slice is a consistent 1/8-inch thick, which is the single most important factor for even cooking. If some slices are thick and others thin, you'll end up with a mix of mushy and crunchy potatoes.
- Don't Rinse the Potatoes: After slicing, resist the urge to rinse the potatoes. The cloudy starch on their surface is a powerful natural thickener that will create a velvety, creamy sauce without the need for flour. Rinsing it away is a common cause of watery scalloped potatoes.
- Use High-Quality, Block Cheese: For the best flavor and meltability, grate your own cheese from a block. Pre-shredded cheeses are often coated with anti-caking agents like cellulose, which can result in a gritty texture and prevent the sauce from becoming perfectly smooth and emulsified.
- The Crucial Resting Period: You must let the dish rest for 15-20 minutes after it comes out of the oven. This allows the starches to set and the sauce to thicken properly as it cools slightly. Serving it piping hot and immediately will result in a runnier, less cohesive dish.
- Baking Dish Matters: Use a shallow ceramic or glass 9x13-inch baking dish. A shallow dish promotes even cooking and maximizes the surface area for that delicious, golden-brown crust. A deeper dish can lead to longer cooking times and uneven results.

Serving Ideas
While magnificent on their own, scalloped potatoes are a team player. Here are some classic and creative ways to serve them.
- Classic Holiday Pairings: This dish is the perfect partner for roasted meats like Honey-Glazed Ham, Roast Turkey Breast, or a show-stopping Beef Tenderloin. The creamy potatoes beautifully complement the savory centerpiece.
- Simple Weeknight Dinners: Elevate a simple meal by serving alongside Roast Chicken or even pan-seared pork chops. Some traditional recipes even call for baking the pork chops right on top of the potatoes for the last portion of the cooking time.
- Balancing the Richness: To cut through the decadent creaminess, pair the potatoes with a simple green salad tossed in a sharp vinaigrette or a side of steamed or roasted green beans with a squeeze of fresh lemon.
- Garnish with Flair: Beyond chives, consider a sprinkle of fresh thyme leaves to echo the flavor in the sauce, a dash of paprika for color, or even some crispy, crumbled bacon for a "loaded" scalloped potato experience.
Tips for Storing and Reheating
Follow these best practices to ensure your leftover scalloped potatoes are just as delicious the next day.
Storing Leftovers
- Cool Completely: Always allow the scalloped potatoes to cool to room temperature on the counter before covering and refrigerating. Covering them while hot traps steam, which can create condensation and make the sauce watery.
- Airtight Storage: Transfer leftovers to an airtight container or cover the original baking dish tightly with aluminum foil or plastic wrap to prevent them from drying out or absorbing other odors in the fridge.
- Refrigerate Promptly: For optimal freshness and food safety, store the cooled potatoes in the refrigerator for up to 3-4 days.
Reheating Tips
- Oven is Best: The oven is the superior method for reheating, as it helps revive the crispy top and heats the dish evenly. Place potatoes in an oven-safe dish, cover with foil, and bake at 350°F (175°C) for 20-30 minutes, or until heated through. For the best texture, remove the foil for the last 5-10 minutes to re-crisp the cheesy top.
- Add a Splash of Milk: If the potatoes seem to have absorbed most of the sauce and appear a bit dry, drizzle a tablespoon or two of milk or cream over them before reheating. This will help restore the original creaminess of the sauce.
- Microwave in a Pinch: For a quick, single serving, the microwave is an option. Place a portion on a microwave-safe plate and reheat on 50-70% power in 1-minute intervals until hot. Be aware that the texture will be softer and you will lose the crispy top.
Conclusion
Scalloped potatoes are more than just a side dish; they are a celebration of simple ingredients transformed into something truly special. With their layers of tender potato, rich and savory cream sauce, and a perfectly golden-brown top, they represent comfort food at its absolute finest. Armed with this foolproof recipe and a deeper understanding of the techniques, you are now ready to create your own delicious memories and a dish that will earn a permanent place in your culinary repertoire.
Frequently Asked Questions
Q: What is the real difference between scalloped potatoes and potatoes au gratin?
A: Traditionally, scalloped potatoes are baked in a cream sauce without cheese. Potatoes au gratin, on the other hand, includes cheese layered within and often has a cheesy or breadcrumb topping. This popular recipe is a delicious hybrid of the two styles.
Q: Can I make scalloped potatoes ahead of time?
A: Yes, you can assemble the entire dish, bake it completely, and let it cool. Store it covered in the refrigerator for up to 2 days. Reheat in a 350°F oven for 20-30 minutes until bubbly. This is a great way to save time for a big event.
Q: Why did my sauce turn out watery or curdled?
A: A watery sauce is often due to rinsing the potatoes' starch off or not letting it rest after baking. Curdling is caused by using low-fat dairy. This recipe prevents both issues by using un-rinsed starchy potatoes and full-fat heavy cream to ensure a stable, thick sauce.
Q: Can I use Russet potatoes instead of Yukon Gold?
A: You can, but the texture will be different. Russets are starchier and will create an even creamier sauce, but they are more likely to fall apart and become mushy. For the distinct, tender layers pictured here, Yukon Gold potatoes are highly recommended.
