Buttery layers, crispy cheese, and vinegar's tangy kiss—just 13 ingredients for Emeril's showstopper.

The potatoes need to be Russet—they hold their shape better than Yukon Gold when thinly sliced. Whole Foods or any grocery store carries them year-round, but check for firm, blemish-free tubers. The onions? Sweet yellow caramelizes best, but red works too—just be patient. For the butter, Plugrá or Land O'Lakes are reliable, but any unsalted will do. The key is keeping it cold when making the roux—don't let it turn golden or it'll taste bitter. Grab fresh thyme from the produce section—it's worth the extra dollar for that bright flavor.

No sharp cheddar? Gruyère or white cheddar work beautifully—just shred it yourself. Running low on heavy cream? Half-and-half plus a splash of milk gets you close, but the texture won't be as rich. Vinegar substitute? Apple cider vinegar at the same amount. The panko breadcrumbs can be swapped for regular breadcrumbs toasted in butter, but they won't be as crispy. For the garlic, jarred minced works in a pinch, but fresh minced gives way more flavor. The flour? King Arthur or Bob's Red Mill are my go-tos—they make the roux silky smooth.

Assemble this ahead and refrigerate for up to 24 hours—the flavors meld beautifully. Once baked, it reheats perfectly in the oven at 350°F for 15 minutes. Store leftovers covered in the fridge for 4 days, though I rarely have any. The breadcrumbs layer? Add them right before baking for maximum crisp. For extra cheese lovers, sprinkle Parmesan on top before the final 5 minutes in the oven.

Step-by-step instructions for Emeril's scalloped potatoes

Here's how to build Emeril's signature scalloped potatoes with perfectly caramelized onions and a crispy golden crust.

Peel the 2.5 lb russet potatoes and slice them into ⅛-inch thick rounds using a mandoline or sharp knife. I find the mandoline gives the most even slices, which is crucial for consistent cooking. Soak the sliced potatoes in cold water for 10 minutes to remove excess starch, then drain and pat them completely dry with paper towels.

Next, thinly slice the 1 whole yellow onions into rings. Heat 1 tablespoon of the extra-virgin olive oil in a large skillet over medium heat and cook the onions for 10-12 minutes until they're golden brown and caramelized. This step adds depth of flavor that separates good scalloped potatoes from exceptional ones. Remove the onions from the skillet and set aside, reserving the caramelized oil for later use.

In a medium saucepan, melt the 0.75 cup cold unsalted butter over medium heat. Once melted, whisk in the 0.25 cup all-purpose flour to create a roux. Cook for 2-3 minutes until the mixture turns a light golden color and smells nutty. This is your flavor foundation—don't rush this step or the sauce will taste raw.

Gradually whisk in the 1.5 cups heavy cream, stirring constantly to prevent lumps from forming. Bring the mixture to a gentle simmer and cook for 5 minutes until it thickens slightly. Remove from heat and stir in the 1 tablespoon sharp white vinegar, which brightens the flavors and balances the richness. Season with 1.5 teaspoons diamond crystal kosher salt and 0.5 teaspoon freshly ground black pepper. Finally, fold in the 2 cups shredded sharp cheddar cheese until completely melted and smooth.

Preheat your oven to 375°F. Lightly grease a 9x13-inch baking dish with the remaining olive oil. Begin by spreading half of the caramelized onions evenly across the bottom of the dish. This creates a flavorful base that will infuse into the potatoes as they cook.

Arrange a single layer of potato slices on top of the onions, slightly overlapping them. Pour half of the cheese sauce over the potatoes, making sure each slice is well coated. Sprinkle half of the 0.25 cup chopped fresh thyme leaves evenly over the sauce. Repeat with another layer of onions, potatoes, and remaining sauce, finishing with the last of the thyme. The layers should be even—this ensures consistent cooking throughout.

Cover the baking dish tightly with aluminum foil and bake for 45 minutes. This initial baking time allows the potatoes to soften and the layers to meld together without browning. After 45 minutes, remove the foil and increase the oven temperature to 425°F. This higher heat will create that coveted crispy top.

Bake uncovered for an additional 15-20 minutes until the top is golden brown and the potatoes are tender when pierced with a fork. If the top browns too quickly, tent it loosely with foil to prevent burning while still achieving that crispy texture. The potatoes are done when they're fork-tender and the sauce has thickened to a creamy consistency.

In a small bowl, combine the 0.25 cup panko breadcrumbs with the 2 minced garlic cloves. Drizzle with 1 teaspoon of olive oil and toss to coat evenly. Spread this mixture evenly over the top of the scalloped potatoes, pressing down gently to help it adhere. Return to the oven for 3-5 minutes until the topping is golden brown and crispy.

Remove from the oven and let rest for 10 minutes before serving. This resting period allows the layers to set and makes it easier to slice. The result should be tender, creamy potatoes with a crispy golden crust and caramelized onions throughout. Serve immediately while still warm for the ultimate experience.

Pro cooking tips for this dish

Layering Like a Pro

Emeril’s secret to perfect scalloped potatoes is even layering—this ensures every bite has the right balance of creamy sauce and crispy top. Start with a thin layer of caramelized onions on the bottom of your 9x13-inch baking dish to infuse flavor into the potatoes.

Use a mandoline for uniform ⅛-inch slices—thicker slices take longer to cook, while thinner ones can dry out. I overlap the potato slices slightly to prevent gaps, but don’t crowd them or they’ll steam instead of bake. 🥔

Roux Perfection

The roux is where the magic happens—this is your flavor anchor. Melt 0.75 cup cold unsalted butter over medium heat, then whisk in 0.25 cup flour and cook for exactly 2-3 minutes until it turns a light golden color.

If you rush this step, the sauce will taste raw and floury. The goal is a nutty aroma, not a dark brown color. This roux forms the base for your creamy sauce, so take your time here. 🌾

Vinegar’s Bright Touch

Don’t skip the 1 tablespoon sharp white vinegar—it’s the secret to balancing the richness of the cream and cheese. Stir it into the sauce off the heat to brighten the flavors without adding acidity.

I like to use apple cider vinegar if white vinegar isn’t available, but stick to the same amount. This small addition cuts through the fat, making each bite more dynamic. 🍶

Two-Stage Baking

Bake the potatoes covered with foil at 375°F for 45 minutes to soften them evenly. Then, crank the heat to 425°F and bake uncovered for 15-20 minutes to create that golden, crispy crust.

This two-stage approach prevents the top from browning too quickly while ensuring the potatoes cook through. If the top browns too fast, loosely tent it with foil to slow the process. 🔥

Crispy Topping Hack

For the ultimate texture, mix 0.25 cup panko breadcrumbs with 2 minced garlic cloves and 1 teaspoon olive oil before sprinkling on top. Panko stays crispy because of its light, airy structure—regular breadcrumbs will get soggy.

Press the mixture gently into the sauce so it sticks, then bake for 3-5 minutes until golden. This adds a satisfying crunch that contrasts beautifully with the creamy layers below. 🍞

Rest Before Serving

Let the scalloped potatoes rest for 10 minutes after baking—this allows the layers to set and makes slicing easier. The sauce will thicken slightly, and the potatoes will firm up just enough to hold their shape.

Skipping this step can lead to a runny mess when you cut into it. Serve warm with a sprinkle of fresh thyme or crispy breadcrumbs for extra flair. ✨
