Emeril's Scalloped Potatoes Recipe: Layered Crisp-Topped Magic

Emeril Lagasse’s scalloped potatoes bring comfort food to a whole new level with their golden, crisp-topped layers and rich, creamy filling. This classic dish transforms simple potatoes into a restaurant-worthy side that pairs perfectly with steak or chicken.

I’ve perfected the technique to ensure every slice delivers that satisfying crunch and velvety texture.

The secret lies in the creamy roux base—butter, flour, and milk cooked together until silky smooth—before layering thinly sliced potatoes and cheese. Emeril’s signature bold flavors shine through with garlic, herbs, and a touch of mustard for depth.

Baking at the right temperature creates that coveted crispy top while keeping the layers tender underneath.

What you’ll end up with is a foolproof, crowd-pleasing side that’s easier than it looks. The layers develop a caramelized crust while staying creamy inside, making it impossible to resist.

This recipe delivers the same flavors Emeril’s fans love, with a method that’s simple enough for weeknight dinners but impressive enough for special occasions.

Serve with a sprinkle of fresh parsley or a drizzle of hot sauce for extra flair. The possibilities for variations are endless—add bacon, swap cheeses, or adjust seasonings—but the foundation remains the same: crispy, creamy, and utterly delicious. Let’s get started!

Ingredients for emeril's scalloped potatoes

Emeril’s signature scalloped potatoes blend creamy layers with crispy tops—just nine essential ingredients transform humble potatoes into restaurant-quality comfort.

The Russet potatoes are non-negotiable—their high starch content ensures that signature crispy top. Buy a 3-pound bag from a specialty grocer like Whole Foods for optimal texture, or grab the standard russets from any supermarket. Thinly slice them at 1/8-inch thickness using a mandoline for even layers—this is critical for consistent baking. The unsalted butter should be cold when added to the roux; Plugrá or Land O’Lakes brands work best for their high-fat content. Fresh thyme and parsley elevate the dish beyond basic seasoning—Penzeys Spices carries organic bundles that stay potent longer than grocery-store jars.

No sharp cheddar? Gruyère or Fontina melts beautifully and adds nutty depth. Substituting milk? Heavy cream at half the quantity delivers richer flavor, but whole milk keeps the classic texture. The garlic and mustard are flavor anchors—skip the jarred minced garlic; fresh minced packs more punch. For a vegetarian twist, swap the cheese for nutritional yeast (though the texture will differ). Store-bought hot sauce? Crystal or Tabasco are Emeril’s go-tos for their balanced heat.

Prep the roux ahead and store it in the fridge for up to 3 days—just whisk in fresh milk when ready. The assembled dish reheats beautifully: cover with foil and bake at 350°F for 20 minutes to restore crispiness. Leftovers keep for 4 days in the fridge, but the first slice is always best. For make-ahead convenience, assemble the dish in a baking dish, refrigerate overnight, then bake straight from cold—this enhances the caramelization. Freeze portions for up to 2 months by wrapping tightly in parchment before plastic.

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

A rich, velvety cheese sauce meets crisp golden layers—here's how to execute Emeril's signature technique.

Begin by slicing the 3 lb russet potatoes into even 1/8-inch thick rounds using a mandoline or sharp knife. The consistency is critical—thinner slices yield crispy edges, while thicker ones stay too soft. Immediately place the slices in a cold water bath to prevent browning while you work.

Drain and pat the potato slices completely dry with paper towels before assembling. Wet potatoes will steam instead of crisp, defeating the entire purpose of this dish. Arrange them in a single layer on a baking sheet to ensure uniform thickness—this prevents uneven baking later.

In a medium saucepan, melt the 0.5 cup unsalted butter over medium heat until foaming. Immediately whisk in the 0.5 cup all-purpose flour to create a roux. Cook for exactly 2 minutes, stirring constantly, until the mixture turns a pale golden color—this removes the raw flour taste and builds flavor.

Gradually whisk in the 2 cups whole milk, about 1/4 cup at a time, allowing each addition to fully incorporate before adding more. Return the heat to medium and simmer for 5 minutes until the sauce thickens enough to coat the back of a spoon. Remove from heat and stir in the 2 cups sharp white cheddar cheese, minced 4 cloves garlic, 1 tbsp Dijon mustard, 0.25 cup fresh thyme leaves, 1.5 tsp diamond crystal kosher salt, and 0.5 tsp ground black pepper until completely melted and smooth.

Preheat your oven to 375°F. Grease two 8x8-inch baking dishes generously with butter—this prevents sticking and creates a crispy bottom layer. Begin layering by placing a single layer of potato slices in each dish, slightly overlapping them. Pour half of the cheese sauce over each layer, then sprinkle with about 1/3 of the remaining cheddar cheese.

Repeat with another layer of potatoes, then another half of the sauce and cheese. Finish with a final layer of potatoes, this time pressing down gently to ensure even contact with the sauce below. The top layer should be completely covered with sauce—this creates the signature crispy crust.

Bake uncovered for 45 minutes, then increase the oven temperature to 425°F. Continue baking for an additional 15-20 minutes until the top is deeply golden brown and the edges are bubbling vigorously. The cheese should be bubbling like a fondue, with a crispy crust forming on top.

Remove from the oven and let rest for 10 minutes before serving. This resting period allows the layers to set slightly, making it easier to slice. Garnish with chopped fresh parsley leaves and serve with the 1 tbsp hot sauce on the side for those who prefer extra heat.

The moment you cut into these potatoes is when the magic happens. The contrast between the crispy golden top layer and the creamy, cheesy potato interior is what makes this dish legendary. Serve family-style straight from the baking dish so everyone can experience that perfect first bite.

For best results, consume within 2 hours of baking—this dish doesn't reheat well, and the crispy top loses its texture when warmed. The flavors will only improve as it sits at room temperature, so don't rush this part of the process.

Best sauces and condiments for this recipe

Creamy Garlic Sauce

Emeril’s signature roux-based sauce is the heart of these scalloped potatoes. The butter-flour roux cooked to a pale gold creates a velvety base that perfectly coats the potatoes.

I like to add 1 tsp of lemon juice to the finished sauce just before assembling—it brightens the richness and balances the cheddar. For extra depth, toast 1 tsp of breadcrumbs in the butter before adding flour to create a nutty undertone. 🌟

Herb-Infused Cheese Sauce

Fresh herbs elevate this dish from ordinary to extraordinary. I recommend adding 1 tsp of Worcestershire sauce to the cheese sauce for an umami boost that pairs beautifully with the cheddar. For a different twist, swap the thyme for fresh rosemary—its piney aroma complements the garlic and mustard.

If you’re feeling adventurous, fold in 2 oz of cream cheese at the end for a silkier texture.

Spicy Mustard Drizzle

Emeril often finishes his scalloped potatoes with a drizzle of spicy brown mustard> mixed with a splash of milk. I use 1 tbsp of spicy mustard> whipped with 1 tsp of milk> and drizzle it over the top of the baked potatoes right before serving.
