Ingredients for emeril's scalloped potatoes onions
Five core ingredients transform into Emeril's legendary golden, crispy scalloped potatoes with caramelized onions.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 2 lb | Thinly sliced, peeled preferred |
| Yellow Onions 🧅 | 2 medium | Thinly sliced, caramelized |
| Heavy Cream 🥛 | 1 ½ cups | Full-fat for richness |
| Sharp Cheddar Cheese 🧀 | 1 ½ cups | Shredded, aged preferred |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for texture |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for crisp topping |
| Fresh Thyme 🌿 | ¼ tsp | Leaves only, dried substitute |
| All-Purpose Flour 🌾 | ¼ cup | For crispy topping blend |
The potatoes are everything here—Russets are non-negotiable for their fluffy texture. Grab the pre-peeled, pre-sliced bags at Whole Foods or Trader Joe's to save time, but if you're feeling fancy, peel and slice them yourself for that restaurant-quality look. The onions? Sweet yellows caramelize best, and you'll want about 2 medium—sliced paper-thin so they melt into sweetness. For the cheese, Sharp Cheddar from Wisconsin gives that tangy bite Emeril loves. If you can't find it, Parmigiano-Reggiano works too (just grate it yourself).
No heavy cream? Half-and-half plus a splash of milk keeps it creamy without breaking the bank. Short on thyme? Dried thyme at one-third the amount works, but fresh is worth the extra sprig. The butter topping is key—cold cubes create the best crisp. No butter? Olive oil works in a pinch, though it won't be quite as golden. For the flour topping, all-purpose is fine, but breadcrumbs add extra crunch if you're feeling indulgent. Pro tip: Toast the flour and butter mixture for 2 minutes before adding to the dish—trust me on this.
This reheats beautifully—just cover with foil and warm at 350°F for 15 minutes. Keeps for 4 days in the fridge, freezes for 3 months (though the topping gets softer). I always double the recipe for leftovers—perfect for meal prep. Store in an airtight container, and the flavors only get better the next day. For serving, a sprinkle of fresh thyme right before baking adds that final Emeril touch.

Step-by-step instructions for Emeril's scalloped potatoes and onions
Here's how to build layers of creamy, cheesy perfection with a golden, crispy topping.
Prepare and Caramelize the Onions
Peel and thinly slice the 2 medium yellow onions into even rounds—about ⅛-inch thick. Heat 2 tablespoons of the ½ cup unsalted butter in a large skillet over medium heat. Add the onions and cook for 20-25 minutes, stirring occasionally, until they're deeply golden and caramelized. You'll know they're ready when they smell sweet and rich, almost like candy.
Remove the onions from the skillet and set them aside. Here's the thing—proper caramelization adds deep flavor that carries through every layer of your scalloped potatoes. Don't rush this step; patience pays off in the final dish. If the onions start to brown too quickly, reduce the heat slightly to prevent burning.
Thinly Slice and Season the Potatoes
Peel the 2 lb russet potatoes and slice them into paper-thin rounds—about ⅛-inch thick. I use a mandoline for precision, but a sharp chef's knife works too if you take your time. The thinner the slices, the quicker they'll cook and the creamier the final texture.
Spread the sliced potatoes on a clean kitchen towel and sprinkle them evenly with 1 tsp of the 1.5 tsp salt, 0.25 tsp of the 0.5 tsp black pepper, and all of the 0.25 tsp fresh thyme. Toss gently to coat. This seasoning will infuse into every layer, creating a flavorful base for the rich cream and cheese mixture. Let the potatoes sit for 10 minutes while you prepare the next components.
Create the Creamy Cheese Sauce
In a medium saucepan, combine the 1.5 cups heavy cream, 1.5 cups shredded sharp cheddar cheese, 1 tsp garlic powder, and the remaining 0.5 tsp salt and 0.25 tsp black pepper. Place the saucepan over medium-low heat and stir constantly until the cheese melts completely and the mixture thickens to a velvety consistency—about 5-7 minutes.
Remove the sauce from heat and stir in the 0.25 cup all-purpose flour to create a smooth, thickened base. This flour helps bind the sauce and adds a subtle crispness that contrasts beautifully with the creamy layers. Taste and adjust seasoning if needed—you want a balance of sharp cheddar flavor, creamy richness, and just a hint of garlic warmth.
Assemble the Layers
Preheat your oven to 375°F. In a 9x13-inch baking dish, spread half of the caramelized onions evenly across the bottom. Then layer half of the potato slices on top, slightly overlapping them. Pour half of the cheese sauce over the potatoes, spreading it evenly to coat each slice. Repeat with the remaining onions, potatoes, and sauce, ending with a final layer of potatoes.
Here's where it gets good—dot the top with the remaining 3 tablespoons of the ½ cup unsalted butter, cut into small cubes. This butter will melt and create a golden, crispy crust that contrasts perfectly with the creamy layers below. Press down gently on the potatoes during the first 10 minutes of baking to help them soften evenly.
Bake to Golden Perfection
Transfer the baking dish to the preheated oven and bake for 45-50 minutes, until the top is golden brown and the edges are bubbling. The potatoes should be tender when pierced with a fork, and the cheese sauce should be thick and creamy throughout.
Let the scalloped potatoes rest for 10-15 minutes before serving—this allows the layers to set slightly and makes slicing much easier. The contrast of the crispy golden top, creamy cheese layers, and sweet caramelized onions creates a symphony of textures and flavors that's pure comfort food at its best. Serve warm with a simple green salad or crusty bread to soak up every last bit of that rich sauce.
Pro Tips For Making Emeril'S Scalloped Potatoes Onions
- PARBOIL POTATOES FIRST: I learned this the hard way—skipping the parboil means uneven cooking and a gummy mess. Slice your Russets first, then boil them whole in salted water for 5 minutes before draining. This keeps them from falling apart when layering and guarantees even tenderness.
- SAUTÉ ONIONS LOW: After burning three batches of onions, I finally figured out: low and slow is the only way. Cook your yellow onions in butter until translucent (about 8-10 minutes), not golden. Overcooking turns them bitter, and this recipe relies on their sweetness.
- LAYER CHEESE THIN: Yes, even if it looks weird, sprinkle sharp cheddar lightly between layers—about ¼ cup total. A thick blanket of cheese melts into a greasy mess instead of a creamy, flavorful topping. Save the rest for the final layer.
- COVER WITH FOIL FIRST: Start baking your scalloped potatoes uncovered for 20 minutes to let the top brown slightly. Then tent with foil for the last 20-25 minutes at 375°F. This prevents a soggy top while locking in moisture—no guesswork, just consistent results.
Wine and beer pairings for this emeril's scalloped potatoes onions
Rich Creamy Whites
Emeril’s scalloped potatoes pair beautifully with Chardonnay—specifically a buttery, oaked Chardonnay from California or Burgundy. The wine’s vanilla and caramel notes complement the caramelized onions, while its creamy body mirrors the dish’s velvety texture.
I recommend a 2019 Kendall-Jackson Grand Reserve or Louis Latour Bourgogne Blanc for that perfect balance. 🍷
Crisp Sauvignon Blancs
For a lighter option, go for a zesty Sauvignon Blanc with citrus and herbal notes to cut through the richness. A New Zealand Sauvignon Blanc like Oyster Bay or French Sancerre works wonders—its lime and green apple flavors refresh your palate between each creamy bite.
The acidity also helps cleanse the palate after the cheesy layers.
Malbec for Bold Pairings
If you prefer red wine, a medium-bodied Malbec from Argentina stands up to the dish’s richness. The plum and dark fruit notes in a Catena Zapata Malbec or Trapiche contrast beautifully with the caramelized onions, while its smooth tannins balance the creaminess.
This pairing feels surprisingly sophisticated for a comfort food dish. 🍇
Craft Beer Options
For beer lovers, a Belgian-style Witbier like Hoegaarden or Stella Artois offers a crisp, citrusy contrast. The orange peel and coriander notes in these beers brighten the dish, while their light body won’t overpower the flavors.
Alternatively, a honey-brown ale like New Belgium Fat Tire adds a touch of sweetness that pairs well with the caramelized onions.
Cocktail Pairings
For a festive touch, serve with a white wine spritzer—mix equal parts Chardonnay and sparkling water with a splash of lemon juice and a mint sprig. The effervescence and citrus cut through the richness, making it a refreshing match.
A gin and tonic with cucumber also works, especially if you add a dash of honey for sweetness. 🍹
Dessert Wine Finish
End the meal with a sweet Moscato d’Asti or Riesling—its honeyed notes complement the caramelized onions’ sweetness. The light effervescence cleanses the palate, leaving you craving another bite of those crispy, golden layers. A small glass of Vin Santo also adds a luxurious touch to the dining experience. ✨

Frequently asked questions
Can I use sweet potatoes instead of russets?
While sweet potatoes will work, they won't give you the same fluffy texture. Their natural moisture and sweetness can make the dish gummy. If you must use them, reduce the heavy cream by ¼ cup and add an extra 15 minutes to baking time. For Emeril's signature result, stick with russet potatoes—they're designed for this recipe.
Why do my scalloped potatoes turn out watery?
Watery results usually come from overcooking the onions (releasing too much moisture) or not draining the potato slices properly. Always pat sliced potatoes dry with paper towels before layering. Also, don't skip the flour in the cheese sauce—it helps thicken the mixture and prevent a runny texture. Bake until the edges bubble, not until the top is fully browned.
Can I make this dish ahead of time?
Assemble the dish up to 24 hours ahead and refrigerate uncovered. Before baking, let it sit at room temperature for 30 minutes, then bake covered with foil for the first 20 minutes to prevent a dry top. The flavors actually improve overnight as the onions continue to caramelize slightly. For best results, reheat at 350°F for 15-20 minutes.
What's the secret to that perfect crispy top?
The crispy golden crust comes from three things: cold butter cubes, toasted flour mixture, and high heat at the end. After baking for 30 minutes, increase oven temperature to 425°F for the final 10-15 minutes. This broiling step caramelizes the butter and flour for that signature crunch. Don't skip the butter—it's what creates that irresistible texture contrast.
How do I adjust this for a vegetarian main dish?
Turn this into a hearty vegetarian meal by adding a layer of sautéed mushrooms and spinach between the potato layers. For extra protein, stir ½ cup crumbled feta into the cheese sauce or top with ¼ cup toasted breadcrumbs before baking. Serve with a simple arugula salad and balsamic glaze to balance the richness. The dish becomes substantial enough to stand alone for a cozy dinner.
