Ingredients for emeril's scalloped potatoes onions
Emeril's signature crispy-cornmeal-topped scalloped potatoes demand quality ingredients for that legendary restaurant texture.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lb | Thinly sliced, peeled |
| Yellow Onions 🧅 | 2 large | Thinly sliced, caramelized |
| Heavy Cream 🥛 | 2 cups | Full-fat for richness |
| Sharp White Cheddar Cheese 🧀 | 2 cups | Shredded, aged 6+ months |
| Cornmeal 🌽 | ½ cup | Fine grind preferred |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for layering |
| Garlic Powder 🧄 | 2 tsp | Freshly ground preferred |
| Dried Thyme 🌿 | 1 tsp | Or 1 tbsp fresh thyme |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Cayenne Pepper 🔥 | ¼ tsp | Adjust for heat preference |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For seasoning |
| Smoked Paprika 🌶️ | ½ tsp | For cornmeal topping |

The potatoes are non-negotiable—Russet delivers the perfect starch-to-moisture ratio for that crispy crust. Whole Foods or local farms often carry the best starchy varieties, but any russet will work. Thinly slice them with a mandoline for even layers (safety first—use the guard!). The onions? Sweet yellows like Vidalia caramelize beautifully, but yellow or red will do. Caramelize them separately before layering to deepen their sweetness—this is where Emeril's magic happens. For the cheese, aged sharp white cheddar melts smoothly without clumping; Cabot or Tillamook are my go-tos, but any aged cheddar works.
No heavy cream? Half-and-half plus a splash of milk keeps the richness. Substituting cheddar? Gruyère or Swiss add nutty depth, but cheddar's tang is traditional. The cornmeal topping needs to be fine—Bob's Red Mill is my standard, but any fine grind works. For the spices, Penzeys sells premium dried thyme, but the grocery store stuff is fine if it's recent. Want extra smokiness? Swap half the paprika for chipotle powder. The butter must be cold when layering—press cubed pieces between potato layers for maximum flavor infusion.
This dish reheats beautifully—just 350°F for 15-20 minutes covered with foil. Store leftovers in an airtight container for 4-5 days, though I rarely make it that long. For make-ahead prep, assemble the dish (without baking) and refrigerate overnight. The flavors meld beautifully, and it bakes straight from the fridge. The cornmeal topping can be pre-mixed and stored in a sealed container for 1 month—just add it fresh before baking for maximum crispiness.

Step-by-step instructions for Emeril's scalloped potatoes with onions
Master the perfect balance of crispy cornmeal crowns and creamy layers with this refined technique.
Prepare and Layer the Potatoes and Onions
Begin by preheating your oven to 375°F. Peel the 3 lb russet potatoes and slice them into ¼-inch thick rounds using a mandoline or sharp knife for even thickness. Soak the slices in cold water for 10 minutes to remove excess starch, then drain and pat completely dry with paper towels.
In a large skillet, melt 0.25 cup unsalted butter over medium heat and caramelize the 2 large yellow onions for 15-20 minutes until golden brown. Season the potatoes with 1 tsp garlic powder, 0.5 tsp ground black pepper, and 0.25 tsp cayenne pepper, then layer half of them in a 9x13-inch baking dish. Top with half the caramelized onions, then sprinkle with 1 cup sharp white cheddar cheese. Repeat with remaining layers, ending with cheese on top.
Create the Creamy Base and First Cornmeal Layer
In a bowl, whisk together the 2 cups heavy cream, 1 tsp dried thyme, and 1.5 tsp diamond crystal kosher salt until smooth. Pour half of this mixture evenly over the layered potatoes, gently tilting the dish to distribute. In a separate bowl, mix 0.25 cup cornmeal with 0.5 tsp smoked paprika and 0.25 tsp cayenne pepper, then sprinkle half of this mixture evenly over the cream.
Dot the surface with 0.25 cup cubed unsalted butter (reserve the remaining 0.5 cup butter for later). This butter will melt into the cream, creating a luxurious richness. The cornmeal layer will form a crispy crown as it bakes, while the cream ensures each layer remains velvety smooth.
Bake Until Golden and Bubbly
Transfer the baking dish to the preheated oven and bake for 45 minutes. The potatoes should be tender when pierced with a knife, and the top layer should be golden brown with visible bubbles. If the top isn't crispy enough after 45 minutes, broil for 2-3 minutes on high, watching closely to avoid burning.
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 cleanly. The contrast between the crispy cornmeal crown and the creamy, cheesy layers should be striking—each bite delivers both textures in perfect harmony.
Garnish and Serve with Fresh Herbs
Before serving, sprinkle the 0.25 cup fresh thyme leaves evenly over the top for a bright, aromatic finish. The thyme adds a fresh contrast to the rich, caramelized flavors. Serve immediately while the potatoes are still warm, ensuring the crispy crown holds its texture.
For an elevated presentation, garnish with additional caramelized onions or a drizzle of reduced cream. The dish pairs beautifully with grilled meats or a simple green salad, making it a versatile centerpiece for any meal. The key to success lies in the precise layering and the balance of crispy, creamy, and savory elements—each component must work together to deliver Emeril's signature comfort with refined technique.
Pro Tips For Making Emeril'S Scalloped Potatoes Onions
- PRECOOK THE ONIONS: Slice those yellow onions thin—like, paper-thin—and sauté them in butter until they’re golden and just starting to caramelize before layering. I learned this the hard way: raw onions in the casserole turn mushy and watery, stealing all the cream’s richness. Do this step first, or regret it later.
- SALT THE POTATOES: Toss your sliced Russets with salt before baking—about ½ teaspoon per pound—and let them sit for 10 minutes. This draws out moisture so they crisp up better in the oven. Skimping here means soggy bottom layers, and nobody wants that.
- DON’T SKIMP ON CORNMEAL: The cornmeal isn’t just for texture—it’s the crust. Mix it thoroughly with the cheese and cream, then sprinkle it generously on the very top of the final layer. Yes, it looks like overkill, but it’s what makes Emeril’s version golden and crunchy. Trust the process.
- BAKE LOW AND SLOW: Start at 375°F for the first 30 minutes, then drop to 350°F. I used to blast it at 400°F, and the top would burn before the center cooked. The lower temp ensures the cheese melts smoothly and the potatoes get tender without turning to glue. Patience pays off here.
Flavor customization for this emeril's scalloped potatoes onions
Spicy Kick Boost
If you love heat, add ½ tsp smoked cayenne to the cream sauce for a smoky, fiery depth. For extra spice, fold in 1 tbsp chipotle jam with the heavy cream—this adds both heat and smoky complexity.
I find 2-3 dashes of hot sauce (like Crystal or Tabasco) at the end of cooking also works beautifully. 🔥
Creamy Cheese Variations
Swap the sharp white cheddar for Gruyère (adds nutty richness) or fontina (creamy melt). For a tangy twist, mix in ½ cup crumbled blue cheese with the cheddar.
I also love goat cheese crumbles for a lighter option that still delivers big flavor. Each cheese changes the texture and depth of the dish.
Herb Infusions
Fresh herbs elevate this dish instantly. Try 1 tbsp chopped rosemary mixed into the caramelized onions for an earthy aroma. For brightness, add 1 tbsp chopped chives or green onions to the cream sauce.
I also like a sprinkle of fresh parsley on top before baking—it adds a fresh contrast to the rich, caramelized flavors.
Smoky Depth Additions
For a smoky profile, stir ½ tsp liquid smoke into the cream sauce or sprinkle ½ tsp smoked sea salt over the cornmeal topping. I also love adding 2 slices cooked bacon, crumbled, between layers for a salty, smoky crunch.
This works especially well if you're serving it with a hearty meat dish.
Sweet Onion Twist
Caramelize 1 small sweet onion (like Vidalia) with 1 tbsp brown sugar and 1 tsp apple cider vinegar for a sweeter, tangier flavor. This balances the richness of the cream sauce beautifully. I also like adding ½ cup dried cranberries between layers for a festive touch during holiday meals.
Extra Crispy Top
For an ultra-crispy crown, mix ¼ cup panko breadcrumbs with the cornmeal topping. Toast the panko in a dry skillet for 2 minutes before mixing to enhance its crunch. Another trick? Brush the baked dish with 1 tbsp melted butter right before serving—this adds golden shine and extra richness. ✨

Frequently asked questions
Can I use sweet potatoes instead of russets?
While russet potatoes are ideal for their starchy texture, you can substitute sweet potatoes—but expect a different texture. Sweet potatoes will be denser and less crispy on top. For best results, slice them slightly thinner (⅛-inch) and bake for 30-40 minutes at 375°F to ensure tenderness. The caramelized onions will still shine, but the dish will have a sweeter profile.
Why did my cornmeal topping get soggy?
Soggy topping usually means steam got trapped underneath. To fix this, ensure your cornmeal layer is evenly spread and not too thick (just ¼ cup total). Also, bake at 375°F for the full 45 minutes—don’t open the oven early to check! If it’s still soft, broil for 2-3 minutes at the end for extra crispiness.
Can I make this dish ahead of time?
Assemble the dish (up to the cornmeal topping) and refrigerate it overnight. When ready to bake, add the cornmeal layer and bake as directed. The flavors meld beautifully, and the potatoes will still achieve that perfect crispy top. For make-ahead reheating, cover with foil and warm at 350°F for 15-20 minutes.
What’s the secret to caramelizing the onions perfectly?
Low and slow is key! Cook the onions in 0.25 cup butter over medium-low heat for 15-20 minutes, stirring occasionally. They’re done when deeply golden and sweet—almost jammy. Avoid rushing, or they’ll burn. For extra depth, add a pinch of sugar or a splash of balsamic vinegar during cooking.
How do I adjust the spice level?
Start with the 0.25 tsp cayenne as written, but you can easily tweak it. For mild heat, reduce to ¼ tsp or omit entirely. For extra kick, add ½ tsp smoked paprika** to the cornmeal topping or a dash of hot sauce to the cream. If using chipotle jam, start with ½ tbsp and adjust to taste.
