Ingredients for flemings potatoes copycat
Five core ingredients transform into restaurant-quality cheesy pull-apart perfection with mustard-kissed crust.
| Ingredient | Amount | Notes |
|---|---|---|
| Yukon Gold Potatoes 🥔 | 3 lb | Thinly sliced, peeled, uniform thickness |
| Sharp White Cheddar Cheese 🧀 | 2 cups | Freshly grated, block preferred |
| Dijon Mustard 🍯 | ½ cup | High-quality, tangy variety |
| Heavy Cream 🥛 | ½ cup | Full-fat for optimal richness |
| Unsalted Butter 🧈 | ½ cup | Melted for sauce base |
| Garlic Cloves 🧄 | 4 cloves | Minced for mustard sauce |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
| Fresh Chives 🌱 | ⅛ cup | Chopped, for garnish |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For seasoning and sauce |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground for heat |
| All-Purpose Flour 🌾 | 2 tbsp | For dusting potato slices |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For pan-searing potatoes |
The Yukon Gold potatoes are non-negotiable—their waxy texture and creamy interior create the ideal base for this dish. Purchase them fresh from specialty grocers like Whole Foods or Trader Joe's for optimal starch content. Thinly slice them 1/8-inch thick using a mandoline for uniformity, which ensures even cooking. Prevent browning by soaking slices in cold water for 10 minutes before draining. For the sharp white cheddar, avoid pre-shredded—it contains anti-caking agents that prevent proper melting. Grate your own from a block for that authentic, gooey texture the restaurant version is known for. Penzeys or local artisanal cheese shops offer the most flavorful options.
No Dijon mustard? Substitute with a blend of yellow mustard and a pinch of white vinegar for tang. Fresh garlic is essential—jarred minced garlic lacks depth. For the heavy cream, never use light cream—the fat content is critical for that velvety sauce. Short on butter? Olive oil works in a pinch, though it alters the flavor profile slightly. Pre-shredded cheese is a no-go—it contains starch that prevents proper melting. Fresh herbs elevate the dish, but dried parsley or chives at half the amount will suffice if needed. Seasoning matters: Diamond Crystal kosher salt dissolves more easily than table salt, enhancing flavor without overpowering the delicate balance of mustard and cheese.
Store prepped potato slices in cold water in the fridge for up to 2 hours before cooking to prevent browning. The mustard sauce can be made 2 days ahead and stored in an airtight container—reheat gently before mixing with cream. Assembled casserole keeps for 3 days in the fridge, though best results come from baking fresh. Freeze unbaked portions for up to 2 months—thaw overnight before baking. Garnishes like parsley and chives should be added post-baking to preserve their vibrant color and fresh flavor. Reheat leftovers covered at 350°F for 15-20 minutes to maintain crispiness.

Step-by-step instructions for Flemings potatoes copycat recipe
Master this iconic dish with precise technique for that signature mustard-kissed crust and gooey cheddar pull-apart perfection.
Prepare the Potatoes for Maximum Crispiness
Peel the 3 lb Yukon Gold potatoes and slice them into ⅛-inch thick rounds using a mandoline or sharp knife. I find consistency is key here—thin slices ensure even cooking and that coveted crispy exterior. Immediately place the slices in a bowl of cold water to prevent browning while you work.
Drain and thoroughly pat the potato slices dry with paper towels. Any moisture left on them will steam instead of crisp, so take your time here. In a separate bowl, toss the dry potatoes with 2 tbsp all-purpose flour and 1 tsp Diamond Crystal kosher salt. This creates a light coating that helps develop that golden crust during searing.
Sear the Potatoes in Olive Oil
Heat 2 tbsp extra-virgin olive oil in a large oven-safe skillet over medium-high heat until shimmering. Add half of the potato slices in a single layer, leaving space between each piece. Cook undisturbed for 3-4 minutes until the edges begin to brown and the undersides develop a golden crust.
Flip the potatoes carefully with a spatula and cook another 2-3 minutes until the second side is also golden brown. Remove the seared potatoes to a plate and repeat with the remaining slices. The goal is to develop maximum crispiness before baking—they'll finish cooking in the oven. If your pan gets crowded, work in batches to maintain even browning.
Build the Cheesy Mustard Layer
Reduce heat to medium and add the 0.5 cup melted unsalted butter to the same skillet. Stir in the 0.5 cup Dijon mustard and cook for 1 minute until the mixture begins to bubble. Remove from heat and whisk in the 0.5 cup heavy cream until smooth and slightly thickened.
Return the skillet to medium heat and sprinkle half of the 2 cups freshly grated sharp white cheddar cheese over the potatoes. Stir gently to distribute the cheese evenly, then add the minced 4 cloves garlic. The cheese should begin to melt and create a glossy, bubbling layer. Remove from heat once the cheese is fully melted and the potatoes are coated.
Bake to Pull-Apart Perfection
Transfer the skillet to a preheated 375°F oven and bake for 20-25 minutes, until the cheese is fully melted and bubbling vigorously. The edges should be golden brown and crispy, with the center still slightly soft—this ensures that pull-apart texture. If the top browns too quickly, tent loosely with foil.
In the final 2 minutes of baking, sprinkle the remaining 1 cup cheddar cheese over the top. Watch closely as it melts and creates that signature golden crust. Remove from the oven and let rest for 5 minutes before serving—this allows the layers to set slightly and makes for easier serving.
Garnish and Serve Immediately
Transfer the potatoes to a serving platter and immediately sprinkle with the chopped 0.25 cup fresh parsley and 0.125 cup fresh chives. The fresh herbs add a bright contrast to the rich, cheesy potatoes. Serve family-style straight from the skillet for that authentic restaurant experience, with extra cheese on the side for those who want it.
Each bite should deliver crispy potato edges, creamy cheddar pull-apart texture, and that signature tangy mustard kick. The dish holds well for 20-30 minutes if needed, but it's best served immediately while the potatoes are at their peak texture and temperature.
Pro Tips For Making Flemings Potatoes Copycat
- Parboil Potatoes First: Toss peeled Yukon Golds into boiling salted water for 5 minutes before baking—this guarantees they cook through without turning gummy. I learned this the hard way when my first batch came out underdone and sad, even after an extra 30 minutes in the oven.
- Grate Cheese Fresh: Skip the pre-shredded stuff—it’s coated in anti-caking agents that make the sauce grainy. Use a box grater and pulse sharp white cheddar in a food processor for a powdery texture that melts like a dream. Yes, it takes 2 minutes, but the difference is noticeable.
- Don’t Overmix the Cream: Whisk the heavy cream and Dijon together just until combined—lumps mean a lumpy sauce. A quick pulse with a fork or immersion blender does the trick. Overmixing turns the sauce into a gluey mess that clings to the potatoes like regret.
- Bake at 375°F, Not Higher: The recipe calls for 375°F for a reason—it’s the sweet spot for creamy potatoes with a golden crust. Cranking it to 400°F burns the cheese before the potatoes finish. I know, I know, you’re eager, but trust the process.
Best sauces and condiments for these flavors
Mustard Cream Sauce
The Dijon mustard-cream sauce is the heart of this dish, balancing the richness of cheddar with tangy depth. Start by melting 0.5 cup unsalted butter in the same skillet used for searing—this carries residual potato flavor.
Whisk in 0.5 cup Dijon mustard and cook for 1 minute to develop its sharp aroma. Remove from heat and stir in 0.5 cup heavy cream until smooth. The sauce should coat the back of a spoon but remain pourable. 🍯
Garlic-Infused Cheese
Freshly minced 4 garlic cloves elevate the dish by adding aromatic complexity. Add them to the skillet just before sprinkling the cheese, allowing them to bloom for 30 seconds to release their oils.
This creates a subtle garlic undertone that complements the mustard without overpowering it. For extra depth, I sometimes toast the garlic in the butter for 1 minute before adding the mustard. 🧄
Buttery Crispy Edges
The mustard-kissed crust comes from basting the potatoes with the sauce during baking. After searing, return the potatoes to the skillet and pour the sauce over them, letting it pool at the bottom. As the dish bakes, the sauce caramelizes, creating a glossy, golden crust.
For extra crispiness, I finish with a quick broil for 1-2 minutes under the oven's broiler, watching closely to avoid burning. 🔥
Herb Finishing Touches
Fresh parsley and chives add a bright, herbaceous contrast to the rich, cheesy potatoes. Chop them finely and sprinkle just before serving to preserve their vibrant color and fresh flavor. For a restaurant-style presentation, I arrange the herbs in a circular pattern on top, mimicking Fleming's plating technique.
A pinch of freshly ground black pepper enhances the overall flavor profile. 🌿
Optional Additions
For a spicy kick, add ½ tsp cayenne pepper to the mustard sauce before mixing with cream. If you prefer a creamier texture, stir in an extra 2 tbsp heavy cream after baking.
For a nutty depth, sprinkle 2 tbsp toasted breadcrumbs on top during the final 5 minutes of baking. Each variation keeps the dish's signature pull-apart magic intact while offering new flavor dimensions. 💡

Frequently asked questions
Why do the potatoes need to be sliced so thinly?
Thin ⅛-inch slices ensure even cooking and create that signature crispy exterior while keeping the centers creamy. Uniform thickness also prevents some slices from overcooking while others stay underdone. The restaurant version relies on this precision for that perfect pull-apart texture.
Can I make this dish ahead of time?
You can prep the potato slices up to 2 hours ahead and store them in cold water. The mustard sauce can be made 2 days ahead, but assemble and bake fresh for best results. Leftover baked potatoes reheat well in a 350°F oven for 15-20 minutes to maintain crispiness.
What if I don't have a mandoline slicer?
Use a sharp chef's knife and steady hand—place the potato on its side and slice carefully. For extra control, wrap the potato in plastic wrap first. The key is consistent thickness—aim for ⅛-inch slices by stacking and slicing multiple at once.
How do I get the mustard sauce to be extra tangy?
Use high-quality Dijon mustard and add ½ tsp lemon juice or 1 tsp white vinegar to the sauce. For deeper flavor, toast 1 tsp mustard seeds in the butter before adding the mustard. The tang should balance the cheese perfectly.
Can I use a different type of cheese?
Sharp white cheddar is ideal, but you can substitute with Pepper Jack for heat or Gruyère for nuttiness. Avoid pre-shredded cheese—it contains anti-caking agents that prevent proper melting. For best results, grate your own from a block.
