Delmonico Potatoes Recipe – Creamy Cheese Potato Casserole

These creamy, luxurious Delmonico potatoes have been a staple in my recipe collection for years. Named after the famous New York restaurant, this rich casserole combines tender potatoes with a velvety cheese sauce that makes any meal feel special. Whether you’re hosting Sunday dinner or need an elegant side dish, this recipe delivers comfort and sophistication in equal measure.

Why This Delmonico Potatoes Recipe Works

The secret lies in the technique—partially cooking the potatoes first ensures they’re tender throughout, while the cheese sauce creates that signature creamy texture. I’ve refined this method over countless family dinners, and the result is consistently smooth, flavorful potatoes that hold their shape beautifully without becoming mushy or dry.

Ingredients

• 3 pounds Yukon Gold potatoes, peeled and cut into 1/2-inch thick slices
• 4 tablespoons unsalted butter
• 1/4 cup all-purpose flour
• 2 cups whole milk, warmed
• 1 cup heavy cream
• 1 1/2 cups sharp cheddar cheese, freshly grated
• 1/2 cup Parmesan cheese, freshly grated
• 1 teaspoon salt
• 1/2 teaspoon white pepper
• 1/4 teaspoon nutmeg, freshly grated
• 2 tablespoons fresh chives, finely chopped
• 1/4 cup panko breadcrumbs
• 2 tablespoons butter, melted for topping

The quality of your ingredients makes a significant difference in this dish, so I always use freshly grated cheese and real butter rather than substitutes.

How to Make It

1. Preheat your oven to 350°F and generously butter a 9×13-inch baking dish. Fill a large pot with salted water and bring it to a boil over high heat.
2. Add the sliced potatoes to the boiling water and cook for 8-10 minutes, until they’re just beginning to become tender but still hold their shape when pierced with a fork. You don’t want them fully cooked at this stage since they’ll continue cooking in the oven.
3. Drain the potatoes thoroughly in a colander and set them aside to cool slightly. This partial cooking step is crucial—it ensures the potatoes will be perfectly tender in the final dish without becoming waterlogged.
4. In a large, heavy-bottomed saucepan, melt the 4 tablespoons of butter over medium heat. Once melted and foaming, whisk in the flour and cook for 2-3 minutes, stirring constantly to create a light roux. This cooking time eliminates the raw flour taste.
5. Gradually add the warmed milk, whisking constantly to prevent lumps from forming. I find it helpful to add the milk in three additions, whisking smooth between each addition. The mixture should be completely smooth before adding more liquid.
6. Add the heavy cream and continue whisking. Bring the mixture to a gentle simmer and cook for 5-7 minutes, stirring frequently, until it thickens enough to coat the back of a spoon. The sauce should have a consistency similar to heavy cream.
7. Remove the saucepan from heat and immediately add the grated cheddar and Parmesan cheeses, whisking until completely melted and smooth. The residual heat will melt the cheese perfectly without risking a grainy texture.
8. Season the cheese sauce with salt, white pepper, and nutmeg. Taste and adjust seasoning as needed—the sauce should be well-seasoned since it needs to flavor the entire dish.
9. Layer half of the partially cooked potatoes in your prepared baking dish, overlapping them slightly in an even layer. Pour half of the cheese sauce over the potatoes, making sure it flows between the layers.
10. Add the remaining potatoes in another overlapping layer, then pour the rest of the cheese sauce over the top, ensuring even coverage. Gently shake the dish to help the sauce settle between the potato layers.
11. In a small bowl, combine the panko breadcrumbs with the melted butter and stir until the crumbs are evenly coated. Sprinkle this mixture over the top of the potatoes for a golden, crispy finish.
12. Cover the dish with aluminum foil and bake for 35 minutes. Remove the foil and continue baking for 15-20 minutes more, until the top is golden brown and the sauce is bubbling around the edges.
13. Remove from the oven and let rest for 10 minutes before serving. Sprinkle with fresh chives just before serving for a pop of color and fresh flavor.

This method ensures creamy, tender potatoes with a beautifully golden top that’s become the hallmark of this dish in my kitchen.

Common Mistakes

• Overcooking the potatoes in the initial boiling step, leading to mushy results
• Adding cold milk to the roux, which creates lumps that are difficult to smooth out
• Using pre-shredded cheese, which doesn’t melt as smoothly as freshly grated
• Seasoning the dish inadequately, resulting in bland flavors
• Baking at too high a temperature, causing the top to brown before the interior is heated through
• Skipping the resting period, which makes the dish difficult to serve neatly
• Not buttering the baking dish properly, leading to sticking issues
• Cutting potato slices too thick, preventing even cooking
• Adding the cheese to sauce that’s too hot, causing it to become grainy

I’ve made most of these mistakes myself over the years, and learning to avoid them has made this recipe much more reliable and delicious.

Storage and Reheating

• Store leftovers covered in the refrigerator for up to 4 days
• Reheat individual portions in the microwave at 50% power to prevent separating
• For larger portions, reheat covered in a 325°F oven for 20-25 minutes
• Add a splash of milk if the mixture seems too thick after storage
• Can be assembled a day ahead and refrigerated before baking
• Freezes well for up to 3 months when properly wrapped
• Thaw frozen portions overnight in the refrigerator before reheating
• Avoid reheating multiple times as this affects texture quality

The make-ahead capability makes this dish particularly valuable for entertaining, as most of the work can be done in advance.

Leftover Ideas
