Ingredients You’ll Need
One of the joys of this Delmonico Potatoes Recipe is how it transforms humble ingredients into something extraordinary. Each component is essential, coming together to create creamy potatoes with just the right amount of richness, tang, and crunch.
- Russet potatoes: Their fluffy texture soaks up the cheesy sauce, making every bite divine.
- Unsalted butter: Melts into the flour to make the roux and adds depth to the flavor.
- All-purpose flour: Thickens the sauce until it’s velvety and perfectly coats the potatoes.
- Whole milk: The foundation of the sauce; keeps it creamy without being too heavy.
- Heavy cream: Adds a luxurious richness that makes this dish feel special.
- Garlic powder: Brings subtle warmth and savory depth to the sauce.
- Onion powder: Enhances the potatoes with a mild, sweet onion flavor.

- Shredded sharp cheddar cheese: Delivers classic cheesy flavor and gorgeous color.
- Grated Parmesan cheese: Brings nutty complexity and a savory bite to the sauce.

- Melted butter (for topping): Ensures those breadcrumbs crisp up perfectly and add another layer of goodness.
How to Make Delmonico Potatoes Recipe
Step 1: Prep the Potatoes
Start by peeling and dicing your russet potatoes into even pieces; this helps them cook uniformly and ensures silky consistency in every bite. Boil the potatoes in salted water for about 5 to 7 minutes—just until they’re barely tender, not fully soft. Drain them promptly and set aside, as overcooking here can lead to mushy potatoes in your final Delmonico Potatoes Recipe.
Step 2: Make the Creamy Cheese Sauce
In a saucepan, melt your butter over medium heat, then whisk in the flour to create a classic roux—this is what thickens your luscious cheese sauce. Let it bubble gently for a minute or two to cook out the raw flour taste. Gradually pour in the whole milk and heavy cream, whisking constantly until the mixture is smooth and beginning to thicken, about 4 to 5 minutes. Once you have a silky base, stir in the garlic powder, onion powder, salt, and pepper, then remove the pan from the heat and whisk in the shredded cheddar and Parmesan cheeses until the sauce is gorgeously smooth and melty.
Step 3: Combine and Transfer to Baking Dish
Fold your just-cooked potatoes into the cheese sauce, making sure every potato cube is soaked in that cheesy magnificence. Pour this heavenly mixture into a greased 9×13-inch baking dish, spreading it out into an even layer so the top bakes up golden.
Step 4: Add the Crunchy Topping
This step is optional, but highly recommended for every Delmonico Potatoes Recipe. If you’re on team crunchy, stir together your seasoned breadcrumbs with melted butter, then sprinkle generously over the surface of the potato mixture. This crumbly layer bakes up crisp and adds irresistible texture to every portion.
Step 5: Bake to Perfection
Pop your assembled casserole into a preheated 375°F (190°C) oven and let it bake uncovered for 25 to 30 minutes. You’ll know it’s ready when the top is deeply golden, the sauce is bubbling around the edges, and your kitchen smells extraordinary. Rest for 5 minutes before serving, allowing the sauce to set up beautifully for perfect slices.
How to Serve Delmonico Potatoes Recipe
Garnishes
After baking, a shower of fresh chopped parsley or chives brings brightness and color to this indulgent side. You can also sprinkle a little extra Parmesan or cracked black pepper right before serving for that finishing touch that makes your Delmonico Potatoes Recipe truly special.
Side Dishes
These potatoes shine alongside classic mains like roast chicken, grilled steaks, or honey-glazed ham. For a hearty vegetarian dinner, pair your Delmonico Potatoes Recipe with roasted veggies and a fresh green salad. No matter what, they’ll take center stage!
Creative Ways to Present
If you’re serving a crowd, portion the potatoes into individual ramekins for a charming touch. For potlucks or holiday buffets, scoop the casserole into a serving platter and scatter with extra herbs—your guests will be drawn right in. You can even top with crispy bacon bits or caramelized onions to switch up the flavor and add extra flair.
Make Ahead and Storage
Storing Leftovers
Leftovers from this Delmonico Potatoes Recipe never last long! Cool any uneaten portions to room temperature, then cover tightly and refrigerate. They’ll stay creamy and delicious for up to 4 days, making for fantastic next-day lunches or sides.
Freezing
You can absolutely freeze this dish if you want to get a head start on entertaining. Once baked and cooled, wrap portions securely with foil and plastic wrap, then freeze for up to 2 months. Thaw overnight in the refrigerator for best results—the sauce may separate just a bit, but a gentle stir after reheating makes it good as new.
Reheating
To reheat, pop your leftovers (covered with foil) in a 350°F oven until warmed through—usually 15 to 20 minutes. For individual servings, the microwave works in a pinch, but the oven keeps the topping crisp. Add an extra sprinkle of cheese or a drizzle of cream before reheating to refresh the dish’s velvety texture.
FAQs
Can I use other types of potatoes in the Delmonico Potatoes Recipe?
Yes, you can substitute Yukon Gold potatoes for an even creamier bite, or red potatoes for a little more structure. Just keep in mind that russets deliver that classic, fluffy texture.
Do I need to peel the potatoes?
Peeling is recommended for the silkiest result, but if you like a rustic presentation and extra fiber, feel free to leave the skins on—they’ll add a bit of earthiness to your Delmonico Potatoes Recipe.
Is it possible to make this dish gluten-free?
Absolutely! Swap the all-purpose flour for your favorite gluten-free 1:1 baking blend and use gluten-free breadcrumbs, if you’re adding the topping. The results are every bit as delicious.
Can I prep Delmonico Potatoes Recipe in advance?
Definitely. Assemble everything except the breadcrumb topping and refrigerate overnight. Add the topping just before baking and enjoy fresh-from-the-oven flavor and texture with zero last-minute fuss.
How do I make this dish even more flavorful?
For an extra-savory boost, stir in crumbled cooked bacon, sautéed onions, or a pinch of smoked paprika into the cheese sauce. This Delmonico Potatoes Recipe is wonderfully adaptable!
