Ingredients You’ll Need
Getting the ingredients right is what makes this Delmonico Potatoes Recipe so special. Each component is simple but carefully chosen to contribute vibrant flavors, smooth texture, and that rich, comforting feel that makes every bite memorable.
- Russet potatoes: Starchy and perfect for baking, these give you tender slices with just the right structure.
- Butter: Adds richness and helps create a silky sauté base with the onions and garlic.
- Olive oil: Enhances the butter’s flavor while preventing it from burning during cooking.
- Onion: Provides a gentle sweetness and depth of flavor when sautéed.
- Garlic: Brings a lovely aromatic punch that elevates the creamy sauce.
- Heavy cream: The key to that luscious, velvety texture coating each potato slice.
- Cheddar cheese: Adds sharpness and gooey meltiness to the sauce.
- Parmesan cheese: Offers a nutty flavor and helps thicken the sauce beautifully.
- Salt and pepper: Essential seasoning to bring out the flavors.
- Fresh parsley: For a burst of color and freshness as a final garnish.
How to Make Delmonico Potatoes Recipe
Step 1: Prep and Sauté Aromatics
Start by preheating your oven to 375°F (190°C) and greasing a 9×13-inch baking dish to prevent sticking. In a large skillet, melt the butter together with olive oil over medium heat. Add the diced onion and minced garlic, then sauté for about 3 to 4 minutes until they become soft and fragrant. This step creates a wonderful base of flavor that will infuse your creamy sauce.
Step 2: Make the Creamy Cheese Sauce
To your softened onions and garlic, stir in the heavy cream along with grated cheddar and Parmesan cheeses. Season with salt and pepper to taste. Stir continuously over medium heat until the cheeses melt completely and the sauce thickens slightly. This rich and cheesy mixture is what makes this Delmonico Potatoes Recipe stand out with its irresistible creaminess.
Step 3: Layer the Potatoes
Peel and slice your russet potatoes into even slices, then layer them neatly in the greased baking dish. Pour the creamy cheese sauce evenly over the potato layers, making sure the sauce seeps into every nook and cranny to coat the slices fully. This layering is key to achieving the perfect balance of flavors in every bite.
Step 4: Bake to Perfection
Cover the dish tightly with foil and bake in the preheated oven for 40 to 45 minutes. This gentle cooking allows the potatoes to soften and absorb all that wonderful cheese sauce. Afterward, remove the foil and bake uncovered for an additional 10 minutes to let the top develop a gorgeous golden brown crust that adds wonderful texture and visual appeal.
Step 5: Garnish and Serve
Once baked, sprinkle fresh chopped parsley over the top for a pop of vibrant color and fresh flavor. Serve the Delmonico Potatoes Recipe warm for the ultimate comfort food experience that feels both homey and special.
How to Serve Delmonico Potatoes Recipe
Garnishes
Garnishing with fresh parsley is not just for looks; it adds a bright, slightly peppery freshness that balances the rich, creamy sauce perfectly. You can also sprinkle a little extra Parmesan cheese or a pinch of smoked paprika for a subtle hint of smoky warmth.
Side Dishes
This dish pairs beautifully with hearty mains like roast chicken, grilled steak, or even a juicy pork chop. The creamy richness of the potatoes complements savory meats and adds a delightful contrast to crisp green salads or roasted vegetables, making it a versatile companion for many meals.
Creative Ways to Present
For a more elegant presentation, bake the potatoes in individual ramekins and serve them as personalized side dishes. Or layer them thinly in a gratin-style spiral for a stunning visual effect. Add a drizzle of truffle oil or sprinkle crispy fried onions on top for a fancy twist that will impress your guests.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store them in an airtight container in the refrigerator for up to 3 days. The flavors develop even more after sitting, making the next meal just as delicious as the first.
Freezing
Delmonico Potatoes Recipe can be frozen, but it’s best to freeze before baking to maintain texture. Layer the potatoes and sauce in a freezer-safe container, cover tightly, and freeze for up to 2 months. When ready, bake straight from frozen, adding extra baking time as needed.
Reheating
To reheat, cover the dish loosely with foil and warm in a 350°F (175°C) oven until heated through, about 20-25 minutes. This method keeps the potatoes moist while warming them evenly. Avoid microwaving, as it can make the texture a bit soggy.
FAQs
Can I use different types of potatoes for this recipe?
While russet potatoes are ideal for their starchy texture, you can experiment with Yukon Golds for a creamier, buttery taste. Just be mindful that waxy potatoes might not soften as well during baking.
Is it possible to make this recipe dairy-free?
You can substitute the butter with a plant-based alternative and use coconut cream or cashew cream instead of heavy cream. For cheese, choose dairy-free vegan cheeses that melt well to keep the dish creamy and flavorful.
How thin should the potato slices be?
Slice the potatoes about 1/8 inch thick to ensure they cook evenly and become tender without falling apart. Uniform thickness helps the layers bake uniformly in the creamy sauce.
Can I add other herbs or spices?
Absolutely! Fresh thyme or rosemary blend beautifully with the cream and cheese, adding aromatic complexity. A pinch of nutmeg in the sauce also enhances its warmth and depth.
How long does this dish stay good after baking?
Once baked, the potatoes are best enjoyed within a few hours, but they keep well in the fridge for up to 3 days if stored properly in an airtight container.
Final Thoughts
This Delmonico Potatoes Recipe is pure comfort on a plate and has become one of my cherished dishes for sharing with friends and family.

- 1/2 cup grated Parmesan cheese
- Salt and pepper to taste
Garnish
- Fresh parsley for garnish
Instructions
- Preheat Oven: Preheat the oven to 375°F (190°C) and grease a 9×13-inch baking dish to prevent sticking and ensure even cooking.
- Sauté Aromatics: Heat butter and olive oil in a large skillet over medium heat. Add diced onions and minced garlic; sauté for 3-4 minutes until they become soft and fragrant, building the base flavor for the sauce.

Notes
- For a richer flavor, you can substitute half-and-half for some of the heavy cream.
