- 1 1/2 cups heavy cream: Creates the gorgeously silky base of the sauce.
- 1/2 cup grated cheddar cheese: Brings sharpness and gooey texture.

How to Make Delmonico Potatoes Recipe
Step 1: Prepare the Oven and Baking Dish
Begin by preheating your oven to 375°F (190°C). This ensures it’s hot enough for cooking the potatoes evenly and melting the cheese into a golden crust. Don’t forget to grease your 9×13-inch baking dish to prevent sticking and make serving easier later on.
Step 2: Sauté Onion and Garlic
In a large skillet, warm the butter and olive oil over medium heat. Add the diced onion and minced garlic, sautéing them for 3 to 4 minutes until they soften and release their fragrant aroma. This step builds the flavor foundation for the creamy sauce.
Step 3: Make the Cheese Sauce
Stir in the heavy cream along with the grated cheddar and Parmesan cheeses. Season with salt and pepper to taste. Keep cooking gently until the cheeses have melted completely and the sauce thickens slightly, turning into a velvety mix ready to coat your potatoes.
Step 4: Layer the Potatoes
Arrange the sliced potatoes evenly in the prepared baking dish. Pour the warm creamy cheese sauce over the potatoes, making sure each slice is covered generously. This careful layering ensures every bite is bursting with flavor.
Step 5: Bake Covered
Cover the dish with foil to trap the steam, allowing the potatoes to cook through and soak up the sauce gently. Bake for 40 to 45 minutes until the potatoes are tender when pierced with a fork.
Step 6: Finish Baking Uncovered
Remove the foil and continue baking for an additional 10 minutes. This final step crisps up the top, giving you that irresistible golden crust that makes Delmonico Potatoes so special. Once done, garnish with freshly chopped parsley before serving.
How to Serve Delmonico Potatoes Recipe

Garnishes
Fresh parsley is a classic garnish here, adding a burst of green color and a subtle herbaceous note that cuts through the richness. For an extra touch, you can sprinkle finely chopped chives or a little smoked paprika to add depth and visual appeal.
Side Dishes
Delmonico Potatoes are incredibly versatile and shine alongside roasted meats such as chicken, steak, or pork. They also pair wonderfully with steamed vegetables or a crisp green salad to add some freshness and balance to the creamy texture.
Creative Ways to Present
For a stunning presentation, serve the potatoes in individual ramekins or small baking dishes straight from the oven. You can also layer them in a cast-iron skillet and serve family-style for a rustic feel. Drizzling some browned butter on top before the parsley garnish gives an extra nutty richness.
Make Ahead and Storage
Storing Leftovers
Let leftover Delmonico Potatoes cool completely before transferring them into an airtight container. Stored in the refrigerator, they keep well for up to 3 days, making a delicious next-day side dish or comfort food fix.
Freezing
Although freezing creamy potato dishes can sometimes affect texture, you can freeze portions of this recipe for up to 1 month. Wrap the dish tightly with plastic wrap and foil to prevent freezer burn. Thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers gently in the oven at 350°F (175°C) covered with foil to prevent drying out, for about 20 minutes or until heated through. Alternatively, microwave on medium power in shorter bursts, stirring occasionally to maintain creaminess.
FAQs
Can I use other types of potatoes for this Delmonico Potatoes Recipe?
While russet potatoes are ideal due to their texture and ability to soak up the sauce, Yukon Gold potatoes can also work well if you prefer a creamier, buttery finish.
Is it necessary to peel the potatoes?
Peeling the potatoes helps the texture stay smooth and creates a creamier bite. However, if you enjoy a bit more texture and a rustic look, you can leave the skins on after thoroughly scrubbing the potatoes.
Can I make this recipe vegetarian?
Absolutely! This recipe is already vegetarian-friendly since it uses dairy products but no meat. Just be sure to use vegetarian-friendly cheeses if that’s a concern.
What can I substitute for heavy cream?
If you want a lighter version, half-and-half or whole milk can be substituted, but the sauce will be less rich and creamy. To keep some creaminess, mixing milk with a bit of cream cheese or a roux can help maintain texture.
How thick should the potato slices be?
Slicing the potatoes about 1/8 inch thick works best for even cooking and layering. Too thick and they may take longer to bake; too thin, and they could become mushy.
Final Thoughts
Making this Delmonico Potatoes Recipe brings a little bit of classic elegance right into your kitchen with simple ingredients and straightforward steps. The creamy, cheesy layers paired with tender potatoes are truly comforting and satisfying.

- Ensure the potatoes are sliced evenly to allow uniform cooking.
- For a lighter version, substitute half-and-half for heavy cream, though the sauce will be less rich.
- Covering the dish while baking helps the potatoes cook through and retain moisture.
