How to Make Delmonico Potatoes Recipe
Step 1: Prepare Your Oven and Baking Dish
Start by preheating your oven to 375°F (190°C). Grease a 9×13-inch baking dish thoroughly to prevent sticking and help the potatoes brown nicely on the edges. This sets the stage for a perfectly cooked casserole with a beautiful crust.
Step 2: Sauté the Aromatics
Heat butter and olive oil in a large skillet over medium heat. Add diced onions and minced garlic, sautéing them gently for 3 to 4 minutes until they become soft and fragrant. This step infuses the dish with that classic savory flavor that will blend seamlessly with the creamy sauce.
Step 3: Create the Creamy Cheese Sauce
Once the onions and garlic are softened, stir in the heavy cream along with cheddar and Parmesan cheeses. Season with salt and pepper, then cook the mixture gently until the cheese melts and the sauce thickens, becoming luxuriously smooth and ready to coat every potato slice perfectly.
Step 4: Layer the Potatoes
Carefully arrange the peeled and sliced russet potatoes in the prepared baking dish. Make sure the slices overlap slightly for even cooking and delightful layers. Pour the rich, cheesy cream sauce evenly over the potatoes so that every slice is enveloped in flavor.
Step 5: Bake to Perfection
Cover the baking dish with foil and bake for 40 to 45 minutes, or until the potatoes are tender when pierced with a fork. Remove the foil and bake for an additional 10 minutes to give the top a gorgeous golden brown crust that adds delightful texture to the creamy inside.
Step 6: Garnish and Serve
Once out of the oven, sprinkle freshly chopped parsley over the top for a burst of color and a fresh note that balances the richness. Serve your Delmonico Potatoes warm, inviting everyone to dive into this dreamy, cheesy creation right away.
How to Serve Delmonico Potatoes Recipe

Garnishes
Fresh parsley is the classic choice to brighten the deep creaminess of Delmonico potatoes, but you can also experiment with finely chopped chives or a sprinkle of smoked paprika for an extra hint of flavor and visual appeal. A little goes a long way in elevating the presentation and taste.
Side Dishes
Delmonico Potatoes pair wonderfully with a wide range of main dishes—from juicy roasted chicken breasts to grilled steaks or even baked fish. Their creamy texture offers a lovely contrast to crisp greens or roasted vegetables, so consider serving alongside a crisp arugula salad or sautéed green beans.
Creative Ways to Present
For an elegant twist, try baking individual servings in ramekins, perfect for holiday dinners or intimate gatherings. Alternatively, use the potatoes as a base layer for a casserole topped with cooked bacon bits, caramelized onions, or even a fried egg for brunch-style indulgence. These variations keep the Delmonico Potatoes Recipe exciting every time you make it.
Make Ahead and Storage
Storing Leftovers
If you have any Delmonico Potatoes leftover, no worries. Simply cover the dish tightly with foil or transfer to an airtight container. Stored in the refrigerator, they will stay delicious for up to 3 days, making them a convenient option for next-day meals.
Freezing
This recipe freezes well if you want to prepare it in advance. After baking and cooling completely, portion the potatoes into freezer-safe containers. They will keep their creamy goodness for up to 2 months. When ready, thaw overnight in the fridge before reheating.
Reheating
To enjoy your refrigerated or thawed Delmonico Potatoes, reheat gently in the oven at 350°F (175°C) for about 20 minutes, uncovered to preserve the crispy golden topping. Alternatively, microwave on medium power but expect the topping to soften. Oven reheating preserves the dish’s original texture best.
FAQs
Can I use a different type of potato for this recipe?
Russet potatoes are ideal because they hold their shape and absorb flavors beautifully, but you can also use Yukon Gold for a creamier, buttery texture. Just keep in mind that waxier potatoes may not soften as much during baking.
Is there a way to make this dish lighter?
Absolutely! You can substitute half-and-half or whole milk for the heavy cream, though the dish will be less rich and creamy. Using reduced-fat cheeses can also help lighten up the calories without sacrificing much flavor.
Can I prepare this recipe ahead of time before baking?
Yes, you can assemble the potatoes and creamy sauce in the baking dish, cover, and refrigerate for up to 24 hours. When ready, just bake as directed, adding a few extra minutes to ensure the potatoes cook through.
What can I add to make it more flavorful?
Enhance the sauce with a pinch of nutmeg, a dash of smoked paprika, or some fresh thyme to add complexity. Small amounts go a long way, so start with subtle additions to complement the cheesy base.
Can I make this recipe vegetarian?
This Delmonico Potatoes Recipe is vegetarian-friendly as is, but ensure the cheeses you choose are made with vegetarian rennet if that is important to you. Otherwise, it’s a perfect side for vegetarian meals.
