How to Make Delmonico Potatoes Recipe
Step 1: Prepare Your Oven and Bakeware
Start by preheating your oven to 375°F (190°C). Don’t forget to grease a 9×13-inch baking dish thoroughly—this step is key to preventing sticking and ensuring those golden edges form perfectly during baking.
Step 2: Sauté the Onion and Garlic
In a large skillet over medium heat, melt the butter and pulse in the olive oil. Add the diced onion and minced garlic, then sauté for about 3-4 minutes. You’ll want to cook them until they’re softened and fragrant, setting the stage for the creamy sauce to come later.
Step 3: Create the Creamy Cheese Sauce
Once your aromatics are ready, stir in the heavy cream along with both cheeses, cheddar and Parmesan. Season with salt and pepper. Keep stirring gently until the cheese melts and the sauce thickens to a dreamy, luscious consistency that will coat the potatoes beautifully.
Step 4: Layer the Potatoes in the Baking Dish
Arrange your peeled and thinly sliced russet potatoes evenly in the greased baking dish. Pour the warm creamy cheese sauce evenly over the top, making sure every slice gets coated in that rich blanket of flavor. This slow blend of layers is what makes the dish melt in your mouth.
Step 5: Bake to Creamy, Golden Perfection
Cover your baking dish with foil and place it in the oven. Bake for 40-45 minutes, or until the potatoes are tender when pierced with a fork. Then, remove the foil and bake for an additional 10 minutes. This step is crucial—it lets the top get that irresistible, golden brown crust you’ll adore.
Step 6: Garnish and Serve Warm
Once out of the oven, sprinkle freshly chopped parsley over the dish for color and a fresh herbaceous note. Serve this creamy, cheesy masterpiece immediately to enjoy it at its absolute best, warm and comforting.

Make Ahead and Storage
Storing Leftovers
Delmonico Potatoes Recipe leftovers keep beautifully in an airtight container in the refrigerator for up to three days. Just cover tightly to maintain moisture and flavor.
Freezing
While best enjoyed fresh, you can freeze the dish before baking. Assemble as directed, cover with foil, and freeze for up to two months. When ready to eat, thaw overnight in the fridge and bake as usual, adding extra baking time if still chilled.
Reheating

FAQs
Can I use different types of potatoes for this recipe?
Russet potatoes are ideal because of their starchy texture, which absorbs flavors and softens beautifully. However, Yukon Gold potatoes can be a good alternative if you prefer a waxier, creamier texture.
Is it possible to make a lighter version of this Delmonico Potatoes Recipe?
You can lighten the dish by substituting half-and-half for heavy cream and reducing the butter slightly, but keep in mind it may affect the richness and creaminess that defines the recipe.
How thin should I slice the potatoes?
Slice the potatoes about 1/8 inch thick to ensure they cook evenly and absorb the creamy sauce well without becoming mushy.
Can I prepare this dish in advance?
Absolutely! Assemble and refrigerate it before baking. Just bring to room temperature before placing it in the oven to ensure even cooking.
What kind of cheese works best if I want a different flavor profile?
Gruyere or Fontina cheeses are excellent substitutes for a nuttier, more complex flavor. Feel free to experiment, but remember they’ll change the classic taste of this Delmonico Potatoes Recipe.

- 2 cloves garlic, minced
- 1 1/2 cups heavy cream
- 1/2 cup grated cheddar cheese
- 1/2 cup grated Parmesan cheese
- Salt and pepper to taste
Garnish
- Fresh parsley for garnish
Instructions
- Preheat and Prepare: Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish to prevent sticking and prepare for layering the potatoes and sauce.
- Sauté Aromatics: In a large skillet, heat the butter and olive oil over medium heat. Add diced onion and minced garlic and sauté for 3-4 minutes until softened and fragrant, building a flavorful base for the sauce.
- Make the Creamy Cheese Sauce: Stir in the heavy cream, grated cheddar cheese, grated Parmesan cheese, salt, and pepper into the skillet. Cook the mixture, stirring occasionally, until the cheeses melt fully and the sauce thickens slightly, creating a rich, creamy topping.
- Assemble the Dish: Layer the peeled and sliced potatoes evenly in the prepared baking dish. Pour the creamy cheese sauce over the potatoes, making sure all slices are well coated for uniform cooking and flavor.
- Bake Covered: Cover the baking dish tightly with foil and bake in the preheated oven for 40-45 minutes. This slow baking softens the potatoes and infuses them with the creamy sauce.
- Finish Baking Uncovered: Remove the foil and bake for an additional 10 minutes. This step allows the top to turn a beautiful golden brown and develop a slightly crispy texture.
- Garnish and Serve: Once baked, sprinkle fresh parsley over the top for added color and freshness. Serve warm as a rich, comforting side dish.

- If you prefer a lighter version, substitute half-and-half for heavy cream, though sauce will be less rich.
- Cheese types can be swapped according to preference; Gruyere or mozzarella also work well.
- Covering the dish while baking prevents drying out and ensures tender potatoes.
- Let the dish rest for 5 minutes after baking to thicken the sauce slightly before serving.
