Delmonico Potatoes: A Rich and Creamy Potato Casserole

by

Introduction

Few side dishes are as universally beloved as a well-made potato casserole, and Delmonico Potatoes stand out as a classic comfort food favorite. Named after the famous Delmonico’s Restaurant in New York, this dish features layers of shredded hash browns baked in a velvety, cheese-laden cream sauce. The result is a decadent, golden-brown casserole that pairs perfectly with roasted meats, holiday feasts, or any meal that calls for an indulgent accompaniment.

Unlike traditional scalloped potatoes, Delmonico Potatoes use shredded hash browns for a lighter, more delicate texture while still delivering rich, cheesy flavor in every bite. The combination of heavy cream, sharp cheddar, and aromatic seasonings creates a luxurious dish that is both simple to prepare and impressive to serve. Whether you’re hosting a dinner party or simply craving a comforting side, this recipe is sure to become a staple in your kitchen.

Ingredients

  • 1 (32 oz) package frozen shredded hash browns, thawed
  • 1 cup whole milk
  • 1 cup heavy cream
  • 1 teaspoon dry mustard
  • 1 teaspoon salt
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon dried parsley
  • 1/4 teaspoon black pepper
  • 4 cups sharp cheddar cheese, grated (divided)
  • 2 tablespoons butter (for greasing the baking dish)

Step-by-Step Instructions

Step 1: Preheat and Prepare

  1. Preheat the oven to 375°F (190°C).
  2. Lightly grease a 9×13-inch baking dish with butter to prevent sticking.

Step 2: Mix the Cream Sauce

  1. In a large mixing bowl, whisk together the milk, heavy cream, dry mustard, salt, garlic powder, dried parsley, and black pepper until well combined.
  2. Stir in 3 cups of the grated cheddar cheese, reserving 1 cup for the topping.

Step 3: Combine with Potatoes

  1. Add the thawed shredded hash browns to the cream and cheese mixture.
  2. Gently fold everything together until the potatoes are evenly coated.

Step 4: Assemble and Bake

  1. Transfer the potato mixture to the prepared baking dish, spreading it into an even layer.
  2. Sprinkle the remaining 1 cup of cheddar cheese over the top.
  3. Cover the dish with aluminum foil and bake for 40 minutes.
  4. Remove the foil and bake for an additional 15-20 minutes, or until the top is bubbly and golden brown.

Step 5: Rest and Serve

  1. Let the casserole rest for 5-10 minutes before serving to allow the sauce to thicken slightly.
  2. Garnish with a sprinkle of fresh parsley or extra black pepper if desired.

Tips for the Best Delmonico Potatoes

  • Thaw the hash browns completely to ensure even cooking.
  • Use freshly grated cheese for the best melt and flavor—pre-shredded cheese contains anti-caking agents that can affect texture.
  • For extra richness, substitute half of the milk with additional heavy cream.
  • Add a crispy topping by mixing breadcrumbs with melted butter and sprinkling over the cheese before baking uncovered.
  • Make ahead option: Assemble the casserole up to a day in advance, cover, and refrigerate. Add 10-15 minutes to the baking time if cooking from cold.

Serving Suggestions

Delmonico Potatoes are a versatile side dish that complements a wide variety of main courses. Consider serving them with:

  • Roasted meats such as prime rib, baked ham, or roasted chicken.
  • Holiday feasts—they’re a perfect alternative to traditional mashed potatoes.
  • Grilled steaks or pork chops for a hearty weeknight meal.
  • A simple green salad to balance the richness of the dish.

Delmonico Potatoes are the ultimate comfort food—creamy, cheesy, and irresistibly flavorful. This dish elevates humble ingredients into a show-stopping side that’s perfect for both casual family dinners and special occasions. The simplicity of the recipe makes it accessible to cooks of all skill levels, while the luxurious results ensure it will impress even the most discerning guests.

Once you try this version, you’ll understand why it has remained a classic for generations. Whether served at a holiday gathering or as a comforting weeknight side, Delmonico Potatoes are guaranteed to earn a permanent place in your recipe collection.
