Delmonico Potatoes Recipe – Ingredients & Substitutions

Before diving into the cooking process, let’s break down the key ingredients and possible substitutions to customize this dish to your liking.

Ingredients List

Ingredient	Quantity	Possible Substitutions
Simply Potatoes (shredded hash browns)	20 oz. (1 bag)	Fresh shredded potatoes, frozen hash browns (thawed)
Milk (1% or any kind)	¾ cup	Whole milk, half-and-half, or unsweetened almond milk
Whipping Cream	¾ cup	Heavy cream, evaporated milk, or full-fat coconut milk
Kosher Salt	1 tsp	Sea salt or table salt (adjust to taste)
Dry Mustard	1 tsp	Dijon mustard (1 tbsp) or yellow mustard (1 tsp)
Black Pepper & Nutmeg	Dash each	White pepper, allspice, or omit nutmeg if preferred
Sharp Cheddar Cheese (shredded)	1 cup	Gruyère, Monterey Jack, or a blend of cheeses
Butter (divided)	3 tbsp	Margarine or olive oil (for dairy-free option)
Paprika	For garnish	Smoked paprika or cayenne for a kick

Step-by-Step Cooking Instructions

Step 1: Prepare the Casserole Dish

Butter an 8×8-inch baking dish generously to prevent sticking.
Spread the entire bag of Simply Potatoes (or shredded potatoes) evenly in the dish.

Step 2: Make the Cheese Sauce

In a medium saucepan over medium-high heat, combine:
- ¾ cup milk
- ¾ cup whipping cream
- 1 tsp kosher salt
- 1 tsp dry mustard
- A dash of black pepper & nutmeg
Whisk continuously until the mixture is almost boiling (small bubbles will form at the edges).
Reduce heat to low and add 1 cup shredded sharp cheddar cheese.
Stir until the cheese is fully melted and the sauce is smooth.

Step 3: Assemble the Casserole

Pour the cheese sauce evenly over the potatoes.
Let it cool slightly before adding 3 tbsp of butter (sliced into small pieces) on top.
Sprinkle with paprika for color and flavor.

Step 4: Refrigerate (Key Step!)

Cover tightly with plastic wrap and refrigerate for at least 12 hours (or overnight).
(This allows the potatoes to absorb the flavors and ensures a creamy texture.)

Step 5: Bake to Perfection

Preheat oven to 350°F (175°C).
Remove the casserole from the fridge and discard plastic wrap.
Bake uncovered for 45 minutes, or until the top is golden brown and bubbly.
Let it rest for 5-10 minutes before serving.

The History and Origin of Delmonico Potatoes

Introduction to Delmonico Potatoes

Delmonico Potatoes are a classic American side dish known for their rich, creamy texture and indulgent cheesy flavor. Named after the famous Delmonico’s Restaurant in New York City, this dish has been a staple in American cuisine since the 19th century. Unlike traditional scalloped potatoes or au gratin potatoes, Delmonico Potatoes are distinguished by their mustard-infused cheese sauce, which adds a unique depth of flavor.

The Legacy of Delmonico’s Restaurant

Delmonico’s, established in 1837, was one of the first fine-dining restaurants in the United States. It was renowned for its elegant dishes and innovative cooking techniques, many of which became American classics. The restaurant introduced several iconic dishes, including:

Eggs Benedict
Baked Alaska
Delmonico Steak
Delmonico Potatoes

The exact origin of Delmonico Potatoes is debated, but it is widely believed that the dish was created to complement the restaurant’s famous Delmonico Steak. The creamy, cheesy potatoes provided the perfect balance to the rich, buttery steak, making them an instant hit among diners.

Evolution of the Recipe

Over time, the recipe for Delmonico Potatoes evolved as home cooks adapted it for easier preparation. The original version likely used freshly sliced potatoes and a homemade béchamel sauce, but modern versions (like the one in this guide) often use pre-shredded potatoes and simplified cheese sauces for convenience.

Despite these adaptations, the core elements remain the same:

✅ Creamy, cheesy sauce
✅ Tender, layered potatoes
✅ A golden, buttery crust

Step-by-Step Cooking Tips for Perfect Delmonico Potatoes

Choosing the Right Ingredients

The key to making the best Delmonico Potatoes lies in selecting high-quality ingredients. Here’s what to keep in mind:

1. Potatoes

Simply Potatoes (shredded hash browns) – The easiest option, as they’re pre-shredded and ready to use.
Fresh Potatoes – If using fresh, opt for russet or Yukon Gold for the best texture. Peel and shred them just before assembling.
Frozen Hash Browns – Thaw and drain excess moisture to prevent a soggy casserole.

2. Dairy (Milk, Cream & Cheese)

Whole milk or half-and-half – Adds richness.
Heavy cream – Makes the sauce extra velvety.
Sharp cheddar cheese – Provides a tangy flavor that balances the creaminess.

3. Seasonings

Dry mustard – A signature ingredient that adds depth.
Nutmeg – A pinch enhances the sauce’s warmth.
Paprika – Adds color and a subtle smokiness.

Avoiding Common Mistakes

Mistake #1: Skipping the Refrigeration Step

Why It Matters: Letting the casserole sit for 12 hours allows the potatoes to absorb the sauce, ensuring a creamy (not watery) texture.
Quick Fix: If short on time, refrigerate for at least 4 hours.

Mistake #2: Overbaking

Signs It’s Done: The top should be golden brown, and the edges bubbly.
Prevent Overcooking: Check at the 40-minute mark.

Mistake #3: Using Low-Fat Dairy

Best Choice: Full-fat milk, cream, and cheese prevent a grainy or thin sauce.

Pro Tips for Extra Flavor

🔹 Add Garlic – Sauté 1 minced garlic clove in butter before making the sauce.
🔹 Crispy Topping – Mix breadcrumbs with melted butter and sprinkle on top before baking.
🔹 Spice It Up – Add a dash of cayenne pepper for heat.

By following these tips, you’ll achieve restaurant-quality Delmonico Potatoes every time!
