What Kind of Potatoes Work Best for Delmonico Potatoes?

Russet potatoes are the go-to for Delmonico Potatoes. Their high starch content creates a fluffier, creamier texture when baked. Yukon Gold potatoes also work well, giving a naturally buttery flavor and golden hue to the dish.

Ingredients for the Creamy Delmonico Potatoes

• Russet Potatoes: The foundation of the dish. Sliced thinly, they soak up the creamy sauce beautifully.
• Heavy Cream: Delivers that luxurious, rich texture Delmonico potatoes are known for.
• Milk: Lightens the cream slightly while keeping things rich.
• Butter: Adds richness and helps develop the roux base of the sauce.
• Flour: Thickens the sauce for that perfect cling to each potato layer.
• Garlic: For aromatic depth.
• White Onion: Adds mild sweetness and savory balance.
• Shredded Cheddar Cheese: Melts beautifully and provides a golden top crust.
• Parmesan Cheese: Boosts flavor and adds a nutty, sharp bite.
• Salt & Pepper: To season every layer just right.

How To Make the Creamy Delmonico Potatoes

Step 1: Prep the Potatoes

Peel and thinly slice about 3 pounds of russet potatoes using a mandoline or a sharp knife. Place in cold water to prevent browning while you prep the sauce.

Step 2: Make the Cream Sauce

In a saucepan, melt butter over medium heat. Add diced onions and minced garlic; sauté until soft. Stir in flour to form a roux, cooking for 1-2 minutes. Gradually whisk in milk and cream. Cook until the sauce thickens, then add salt, pepper, and a bit of shredded cheddar and parmesan.

Step 3: Layer and Assemble

Drain and pat dry your potato slices. In a greased baking dish, layer potatoes, then spoon over the cream sauce. Repeat layers until everything is used. Top with more cheese.

Step 4: Bake to Golden Perfection

Cover with foil and bake at 375°F for 40 minutes. Remove foil and bake another 20-25 minutes until the top is bubbling and golden brown.

Step 5: Rest and Garnish

Let the casserole sit for 10-15 minutes before serving to allow the sauce to thicken slightly. Garnish with fresh chopped parsley if desired.

How to Serve and Store Creamy Delmonico Potatoes

These potatoes are best served hot and fresh out of the oven when the cheese is gooey and the edges are golden. They’re a knockout at holiday tables, but they also hold their own alongside a weeknight steak.

Leftovers? Simply store in an airtight container in the refrigerator for up to 4 days. Reheat in the oven for best texture, or microwave for convenience. They freeze well, too—wrap tightly in foil and freeze for up to 2 months.
