What do Eggs Benedict, Chicken à la King, and Lobster Newburg have in common? They were all dishes born at Delmonico’s restaurant in New York City, which opened in 1837 and is lauded as “America’s first fine-dining establishment.”
But there’s another delicious specialty that was invented at the historic steakhouse: Delmonico Potatoes. The comforting cheesy casserole dates back to decades before the Civil War. Abraham Lincoln even dined at the restaurant during the war and was rumored to be a fan of the potatoes. Once after a meal, he reportedly told Lorenzo Delmonico, the founder of the restaurant, “In Washington, where I live, there are many mansions, but no cooks like yours.”
What Are Delmonico Potatoes?
So there’s a chance Lincoln liked them, but what exactly are they? What we eat today varies from what Delmonico’s patrons enjoyed in the 19th century. Our most popular Delmonico Potatoes recipe is a shredded potato casserole made with a cheesy sour-cream-based sauce. However, the historical recipe uses heavy whipping cream and Parmesan to give the potatoes their creamy bite.

It’s easy to skip the first few steps of making Delmonico Potatoes. You’re welcome to boil, refrigerate, and grate your own spuds, but there’s no shame in buying pre-shredded hash browns either. Either way, once your potatoes are ready, set the oven to 350 degrees F and mince onions that will sweeten the potatoes once cooked.
Combine the onions with melted butter, parsley, and salt and pepper in a small bowl. In another bowl, whip together sour cream and milk. I tried replacing those last two ingredients with Greek yogurt and heavy cream to delicious success.
In a greased casserole dish, spread half of the potatoes evenly across the bottom. Layer half of the onion-butter combination over the potatoes, then pour the sour cream and milk over that. Cover with half a cup of cheese (I prefer a Cheddar blend). Repeat the process with potatoes, butter mixture, creams, and cheese. Bake it for an hour, until the cheese on top is lightly browned.
The result? A creamy, cheesy delight with a story to share.
