These Delmonico potatoes are super easy to prepare with leftover or freshly cooked and diced potatoes. The potatoes are baked in a white sauce with shredded cheese and buttery breadcrumbs.

Named after the New York restaurant where they were created, Delmonico potatoes date back to the 19th century. This version is made with a simple white sauce and shredded Swiss or cheddar cheese.

Perfect to serve as a side dish with baked chicken or pork chops, grilled steak or ham, and your favorite veggies.
