There are many, many different versions of Delmonico potatoes, and most of them claim to be the “original” or “real” recipe. I have no idea if the recipe I’m sharing today falls under either of those categories. It was given to me before I was married by a friend…so that’s at least 40 years ago. I’ve been making this Delmonico Potatoes recipe for so long that I don’t need to pull out the tattered recipe card because I know the ingredients by heart!

Why are they called Delmonico Potatoes?

According to many sources online, Delmonico potatoes got their name from a New York City restaurant called Delmonico’s, where the recipe originated in the late 1800’s. The original Delmonico’s closed in 1923, but the recipe lived on. Back then, and for a very long time, the potatoes had to be boiled, peeled, and shredded. It was a lot of work, and it took time, but the end result was so worth the effort. I used this method for years, until I discovered a product called Simply Potatoes.

Simply Potatoes are just that…real potatoes that come shredded, ready to use, and are NOT frozen. They can be found in the refrigerated section of the grocery store, usually around the packaged deli meats. There are a few different varieties, but we like the shredded hash browns the best.

Ingredient Notes + Variations

Using Simply Potatoes literally cuts your time in half, but if you prefer, whole potatoes can be used. You will need 4 to 5 medium to large potatoes, that have been boiled (skins on) until they are fork-tender. It’s better for the potatoes to be slightly undercooked, than overcooked. Peel the cooled potatoes and shred them into a buttered 8 x 8 inch square baking dish. At this point, pick up at step 3 in the recipe card.

*Note: There are recipes on Pinterest that call for frozen hash browns, or frozen cubed potatoes. The honest truth is that I have never tried either, so I don’t know how the potatoes would taste. There would be more moisture, and I don’t know how the frozen potatoes would absorb the liquid. If you try it, let us know!

*Update: one of my readers left a comment saying she made this recipe using defrosted hash browns. She took it to a potluck, and it was a big hit!

Frequently Asked Questions

How do you reheat these potatoes?

Place leftover Delmonico potatoes in a foil-lined baking dish. (Do not use your original baking pan. The bits and pieces left on the sides will burn, and are very hard to remove.) Bake in a 375 degree F oven, uncovered, until bubbly and hot. It usually takes about 15-20 minutes.

Can you freeze Delmonico Potatoes?

Unfortunately, this is not a recipe that freezes well before it’s been baked. It’s best to make them fresh one day, and bake them the next. I have never tried it, but one of my readers left a comment that she loves this recipe because she can freeze the leftovers to use at another time.

Should I use freshly grated cheddar or the bagged stuff?

Either is fine! I have used both, and the potatoes are always wonderful no matter which version is used.

Do I have to use sharp cheddar?

Yes! It’s the sharp cheddar, together with the whipping cream and milk, that make the unique and delicious flavor.

    These potatoes were delish! I did not add nutmeg because I’m not a fan. I did, however, have to add more salt and pepper. I loved the consistency of the them; held up firmly to serve a nice square. Looked so pretty and tasted yummy!

  2. Can I prepare these ahead of time and freeze them before I cook them?

    1. Hi Mona…the honest answer is that I’m not sure. I have never tried it. My first thought was that the potatoes would get mushy from being frozen and then thawed. But again, I just don’t know. If you decide to give it a try, let us know! Thanks, Ann
