Potatoes Romanoff is a delicious potato side dish. It was first created by a chef in Las Vegas, John Schenk. Potatoes Romanoff reminds me very much of a potato casserole that my mom makes, most often, for Easter dinner.
Potatoes Romanoff is great because it is easy to prepare, and it can be made a day ahead of time. Having the flexibility to have some dishes prepared beforehand is always great when preparing a big family dinner.
Whenever I make potatoes, I look at how many are there and think, there’s no way this is enough. It surprises me every time! Three potatoes doesn’t look like a lot, but once mixed with the other ingredients, it is enough to serve 8-10 people.
Potatoes Romanoff can also be refrigerated for up to 4 days after baking and reheated in the microwave or oven.
