Steakhouse Potatoes Romanoff

Steakhouse Potatoes Romanoff

My potatoes Romanoff is an ideal dish for big holiday gatherings since you can make it the day before and bake it when needed. Featuring shredded baked russet potatoes and sweet shallots fluffed up with sour cream and lots of Cheddar cheese, this delicious potato casserole is the perfect side dish for any cut of steak. Chef John Schenk taught me how to make this special potato gratin ten years ago at his restaurant Strip House in Las Vegas.

    Wrap each potato in foil and place on a baking sheet. Poke holes into potatoes using a knife.

    Leave skin on the potatoes. Use a cheese grater to shred potatoes into a large bowl.

    Add shallots to the potatoes; season with salt, white pepper, and cayenne. Toss with two forks until well combined. Add Cheddar cheese and mix well. Gently toss in sour cream until barely combined. Transfer mixture into the prepared baking dish, piling it up high, then patting it down very lightly.
