Allrecipes Community Tips and Praise

"This dish is fabulous," raves Alison Libby. "Made just as written. Get your grill out and pop on some steaks, cook up these potatoes and add a vegetable if you must. And don't forget some wine!"

"This is absolutely incredible," according to Allrecipes Allstar Howard. "It's light, airy, and fluffy! I used Kosher salt, and it was slightly salty for my taste. I will cut back on it a little next time around, and there will be many next times!!!! What a terrific recipe!"

"I made these tonight for dinner alongside a rib eye steak that was 1-1/2 inches thick," says Domsmom95. "They were outstanding. One of the best potato dishes I've ever had. I will be making these again! Super good! Love, love, love!"

Ingredient Checklist


Instructions Checklist
  • Preheat the oven to 400 degrees F (200 degrees C).

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

  • Bake in the preheated oven until potatoes are very tender and easily pierced with a knife, about 1 hour and 15 minutes.

  • Let potatoes cool to room temperature. Unwrap and place on a plate. Cover with plastic wrap and refrigerate until completely chilled, 8 hours to overnight.

  • Preheat the oven to 425 degrees F (220 degrees C). Butter a casserole dish.

  • 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.

  • Bake in the preheated oven until piping hot and the top is browned, 30 to 35 minutes.


You can use 1 1/2 to 2 teaspoons fine salt in place of the kosher salt. Ground black pepper can be used instead of white.

If you do use shallots, note that a little will go a long way because they go in raw. Feel free to saute them in a little butter to take off the sharp, raw edge. Besides shallots, some thinly sliced green onions would be great, as would sauteed leeks, or even just finely minced yellow onions.
