I’ve been eyeing this Swiss Potato Rosti with Salt and Vinegar for a few years, and just finally got around to making it.

Swiss rosti.

Clipped from Bon Appetit, I hesitated making it, because even though the there are relatively few ingredients, the instructions seemed a lot more complicated than necessary. It makes a nice side dish to a roast dinner and is naturally gluten free and Whole30 compliant.  (As an Amazon Affiliate, I earn commission on qualifying links.)

When cooking, I like to break a recipe down into the “big picture” before attempting, which meant reading the whole recipe through to get an idea of the steps involved. Rosti is like hash browns, but formed and baked. For this version, the potatoes are par-boiled, or pre-cooked slightly, then shredded.

Then the onions are tossed with salt and vinegar, before being mixed with the shredded potatoes.

Onions are soaked in salt and vinegar before being combined with the shredded potatoes.

The whole mixture is then pressed into a cake pan and baked. I used a second cake round to press the top of the potato cake down firmly.

Finish the Rosti by browning it under the broiler on both sides.

The nice thing about side dish is that you can bake it ahead of time, then re-heat and finish it under the broiler before serving.

  • 2 pounds russet potatoes, peeled
  • 2 teaspoons Kosher salt
  • 1 Tablespoon olive oil plus additional for brushing on potato cake
  • 1 onion, sliced thin
  • 1 1/2 teaspoons white vinegar (not white wine vinegar)
  • 1/2 teaspoons black pepper


  • In a large pot of boiling, salted water, parboil peeled potatoes, just until knife pierces potato with some resistance, about 15 minutes. Drain and transfer potatoes to a baking sheet and chill until cold, about 30 minutes.
  • Pre-heat oven to 425 degrees F. Line 8" baking pan with parchment and brush with olive oil.
  • Toss onions with vinegar and 1 1/2 teaspoons kosher salt in a bowl and let sit about 5 minutes. 
  • Grate the potatoes with a box grater or food processor. Mix onions and potatoes, black pepper and additional 1/2 teaspoon kosher salt  together and press into baking pan. Press down potato mixture as tightly as possible. Bake at 425 degrees F. until potatoes are golden brown, about 45 minutes.
  • Heat broiler. Remove pan from oven and invert onto a wire rack. Place wire rack on a baking sheet to prevent drips and brush the bottom, (now the top) of the potato cake with 1 1/2 teaspoons olive oil. Broil rosti until top is golden brown. Remove from oven and flip over. Brush with additional olive oil, and brown opposite side.

  1. I too have this recipe in a Swiss cookbook, but have yet to make it. I originally was thinking the salt and vinegar was served with this! Like chips! I may try it that way, too! Never knew it could be made in the oven though! Easy peasy!

  2. I’ve made rosti once, after first experiencing it in Switzerland, and it definitely didn’t have onions or vinegar! They both must really add to the basic rosti. Fun!

  3. 5 stars
    OMG I love this! Salt and vinegar potato chips are my favorite, and this seems like a whole pie of those chips 🙂 Plus potatoes are just the ultimate comfort food. I’m one of those people that puts garlic on everything, so I might just add a touch of garlic and serve it with some sour cream.
