Ingredients

  • 2- 1/2 pounds Potatoes, Peeled And Grated
  • 1 whole Egg, Lightly Beaten
  • 2 Tablespoons Cornstarch
  • 1 teaspoon Salt
  • 1 teaspoon Pepper

  • 1 Tablespoon Butter
  • 1/2 whole Small Onion, Diced
  • 1 pint White Mushrooms, Sliced
  • 4 Tablespoons Sour Cream

  • 4.
  • Add half of potato mixture to pan and flatten it to make sure its even all around.
  • Reduce heat to medium.
  • 5.
  • Cook for 8-10 minutes (checking at 6 minutes) on one side or until golden brown, and cook 6-8 minutes (adding more oil if necessary) on the other side (to flip rosti over, slide the rosti onto a plate first, then cover it with another plate, flip the two plates and then slide the uncooked side back onto the pan).
  • Repeat with the other rosti.
