Ingredients

  • 3 pounds russet potatoes
  • 1 large onion thinly sliced
  • 4 tablespoons unsalted butter divided
  • 2 tablespoons extra virgin olive oil
  • 2 tablespoons fresh parsley chopped
  • salt to taste
  • pepper to taste

Instructions

  • Start by peeling the russet potatoes. Once peeled, slice them into uniform ¼-inch thick rounds for even cooking.
  • Soak the sliced potatoes in a bowl of cold water for about 30 minutes to remove excess starch and prevent browning. Drain and pat dry with a clean kitchen towel.
  • In a large skillet, melt 2 tablespoons of unsalted butter and 2 tablespoons of extra virgin olive oil over medium heat. Add the thinly sliced onions and a pinch of salt. Cook for 10-15 minutes, stirring occasionally, until caramelized and golden brown. Remove onions and set aside.
  • In the same skillet, add the remaining 2 tablespoons of butter. Once melted, add the sliced potatoes in an even layer. Season with salt and pepper. Cook without stirring for 5-7 minutes until the bottom side begins to brown.
  • Carefully flip the potatoes using a spatula to brown the other side. Add the caramelized onions back into the skillet and gently mix. Cook for another 10-15 minutes, stirring occasionally, until potatoes are tender and golden brown.
  • Remove the skillet from heat. Sprinkle chopped fresh parsley over the potatoes. Serve warm and enjoy!

Notes

  • Soaking potatoes is essential for crispiness; don’t skip this step.
  • Cook potatoes in batches if your skillet is small to avoid overcrowding and steaming.
  • Use a mix of butter and olive oil to get rich flavor without burning the butter.
