The classic dish of Lyonnaise potatoes is named after the city of Lyon, in France. This French dish requires lightly boiling sliced potatoes before sautéing in butter with lightly caramelized onions. The potatoes are finished with fresh chopped parsley. Alternatively, the potatoes can be baked in the oven.

Slice the potatoes into rounds nearly 1/2-inch in thickness so they will not fall apart easily as you sauté and turn them. For cooking, a nonstick or seasoned cast iron skillet are good choices.


  • 1 large sweet onion
  • 6 tablespoons butter (divided)
  • 2 pounds russet potatoes (or similar baking potatoes)
  • 1 tablespoon extra-virgin olive oil
  • Kosher salt (to taste)
  • Freshly ground black pepper (to taste)
  • Garnish: parsley (fresh minced)

Steps to Make It

Note: there are two great methods you can use to create these Lyonnaise Potatoes: using the stovetop or the oven.

  3. Melt 4 tablespoons of butter in a large skillet over medium-low heat. When the foaming subsides, add the onion slices. Cook for about 6 to 8 minutes, or until the onion has softened and browned, stirring frequently. Remove the onion to a plate and set aside.

Add the potatoes to the hot fat and cook for 12 to 15 minutes, or until the slices are browned, stirring and turning frequently. Try to keep the potato slices intact while turning and stirring.
