Preparation Steps

• Wash and peel the potatoes if desired. Cut into 1/4-inch slices or 1/2-inch cubes for even frying.
• Slice the onion into thin half-moons so they cook evenly with the potatoes.
• Heat a large skillet over medium-high heat. Add the olive oil and let it warm until shimmering.
• Add the potatoes in a single layer if possible. Let them cook undisturbed for 5-7 minutes to develop a golden crust, then stir or flip to brown the other side.
• When potatoes are starting to soften and brown, add the butter and sliced onions to the pan. Stir to combine and spread the ingredients evenly.
• Continue to cook, stirring occasionally, until potatoes are tender and onions are caramelized, about 8-10 more minutes. Adjust heat as needed to prevent burning.
• Season with salt and freshly ground black pepper to taste. Serve hot as a side dish.
