Equipment

  • Large skillet or cast iron pan
  • Medium saucepan
  • Sharp knife
  • Cutting board
  • Mixing Bowl
  • Spatula or wooden spoon
  • Colander
  • Measuring spoons

Ingredients
  

For the Potatoes

  • 2 pounds Yukon Gold potatoes
  • 3 tablespoons unsalted butter
  • 2 tablespoons olive oil
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper

For the Caramelized Onions

  • 2 large yellow onions thinly sliced
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1/2 teaspoon salt

Finishing Ingredients

  • 2 tablespoons fresh parsley chopped
  • Extra salt and pepper to taste

Instructions
 

Step 1: Prepare the Potatoes

  • Wash and peel the Yukon Gold potatoes. Slice them into thin rounds about 1/4 inch thick.
  • Keeping the slices even ensures they cook at the same speed.

Step 2: Parboil the Potatoes

  • Bring a pot of salted water to a boil and add the potato slices. Cook for about 5 minutes until slightly tender but not fully soft.
  • Drain the potatoes carefully and let them cool for a few minutes.
  • This step helps the potatoes become creamy inside while still crisping beautifully later.

Step 3: Start the Onions

  • Heat butter and olive oil in a skillet over medium heat. Add the sliced onions and sprinkle with salt.
  • Cook slowly for about 15 minutes, stirring occasionally.
  • The onions should soften, darken, and turn golden brown.

Step 4: Crisp the Potatoes

  • In another large skillet, heat butter and olive oil over medium-high heat.
  • Add the potato slices in a single layer and cook for several minutes without stirring. This helps them develop a golden crust.
  • Flip the slices and cook the other side until crispy.

Step 5: Combine Potatoes and Onions

  • Once the onions are deeply caramelized and the potatoes are golden, gently combine them in the skillet.
  • Toss everything carefully so the potatoes stay intact.

Step 6: Season and Finish

  • Add black pepper and adjust salt to taste.
  • Sprinkle fresh parsley over the top for color and brightness.

Step 7: Serve

  • Serve the potatoes immediately while they are hot and crispy.
  • They pair beautifully with steak, roasted chicken, or grilled vegetables.
