Ingredients
- 12 oz, peeled and thinly sliced potatoes
- 1/2 cup, thinly sliced yellow onion
- 1/4 cup extra-virgin olive oil
- 6 large eggs
- 1/2 tsp salt
Instructions
- Step 1: In a large skillet, heat 1/4 cup extra-virgin olive oil over medium-low heat until shimmering. Add 1/2 cup thinly sliced yellow onion and cook slowly for 15-18 minutes, stirring occasionally, until deeply golden and caramelized — do not rush the process.
- Step 2: Add 12 oz thinly sliced potatoes to the skillet, pressing them down with a spatula to submerge them in oil. Season with 1/2 tsp salt, cover with a lid, and cook for 20-25 minutes on low heat, flipping every 5 minutes until potatoes are tender but not falling apart.
- Step 3: Whisk 6 large eggs in a bowl until smooth, then pour over the potatoes in the skillet. Cook for 5-7 minutes over medium-low heat, lifting the edges gently with a spatula to let uncooked egg flow underneath, until the eggs are set but still slightly soft in the center.
