Ingredients
- 3 (about 1 lb) medium potatoes, peeled and thinly sliced
- 1 large yellow onion, thinly sliced
- 1/2 cup extra virgin olive oil
- 6 large eggs
- 1 tsp sea salt
- 1/4 tsp black pepper
Instructions
- Step 1: Heat 1/2 cup extra virgin olive oil in a 10-inch nonstick skillet over medium-low heat until shimmering, about 3 minutes.
- Step 2: Add 3 peeled and thinly sliced medium potatoes and 1 large thinly sliced yellow onion to the skillet. Cook gently, stirring occasionally, for 20 minutes until potatoes are tender but not browned.
- Step 3: In a large bowl, whisk 6 large eggs with 1 tsp sea salt and 1/4 tsp black pepper until combined.
- Step 4: Drain potatoes and onions, reserving 2 tbsp of the olive oil. Gently fold the potato and onion mixture into the eggs.
- Step 5: Heat the reserved 2 tbsp olive oil in the skillet over medium heat, then pour in the egg mixture. Cook for 5-6 minutes until the edges are set and the bottom is golden.
- Step 6: Use a large plate to invert the tortilla, then slide it back into the skillet to cook the other side for 4 minutes until fully set and golden.
- Step 7: Remove from heat and let rest for 5 minutes before slicing and serving warm or at room temperature.
