Instructions
- Step 1: Heat 1/2 cup extra virgin olive oil in a large nonstick skillet over medium heat. Add 4 thinly sliced medium potatoes and 1 thinly sliced large onion, seasoning with 1 tsp salt and 1/4 tsp black pepper. Cook gently, stirring occasionally, for 20 minutes until potatoes are tender but not browned.
- Step 2: Meanwhile, crack 6 large eggs into a large bowl and whisk until smooth. Drain the potatoes and onions from the oil and gently fold them into the eggs.
- Step 3: Remove excess oil from the skillet, leaving about 1 tbsp. Pour the egg, potato, and onion mixture back into the skillet and cook over medium-low heat for 6-8 minutes until the edges set and bottom is golden.
- Step 4: Carefully invert the tortilla onto a large plate, then slide it back into the skillet to cook the other side for 4-5 minutes until fully set and lightly browned. Slide onto a serving plate and let rest for 5 minutes before slicing.
