Ingredients

• 3 pieces Large yellow onions
• 4 tablespoons Extra virgin olive oil
• 6 pieces Large eggs
• 1 teaspoon Salt
• 0.5 teaspoons Freshly cracked black pepper
• 1 tablespoon Chopped fresh parsley (optional)
• 1 teaspoon Butter (optional, for greasing)

Directions

Step 1

Peel and slice the onions thinly into half-moons.

Step 2

Heat 3 tablespoons of olive oil in a large nonstick skillet over medium-low heat.

Step 3

Add the sliced onions to the skillet, sprinkle a pinch of salt, and cook slowly, stirring occasionally, for 20-25 minutes until the onions are golden brown and caramelized. Reduce the heat if they start to stick or brown too quickly.

Step 4

While the onions are cooking, crack the eggs into a large bowl. Add the remaining salt, black pepper, and chopped parsley (if using). Beat the eggs until well combined.

Step 5

Once the onions are caramelized, transfer them to the bowl with the eggs. Stir gently to combine. Let the mixture rest for 5 minutes.

Step 6

Wipe the skillet clean and heat the remaining 1 tablespoon of olive oil (or butter, if using) over medium heat.

Step 7

Pour the egg and onion mixture into the skillet, spreading it evenly. Reduce the heat to low and cook for 8-10 minutes until the edges are set and the bottom is golden brown.

Step 8

To flip the tortilla, place a large plate over the skillet, quickly invert the skillet to transfer the tortilla to the plate, then slide it back into the skillet, uncooked side down. Cook for an additional 5 minutes until fully set.

Step 9

Once done, slide the tortilla onto a serving plate and let it cool slightly before slicing into wedges. Serve warm or at room temperature.
