Ingredients

Instructions

  1. Step 1: Heat 1/4 cup olive oil in a large nonstick skillet over medium heat. Add 3 medium peeled and thinly sliced potatoes and 1 large thinly sliced yellow onion, cooking gently for 20 minutes, stirring occasionally until potatoes are tender but not browned.
  2. Step 2: Add 4 minced garlic cloves to the skillet and cook for 2 minutes until fragrant, stirring carefully to avoid burning.
  3. Step 3: In a large bowl, beat 6 large eggs with 1 tsp salt and 1/2 tsp black pepper. Drain the potatoes, onions, and garlic from the oil and fold them gently into the eggs.
  4. Step 4: Wipe out the skillet, add 2 tbsp olive oil, and heat over medium. Pour the egg mixture into the skillet, cooking for 5-6 minutes until edges set.
  5. Step 5: Using a large plate, carefully flip the omelette and slide it back into the skillet. Cook an additional 4-5 minutes until fully set and golden on both sides.
  6. Step 6: Slide the tortilla onto a serving plate, garnish with 2 tbsp chopped fresh parsley if desired, and serve warm with lemon wedges.
