Ingredients

Instructions

  1. Step 1: Heat 1/4 cup extra virgin olive oil in a 10-inch nonstick skillet over medium heat until shimmering but not smoking, about 2 minutes.
  2. Step 2: Add 2 medium peeled and thinly sliced russet potatoes and 1 medium thinly sliced yellow onion to the skillet, stirring to coat with oil.
  3. Step 3: Cook for 15 minutes over medium-low heat, stirring occasionally, until potatoes are tender but not browned.
  4. Step 4: In a large bowl, whisk 6 large eggs with 1 tsp salt and 1/4 tsp black pepper until fully combined and slightly frothy.
  5. Step 5: Using a slotted spoon, transfer the potato and onion mixture into the eggs, gently folding to coat without breaking the potatoes.
  6. Step 6: Remove excess oil from the skillet, then pour the egg-potato mixture back into the skillet, spreading evenly.
  7. Step 7: Cook over low heat for 6-8 minutes until the edges are set but the center is still slightly runny.
  8. Step 8: Carefully invert the omelette onto a large plate, then slide it back into the skillet to cook the other side for 4 minutes until fully set and golden.
  9. Step 9: Slide the finished omelette onto a serving plate and let rest for 2 minutes before slicing.
