Breakfast Tortilla Espanola

 

Ingredients:

1½ cups extra-virgin olive oil

2 pounds large Yukon Gold potatoes, peeled, quartered, cut into ¼-inch slices 

1 onion, quartered, thinly sliced

2½ teaspoons kosher salt

8 large eggs, beaten to blend

Method: 

1. Step 1

   Heat oil in a large ovenproof skillet over medium heat. Add potatoes, onion, and salt. Use a heatproof spatula to coat potatoes with oil. When oil begins to bubble, reduce heat to medium-low and cook, turning frequently, until potatoes are tender but not browned, 20–25 minutes.

   Step 2

   Using a slotted spoon, transfer potatoes and onion to a large heatproof bowl. Add eggs and stir gently to combine; do not break up potatoes. Strain oil into a glass measuring cup; wipe out skillet.

   Step 3

   Heat 3 Tbsp. reserved oil from measuring cup in skillet over medium-high heat. Add egg-potato mixture and cook, stirring constantly but gently to keep potatoes intact, until eggs begin to set (eggs will look scrambled), about 2 minutes. Spread mixture in an even layer; reduce heat to medium-low. Preheat broiler to high.

   Step 4

   Cook tortilla, shaking pan occasionally to prevent it from sticking, until eggs are nearly cooked through, about 12 minutes. Transfer skillet to oven and broil until top of tortilla is just cooked, about 2 minutes.

   Step 5

   Remove from oven. Invert a large plate over skillet. Using oven mitts (skillet and potatoes will be very hot; use caution), hold plate firmly over skillet and flip, releasing tortilla onto plate. Let sit at room temperature for at least 20 minutes and up to 2 hours before serving.
