I love eggs. And I love potatoes equally. A Spanish Tortilla combines my two loves. Despite its name, this tortilla is an egg omelette. It uses a cup of oil to cook the potatoes and onions but then the oil is drained off, leaving behind deliciously cooked potatoes wrapped up in an egg omelette seasoned with salt and pepper. And that’s it.
Spanish Omelette (adapted from NY Times Cooking)
Yield: 6-8 servings
567g medium potatoes (about 5 potatoes)
1 medium onion
1 cup olive oil
6 large eggs
Salt and pepper to taste
Peel the potatoes and onions. Using a mandoline, slice the potatoes thinly, then the onions. Set aside.
In a large skillet or wok, heat the oil over medium heat, about 3-4 minutes. Drop in a potato slice. If it bubbles all over, scrape in the rest of the potatoes and the onions. Reduce heat to medium-low. Cook, stirring occasionally with a spatula, about 4 minutes. The oil should bubble gently, not vigorously. Test the potatoes with the tip of a knife. If the potatoes are softened, remove from heat.
Meanwhile, break the eggs into a large bowl. Add salt and pepper to taste, then beat vigorously until frothy. Set aside.
Set a colander over a medium bowl. Pour the potatoes and oil into the colander. Drain the potatoes by swirling the colander. Don’t try turning the potatoes or they will break. Line a baking sheet with two layers of paper towels and gently spread the potatoes on top to soak up the excess oil. Let the potatoes cool slightly. While the potatoes are cooling, add 2 tablespoons of the oil to one 8- or 10-inch skillet. Heat over medium heat. I used an 8-inch skillet to get a thicker omelette. Caution: a thicker omelette will take longer to cook.
Once cooled, then add potatoes to the bowl of beaten eggs. Gently stir with a spatula to coat the potatoes. Once oil is hot, but not smoking, pour in the potatoes, onions, and beaten eggs into the skillet. Reduce the heat to medium low. As the edges set, use a thin spatula to ease up the edges. Slightly tilt the pan to let the raw eggs on top dribble into the pan to cook underneath. The bottom will cook in about 5 minutes. Or, when the top is no longer runny, it’s time to flip the omelette.
Place a 12-inch plate over the top of the skillet. Holding the skillet handle with your dominant hand that the over hand resting on top of the plate, invert both skillet and plate. Slide the omelette back into the skillet to cook the top. Continue cooking the top on medium low heat until browned, 4 minutes. Lift the edge to peek. If it isn’t brown, cook another minute or two.
Serve warm or at room temperature.
