What Makes a Great Tortilla Española?

Before we dive into the recipe, let’s understand what elevates a good tortilla española to a great one. The key lies in the balance of flavors, textures, and the cooking process:

• Perfectly Cooked Potatoes: The potatoes should be tender and almost melting in your mouth, but not mushy.
• Sweet, Soft Onions: The onions should be caramelized and add a subtle sweetness that complements the potatoes.
• Creamy Interior: The inside of the tortilla should be slightly runny and creamy, not completely solid. This is achieved by careful cooking and attention to detail.
• Golden-Brown Exterior: The outside should be a beautiful golden-brown color, slightly crisp and caramelized.
• Proper Salting: Salting the potatoes and onions at the right time is crucial for bringing out their flavors.
• The Flip: The flip can be intimidating, but with the right technique, it’s surprisingly easy and essential for achieving that perfect round shape.

Ingredients for Tortilla Española

The beauty of this dish lies in its simplicity. You only need a few basic ingredients:

• 1 kg (2.2 lbs) Potatoes: Choose a starchy variety like Russet or Yukon Gold. They will become soft and creamy when cooked.
• 1-2 Large Onions: Yellow or white onions work well. The amount depends on your preference; some prefer a milder onion flavor, while others like a more prominent one.
• 6-8 Large Eggs: The number of eggs depends on the size of your potatoes and onions. You want enough to bind everything together without making the tortilla too eggy.
• Olive Oil: Extra virgin olive oil is preferred for its flavor, but regular olive oil can also be used. You’ll need a generous amount for cooking the potatoes and onions.
• Salt: For seasoning.

Equipment You’ll Need

• Large Non-Stick Skillet: A 10-12 inch non-stick skillet is ideal. The non-stick surface is essential for preventing the tortilla from sticking and making the flip easier.
• Large Bowl: For mixing the potatoes, onions, and eggs.
• Slotted Spoon: For removing the potatoes and onions from the oil.
• Plate or Lid: Slightly larger than the skillet, for flipping the tortilla.
• Cutting Board: For preparing the potatoes and onions.
• Sharp Knife: For chopping the vegetables.

Step-by-Step Instructions: Making the Perfect Tortilla Española

Now, let’s get started with the detailed instructions:

Step 1: Preparing the Potatoes and Onions

1. Peel the Potatoes: Peel the potatoes and cut them into roughly 1/4-inch thick slices. Try to keep the slices relatively uniform in size for even cooking.
2. Peel and Slice the Onions: Peel the onions and slice them thinly. You can slice them into half-moons or dice them, depending on your preference.

Step 2: Cooking the Potatoes and Onions

1. Heat the Olive Oil: Pour a generous amount of olive oil (about 1-2 cups) into the large non-stick skillet. The oil should be deep enough to almost submerge the potatoes. Heat the oil over medium heat. Don’t let the oil get too hot, or the potatoes will brown too quickly without cooking through.
2. Add the Onions: Once the oil is hot, add the sliced onions. Cook them over medium-low heat, stirring occasionally, until they become soft, translucent, and slightly caramelized. This will take about 15-20 minutes. The key is to cook them slowly and gently to bring out their sweetness. Don’t rush this step!
3. Add the Potatoes: Add the sliced potatoes to the skillet with the onions. Make sure the potatoes are mostly submerged in the oil. If not, add more oil.
4. Cook the Potatoes and Onions: Cook the potatoes and onions over medium-low heat, stirring occasionally, until the potatoes are tender and cooked through. This will take about 20-30 minutes. The potatoes should be easily pierced with a fork. Again, be patient and don’t rush the cooking process. The goal is to cook the potatoes in the oil, not to fry them. You want them to be soft and almost melting.
5. Season with Salt: Season the potatoes and onions generously with salt. Taste and adjust as needed. The salt is crucial for bringing out the flavors of the potatoes and onions.
6. Remove from Heat: Once the potatoes are cooked through, remove the skillet from the heat.
7. Drain the Potatoes and Onions: Using a slotted spoon, carefully remove the potatoes and onions from the oil and transfer them to the large bowl. Allow the excess oil to drain off. Reserve the olive oil in a heat-proof container; you can reuse it for other cooking purposes.

Step 3: Preparing the Egg Mixture

1. Whisk the Eggs: In a separate bowl, whisk the eggs until they are light and frothy. Season with a pinch of salt. Don’t over-whisk the eggs; just whisk them until they are combined.
2. Combine Potatoes, Onions, and Eggs: Pour the whisked eggs over the drained potatoes and onions in the large bowl. Gently stir to combine, making sure the potatoes and onions are evenly coated with the egg mixture.
3. Let the Mixture Rest: Let the mixture rest for at least 10-15 minutes. This allows the potatoes to absorb some of the egg and creates a creamier texture. Some people even let it rest for an hour or more.

Step 4: Cooking the Tortilla Española

1. Heat the Skillet: Heat a tablespoon or two of the reserved olive oil in the same non-stick skillet over medium heat. Make sure the bottom of the skillet is evenly coated with oil.
2. Pour the Mixture into the Skillet: Pour the potato, onion, and egg mixture into the heated skillet. Spread it out evenly with a spatula.
3. Cook the Tortilla: Cook the tortilla over medium-low heat for about 8-10 minutes, or until the bottom is set and lightly golden brown. Use a spatula to gently lift the edges of the tortilla occasionally to prevent it from sticking. You can also gently shake the skillet to ensure even cooking. The center of the tortilla should still be slightly runny.

Step 5: The Flip!

This is the most crucial and potentially nerve-wracking step, but with a little practice, it becomes easy:

1. Prepare the Plate or Lid: Place a large plate or lid (slightly larger than the skillet) over the skillet.
2. Invert the Tortilla: Holding the plate or lid firmly against the skillet, carefully and quickly invert the tortilla onto the plate. Be careful not to burn yourself with any hot oil that may escape.
3. Slide the Tortilla Back into the Skillet: Add another tablespoon of olive oil to the skillet. Carefully slide the tortilla from the plate back into the skillet, uncooked side down. Use a spatula to tuck in any edges that may have folded over.
4. Cook the Second Side: Cook the tortilla for another 5-7 minutes, or until the second side is set and lightly golden brown. Again, the center should still be slightly runny.

Step 6: Serving and Enjoying Your Tortilla Española

1. Slide onto a Plate: Carefully slide the finished tortilla onto a serving plate.
2. Let it Rest: Let the tortilla rest for a few minutes before slicing. This allows the flavors to meld together.
3. Slice and Serve: Slice the tortilla into wedges and serve warm or at room temperature.

Tips for a Perfect Tortilla Española

• Don’t Overcook the Potatoes: The potatoes should be tender but not mushy.
• Cook the Onions Slowly: Caramelizing the onions is key to adding sweetness and depth of flavor.
