Ingredients for Classic Spanish Tortilla
- 6 large eggs
- 4 medium-sized potatoes (preferably waxy, like Yukon Gold)
- 1 medium onion
- Olive oil (for frying)
- Salt (to taste)
Optional Add-ins:
- Diced red pepper
- Cooked chorizo
- Fresh spinach
- Cheese (Manchego, cheddar, or your favorite melting cheese)
- Fresh herbs like parsley or chives
Preparing the Ingredients
Prepping the Potatoes and Onion
- Peel the potatoes and slice them thinly—aim for uniform, 1/8-inch slices for even cooking.
- Slice the onion thinly to allow it to caramelize gently during cooking.
This preparation step sets the foundation for a soft, flavorful tortilla.
Cooking the Potatoes and Onions
- Heat a generous amount of olive oil in a large nonstick or cast iron skillet over medium heat.
- Add the sliced potatoes and onions, seasoning lightly with salt.
- Cook slowly for about 15–20 minutes, stirring occasionally, until the potatoes are soft and lightly golden. Avoid browning them too much.
Tip: Use enough oil to submerge the potatoes partially—this helps them cook evenly and prevents sticking.
Mixing with Eggs
- While the potatoes and onions are cooking, crack the eggs into a large mixing bowl and beat lightly with a pinch of salt.
- Once the potatoes and onions are fully cooked, drain them using a slotted spoon or sieve to remove excess oil. Reserve the oil for later use.
- Let the mixture cool slightly, then gently fold the potatoes and onions into the beaten eggs. Let it rest for about 5 minutes.
This resting step allows the eggs to absorb the flavors and thicken slightly.
Cooking the Tortilla
First Side
- In the same pan, heat 1–2 tablespoons of the reserved olive oil over medium heat.
- Pour the egg-potato-onion mixture into the pan and spread it out evenly with a spatula.
- Cook for 5–7 minutes until the bottom is set and the edges begin to pull away from the pan.
Flipping the Tortilla
- Place a large flat plate or lid over the pan.
- Carefully invert the pan so the tortilla lands on the plate, cooked-side up.
- Slide the tortilla back into the pan, uncooked side down.
- Cook for another 4–5 minutes until the tortilla is golden and fully set.
You can adjust the cooking time based on how runny or firm you prefer the center.
Serving the Spanish Tortilla
- Let it rest for 10 minutes before slicing.
- Cut into wedges for a main course or squares for tapas.
- Serve warm, at room temperature, or even cold—Spanish tortilla is delicious at any temperature.
Delicious Variations
While the classic recipe stands tall on its own, you can personalize your Spanish tortilla with flavorful additions:
With Red Pepper
Add sliced or diced red peppers while cooking the potatoes for color and sweetness.
With Chorizo
Incorporate small pieces of cooked Spanish chorizo for a bold, smoky flavor.
With Spinach
Stir in blanched or sautéed spinach into the egg mixture for a green twist.
With Cheese
Grate Manchego, cheddar, or even mozzarella into the eggs for a creamy, cheesy layer.
With Herbs
Add chopped parsley, chives, or thyme to enhance freshness.
Each of these additions gives the tortilla a unique flair while maintaining its essence.
Expert Tips for a Perfect Spanish Tortilla
- Use waxy potatoes like Yukon Gold—they hold their shape better and yield a creamier texture.
- Don’t rush the cooking of the potatoes and onions. Gentle heat draws out their sweetness and softens them without burning.
- Use enough olive oil to prevent sticking and to infuse the dish with rich flavor.
- Rest the egg mixture before cooking—it helps bind the tortilla and develop flavor.
- Flip with confidence. Use a large, flat plate that fully covers the pan and practice a quick, smooth flip.
Serving Suggestions
Spanish tortilla is incredibly versatile:
- Tapas: Cut into bite-size squares and serve with toothpicks and olives.
- Brunch: Pair with fresh tomato salad, crusty bread, and aioli.
- Dinner: Serve alongside a green salad or roasted vegetables.
- Snack: Enjoy cold with a drizzle of olive oil or a slice of jamón.
It’s a dish that fits seamlessly into any part of the day.
