Ingredients
- Olive oil (100 ml / ½ cup): Extra virgin olive oil provides rich flavor while gently cooking the potatoes and onions without frying.
- Onion (1, sliced): Thinly sliced sweet onion adds subtle sweetness and pairs perfectly with tender potatoes.
- Potatoes (450 g / 1 lb, peeled and thinly sliced): Yukon Gold or similar waxy potatoes ensure a tender, creamy interior when cooked slowly.
- Eggs (8 medium, preferably free-range): Fresh eggs bind the ingredients together and create a soft, fluffy texture.
- Sea salt: Enhances all flavors, seasoning the potatoes, onions, and egg mixture perfectly.
- Freshly ground black pepper: Adds a subtle spicy note that balances the richness of the dish.
Instructions
- Cook the Potatoes & Onion
-
Heat the olive oil in a large non-stick skillet over medium heat until shimmering. Add the thinly sliced potatoes and onions, seasoning lightly with salt and pepper. Cook gently for 15 to 20 minutes, stirring occasionally, allowing the potatoes to soften and slowly confit in the oil rather than frying harshly. This slow cooking process ensures the potatoes become tender and infused with subtle flavors without crisping up.
- Prepare the Egg Mixture
-
While the potatoes and onions cook, crack the eggs into a large bowl. Season with a pinch of salt and freshly ground pepper, then beat lightly until just combined. Adding cooked potatoes and onions to the eggs, carefully mix to coat everything evenly. Let this mixture rest for 5 minutes, allowing the flavors to meld and the potatoes to absorb the egg’s seasoning.
- Cook the Omelette
-
Return about one tablespoon of the reserved olive oil to the pan over medium heat. Pour the egg, potato, and onion mixture evenly into the skillet, spreading it out gently. Cook for 5 to 7 minutes, until the bottom turns a beautiful golden color and the egg is mostly set but still tender on top. This stage creates a perfect crust while retaining a creamy inside.
- Flip the Omelette
-
Place a large plate securely over the skillet’s opening and carefully invert the pan so the omelette slips onto the plate. Slide it back gently into the pan cooked side up. Cook for another 4 to 5 minutes until the second side sets firmly but remains slightly soft at the center, maintaining the classic creamy texture of a Spanish tortilla.
- Rest & Serve
-
Transfer the cooked omelette to a serving plate and let it rest for 5 to 10 minutes. This resting step helps the texture settle and flavors deepen. Serve warm or at room temperature, either as a fulfilling breakfast, light lunch, or a tapa with friends and family.
- Use moderate heat throughout to ensure slow cooking, which produces the classic creamy texture inside.
- Reserving and reusing olive oil enhances flavor for future recipes and contributions to overall dish richness.
- Flipping the omelette carefully is key — use a plate slightly larger than your skillet to avoid breakage.
Storage Tips
Store leftover Spanish omelette in an airtight container in the refrigerator for up to 3 days. It can be eaten cold or gently reheated on the stove or microwave, maintaining much of its creamy texture.
Serving Suggestions
Serve the Spanish omelette with a fresh garden salad and crusty bread for a light meal. It also pairs wonderfully with olives, roasted peppers, or a simple garlic aioli when served as tapas.
- Slice potatoes uniformly about 3mm thick for even cooking and optimal texture.
- For an authentic slightly runny center, reduce the final cooking time by 1 to 2 minutes, resulting in a custardy interior.
- Use a non-stick skillet to prevent sticking and ensure easier flipping of the omelette.
