Ingredients
Main Components:
- 350g potatoes (about 3 medium, preferably waxy varieties like Yukon Gold)
- 1 small onion (sweet or yellow onion works perfectly)
- 5 large eggs (room temperature for best results)
- 3 tablespoons cooking oil (olive oil preferred for authentic flavor)
- ½ teaspoon salt (or to taste)
Detailed Instructions
Preparation Phase
1.Prepare the potatoes: Peel and slice the potatoes into rounds about ¼-inch thick. The key is keeping them uniform so they cook evenly.
2.Soak for tenderness: Place the sliced potatoes in a bowl of cold water and let them soak for 10 minutes. This removes excess starch and helps prevent sticking while ensuring they cook through perfectly.
3.Prep the onion: Slice the onion into thin half-moons. Don't worry about perfect uniformity here – slight variations add character to the final dish.
4.Dry thoroughly: Drain the potatoes and pat them completely dry with paper towels. Any remaining moisture will cause dangerous oil splattering and prevent proper browning.
Cooking the Base
5.Combine vegetables: In a large bowl, gently mix the dried potato slices with the sliced onion. This ensures even distribution throughout the tortilla.
6.Start the magic: Heat your skillet over low heat and add the oil. The pan should be warm but not smoking – this gentle approach is crucial for the perfect texture.
7.Cook with patience: Add the potato-onion mixture to the skillet, spreading it evenly. Cook for 25-30 minutes, stirring gently every 5-7 minutes. You'll know it's ready when the potatoes are fork-tender and the onions are golden and sweet-smelling.
Creating the Tortilla
8.Prepare the eggs: While the vegetables finish cooking, crack the eggs into a large bowl and whisk them thoroughly. Add the salt and whisk again until completely combined.
9.The crucial mix: Remove the cooked potato-onion mixture from heat and immediately fold it into the beaten eggs. Mix gently but thoroughly – you want every piece coated but not mashed.
10.The final cook: Clean your skillet and return it to the stove over minimum heat. Add a little fresh oil to prevent sticking, then pour in the entire egg-vegetable mixture.
11.Shape and set: Use a spatula to spread the mixture evenly and flatten the top. Cover with a lid and cook for 20 minutes without lifting the lid – this creates the perfect steam environment.
12.The flip: Carefully flip the tortilla using a large plate (slide tortilla onto plate, flip skillet over plate, then slide back into pan). Cook the second side for 5 minutes uncovered.
Chef's Tips for Success
- Choose the right potatoes: Waxy varieties like Yukon Gold hold their shape better than russets, preventing your tortilla from becoming mushy
- Master the flip: If you're nervous about flipping, slide the tortilla onto a plate, place another plate on top, flip both plates, then slide back into the pan
- Temperature is everything: Keep heat low throughout the entire process – high heat will create a rubbery texture and uneven cooking
- Make it ahead: This tortilla actually improves in flavor after resting for 30 minutes to 2 hours, making it perfect for entertaining
- Test for doneness: The center should be just set but still slightly creamy – it will continue cooking from residual heat
Nutritional Benefits
Compared to heavy breakfast pastries or processed foods, this Spanish tortilla offers impressive nutritional value. High-quality protein from eggs supports muscle health and keeps you satisfied for hours. Complex carbohydrates from potatoes provide sustained energy without the crash of refined sugars. Heart-healthy monounsaturated fats from olive oil support cardiovascular health. Essential B vitamins from eggs boost brain function and energy metabolism.

Storage and Serving
Store leftover tortilla covered in the refrigerator for up to 4 days. This dish is traditionally served at room temperature or slightly warm, making it perfect for picnics or make-ahead meals. For best flavor, remove from refrigerator 30 minutes before serving. The tortilla can be reheated gently in a low oven if you prefer it warm, but avoid microwaving as it can make the texture rubbery.

FAQ Section
Q: Can I use different types of potatoes?
A: Yes, but waxy potatoes like Yukon Gold or fingerlings work best as they hold their shape. Avoid russets as they can become too starchy and fall apart.
Q: What if my tortilla breaks when I flip it?
A: Don't panic! Even broken tortillas taste amazing. For easier flipping, you can finish cooking under the broiler instead of flipping, or use two plates to help support the tortilla during the flip.
Q: Can I add other vegetables?
A: Absolutely! Red bell peppers, mushrooms, or even spinach make excellent additions. Just make sure to cook any additional vegetables until tender before mixing with the eggs.
Q: How do I know when the tortilla is fully cooked?
A: The center should be just set but still slightly creamy. Insert a knife into the center – it should come out with just a tiny bit of wet egg, as it will continue cooking from residual heat.
Q: Can I make this without a lid?
A: The lid helps create steam for even cooking, but you can cook uncovered if needed. Just watch carefully and reduce heat to prevent the bottom from burning before the top sets.
Q: Is this recipe suitable for meal prep?
A: Perfect for meal prep! The tortilla tastes great cold or at room temperature and keeps well for up to 4 days refrigerated. Cut into wedges for easy grab-and-go portions.
Q: What's the best pan size for this recipe?
A: A 9-10 inch non-stick or well-seasoned cast iron skillet works best. Too large and your tortilla will be thin; too small and it might not cook evenly.
Q: Can I make this dairy-free?
A: This recipe is naturally dairy-free! Just ensure your cooking oil is a plant-based variety like olive oil (which is traditional and recommended).
