Ingredients

• Potatoes: About 1.5 lbs (around 3 medium) starchy or all-purpose potatoes, like Russets or Yukon Golds. These types hold their shape well while becoming incredibly tender, perfect for soaking up flavor.
• Onion: 1 medium yellow onion, thinly sliced. The onion isn't just for flavor; it adds crucial moisture and sweetness, making your Spanish tortilla even more custardy.
• Eggs: 8 large eggs, at room temperature. Room-temp eggs mix more evenly and create a smoother, more cohesive omelet.
• Salt: To taste. Don't be shy! Proper seasoning throughout the cooking process is key for a flavorful egg tortilla.

Directions

1. Key Technique: Read This Before You Start
   1. Slice Thickness: Aim for very thin, uniform slices for both potatoes and onion—about 1/8-inch thick. This ensures even cooking and that tender texture. A mandoline makes this quick and consistent, but always use its safety guard!
   2. Oil Level & "Gentle Confit": Traditional Spanish tortilla isn't fried; the potatoes are gently cooked, or "confited," in a generous amount of olive oil. They should be mostly submerged and gently bubbling, not sizzling violently. This slow cooking makes them incredibly tender without browning.
   3. Doneness: Your preference! A "custardy" center means it's still slightly soft and jiggly. "Fully set" is firm all the way through. Resting after cooking helps it set further.
2. Step-by-Step: How to Make Tortilla Española
3. Slice the Potatoes and OnionUsing a sharp knife or a mandoline (with safety guard!), slice your potatoes and onion into uniform 1/8-inch thick rounds or half-moons. Consistency is key for even cooking.
4. Cook the Potatoes and Onion Low and Slow in Olive OilIn an 8-10 inch nonstick or well-seasoned carbon steel skillet (this size gives that authentic tapas bar thickness!), pour in enough olive oil to mostly submerge your potatoes and onions—about 3-4 cups. Heat the oil over medium-low heat. Add the sliced potatoes and onions, stirring gently to coat. The oil should be shimmering, and you should see gentle bubbling, not aggressive frying. Cook for 20-25 minutes, stirring every 5 minutes or so, until the potatoes are completely tender but not browned. They should break easily when pressed with a spoon.
5. Drain (and Save!) the OilPlace a fine-mesh strainer over a heat-safe bowl. Carefully pour the potato and onion mixture into the strainer, allowing all the oil to drain back into the bowl. Press gently on the potatoes to extract any excess oil. Set the drained potatoes and onions aside.
   1. Mini Callout: This infused olive oil is liquid gold! Let it cool, then store it in an airtight container in the fridge for up to a week. It's fantastic for sautéing vegetables, dressing salads, or dipping bread.
6. Beat and Season the EggsIn a large mixing bowl, crack your 8 room-temperature eggs. Whisk them vigorously until the yolks and whites are fully combined and slightly frothy. Season generously with salt. Remember, the potatoes aren't heavily salted during cooking, so the eggs need to carry the flavor!
7. Combine and Rest BrieflyAdd the warm, drained potatoes and onions to the beaten eggs. Stir well to ensure every piece is coated. Let the mixture rest for 5-10 minutes. This resting period allows the potatoes to absorb some of the egg mixture, leading to a more cohesive and tender Spanish tortilla.
8. Cook the First SideWipe out your skillet (the same one you used for potatoes) and add about 1-2 tablespoons of the reserved infused olive oil. Heat over medium-low heat until shimmering. Pour the egg and potato mixture into the hot skillet, spreading it evenly. Gently press down on the surface with a spatula to ensure a compact egg tortilla. Cook for 5-7 minutes, or until the edges are set and golden, and the center still looks a bit jiggly. Run a spatula around the edges to ensure it's not sticking.
9. Flip the Tortilla (Flip Confidence Box)This is the moment! Don't panic.
   1. Quick Checklist: Have a plate or lid significantly larger than your pan ready. Ensure the tortilla is fully loosened from the pan edges.
   2. The Flip Move: Place the large plate/lid firmly over the skillet. With one swift, confident motion, invert the pan onto the plate. Slide the partially cooked tortilla back into the pan, uncooked side down.
   3. If It Breaks: It happens! Don't fret. Just gently push the broken pieces back together with your spatula, shaping it back into a round. No one will know once it's sliced!
10. Cook the Second Side + Set Your CenterContinue cooking for another 3-5 minutes on medium-low heat. Use the sides of your spatula to gently shape the edges of the tortilla, giving it that classic round, thick profile.
    1. "Custardy Center" Cue: Cook until the outside is golden, but the center still feels slightly soft and yields gently when pressed.
    2. "Fully Set" Cue: Cook a bit longer until the center feels firm when pressed.
    Once cooked to your liking, slide the
11. Spanish omelette onto a clean plate. Let it rest for at least 10-15 minutes before slicing. Resting allows the internal heat to continue cooking the center and helps the tortilla set perfectly.
