How to Make Spanish Tortilla

Name: How to Make Spanish Tortilla
Cuisine: spanish

This isn't a wrap or a flatbread. Spanish tortilla is a thick, round omelet that's more potato than egg, served at room temperature and cut into wedges like a pie.

Total time: 45 min
Hands-on: 30 min
Serves: 6
Difficulty: Intermediate

Before you start

The flip is the moment of truth

You'll need to flip a heavy, hot tortilla using a plate. Practice the motion once with an empty pan so your hands know what to do when it matters.

10-inch nonstick or well-seasoned cast iron pan
large plate for flipping
thin spatula

Ingredients

1½ lb Yukon potatoes, peeled and sliced ¼-inch thick
1 cup olive oil
1 medium yellow onion, sliced thin (optional)
6 large eggs
1 tsp salt

The confit method

Cook potatoes in olive oil until they surrender

The potatoes aren't fried — they're slowly cooked in oil until they're creamy inside and just beginning to break apart. This takes time but creates the tortilla's signature texture.

Step by step

Heat oil and cook potatoes. Heat olive oil in your pan over medium-low heat. Add potatoes and onion if using. Cook 15-20 minutes, stirring occasionally, until potatoes are tender enough to break with a spoon but still hold their shape mostly.
Drain and cool slightly. Strain potatoes through a fine mesh strainer, saving the oil. Let potatoes cool for 5 minutes — they should be warm, not scalding hot, when they meet the eggs.
Beat eggs and combine. Beat eggs with salt in a large bowl. Gently fold in the warm potatoes. The mixture should look more like potato salad with eggs binding it than scrambled eggs with potato bits.
Cook the tortilla. Heat 2 tablespoons of the reserved oil in your clean pan over low heat. Pour in the egg-potato mixture and cook 8-10 minutes until the bottom sets and the edges pull away slightly. The top should still be quite wet.
Flip with confidence. Run a spatula around the edges. Place a large plate face-down over the pan. In one swift motion, flip the pan over so the tortilla drops onto the plate. Slide it back into the pan, cooked side up.
Finish cooking. Cook another 3-5 minutes until the second side sets but the center still has a slight jiggle. Remove from heat and let cool to room temperature before cutting.

Tips & troubleshooting

Save the strained olive oil — it's potato-flavored gold for roasting vegetables
A properly made tortilla holds together when you pick up a wedge with your fingers
Room temperature is the traditional serving temperature, not hot from the pan
If your first flip fails, scramble it up and call it broken eggs with potatoes — still delicious

Variations

Tortilla without onion. Traditional tortilla española uses only potatoes and eggs. Skip the onion for pure potato flavor.
Tortilla with chorizo. Add ¼ cup diced Spanish chorizo when you add the potatoes to the oil.
Individual tortillas. Make small tortillas in a 6-inch pan using 2 eggs and ⅓ of the potato mixture per tortilla.

Questions

How do I know when the bottom is set enough to flip?: The edges will pull away from the pan sides slightly, and when you shake the pan gently, the tortilla should move as one piece, not slosh around.
What if I break it during the flip?: Slide the pieces back into the pan and cook as broken tortilla. It won't look perfect but will taste just as good.
Can I make this ahead?: Spanish tortilla is actually better after sitting for a few hours. Make it in the morning for dinner, or the night before for a picnic.
