Ingredients

Instructions

  1. Step 1: Peel and thinly slice 3 medium potatoes into 1/8-inch thick rounds and thinly slice 1 medium onion. Rinse potatoes under cold water to remove excess starch and pat dry.
  2. Step 2: Heat 1/2 cup olive oil in a large nonstick skillet over medium heat. Add sliced potatoes and onions with 1 tsp salt and 1/2 tsp black pepper, cooking gently for about 15 minutes, stirring occasionally, until potatoes are tender but not browned.
  3. Step 3: In a large bowl, whisk 6 large eggs until frothy. Drain excess oil from the skillet into a heatproof bowl, reserving about 2 tbsp oil.
  4. Step 4: Add the cooked potatoes and onions to the eggs and gently fold to combine without breaking the potato slices.
  5. Step 5: Heat the reserved 2 tbsp olive oil in the skillet over medium heat. Pour in the egg mixture and cook for 5-7 minutes until edges are set and bottom is golden.
  6. Step 6: Place a large plate over the skillet, carefully flip the tortilla onto the plate, then slide it back into the skillet to cook the other side for 4-5 minutes until fully set and golden.
  7. Step 7: Slide the tortilla onto a serving plate and let rest for 5 minutes before slicing into wedges.

How do I store leftover Pan-Fried Spanish Tortilla de Patatas?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat in the microwave or oven; egg- or grain-based items may need a splash of milk or water to refresh texture. Cold-served items (overnight oats, smoothies) keep 2–3 days in the fridge.

Can I substitute ingredients in Pan-Fried Spanish Tortilla de Patatas?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Pan-Fried Spanish Tortilla de Patatas for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
