When it comes to Spanish cuisine, few dishes are as universally loved as the tortilla de patatas, also known as the Spanish potato omelette. This dish, traditionally made with potatoes, eggs, and onions, is known for its simplicity, rich flavors, and versatility. In this guide, we’ll walk you through a step-by-step recipe to make the perfect tortilla cu cartofi, as it’s affectionately called by Romanian communities in Spain.

  • Simple Ingredients: Only four key ingredients—potatoes, onions, eggs, and olive oil.
  • Great for Any Meal: Enjoy it for breakfast, lunch, dinner, or as an appetizer.
  • Easy to Customize: Add extras like vegetables, tuna, or chicken for variety.

The beauty of a Spanish tortilla lies in its simplicity. Here’s what you’ll need:

  • Potatoes: 4-5 medium-sized potatoes for the right consistency.
  • Onion: 1 large onion, sliced for added flavor.
  • Eggs: 4-5 large eggs to bind everything together.
  • Olive Oil: Essential for the traditional taste and texture.
  • Salt and Pepper: To season the dish to taste.

Pro Tip: Choose a good-quality olive oil, as it enhances the flavor of the tortilla significantly.


  1. Peel and Slice the Potatoes: Start by peeling your potatoes. Once peeled, cut them in half lengthwise and then into thin slices. Thin slices help the potatoes cook evenly.
  2. Slice the Onion: Peel the onion and cut it into thin strips (julienne style).
  1. Add Olive Oil to the Pan: Pour a few tablespoons of olive oil into a non-stick frying pan. Add the sliced potatoes and onions.
  2. Cook Slowly: Fry the potatoes and onions at medium heat for 15 minutes, stirring occasionally to prevent sticking or burning.
  3. Check for Doneness: The potatoes should be tender but not falling apart. Once done, strain them to remove excess oil.

Suggestion: For a lighter version, you can cook the potatoes and onions with less oil, as some Romanian cooks do. Add a bit of water to help soften the potatoes without too much oil.

  1. Beat the Eggs: Crack the eggs into a large bowl, add salt and pepper to taste, and beat until well-mixed.
  2. Combine with Potatoes and Onions: Add the cooked and well-drained potatoes and onions to the beaten eggs. Stir until fully combined.

Optional Add-Ins: At this stage, you can add ingredients like diced vegetables, tuna, or cooked chicken to customize your tortilla.

  1. Heat the Pan: Add a little more olive oil to the pan and heat over medium.
  2. Pour the Mixture: Pour the egg, potato, and onion mixture into the pan, spreading it evenly.
  3. Cook on Medium Heat: Allow the tortilla to cook for about 6-7 minutes on one side. The edges should begin to set.
  1. Flip the Tortilla: Place a large plate over the pan, carefully flip the tortilla onto the plate, then slide it back into the pan to cook the other side.
  2. Cook for an Additional 5-6 Minutes: Let the tortilla cook for another 5-6 minutes on medium heat, allowing it to set completely.

A Spanish tortilla is highly versatile and can be served in various ways:

  • Serve Hot or Cold: Tortilla de patatas tastes great both hot and cold.
  • As a Main or Side Dish: Serve it with a side salad, crusty bread, or grilled vegetables.
  • Appetizer Option: Cut the tortilla into small wedges or cubes for an easy appetizer at gatherings.

Pairing Tip: Enjoy your tortilla with a simple green salad drizzled with olive oil and vinegar for a balanced, refreshing meal.


Opt for waxy potatoes over starchy ones, as they hold their shape better when cooked, making the tortilla firm but tender.

Cooking at medium heat ensures the potatoes cook evenly without burning. Avoid high heat, as it may cause the outside to brown too quickly, leaving the inside undercooked.

A high-quality non-stick frying pan will make flipping easier and reduce sticking, ensuring a beautiful, intact tortilla.

Flipping can be tricky! Make sure to cover the pan entirely with a plate, hold both securely, and quickly flip the pan upside down. Slide the tortilla back into the pan to finish cooking.

Safety Note: When flipping, use caution and wear oven mitts if necessary to prevent burns.


Though the traditional recipe calls for potatoes, eggs, and onions, there are endless ways to customize your tortilla:

  • Vegetarian Tortilla: Add bell peppers, zucchini, or spinach for extra color and nutrients.
  • Protein Boost: Incorporate cooked ham, tuna, or shredded chicken.
  • Cheesy Twist: Add a handful of shredded cheese for a richer flavor.

Experiment Tip: Start with the traditional recipe before experimenting to appreciate the authentic flavor.


Tortilla de patatas is a wholesome dish packed with essential nutrients:

  • Potatoes: A good source of fiber, vitamins B6 and C, and potassium.
  • Eggs: Provide high-quality protein, as well as essential vitamins like B12 and choline.
  • Olive Oil: Contains healthy monounsaturated fats, which are good for heart health.

This balanced combination of carbohydrates, protein, and healthy fats makes it a satisfying and nutritious choice for any time of day.


  • Yes! Tortilla de patatas is excellent when made in advance. It stores well in the fridge for 2-3 days and can be enjoyed cold or at room temperature.
  • To reheat, place the tortilla in a non-stick pan over low heat for a few minutes on each side, or microwave it briefly.
  • While it’s possible to freeze, the texture may change slightly. If you plan to freeze, wrap it tightly in plastic wrap and store it in an airtight container for up to a month. Thaw in the fridge before reheating.

The classic tortilla de patatas is more than just a dish; it’s a beloved part of Spanish cuisine. With simple ingredients and a straightforward process, this Spanish potato omelette can become a staple in any kitchen. It’s ideal for family meals, casual brunches, or even a packed lunch.
