How to make Spanish Tortilla
To prepare a Spanish Tortilla, start by melting butter and olive oil in a non-stick frying pan. The choice of fats is key, as they not only impart flavor but also help achieve that beautifully textured tortilla. Thinly sliced onions are cooked slowly, which draws out their natural sweetness and enhances the dish’s overall taste. The addition of waxy potatoes cut into very thin rounds allows them to cook evenly and retain their shape without breaking apart.
Once the onions and potatoes have cooked to a perfect tender state, the beaten eggs are seasoned and poured over the mixture, forming a luscious coating that binds everything together. The tortilla is then gently cooked on low heat to ensure that it sets evenly and becomes a golden masterpiece. Mastering the turning technique—flipping the tortilla to cook both sides—adds a fun twist to the process and completes the dish. It’s a wonderful recipe that, while appearing minimalist, offers an enriching culinary experience.
Ingredients
- 30 g butter
- 3 tablespoons olive oil
- 2 medium onions, thinly sliced
- 400 g waxy potatoes, cut into very thin rounds
- 6 large eggs, lightly beaten
- Salt, to taste
- Black pepper, to taste
Directions
- Heat the butter and olive oil in a 23 cm non-stick frying pan over medium-low heat. Add the sliced onions and cook for about 10 minutes, until soft and tender.
- Stir in the potato slices so they are well coated with the fat. Cover the pan and cook for around 20 minutes, stirring now and then, until the potatoes are tender without breaking them up too much.
- Season the beaten eggs with salt and pepper. Once the potatoes are cooked, pour the eggs evenly into the pan over the onion and potatoes, then cover again. Cook on low to medium-low heat for about 20 minutes, until the base is golden and the top is mostly set.
- Carefully turn the tortilla out onto a plate, then slide it back into the pan to cook the other side. Cook for about 5 more minutes, until fully set and lightly browned. Cut into wedges and serve.

How to serve Spanish Tortilla
Spanish Tortilla can be served in various ways, making it a true crowd-pleaser. Traditionally, it is cut into wedges and enjoyed either warm or at room temperature, allowing its flavors to shine. It can be accompanied by a fresh salad or some crusty bread, making for a delightful light lunch or snack. In tapas bars across Spain, it is often presented in smaller portions alongside other traditional dishes, creating a wonderful spread for sharing.
Additionally, you might consider garnishing the tortilla with fresh herbs like parsley or chives, or even a dollop of homemade aioli for a flavor boost. It serves as an excellent addition to brunch menus, catering to both savory and sweet palates when served with fruits and pastries alongside. Spanish Tortilla is also a great option for picnics or potlucks, due to its flexibility in being served cold or reheated.
How to store Spanish Tortilla
Proper storage is essential to maintain the integrity and flavor of your Spanish Tortilla. If you have any leftovers, allow the tortilla to cool completely before placing it in an airtight container. This will help prevent excess moisture from compiling, which can lead to changes in texture. Properly stored in the refrigerator, your tortilla can last for up to three days.
To reheat, simply warm slices in a non-stick frying pan over low heat, turning occasionally, until heated through. Alternatively, you can microwave individual servings if you’re short on time, though the stovetop method may yield a better texture. It’s worth noting that Spanish Tortilla is also delicious served cold, making it a perfect option for meal prep!
Tips to make Spanish Tortilla
Creating the perfect Spanish Tortilla can sometimes require a little finesse, so here are some helpful tips to elevate your dish. Ensure that your potatoes are cut uniformly thin; this will help them cook evenly and maintain their shape. The choice of potatoes is also crucial—waxy potatoes hold their structure and create a desirable texture, while starchy ones tend to break down too easily.
When it comes to egg seasoning, don’t be shy! Adequately salting and peppering your mixture ensures a flavor-rich outcome. Cooking on low heat may take longer, but it results in a beautifully set tortilla that isn’t burnt on the outside and remains creamy within. Remember to use a non-stick pan to prevent sticking and tearing when flipping. Lastly, practice your flipping technique, whether it’s using a plate or just a confident hand—getting that perfect golden finish takes a bit of confidence and practice.
