There are dishes that are part of our collective memory. The potato omelet is one of them. Few recipes in Spanish cuisine evoke such unanimity, and yet, there are many ways to interpret it. Some more traditional, others more innovative. But if there's one version capable of winning over both purists and the most gourmet palates, it's undoubtedly the potato omelet with black truffle .
In this article, we'll explore this delicious combination in depth. We'll discuss how black truffle transforms a simple dish like the Spanish omelet into a sophisticated culinary experience, the perfect balance between tradition and innovation, how to prepare it step by step, and, of course, how to choose and properly store your black truffle to get the most out of it. This comprehensive guide is designed for both those new to this ingredient and those who already know that the aroma of Tuber melanosporum can change everything.
An omelet with history, aroma and depth
The potato omelet, also known as the Spanish omelet, is a recipe that needs no introduction. Its origins date back several centuries, and over time, it has evolved from a humble dish to a national symbol. But even great classics can be reinterpreted. Adding fresh black truffle to this preparation not only preserves its essence but enhances it.
The truffle doesn't change the nature of the dish. What it does is add a new aromatic dimension. A depth that doesn't compete with the softness of the egg or the texture of the potato, but rather envelops them. That's why the tortilla with black truffle has won over not only chefs, but also those who cook at home and want to surprise their guests with a unique touch.

Why does black truffle go so well with tortilla?
The black truffle (Tuber melanosporum) is characterized by a complex, earthy aroma with notes reminiscent of a damp forest, nuts, and a certain mineral sweetness. This aromatic profile intensifies when it comes into contact with fatty or umami-rich ingredients. Eggs are one such ingredient. In fact, one of the most effective ways to infuse food with truffle is simply to store them together. The pores of the eggshell readily absorb the truffle's aroma, even without them touching.
For this reason, the Spanish omelet—which is based on egg, potato, and, in many cases, onion—is an ideal canvas for black truffle to express itself. There's no need for complicated techniques or exotic ingredients. With good quality ingredients and respect for cooking times and temperatures, the result can be simply spectacular.

What type of truffle to use in your omelet
To achieve a deep and authentic flavor, the best option is undoubtedly to use fresh black truffles at their peak ripeness. We're referring to Tuber melanosporum , also known as the winter black truffle, which is harvested between November and March. This variety has the most intense aroma and provides the most elegant and balanced result.
It's important not to confuse it with Tuber aestivum , or summer truffle, which has a milder and less persistent aroma. Although it can also be used, the result won't be as striking.
In our shop you can buy fresh black truffles, hand-picked at their peak ripeness, perfect for recipes like this one. And if you're looking for an alternative to have on hand out of season, we also offer preserved and frozen truffles, with all their aroma perfectly preserved.
When should you add the truffle to the omelet? Before, during, or after?
There are different ways to incorporate truffle into a potato omelet, and all of them can be valid depending on the desired result.
A very effective technique is to flavor the eggs before using them , simply by storing them for 48 hours in an airtight container with the truffle. This way, even if the truffle isn't used directly in the mixture, some of its aroma will have already been transferred to the inside of the egg.
You can also grate fresh black truffle directly onto the beaten egg mixture and let it sit for a few minutes before cooking the omelet . This allows the aroma to be evenly distributed and present in every bite.
Another option, increasingly used in restaurants, is to shave the truffle over the cooked tortilla , just before serving. The residual heat will cause the truffle to release its essential oils and perfume the entire dish.
For special occasions, the ideal is to combine all three methods : flavor the eggs beforehand, incorporate truffle into the batter, and shave a small amount on top when plating. The result is an omelet with a lingering aroma, elegant and absolutely addictive.
Recipe: Potato omelet with black truffle step by step
Below, we explain how to prepare a classic truffled potato omelet , designed for four people. The proportions and cooking times can be adjusted to personal preferences, but this base recipe is a perfect starting point.
The ingredients you will need are the following: quality potatoes, fresh eggs, extra virgin olive oil, salt, and fresh black truffle Tuber melanosporum.
The preparation begins by peeling and thinly slicing the potatoes. These are then fried in plenty of olive oil over medium heat until tender and lightly golden. Meanwhile, the eggs are beaten in a large bowl, and if they have been previously flavored with truffle, they will already have that characteristic truffle touch.
Once the potatoes are drained, add them to the beaten egg and mix gently. At this point, you can grate a small amount of fresh black truffle , which will blend perfectly into the mixture. Let it rest for a few minutes to allow the aromas to infuse.
The tortilla is cooked in a non-stick pan with a little oil, according to the desired level of doneness. As soon as the outer crust has formed, it is carefully flipped and cooked briefly on the other side. Truffles benefit from short cooking times: the less time they are exposed to direct heat, the better they will retain their aromatic profile.
Before serving, you can add a few very thin slices of fresh black truffle on top. This not only enhances the dish's appearance but also immediately intensifies its aroma.
Variations for the most creative
Although the traditional recipe with potato and egg doesn't need much more, some people dare to take it a step further. Adding slowly caramelized onions , using purple or Galician potatoes , or even replacing part of the egg with heavy cream for a creamier result are some of the possibilities.
Some prepare individual baked versions, mini tortillas for canapés, or even reinterpretations in a glass, with a deconstructed tortilla and a potato foam. The important thing is that, whatever the format, the black truffle doesn't get lost or hidden, but rather shines with its own light.

How to preserve truffles before and after the recipe
Once you've bought your black truffle, proper storage is key to enjoying its full aroma. Ideally, keep it in an airtight container in the refrigerator, wrapped in absorbent paper that is changed every two days. If you're not going to use it within 7 to 10 days, you can freeze it whole or sliced, although it's best to consume it as soon as possible.
