Tuna bottarga is a delicacy of Sicilian and Sardinian fishing tradition, made from salted, pressed, and aged tuna eggs.

In this comprehensive guide updated for 2026, you will discover what tuna bottarga is, how it is made, its nutritional values, how to use it in cooking, the best recipes, and where to buy high-quality artisanal bottarga.
What is tuna bottarga?
Tuna bottarga is the ovarian sac (roe sac) of bluefin or yellowfin tuna, subjected to a process of salting, pressing, and aging that can last from 2 to 6 months. The result is a compact product with a dark amber color, a semi-firm texture, and an intensely marine, savory, and slightly bitter taste.
In Sicily, bottarga production is an art passed down through generations, with the most renowned centers in Favignana, San Vito Lo Capo, and the Egadi Islands. Unlike mullet bottarga (more common in Sardinia), tuna bottarga has a stronger flavor and a softer grain.
How artisanal bottarga is made
The production of bottarga follows a traditional process unchanged for centuries:
- Extraction: the ovarian sacs are carefully removed whole from freshly caught tuna to avoid breaking them.
- Salting: the roe sacs are covered with coarse sea salt and left to rest for several hours.
- Pressing: weights are applied to remove residual moisture and achieve the characteristic flat shape.
- Aging: the product is hung in ventilated rooms and left to age for 2-6 months, during which it develops its unique flavor.

How do you eat tuna bottarga?
Bottarga is an ingredient best enjoyed raw or just lightly warmed. Excessive heat compromises its delicate flavor and texture. Here are the best ways to appreciate it:
- Grated on pasta: the most classic way, a generous sprinkle on spaghetti with garlic, oil, and chili pepper.
- In thin slices: cut with a sharp knife and served on bruschetta with a drizzle of oil.
- As a seasoning: sprinkled on risottos, salads, fish carpaccios, grilled vegetables, or eggs.
Tip: if the bottarga is too soft to grate, put it in the freezer for 15-20 minutes before using. To reduce saltiness, drizzle the slices with a few drops of lemon juice.
