Olasagasti Preserves

At Bacalalo we have created this collection to group together all the canned goods from the Olasagasti brand , a family business with a long history located next to the fishing port of Ondárroa (Bizkaia) .

Since the end of the 19th century, Olasagasti has worked with species from the Cantabrian Sea such as Bonito del Norte, tuna, ventresca, mackerel or anchovies , respecting the season and taking care of every detail of the process: selection of the fish, manual cleaning, gentle cooking and packaging in top quality oils.

The result is preserves with an intense and natural flavor, designed for both everyday use and special occasions:

• Juicy and delicate tuna belly from Bonito del Norte
  
• Tuna in olive oil, ideal for salads and sandwiches
  
• Light tuna and bluefin tuna for heartier recipes
  

If you appreciate fresh market produce, tradition, and the authentic flavors of northern Spain, Olasagasti preserves are a sure bet. Create your own tapas, pair them with good bread, pickles, and white wines… and enjoy the Cantabrian Sea straight to your table.

Olasagasti canned goods originate near the port of Ondarroa, in Bizkaia, where the sea and fishing are an integral part of daily life. For generations, they have been preparing Cantabrian bonito, tuna belly, and mackerel using traditional methods, with meticulous control of salt levels and cooking times. The result is canned goods with an authentic taste of the sea and a distinctly northern character.

Olasagasti Bonito del Norte tuna is cleaned and hand-selected to obtain firm, juicy, white loins. The belly , the most tender part of the fish, is presented in thin flakes that melt in your mouth. These preserves are ideal to enjoy practically on their own, with good bread and a drizzle of olive oil.

In addition to bonito, Olasagasti works with high-quality tuna , caught in the best areas of the Cantabrian Sea and the North Atlantic. Each species is treated with respect for its natural timing and characteristics to maintain its unique texture and flavor. They are versatile options for salads, stews, sandwiches, and tapas.

At the factory in Bizkaia, a traditional process is followed: selection of fresh fish, gutting, gentle cooking, manual cleaning, and individual canning. This method allows for meticulous control over every detail and ensures that only the finest pieces reach the can. The result is uniform canned fish with a carefully crafted presentation and a stable shelf life.

Olasagasti canned fish is made with high-quality olive oil and natural ingredients , without artificial preservatives. The oil protects the fish, enhances its flavor, and makes it easier to digest. Therefore, using the oil from the can in your recipes (for dressings, mayonnaise, or toast) is a great way to enjoy the product to the fullest.

If you're looking for a canned fish to impress at appetizers, Bonito del Norte tuna belly is a sure bet. For everyday meals, bonito loins and Olasagasti tuna are perfect for salads, pasta, and quick main dishes. Mackerel is ideal for those seeking an oily fish with intense flavor and good value.

With just one can of Olasagasti, you can prepare bonito toasts with piparra peppers , warm potato and tuna belly salads, filling for piquillo peppers, or homemade empanadas. Canned goods allow you to put together impromptu dinners with very little effort: simply open, drain lightly, and combine with good vegetables, pickles, and crusty bread.

These preserves are perfect for a quick everyday snack or a special occasion. You can serve the bonito and tuna belly on tasting platters, alongside mild cheeses, olives, and a good white wine or txakoli. The canned format makes them easy to store in the pantry, ensuring you always have a gourmet option on hand.

Canned fish retains its nutritional properties and offers a long shelf life without needing refrigeration before opening. Having Olasagasti canned fish at home allows you to enjoy oily fish, rich in omega-3 fatty acids , anytime, without the hassle of cleaning, bones, or cooking time.

Olasagasti collaborates with fleets that use selective and responsible fishing methods , respecting minimum sizes and seasons. This philosophy helps protect the Cantabrian fish stocks and guarantee a sustainable long-term supply, without compromising the quality that characterizes the brand.

Store the cans in a cool, dry place away from direct sunlight . Once opened, keep the fish in the refrigerator in an airtight container covered with its own oil, and consume it within 2–3 days. To enjoy the best flavor, it is recommended to remove the can from the refrigerator a few minutes beforehand and serve it at a slightly chilled, not ice-cold, temperature.

At Bacalalo, we select Olasagasti products that best align with our commitment to market-fresh, gourmet-quality products . We offer a full range of bonito, tuna belly, and mackerel , delivered with care and expert advice if needed. This way, you can enjoy trusted canned goods at home, with the same quality you'd find in a fine fishmonger.
