In brief

History and origin

Castrovillari is the largest town on the Calabrian side of the Pollino and lies in a basin at the foot of the mountain. For centuries farming was its main resource: vegetables filled the fertile land near the streams, pulses the poorer plots. In this landscape the white onion took hold, a local ecotype of Allium cepa.

Until the 1970s so much was grown that it also supplied nearby towns in Calabria and Basilicata. The fair of Terranova da Sibari, still held on 13 June, Saint Anthony's day, was known as "the fair of the Castrovillari onions". ARSAC also recalls an old barter: shepherds from Terranova di Pollino came with donkeys loaded with cheese and traded it for onions halfway, in the mountains between Calabria and Basilicata, in the heart of today's national park.

Cultivation later shrank, and the seed has survived thanks to a few guardian growers. The Municipality has granted it a municipal designation (De.Co.), and Slow Food has made it a Presidium.

Area and method of production

The white onion was once grown on a few dozen hectares, from the districts near the town along the valley of the Coscile river down to part of the Sibari plain. Today the fields are mainly in the Jardìni, or Giardini, district, historically served by irrigation channels, where some twenty growers farm it on small plots.

Methods are low-impact, without synthetic chemicals, with crop rotation and, in some cases, manuring. The calendar follows handed-down customs: the seed is gathered on 16 July, feast of Our Lady of Mount Carmel; the seedbed, the pruvinu, is prepared by 5 August, preferably under a waning moon; transplanting takes place in early November.

Fresh onions are pulled from late February to May, while mature bulbs are harvested from early June to July. The guardian growers keep and hand down the seed, choosing each year the bulbs that will be used for reproduction.

How to recognise it

The bulb is white, with faint pink streaks on the outer skins, and can grow very large, sometimes over a kilo. It stands out for its sweetness and digestibility, qualities that make it well suited to eating raw.

ARSAC tests found pungency varying widely from sample to sample, depending on soil, climate, genotype and the way each grower selects the seed bulbs. Some lines are very mild, and on this basis ARSAC sees scope for conservative selection to make the population more uniform.

It is found fresh from February to May, as an onion for immediate use, while mature bulbs arrive in summer. Processed and dried, according to the Presidium, it is available all year round.

In the kitchen

Thanks to its sweetness the white onion of Castrovillari is mostly eaten raw, in salads and fresh side dishes. It also features in traditional Pollino dishes such as soups and omelettes.

A typical recipe is pane cotto, panicòttu: bread enriched with broth, crushed beans, extra virgin olive oil, salt and cheese, in which the onion is an essential ingredient. It is a farmhouse dish of the Pollino.

In recent years the onion has also entered the classroom: at the catering school in Castrovillari a seminar with ARSAC and the growers' association presented the product in its different processed and fresh forms, and students cooked new recipes based on the white onion.

Where to taste it

The white onion is best discovered in Castrovillari, the Calabrian gateway to the Pollino National Park. The fields of the Jardìni district lie right next to the town, and this is where the guardian growers keep the seed alive.

The dedicated event is the Festival della Cipolla Bianca di Castrovillari, which in 2025 reached its fourth edition, from 4 to 6 July, opening with a meeting of institutions, researchers, growers, teachers and food professionals on the value of the product. Down on the plain, the 13 June fair at Terranova da Sibari keeps the memory of when it was the onion fair.

The De.Co. recognition, ARSAC notes, strengthens the identity of the whole area between the Sibaritide and the Pollino, rich in nature, landscapes and archaeological sites: a trip through the park's mountains and nearby villages, from Morano Calabro to Civita, goes well with a taste of this sweet onion.
