Mediterranean Chestnut Traditions: A Cultural Journey
The chestnut, that small brown nut, appears every autumn in markets and on the streets of many Mediterranean cities, bringing back memories of seasonal traditions and flavors. With its sweet and slightly smoky aroma when roasted, chestnuts transport us to moments of gathering around a fire or to street stalls that appear with the first chills. This nut has long been a staple in the diets of mountain and rural areas, and its popularity has endured thanks to its flavor and versatility in the kitchen.
Ancient History: How Chestnuts Shaped Mediterranean Culture
Chestnuts have a long history in the Mediterranean. It’s believed that the Romans spread chestnut cultivation from Asia Minor across southern Europe, as the tree thrived in mountainous soils and temperate climates. During the Middle Ages, chestnuts were essential for many rural communities, especially during times of scarcity. Their low cost and high nutritional value made them a staple food, often called “the bread of the poor” in areas where wheat did not thrive. Over time, the use of chestnuts evolved from survival to tradition, becoming a symbol of the colder seasons and a characteristic element of autumn and winter festivities across the Mediterranean.
Best Mediterranean Chestnut Regions: From Spain to Greece
The Mediterranean basin is home to some of the best chestnut-growing regions, each with unique varieties and qualities.
Spain: In Spain, the main chestnut-producing areas are Galicia, Asturias, Castilla y León, and Andalucía, particularly Málaga and the Sierra de Aracena in Huelva. In addition to enjoying chestnuts, in Málaga you can also try the famous espetos, a culinary tradition you shouldn’t miss.
Galicia is the largest producer, known for large, flavorful chestnuts that are exported to various European countries.
Italy: Italy is famous for its varieties of chestnuts and “marroni.” Tuscany, Piedmont, Liguria, and Emilia-Romagna are renowned for their high-quality chestnuts, many of which have Protected Designation of Origin (PDO) status. The “marrone di Cuneo” and Mugello chestnuts are especially prized.
France: In southern France, chestnuts of exceptional quality are grown. In Corsica and Provence, where chestnuts are an essential part of culinary culture, they even have their own PDO. In Corsica, this nut is used in many typical products.
Portugal: In northern Portugal, in Trás-os-Montes and Beira Interior, chestnuts are an important resource and a key ingredient in local gastronomy. Here, some of the oldest varieties are cultivated and valued for their flavor.
Greece: In Greece, chestnut groves are concentrated in mountainous areas like the Peloponnese, Macedonia, and Thessaly. Chestnuts are a popular winter food, and producing regions celebrate the harvest with local festivals.
Autumn Chestnut Festivals: Mediterranean Seasonal Traditions

Discover authentic autumn celebrations across the Mediterranean basin
Chestnuts hold a special place in Mediterranean autumn festivals. In Spain, the tradition of eating roasted chestnuts is linked to All Saints’ Day and La Castanyada in Catalonia, where this nut is associated with celebration and remembrance. In France, roasted chestnuts are a common sight in town squares during the colder months, while in Italy, autumn is filled with fairs and festivals dedicated to chestnuts, especially in rural areas. These roasted chestnut stalls, so common in Mediterranean cities and towns, bring a cozy atmosphere that accompanies the change of season. In many rural areas, families still gather to collect chestnuts and prepare them together, an activity that reinforces the bond between tradition and community.

Roasted: Perhaps the most traditional and popular method. Chestnuts are roasted directly over embers or in ovens, taking on a sweet and smoky flavor. This preparation is common at street stalls and outdoor celebrations.
Boiled: In soups and stews, chestnuts are boiled to achieve a soft texture. In the mountainous regions of Spain and Italy, they are part of traditional dishes and are often served with meats or vegetables.
Desserts: In France and Italy, the famous marron glacé is a delicacy, a candied chestnut requiring a delicate caramelization process. Chestnut purée is also popular in desserts like Mont Blanc.
Chestnut Flour: Used in breads, cakes, and cookies, especially in Italy, where the castagnaccio is a rustic cake made from chestnut flour, pine nuts, and rosemary.
