Le Fontanelle
Cured meats · Contigliano (RI)
A family-run agriturismo and cured-meat workshop, Le Fontanelle processes the meat from its own farms in-house — from prosciutto to salame — which the Osteria serves in its boards and starters.
Territory
Seasonality and a bond with the land are at the heart of Osteria Antonelli's cooking: a menu built together with small producers from across Lazio, from the extra virgin olive oil of the Rieti Sabina to the regional wine list.

Buffalo mozzarella and dairy · Provincia di Rieti
An agricultural farm in the province of Rieti, La Gasperina supplies the buffalo mozzarella and dairy the Osteria brings to the table in its starters — part of the same short-supply-chain cheesemaking tradition as the Osteria's other local producers.

Organic extra virgin olive oil · Salisano (RI)
From the hills of the Rieti Sabina, Tenuta Rocca Baldesca produces the organic extra virgin olive oil the Osteria brings to the table with seasonal vegetables — a simple ingredient, but central to the Sabine identity of Marco and Gianmarco Antonelli's kitchen.

Eggs and seasonal vegetables · Contigliano (RI)
The farm L'Uovo del Campo, in Contigliano, supplies the Osteria's ultra-fresh eggs and seasonal vegetables — starring, among other things, in one of the house's signature dishes: the 62°C egg, served with Parmigiano Reggiano fonduta and local black truffle.

Fresh egg pasta · Rieti
The artisan pasta workshop Chitarra Antica, in the heart of Rieti, makes the fresh egg pasta the Osteria brings to the table in its first courses — from traditional shapes to seasonal fillings.

An outstanding interpreter of Aleatico, with labels like "Turan" and "Ramatico": an often-overlooked grape, given its due on the list as the ideal companion to the Osteria's desserts.

Wine · Acquapendente (VT)
A new addition to the Osteria's wine list: from the Trimeride line to the spontaneously-fermented Jazz series, Terre d'Aquesia brings several labels to the list across whites, reds and rosés.

A Rieti winery that accompanies the Osteria's list on several fronts: from sparkling wines (Strappo alla regola) to rosés (Bandolo della matassa) to dessert wines (Se Bo Be Bi).
