Munich – September 11, 2026 -- Italian restaurant chain L'Osteria is putting fresh black truffle on its pizza menu for the first time, launching the dish as part of a limited-time "Mamma Mia" promotion running September 12 to 20.
The Pizza Tartufo, topped with freshly shaved black truffle, costs 11.95 euros in participating restaurants across Germany, Austria, the Netherlands and France. The same pizza is priced at 345 Czech koruna in the Czech Republic and 22.90 Swiss francs in Switzerland. Availability is limited to stock on hand.
Truffle moves from fine dining to casual pizza tables
John Schlüter, CMO of L'Osteria, said truffle is typically associated with white tablecloths and multi-course tasting menus. He said the chain wanted to bring freshly shaved black truffle to its pizzas without turning it into something complicated, aiming instead to give guests an accessible special moment.
Black truffle carries earthy, nutty and slightly spicy aromas that develop on warm dishes, which is why it's traditionally shaved fresh over pasta, risotto, eggs or pizza just before serving rather than cooked into the dish.
Diners can add a glass of Franciacorta for 6 euros
The chain is offering a 0.1-liter pour of Franciacorta sparkling wine for 6.00 euros as an add-on, available only alongside a Pizza Tartufo order.
Reality TV star Leyla Heiter fronts the campaign
L'Osteria has enlisted influencer and reality TV personality Leyla Heiter as the face of the Mamma Mia week. Heiter described the pizza as an affordable version of luxury, saying she doesn't need to travel to Dubai to feel indulgent when fresh truffle on pizza is available for 11.95 euros.
Mamma Mia joins a second recurring promotion in February
L'Osteria plans to run two themed promotional weeks annually going forward: "Festa dell'Amore" in February and "Mamma Mia" in September, both built around short-term specialty items rather than permanent menu additions.
