Canederli al radicchio are traditional dumplings originating from Trentino-Alto Adige. These dumplings are usually made with a combination of stale bread with the crust removed, milk, shallots, olive oil, Treviso radicchio, salt, pepper, eggs, speck, nutmeg, flour, breadcrumbs, butter, and Parmigiano-Reggiano.

The ingredients are formed into tight balls that are boiled in salted water and simmered until heated through. These radicchio-enriched dumplings are traditionally served with melted butter and grated Parmigiano-Reggiano on top. It's recommended to serve the dish in shallow serving bowls.
