Marcella Hazan’s Barley Soup from Italy’s Trentino region transforms simple ingredients into something quietly extraordinary. Barley, potatoes, and carrots simmer until tender, while sautéed onions, prosciutto, rosemary, and parsley infuse the broth with savory depth. Finished with Parmigiano-Reggiano and black pepper, it’s hearty, comforting, and perfect for winter.
