Tortello alla Lastra

Tortello alla Lastra is a traditional pasta dish from the Apennine mountains of Italy, particularly associated with the village of Bilegno in Emilia-Romagna. Its name derives from the method of cooking: "alla lastra" means "on a slab" – the filled pasta is cooked on a hot stone or metal griddle, rather than boiled. This technique gives the tortello a unique texture: crispy and toasted on the outside, with a soft, molten interior.

Key ingredients for the dough typically include flour, water, and sometimes eggs. The filling is a simple but essential combination of potatoes, Swiss chard, ricotta, and Parmigiano-Reggiano, seasoned with nutmeg. Some variations incorporate herbs like marjoram or even a touch of garlic.

What distinguishes a great version is the balance of textures and flavors: the dough must be thin enough to crisp without burning, the filling creamy and well-seasoned, and the cooking surface sufficiently hot to create an even golden crust. The dish is often served with melted butter and sage, or simply with a drizzle of local olive oil.

Regional variations exist across the Apennines; in some areas, the filling may include pumpkin or mushrooms, while the cooking stone might be replaced by a cast-iron pan. In Bilegno, the venue La Palta, praised by Francesco Zini, is known for its authentic preparation, keeping the tradition alive. The dish is a celebration of humble, local ingredients transformed by a unique cooking method.
