This recipe transforms classic spaghetti into a savory baked pie, combining al dente pasta with a rich, custardy blend of milk, eggs, sharp Pecorino, and creamy Fontina cheeses. Generously seasoned with black pepper, it's baked until golden and set, offering a comforting and unique take on a pasta dish, with optional broccoli rabe for added depth and flavor.
1. Always freshly grate your Pecorino and Fontina. Pre-grated cheeses often contain anti-caking agents that hinder melting and affect texture. The sharpness of Pecorino and the creamy melt of Fontina are crucial.2. If including broccoli rabe, blanch it briefly in salted water and ensure it's thoroughly squeezed dry before mixing. This prevents a watery pie and tempers any bitterness.3. Cook the spaghetti to a firm al dente. It will continue to cook and absorb moisture in the oven, so slightly undercooked pasta is ideal to avoid a mushy texture.4. A critical step is allowing the pie to rest for 10-15 minutes after baking. This allows the internal custard to set properly, ensuring clean, intact slices.5. Don't skimp on freshly ground black pepper; it's a star flavor here.
