Roasted Pumpkin Alfredo Fettuccine

The roasting process concentrates the natural starches, providing a thick body to the sauce without additional thickening agents. Onions and garlic sautéed in butter form the aromatic base, which is then blended with the squash and heavy cream for a uniform texture. Grated Parmigiano-Reggiano introduces a salty, nutty profile, while a small measure of ground nutmeg provides a warm complexity that balances the sweetness of the squash. The wide ribbons of fettuccine are chosen specifically to hold the heavy sauce effectively. For improved efficiency, the squash can be prepared a day in advance and stored in the refrigerator. Using a ladle of starchy pasta water during the blending stage allows for precise control over the final consistency. To finish the plate, sage leaves fried in brown butter offer a bitter herbal contrast to the squash. White pepper adds a subtle heat while preserving the bright orange color of the sauce. Butternut squash serves as a functional substitute if kabocha is unavailable.
