Truffled Cauliflower Gratin is a rich and indulgent side dish that combines the earthy flavors of truffle and cauliflower. The cauliflower is cooked until tender and then smothered in a creamy truffle-infused sauce. Topped with a crispy breadcrumb and Parmesan cheese crust, this gratin is baked until golden and bubbling. The result is a decadent and flavorful dish that pairs perfectly with roasted meats or can be enjoyed on its own as a vegetarian main course.
