This recipe creates comforting spinach and mushroom stuffed shells. Jumbo pasta shells are filled with a rich blend of sautéed mushrooms, wilted spinach, ricotta, mozzarella, Parmesan, and pine nuts. These savory-stuffed shells are then nestled in a skillet with warm vodka sauce, topped with more cheese, and simmered until bubbling and golden, offering a delightful vegetarian main course.
Ensure pasta shells are cooked truly al dente; they will finish cooking in the sauce and you want them to hold their shape without becoming mushy. Rinsing them under cold water immediately after draining is crucial to stop residual cooking and prevent sticking. When sautéing mushrooms and shallots, allow them to properly brown without overcrowding the pan to develop deep umami flavor. For the filling, toast the pine nuts beforehand to enhance their nutty aroma. Don't overstuff the shells, as the cheese will expand slightly. Finally, heating the sauce in the skillet before adding the shells ensures an even distribution of heat for bubbling cheese without overcooking the pasta.
