This easy sheet pan recipe combines pillowy gnocchi with fresh asparagus, bell peppers, and red onion, all roasted to perfection with a vibrant pesto coating. Finished with juicy cherry tomatoes, savory Parmesan, sweet balsamic glaze, and fragrant basil, it's a quick and flavorful vegetarian meal ideal for a weeknight.
For optimal crispiness, ensure the gnocchi and vegetables are spread in a single layer on the sheet pan; overcrowding will steam rather than roast them. Adding the cherry tomatoes in the second half of cooking prevents them from becoming mushy and allows them to burst slightly, releasing their juices without overcooking. A high oven temperature is crucial for achieving that desirable golden-brown exterior on the gnocchi and tender-crisp vegetables. Feel free to adjust the amount of pesto and balsamic glaze to your taste, and consider adding a squeeze of fresh lemon juice at the end for brightness.
