Verdure al cartoccio is a traditional dish made by wrapping and cooking vegetables in parchment paper or aluminum foil (or both). Vegetables such as zucchini, carrots, green beans, spring onions, potatoes, or cauliflower are often used for this dish.
Once cut, they are wrapped in baking parchment and baked until tender. It's important to note that the more soft, watery vegetables will take less time to cook than the firm ones such as potatoes and carrots. The vegetables steam during the process, and all juices stay in the paper.
