Yes, you can use aluminum foil to make a roasting pan for vegetables or chicken. Simply create a foil pouch or wrap the food in foil, ensuring it's sealed well to retain heat and moisture. This method is often used for easy cleanup and can be effective for cooking in the oven or on the grill. However, be cautious with high heat as aluminum foil can melt at very high temperatures. Always follow safety guidelines and avoid direct contact with open flames or broil settings that may cause the foil to burn.
