Oui, le papier d'aluminium peut être utilisé au four. It is a common practice to use aluminum foil when cooking or baking certain foods in the oven. Aluminum foil helps to distribute heat evenly, prevent food from sticking to the pan, and can be used to cover dishes to prevent them from drying out.

toutefois, there are a few important considerations to keep in mind when using aluminum foil in the oven:

1. Check the manufacturer’s instructions: Ensure that the specific brand of feuille d'aluminium you are using is labeled as safe for use in the oven. Some types of foil may not be suitable for high-heat applications.
2. Use as a lining or covering: Aluminum foil is typically used as a lining on baking sheets, des casseroles, or as a covering for dishes. It can help with easy cleanup and prevent food from sticking. Avoid using aluminum foil as a cooking vessel by itself, as it may not be able to withstand the weight or may tear.
3. Avoid direct contact with heating elements: If you’re using aluminum foil to cover a dish or wrap food, ensure that it doesn’t come into direct contact with heating elements such as the oven’s heating coils or burners. Direct contact can cause the foil to melt or catch fire.
4. Be cautious with acidic or salty foods: Aluminum foil may react with certain acidic or salty foods, les faisant se décomposer et potentiellement affecter le goût ou la qualité. Pour éviter cela, vous pouvez placer une couche de papier sulfurisé entre les aliments et le papier d'aluminium.

N'oubliez pas de toujours suivre les directives d'utilisation en toute sécurité et de consulter les instructions spécifiques fournies par le fabricant de la feuille d'aluminium que vous utilisez pour vous assurer qu'elle convient à une utilisation au four..
