1. Bake chicken legs in the oven with tin foil, because there is a lot of oil in the chicken legs. If you roast chicken legs directly, it will probably cause the oil inside to overflow, which will make the inside of the baking tray greasy and very troublesome to clean. This can be avoided after using tin foil.

2. In addition, wrap the chicken legs in tin foil and bake them in the oven, which can better lock the umami flavor in the food. If you sprinkle seasoning on it, it can be more delicious, but generally it doesn't need to be wrapped too tightly, just leave a little space.

3. It is worth noting that it is best not to drop acidic seasoning into the tin foil to avoid chemical reactions that are harmful to health.
