i told you that you should have done it in my way.

2

The second is incorrect.

3

in the light of your statement,how to understand this correct sentence “she cooks chicken in the way i like” which is found in a dictionary.
“in…way” and “…way” confuse me

4

I would not use ‘in’ with that informal sentence:
She cooks chicken the way I like (it),
However if you found it in a dictionary then I will not argue that point. It makes no difference to the meaning.

Here ‘the way’ relates to the method of cooking and the resultant taste/texture. etc.
