I'm assuming you are performing asynchronous code reviews (like pull request comments). If you have the time, one of my teams did occasional "Code Inspections", where a team of 5 people would review a larger chunk of functionality together. The key is that each person has an assigned responsibility, and that one of those is the "Reader". The reader presents the code for review, and the reader is NOT the author. The author is there, but I think it helps when someone else is presenting the code to reduce the feeling that the review is of the author.
