cooking time for chicken-pesto in the oven I love to make chicken stuffed with pesto. I cut the chicken breast in half, and then fill them with pesto and make a roll of it. 

I first bake the chicken in a frying pan to give them a nice color, and then put them in the oven to cook until it's done.

However here comes my problem, I want the chicken to be totally done, because I am very afraid to eat raw chicken. However, I now cook them too long to be sure it is not raw anymore. I cook them for at least 20 minutes on 175 degrees Celsius. 

I was wondering, can anybody tell me how long I should cook them in the oven on which temperature to be sure it is not raw anymore, but not cook them overdone?
There is no definitive time or temperature that would 100% guarantee your chicken was done without it having a 99% chance of being over cooked and dry.

It's quite hard to use a meat thermometer with stuffed chicken breasts but if your meat/filling has got up to 74°C in the center and there is no pink in the meat you'll be fine.
