I'm going to be marinading them in some store bought marinade, and then bake them. I've been seeing bake times as varied as 10 minutes and 1 hour on the internet, and I'm not sure what to believe. I've never baked chicken breasts before (in fact, this is my first time doing anything with chicken that wasn't just frying them) and I have no idea at time at all. Any suggestions ? I was thinking of baking at 375 F. Alternate temperatures would also be welcome.
