I would put them in for 30 minutes and then check to make sure they're cooked through. I always overcook chicken, too. I'm so paranoid about salmonella that I overcompensate when cooking!

I do mine at 375 for 20mins and check, then tent with foil for 10mins. They will continue to cook after you take them out of the oven b/c of the residual heat. If they're super thick breasts I either pound them thinner or butterfly them before cooking.
