30 minutes was definitely not enough time to fully cook the regular-thickness chicken breast halves that I used. My first bite, I thought I'd bitten into a completely fatty portion. Back into the oven it went for 10 minutes, which still didn't do the trick. After an additional 15 minutes of baking (total 1 hour), the chicken was finally edible. Except that my appetite was completely squelched from that first bite I took. Besides that, the flavor was good. Might be a while before I'll try making it again, though.
