The trick is to put the pan in a cold oven and then switch it on and begin your timer. Im amazed how many people dont know this. Cook bacon in the oven. Cover cookie sheet with tinfoil first. We do 375 for about 20 min instead of 400 for ten because the lower and slower the more fat renders out. I hate getting SPLATTERED!! This works perfect! 8/25/12 – This is the easiest way to cook bacon ever! No more standing over a skillet for me! Clean up was easy!
