Using a large baking sheet that has a lip on it, spray it with a little cooking spray (probably not really necessary, but it makes for easier clean up) and line up the raw bacon slices, side by side, like this (my baking sheet cooked a 12 ounce package of bacon all at once.
Now, depending on how thick your bacon is and how hot your oven runs, it takes roughly 20-25 minutes at 375 degrees (I don't even pre-heat the oven) to bake the whole package at once!! No turning slices, no splattering in your oven, no bacon fat skin burns and no curly bacon....its magic!!
regular thickness sliced bacon (I've never timed the thick sliced stuff). It comes out absolutely perfectly flat and Picky-picky husband who is one of the strictest bacon critics that I've ever met, gave this bacon BOTH thumbs up and raved about what a great texture and taste it had.....well, blow me over!!
NOTE: If you like super crispy bacon, just leave it in for an extra minute.
