Arrange the bacon slices on a sheet pan and place the pan on the center rack of a cold oven. (Try not to stretch the slices out. Just gently drape the bacon across the pan.) Close the oven door. Turn the oven on to 400°F. Walk away. Come back 17 to 20 minutes later. As soon as the bacon is golden brown, but not excessively crisp, it's done. The exact time will depend on the thickness of the bacon slices, and also on how quickly your oven reaches the target temperature. Remove the pan from the oven.
