Line a sheet pan with aluminum foil. Lay the bacon in a single layer on the foil. Try to keep the bacon from touching.
Put the bacon in a cold oven. Turn the oven on to 400 degrees F. Let the bacon cook for 12 minutes.
After 12 minutes, check the bacon every 1-2 minutes. Every oven cooks a little differently, so watch for hot spots (the bacon on one part of the pan will cook faster). The bacon can get overcooked very quickly, so it's important to watch it closely as it finishes cooking.
When the bacon is done, take it off the sheet pan and let it drain and cool on paper towels.
