How to Cook Bacon in the Oven

4. Don't forget to preheat your oven

If you're ready to try cooking bacon in your oven, the first step is to preheat the oven to around 400 degrees Fahrenheit. Since it can take a little while for some ovens to heat up to that temperature, don't forget to preheat as your first step. If you turn on your oven before you start prepping your pan, everything should be ready to go once you have your strips laid out. This is even more convenient when cooking another item in the oven like cinnamon rolls or a delicious French toast casserole.
