Cooking bacon in the oven eliminates the hassle of constant monitoring or having to tend to burns resulting from splattering grease. Simply arrange bacon strips on a lined baking sheet and slide them into the oven to cook until they reach your desired crispness, no preheating required. An added bonus is that cleaning up afterwards is a breeze; carefully remove the liner and toss it, leaving behind a nearly grease-free baking sheet.
Line a baking sheet with parchment paper or aluminum foil and arrange the strips of bacon in a single layer on top of the liner. Parchment paper and aluminum foil produce the same results, so use whichever you have on hand. A liner is not necessary -- it just makes clean up easier -- so if you don't have one handy simply put the bacon directly on the baking sheet. Choose a baking sheet with sides to prevent the bacon grease from dripping into your oven.
If you prefer crispy bacon, nestle a rack on top of the baking sheet and line the rack with strips of bacon. This allows the heat to circulate evenly, producing even, crisp results.
You can fit about a pound of bacon on a baking sheet, making the oven ideal for preparing a large quantity.
Put the baking sheet in the oven and set the temperature to 400 degrees Fahrenheit; preheating is not required. Set the temperature of a convection oven to 350 degrees Fahrenheit, which cooks foods faster than conventional ovens.
Cooking times vary depending on the type of oven, the thickness of the strips and how crispy you like your bacon. On average, bacon takes about 15 to 20 minutes to cook from the time you put it in a non-preheated oven, though you should check the progress after 10 to 12 minutes. You may need to remove the pan midway and drain off excessive amounts of bacon grease to reduce splattering. You don't have to flip the strips, though it's recommended for thicker cuts to ensure even cooking.
Remove the pan from the oven and, using a pair of tongs, transfer the bacon strips onto paper towels to remove excess grease and cool.
To clean up, remove the liner from the pan and toss it in the trash; however, to avoid spills, let the grease cool and set before you do this. You may see some grease on the sheet that seeped under the liner, but it shouldn't be much.
Another advantage to cooking bacon in the oven is that it produces bacon grease free of char, which is great for cooking. Let the pan cool slightly, and while the grease is still liquid, carefully pick up the liner and funnel it into a storage container. Refrigerate until needed.
