20 minutes is about the same about of time it takes to fry it in a pan. I know it seems faster but really it’s not. BY the time you’ve turned on the oven, then started to line the pan with tin foil and put the bacon on it the oven should be hot. Really I think the cooking time is the same and the best part is hot grease is not flying everywhere and burning you.
You’re right. I always use this method. It cooks evenly and you can do other things while the bacon is in the oven instead of standing over it turning it so it doesn’t burn.
