I've seen it on pintrest and my sil says she prefers it from the oven. Since I'm making blt grilled cheese sandwiches tonight I figure I'll give it a try.
It seems fairly simple to do. Have a cookie sheet lined with goil. Place bacon n foil (make sure jo are touching or over lapped). Bake for 15-20 minutes in a preheated oven at 375 degrees. If the bacon is thick you'll have to drain it half way through.
I've been doing it this way for years. Lots more grease bakes out. I've tried doing it on a rack, but then the bacon often sticks to it and that's a mess, and it's really hard to clean the rack. By putting it on a foil lined pan or a parchment paper, it's easy cleanup.
