I can't handle doing everything in one morning/day. I like to prep as much as I can.
When pre-cooked/cooked bacon is reheated, I'd like it to look like I just cooked it.
To keep bacon flat and not curl I bake on a silplat on a flat pan. Bake it 90 percent of the doneness you like, store wrapped in wax paper or baking paper or Saran, then a quick reheat in the oven for ten minutes before serving should do it.
