Question: do you have to reheat cooked bacon?
Answer: Yes, when you have a lot to make, cooking bacon in advance is a good idea. I would cook the bacon just until it starts to get crisp. That way when it comes time to reheat it you can reheat it until it's just crisp. ... It's best to reheat the bacon in the oven or in the toaster oven if you're not reheating a lot.
