Cooking Buffet-style Bacon
Restaurants--especially large scale catering and buffets--almost always bake bacon.

It is extremely effective, and very easy.

Lay the bacon out on rimmed sheet pans, in a single layer.  For extra crispiness, use a rack, but cleaning the racks is not fun.  

Bake at 350-400 F (I give a temperature range since you may be using the oven for other items) for approximately 20-30 minutes (depending on temperature, thickness of bacon, and desired level of crispiness).

If you didn't use a rack, remove the bacon to paper towels to soak up the excess grease.

The bacon will be very flat and very uniform, and can get very crispy.
