Take the bread and put it in the pan break it up as needed to be able to feel each bottom then place a layer of cheese on top then place a second layer of bread and cheese then repeat tell you just a little lower than the top off the baking tray. This will normally be two to three layers. depending on the size of the pan
Mix up the eggs and milk and pour them over the top of the bread
Cook the bacon on the stovetop in a pan or you can cook it in the oven as well. Feel like I have a little bit better control pan so that is my preferred method.
Once it is cooked and crispy and cool enough to touch break a part the bacon on top once you have done this it is ready for the fridge
Place in the fridge and let sit overnight
In the morning before adding the last two ingredients pull the casserole out of there fridge and mix the milk and the soup and milk together then pour on the top and place it in the oven for 1.5 hours at 300 Fahrenheit
Pull out of the oven and serve
