Cook the bacon and then add diced onions to the bacon grease and sautee those down.
Shred the cheese and dice the cooked bacon. Whisk together the 10 eggs and 3/4 c. milk. When you layer the ingredients into your crockpot make the first layer your hash browns.
Top that with 1/3 of your bacon, 1/3 of your cheese, a spoon full of onions, seasonings, and 1/3 of your egg mixture.
Layer again this same way until you reach almost the top of your crockpot leaving some room at the very top. Put on low and cook for approximately 5 hours, check at about 4 if you want it to be a bit wetter in consistency.
