Overnight Bacon Breakfast Casserole

I am a huge fan of the overnight breakfast casserole. In the mornings, I never feel like making a big breakfast. We’ll usually have toast or cereal. It’s a special occasion when I make bacon and eggs. I think it’s because my to-do list is long and I don’t feel I have the time to spend in the kitchen making a fancy breakfast.
