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.

When I prepare breakfast the night before, it’s another story. I can pop it in the oven and bake. No clean-up. No prep work. Easy peasy. I love it. 

This Overnight Bacon Breakfast Casserole is one of my family’s favorite breakfasts. I mean, what’s not to love about bacon and cheese. It’s comforting, delicious and fills you up for hours. I think it’s a yummy way to start your day and give you the energy to get whatever it is you need to do done.
