Overnight Breakfast Casserole

Overnight Breakfast Casserole with Smoked Sausage & Hash Browns at The Happy Housewife

By contributing writer Beth

I’ve always loved night time, and so mornings aren’t really my brightest moments in life. I love to sleep in. So when we have overnight guests, I try extra hard to prep everything for breakfast in advance. Nobody wants to stay at someone’s house and have to wait until noon to get a bite to eat, right? So this overnight breakfast casserole was really a great solution for our family!

It’s hearty and feeds a huge crowd. It’s mild enough for the kids and a good foundation for parents to get creative. Here are some ideas for toppings that will let your guests customize their breakfast:

  • Sour Cream (or we always sub with plain Greek yogurt)
  • Salsa
  • Hot Sauce
  • Crushed Red Pepper
  • More cheese (Okay, this is pretty much my motto. “You can’t have too much cheese!”)

Plus, this is a perfect overnight casserole to serve on Christmas morning, since all the work is done the night before and you just have to pop it into the oven after presents are opened!
