Prepare this Make Ahead Sausage Sourdough Breakfast Casserole at night and bake it the next morning for a quick and easy holiday!

This easy overnight breakfast casserole recipe is made ahead of time and baked in the morning. It’s loaded with sausage, eggs, sourdough bread and a mix of pepper jack and cheddar cheese, which makes for a delicious breakfast or brunch anytime. But, it’s absolutely perfect for for the holidays. And friends, the holidays will be here before you know it!

We never make a big deal out of breakfast for Thanksgiving or Christmas. I usually serve homemade cinnamon rolls and nut rolls, which aren’t exactly easy to make, but because you make them in advance, there’s no cooking breakfast on the actual holiday.

Personally, I prefer savory breakfasts over sweet, and while I’d never pass up a homemade cinnamon roll, I like having something savory and a little more substantial to go with it. And, now that the kids are getting older, they like breakfast  casseroles for Thanksgiving and Christmas as much as I do!

I made a Lemon Blueberry Bagel Breakfast Casserole for Easter, so I wanted to make a different make ahead breakfast casserole for Thanksgiving and Christmas. I found this cheesy sausage and egg breakfast bake in my mom’s old recipe stash, and I couldn’t wait to make it!

This is a basic breakfast casserole recipe, but the possibilities for jazzing it up are endless. The original recipe called for plain bread, but I used sourdough, instead. I also added a mix of cheddar and pepper jack cheese instead of only cheddar.

Making this sausage sourdough breakfast casserole is super easy, and you can throw it together late at night like I did! All you do is

  1. Cook the sausage
  2. Cut up the bread
  3. Whisk the egg mixture
  4. Layer all the ingredients in a baking dish
  5. Refrigerate and bake in the morning

Easy peasy. The next time I make this sausage and egg breakfast casserole, I want to experiment with different flavors and, maybe, throw in some potatoes for an even heartier dish. I might even add some bell peppers and green chiles for a more Southwestern vibe. There really are no rules here, folks!
