Sausage and Egg Breakfast Casserole with Sourdough

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 and easy breakfast or brunch anytime. But, this sausage egg casserole is absolutely perfect for for the holidays. And friends, the holidays will be here before you know it!

I found this easy recipe for cheesy sausage casserole with bread in my mom’s old recipe stash years ago, and we’ve been making it for Thanksgiving and Christmas breakfast ever since then.

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

What You’ll Need

Here’s everything you will need to make the casserole. Full amounts are listed in the printable recipe card below.

• Breakfast sausage — I use ground sausage, but you can also use links and cut them into slices. Either pork or turkey sausage will work.
• Eggs — use large, not extra large for best results
• Milk — I use 2 percent or whole milk, but half and half will also work.
• Sourdough bread — Cut into large pieces. I use homemade sourdough or sandwich bread when I can, but store bought is fine. Just be sure it’s not super fresh, or it won’t absorb the egg mixture and will be soggy.
• Cheese — a mix of cheddar and pepper Jack adds extra flavor. You can use your favorite cheese, though
• Spices — salt, black pepper, Italian seasoning and dried onions
