Make-Ahead Breakfast Casserole is loaded with sausage, cheese and eggs. Assemble it the night before for a simple, delicious breakfast in no time!

Everyone should have those go-recipes in their recipe box that are tried and true and can be depended on time and time again.
This Make-Ahead Breakfast Casserole is just that.
It’s perfect for Christmas morning, Sunday brunch, or a pot-luck.

THE BEST MAKE-AHEAD BREAKFAST CASSEROLE FOR A CROWD
I first stumbled upon this recipe from Jimmy Dean years ago and clipped it from a magazine for my recipe binder. (That sentence makes me feel old.)
10-plus years later, it’s still one of my favorite breakfasts to share with a crowd.
When I was teaching, we often had early morning, potluck-style breakfast meetings on teacher work days.

We’d all bring a dish to share and this casserole was my go-to because it’s so easy, but it was always one of the first things to disappear.
Okay, the bacon was always the first thing to disappear, but this casserole was a close second.
Even though there are a number of potato breakfast casserole recipes out there, my Make-Ahead Breakfast Casserole is made with bread as the base along with the eggs.
The bread soaks up the eggs overnight and it almost ends up like a savory French toast casserole.

HOW TO MAKE THIS BREAKFAST CASSEROLE
Making this Make-Ahead Breakfast Casserole is so easy, you can practically do it in your sleep.
All you need to do is cook the sausage, and then layer it into a baking dish with the cubed bread, cheese and veggies. I like to toast my bread while the sausage is cooking, but that’s completely optional.

From there, just whisk together eggs with some milk and seasoning, and pour them over the rest of the casserole. After a rest in the fridge, it’s ready to bake.
When I was taking this to work, I would prep everything the night before, refrigerate it overnight and then pop it into the oven while I got ready for work.
I’d cover it with foil and it would still be piping hot by the time our meeting started.

HOW TO CUSTOMIZE THIS RECIPE
In addition to the bread and eggs, I like to load up this breakfast casserole with sausage, cheese, and red bell peppers.
But you can totally customize it by adding in all sorts of vegetables like mushrooms, onions, jalapeno peppers, or tomatoes to make it even more flavorful.
Don’t like sausage? No problem! Try frying up a pound of bacon and crumbling it into the casserole instead.

We're planning a road trip with friends next month and I've been looking for a make-ahead recipe for breakfast for 4. I need something I can prep the day before and pop into the oven while we get dressed and ready to go. This looks like just the thing! I'm going to halve the recipe since there are only 4 of us and I don't want leftovers. I'll serve it with some fruit on the side. Hope this turns out well, because it really sounds delicious!

Hi Julie – Yes, as noted in the recipe card, you can bake it immediately in lieu of refrigerating it overnight. Happy baking! Jamie

My grandma always made this when I was little. It always has been one of my favorite recipes. Thank you so much for sharing! Also, I make it with keto bread— toasted, and fairlife milk. It is equally as good if you are looking for a lower carb option.
