Browned sausage, eggs, and cheddar soaked into buttered bread overnight — assemble it tonight, refrigerate eight hours, and bake it while the coffee brews.
Three things that make the overnight version work
This casserole does its real work in the refrigerator, and these are the three places it goes right or wrong.
- Butter side down: The butter sits against the hot dish, so the bottom browns instead of going soggy.
- Drain the sausage well: Grease left in the pan ends up in the eggs.
- Give it the full eight hours: That is when the eggs and milk soak all the way into the bread.
This sausage breakfast casserole is absolutely delicious and so so easy. You’ll love that it’s a make ahead breakfast recipe so you assemble it the night before and allow the flavors to come together overnight and pop it in the oven in the morning.
A hearty breakfast that takes no time in the morning while you enjoy your coffee.
The night before is where all the work happens, and that is the whole trick. In the morning the only job left is turning on the oven, and breakfast bakes itself while the coffee does its thing.
Overnight Breakfast Sausage Casserole with Bread
When I look to make a new breakfast casserole, for some reason I always reach for the sausage. And, I must admit, the carbs, too.
This is a good easy sausage breakfast casserole with bread as the main filler – accompanied by the usual suspects, including eggs, milk and cheese.
Maybe the best part? It’s an overnight casserole with bread where the eggs and milk have a chance to soak into the casserole really well over night.
Delicious!
Can Sausage Breakfast Casserole be Frozen?
This isn’t a great breakfast casserole to freeze (sorry!). But, it’s about as easy as it comes since it can be made the night before.
However, one time saving tip would be to cook and crumble the sausage the night before. Drain and freeze the sausage and put it in a quart size freezer bag and store it in the fridge for up to a couple days before using, or put it in the freezer.
Either will do the trick and will save you about ten minutes.
Is This a Good Breakfast Casserole for the Week?
This is a fabulous breakfast casserole for the week. If you need easy dinner ideas, this is a fabulous casserole to whip up as you’ll be able to let it sit all day, and then pop it in the oven when you get home rom work, serve with fruit and you’ve got a complete meal!
Is this a Breakfast Casserole That Can Be Made the Night Before?
Sure is! In fact, that’s even in the instructions!
You’re going to want to let this casserole sit overnight to let the flavors come together.
Here’s how I whip this easy sausage casserole up.

Why the Overnight Rest Matters
The eight hours in the fridge aren’t optional, and they aren’t just for convenience. That is when the eggs and milk soak all the way into the bread.
Bread that has soaked overnight bakes up soft and custardy instead of dry. That is the difference between a real overnight casserole and eggs sitting on toast.
What I Have Learned Making This
Press the bread in butter side down. The butter ends up against the hot dish, so the bottom browns instead of going soggy.
Drain the sausage well after browning it. Any grease you leave in the pan ends up in the eggs, and nobody wants that.
Bake it uncovered the whole time, forty to forty-five minutes at 350. No foil means the top gets some color while the middle finishes.
This is the breakfast I make when tomorrow morning is already spoken for. A few minutes of putting it together tonight, and in the morning you just look like you have it all together.
