This recipe for Overnight Sausage Breakfast Casserole is a great make-ahead breakfast dish! With basic ingredients like bread, sausage, cheese, and eggs, it's a hearty meal that's perfect for Christmas morning.
This is a post that has needed an update for years.
Way back in 2011 (well before Pinterest was a big thing), I published the original version of this recipe on this blog. That post didn't even have a picture on it! But it continues to be a favorite recipe in our home, even after all these years – so I decided to give it the appropriate blog post today.
I can't take credit for this recipe – as a matter of fact, my father-in-law is famous for this one. I've tried for years to make it as well as he does…and I can't. Nobody can. In our family, we're all convinced he has some kind of voodoo magic over the breakfast casserole recipe that makes it so much better than everyone else's attempt. Or, he's holding back a couple of secret ingredients from the rest of us. 🙂 Nevertheless, I continue to try. I'm able to *almost* make it as well as he does.
This makes for an easy next-day breakfast or even a breakfast for dinner – it's hearty enough to be a full meal on it's own. I usually pair it with some fruit or a light pastry/bagel – it doesn't need a lot of extra bells and whistles at all! And you guys know I'm a sucker for a prep-ahead recipe – this one is easy to whip up the night before and pop in the oven the next morning (hello, Christmas morning).
Overnight Sausage Breakfast Casserole is a go-to for any meal in our family – I hope it becomes one for your family too. Let's take a look at the recipe!
Overnight Sausage Breakfast Casserole
- 16 oz hot sausage
- 10 slices white bread crusts removed
- 2 cups whole milk
- 10 eggs
- 1/2 tbsp salt
- 1/2 tbsp pepper
- 2 tbsp yellow mustard
- 2 cups sharp cheddar cheese shredded
- Cook and crumble the sausage in a large skillet. Drain.
- Remove crusts from white bread and tear into 1" chunks. Layer in the bottom of a greased 9×13" baking dish. Layer cheese over bread; add drained sausage over cheese.
- In a large bowl, whisk together milk, eggs, salt, pepper, and mustard until blended. Pour this mixture over the top of the casserole, ensuring all of the bread is soaked.
- Allow casserole to rest in the fridge for 8-10 hours.
- When ready to serve, bake at 375 degrees for 45-50 minutes, until entire casserole is set and top starts to brown.
