It’s really straightforward, and honestly, even if you’re not usually a morning person (I feel you!), you can totally handle this. Just follow along, and you’ll have a stunning dish that smells amazing when it comes out of the oven. You can find more great breakfast ideas to complement it too!
Preparation and Browning
First things’s first, let’s get that oven nice and toasty! Preheat it to 350ยฐF (175ยฐC). While that’s heating up, grab your 9×13 inch baking dish and give it a good greasing. Now, into a big skillet goes your sausage. Cook it all up until it’s nicely browned, then drain off most of that grease โ we don’t want a greasy casserole! Toss in your chopped onion and that green bell pepper, and let them soften up for about five minutes. So easy!

Creating the Egg Mixture
In a separate large bowl, get ready to whisk! You’ll simply combine those four large eggs, the milk, that little bit of Dijon mustard (it adds a subtle zing you’ll love!), the salt, and the pepper. Just whisk it all together until it’s nicely blended. It doesn’t need to be super frothy, just well combined.
Combining All Ingredients
Okay, kitchen wizards, this is where it all comes together! Into that bowl with the egg mixture, we’re adding our cubed stale bread (day-old bread is key here, trust me, it soaks up the liquid better without getting mushy!), the yummy cooked sausage and veggie mixture from the skillet, and both of those wonderful shredded cheeses. Now, gently stir everything until it’s just combined. You don’t want to mash everything up; just coax it all together so the bread and fillings are evenly distributed in that lovely egg mixture. Pour this glorious concoction into your prepared baking dish.

Baking and Resting
Time for the oven! Pop that dish into your preheated oven and let it bake for about 45 to 50 minutes. You’re looking for it to be set in the middle and have a beautiful golden-brown color on top. If you wiggle the dish gently, the center shouldn’t jiggle too much โ that means it’s done! The absolute hardest part? Letting it rest for about 5 to 10 minutes before slicing and serving. It needs just a little bit of time to firm up, but then dig in!
Tips for the Perfect Best Breakfast Casserole (Holiday Menu)
Alright, let’s talk about making this Best Breakfast Casserole (Holiday Menu) absolutely perfect every single time. Itโs honestly pretty forgiving, which I love, but there are a couple of little tricks Iโve picked up that really elevate it. For more quick breakfast inspiration, you know where to find me!
First off, about that bread: Day-old bread is your best friend here. Itโs drier and soaks up that dreamy egg mixture like a sponge without turning into complete mush. Fresh bread? It tends to get a bit tooโฆ well, *wet*. So, if your bread is still fresh out of the bag, I just leave it out on the counter for a few hours, cubed up, before I start.
And cheese! While Iโve listed cheddar and Monterey Jack, feel to get creative. A sharp cheddar gives a nice bite, and Monterey Jack melts like a dream. You could even throw in some Gruyรจre for a fancier flavor, or a little mozzarella for extra stretch. Just make sure you’re shredding it yourself from a blockโpre-shredded cheese often has anti-caking agents that can make your casserole a little less creamy and smooth.
Lastly, if you worry about it being too watery, one little trick I learned is to make sure you really drain off all that grease from the sausage and veggies. A well-drained pan makes a big difference in the final texture!

Ingredient Substitutions and Variations
One of the things I adore about this Best Breakfast Casserole (Holiday Menu) is how darn adaptable it is! Life happens, pantries aren’t always perfectly stocked, and taste buds vary, right? So, don’t stress if you need to switch things up. For a different twist, you can totally swap out the breakfast sausage for crumbled bacon, diced ham, or even chorizo for a spicy kick. If you’re looking to sneak in more veggies, chopped mushrooms, spinach, or even some diced sweet potato would be delicious in there. And cheese? Oh, go wild! A sharp white cheddar, smoky gouda, or even a sprinkle of pepper jack would be amazing. It’s all about making it your own!
Serving Suggestions for Your Holiday Breakfast
Now that you’ve got the most amazing Best Breakfast Casserole (Holiday Menu) ready to go, let’s talk about rounding out that holiday spread! This casserole is fantastic on its own, but pairing it with a few other goodies just makes the whole breakfast experience feel even more special. I love serving it with some fresh fruit salad โ the sweetness cuts through all the savory goodness beautifully. A pitcher of freshly squeezed orange juice or some bubbly mimosas are always a hit, too! And for more breakfast ideas, you know I’ve got you covered!
