holiday breakfast casserole always sounds so dreamy, right? But let’s be real: waking up at six o’clock to dice, sauté, scramble, and layer everything yourself? Uhh, hard pass—especially on a cozy holiday morning! If you’re the designated breakfast-maker in your house and you’d rather watch the Christmas parade in your PJs, I’m about to flip your life upside down. Let’s talk about the overnight crockpot holiday breakfast casserole that gets things rolling while you snooze. You get all the amazing smells, none of the early-morning guilt.

Why Crockpot Breakfast Casseroles Are a Win

I’ve had my fair share of “oops, forgot to preheat the oven” disasters. Seriously, nothing flips my mood faster than a hungry mob hollering around the kitchen while I’m scrambling eggs by the weak light of the fridge. So, a crockpot breakfast casserole is my favorite secret weapon. Throw it together ahead of time and it cooks away while you sleep.
You can mix up flavors—bacon, sausage, or hey, go all out and toss in some leftover ham. Flexibility is wild, and honestly, that’s what I love about it. Plus, it frees up the oven for fancier holiday things, like cookies (or just keeping plates warm—no judgement).
There’s also something kinda magical about walking into the kitchen and catching that savory, cheesy smell. Makes you feel like you’re in a five-star restaurant but, you know, with way comfier pants.

Ingredients That Work Best

Here’s where I don’t follow strict rules and my grandma’s probably raising her eyebrows somewhere. But hey, I like to keep things simple and tasty. For a solid overnight crockpot holiday breakfast casserole, you want some eggs, shredded potatoes (fresh, frozen, whatever your heart says), and your favorite breakfast meat.
I almost always grab breakfast sausage, but bacon totally works too—heck, mix them if you’re wild. Cheese is also non-negotiable for me, cheddar or pepper jack, sprinkle it on with reckless abandon. Veggies? Spinach, bell peppers, onion, mushrooms, toss in whatever’s hiding in the crisper.
But seriously, don’t overthink it. Even leftover chunks of last night’s chicken work. If you’re a fan of savory breakfast casseroles, take a peek at this carnivore crock pot breakfast casserole for more ideas.

Overnight Cooking Instructions

Alright, so—I’ll admit it, the first time I made this, I slapped it all in the crockpot at midnight because I almost forgot (classic holiday chaos). Didn’t ruin it though! Grease your crockpot (or use one of those life-saving liners). Start with a layer of potatoes, add some meat, cheese, and veggies, and repeat till the ingredients run out.
Whisk up your eggs with some milk (I usually eyeball it, but it’s about a cup for 8 eggs), season with salt and pepper. Pour this over your layers real slow so it soaks in. Set your crockpot on LOW, 7–8 hours. Go to sleep and try not to dream about breakfast—if you can.
If your mornings run late (who am I kidding, yeah, they do), just flip to “keep warm” until everyone tumbles in for food.

Tips for Fluffiness

Okay, confession time: I like my casserole fluffy, not rubbery. Solution? Don’t over-mix the eggs with milk—easy does it. I also try to pat the veggies extra dry, especially if using frozen stuff.
Go easy with too much liquid. If you add extra cheese (can you ever have too much?), maybe sprinkle it on top instead of into the egg mix, gives you that perfect stretchy, golden layer.
Leave the lid on while cooking. I know it’s tempting to sneak a peek, but the steam is what gets you that tender, fluffy bite. Trust me, don’t let curiosity ruin the magic.
Once in a blue moon, someone wants sweet potato in there. If that’s your thing, you’ll love this sweet potato casserole as a side dish, too.

Serving for Holiday Brunch

Here’s my hot take: nobody wants a fancy sit-down on Christmas morning. They want easy and good. So, here’s what I like to do:

Serve straight from the crockpot (who wants more dishes? Not me).
Set out flour tortillas for super lazy breakfast burritos.
Hot sauce, salsa, extra cheese? Put ‘em on the table, let folks go wild.
Pair with coffee or this crock pot gingerbread latte for a little extra holiday hug.

If you somehow end up with leftovers (this barely happens at my place), just reheat them in the microwave. Easy, no fuss. Family brunch sorted, no sweat.

Common Questions

Can I make it without potatoes?
For sure! Swap in bread cubes, leftover rolls, or just load up on veggies. No rules.

Is it OK if my crockpot runs a little hot?
Yeah, just check it an hour before your normal end time, so you don’t end up with an overcooked holiday breakfast casserole.

Can I use non-dairy milk?
Absolutely. Almond, oat, whatever makes you happy. Just don’t skip the cheese unless you’re dairy-free all the way.

How long does it keep?
Two to three days in the fridge, covered up tight. Some people even swear it’s better the second day—leftovers are a holiday miracle.

What size crockpot do I need?
A 6-quart is pretty much gold for big batches. Anything smaller and you might need to cut the recipe down a bit.
