As the holiday season approaches, my mind drifts to cherished family traditions, and among them, one stands out: preparing my Make-Ahead Sausage, Egg, and Cheese Breakfast Casserole.

Picture this: It’s Christmas Eve, the house is quiet, and the only sound is the gentle rustle of wrapping paper as I tackle the last of the gift wrapping. While everyone else is nestled snug in their beds, visions of sugarplums dancing in their heads, I’m the lone sentinel in the kitchen, pondering the age-old question: How do I feed the masses and still have time to enjoy the magic of Christmas morning?

The Joy of This Make-Ahead Breakfast Casserole Recipe

This hearty country dish isn’t just a meal; it’s a symbol of togetherness, eagerly anticipated by all. And while it’s a staple in our home for Christmas morning, its versatility makes it perfect for any occasion, including weekend brunches throughout the year. This dish can turn even the most chaotic morning into a cozy, comforting affair—just what you need when the in-laws unexpectedly drop by for brunch or the kids have friends over for a sleepover gone wild.

What You’ll Need

Breakfast sausage

If breakfast sausage isn’t in your pantry, you can easily create your own seasoned version with a blend of sage, thyme, crushed fennel seeds, red pepper flakes, a dash of nutmeg, salt, and black pepper.

Eggs

You will need 9 large eggs. For those seeking a lighter option, two egg whites can substitute for one whole egg.

Whole milk

Opt for whole milk for its creamy texture, or indulge even further with half and half. For those with dietary preferences, almond milk or another mild dairy-free alternative can be easily substituted.

Seasonings

Dry mustard and salt are the key players here. If you find yourself without dry mustard, dijon mustard makes for an excellent substitute, offering a similar flavor profile. Simply use one tablespoon of Dijon mustard for each teaspoon of ground mustard.

Bread

Four slices of classic white bread, torn into pieces to soak up the delectable custard.

Grated cheese

Half a cup of your preferred variety. Whether it’s sharp Cheddar for a robust flavor, Monterey Jack for a milder taste, or Pepper Jack to add a kick, the choice is yours.

How to Assemble the Make Ahead Breakfast Casserole

Alrighty, so let’s get this breakfast casserole started! First, grab your 9″x13″ baking dish and give it a good grease with some butter or vegetable oil. Don’t be shy with the grease—it’s what makes the magic happen!

Next, it’s time to tackle that sausage. Get your skillet sizzling over medium heat and break up that sausage. Once it’s browned to perfection, drain it thoroughly.

Now, onto the main event: the egg mixture. In a large bowl, crack the eggs and give them a good whisking. Then, toss in the milk, mustard, and salt, and mix it all up until it’s as smooth.

Once that’s done, it’s time to throw in the rest of the gang: the bread pieces, cheese, and that glorious sausage you’ve been browning. Mix it all together.

Now, pour the mixture into your pre-greased baking dish, cover it up with some plastic wrap, and pop it in the fridge overnight. Yep, you heard me right—we’re letting those flavors mingle and marinate while we catch some Z’s.

The next morning, when you’re bright-eyed and bushy-tailed (or at least caffeinated), pull the baking dish out of the fridge and let it come to room temperature while you preheat the oven to 350°F.

Then, slide the casserole into the oven for about 50 minutes. You’ll know it’s ready when it’s firm throughout and lightly browned on top.

What to Serve with the Casserole

What’s a hearty brunch without a touch of sweetness? That’s where the infamous 3-ingredient cinnamon rolls come into play. Gone are the days of pre-dawn dough wrestling; now, with a simple food hack, I can whip up decadent cinnamon rolls in a mere 40 minutes. It’s a secret I’m thrilled to share, promising you heavenly treats that rival even the most labor-intensive homemade versions. So, serve them up alongside the breakfast casserole, and you’ve got yourself the makings of a perfect family brunch.
