Eggnog Breakfast Casserole is the perfect stress-free Christmas breakfast for your family. It’s a rich and creamy eggnog casserole made with croissants.

We’re breaking out the eggnog! No other drink reminds me of the holidays quite like eggnog. I have to actively remind myself not to drink the whole carton. My kids aren’t, though. They used to call it “yellow milk”. Maybe eggnog is an acquired taste? Anyways, I think it tastes delicious!

Make sure to try my Homemade Eggnog.

This year, I made it my mission to do more than just drink our eggnog. I wanted to use it in some recipes and share them with you. Since I’m the queen of breakfast casseroles these past few months, I figured I’d whip up an Eggnog Breakfast Casserole. I used eggnog in place of the milk/cream. Boy, am I glad I did. This may very well be the best breakfast casserole EVER.

What Type of Bread to Use

For the bread layer, I used croissants. I love the buttery flavor they add to a breakfast casserole, and they bake up really nicely in the oven. If you didn’t want to use croissants, you could easily swap for diced French bread or thick Texas-style toast.

We always sprinkle nutmeg on top of our eggnog, so I had to make sure it was included. It’s mixed in with the eggs and eggnog.

Toppings

Fresh fruit
Chopped nuts
Whipped Cream
A drizzle of maple syrup or honey

For the topping, I sprinkled brown sugar and cinnamon. It bakes into a sweet, crispy crust. Beneath that is the creamy eggnog custard and croissants. You can add maple syrup. Fresh berries also work. I thought it tasted fine on its own, and it didn’t need any extras.

Consider this recipe for Christmas morning! My kids are not fans, but I sure enjoy it. Maybe they’ll like eggnog when they are older? You never know. I was a veggie hater until my early 20s.

You can honestly top your casserole once it is cooked with almost anything. We tend to eat it with fruit on top or even a sprinkle of nuts for a crunchy texture.

Can I Double this Recipe?

Of course, feel free to make as much of this as you like. Doubling the recipe may increase the cooking time, so keep an eye on it when it’s in the oven.

What Type of Croissants to Use

You want to buy the pre-made deli-style croissants for this recipe, not the Pillsbury dough-style croissants. The pre-cooked bakery-style croissants are airy and light and soak up all the custard mixture perfectly, making this one incredible dish to serve.

What to Serve With It

Side of bacon, ham, or sausage
Fresh fruit salad
Scrambled eggs

There is no wrong side to pair next to your bake. Or eat it alone if you don’t want to pair it with anything else. I love serving it next to some meat. It helps to counteract the sweetness of the casserole.

Storage Instructions

If you have leftovers, toss them in the fridge and ensure they are covered. Then you can store this casserole in the refrigerator for 3-5 days. Warm it up in the microwave for a quick reheat, or cover it with aluminum foil and heat it in the oven. This is even great cold if you don’t want to warm it up.

Like any casserole, this tends to offer the best texture fresh and warm, but it still tastes pretty fantastic reheated.
