Eggnog French Toast Casserole with Bourbon Glaze: Easy Whole Wheat Eggnog Breakfast Casserole is made with a simple nutmeg custard but finished with an impressive Bourbon Glaze. 

Shut the front! Did I just say eggnog, french toast, and bourbon together?

Did I mention it was perfectly acceptable for breakfast?!

Well, Merry Christmas to you and yours!

I am serious, this French Toast casserole that is infused with festive notes reminiscent of Eggnog, is the perfect way to usher in Christmas morning.

Plus you assemble this the night prior to baking! Which yes, that gets you out of the kitchen and with your family! 

Truthfully, unless we are talking about my Coconut Milk Eggnog, Eggnog has never been my favorite holiday drink. I think that I was ruined by overly sweetened drinks that were a bit too rich for my enjoyment.

However, it is something my husband requests each year at Christmas time.

And when you look at the players for Eggnog–eggs, nutmeg, cream, and sugar, it is simply the starting of a custard.

Custards? I love custards. They are perfect for ice cream, puddings, trifles, and bread puddings or french toast. I just don’t want to drink a thick raw custard.

So if Eggnog is a technically a custard, why wouldn’t it be the perfect base for french toast?

And that is when this little casserole creation popped into my brain.

Overnight Eggnog French Toast Casserole

I flip over french toast. It is one of my hidden love languages I believe and one of many of my favorite breakfast recipes to prepare.

So if I could combine my love of French Toast with my husband’s love of Eggnog AND serve in the morning with ZERO work, what could be better?

And I am so glad that it worked–totally NAILED IT with this one! Not to brag or anything.

How to Make Overnight French Toast Casserole with Bourbon Glaze

In order to make a delicious overnight breakfast casserole, the bread is key. You want a thick sliced bread that is slightly dried out, therefore making it able to absorb the custard of your choice. I chose to use my whole wheat bread recipe that had been diced into 1 inch cubes. To ensure my bread was dried out, I left the cubes of bread sit out, uncovered, several hours.

Next, you just have to whip together a custard. Like I said, a custard base is cream or dairy-free milk of some sort paired with eggs, sugar and flavorings of your choice. Since I am choosing to highlight Eggnog, I went for a combination of milk, half-and half, tons of nutmeg, eggs and sweetened with maple syrup (because maple syrup goes perfectly with french toast.)

Once your French Toast Casserole is assmebled,  you need to let your bread sit in that custard for at least 12 hours to fully absorb the richness of the custard. To me that is part of the beauty of this breakfast casserole, it is made the night before so I can focus on enjoying a quiet cup of coffee or grabbing a shower while breakfast bakes with NO work on my part.

The Bourbon Glaze

Every good french toast needs a good topping.

Maple syrup is an obivious choice, as is fresh fruit and whipped cream.

But to make this casserole Holiday worthy, what about throwing a bit of bourbon into the mix? And since Eggnog has traditionally been served with a shot of bourbon, A bourbon glaze only seemed fitting.

But you can leave the Bourbon out of this glaze for the kiddos or non-drinkers in your family. 

I made a simple cream cheese glaze the night before I served the casserole and in the morning added a bit of Bourbon to the adult’s portions. And WOW! Since I am not a liquor drinker just a whiff of bourbon was all I needed to wake up, no coffee necessary!!

Notes on Overnight Eggnog French Toast

• I like to use whole wheat bread for a dose of whole grains, but any thick bread will work for this casserole. Or make gluten-free eggnog french toast by using gluten-free bread. Another great Gluten-Free option, is this Gluten-Free Chai French Toast from my friend at Flippin Delicious.
• To make this dairy-free eggnog french toast, substiute the milk and half-and-half for coconut milk or almond milk. And grease the casserole dish with coconut oil instead of butter.
• It is crucial to use freshly grated nutmeg (whole nutmeg grated with microplane) instead of dried nutmeg for the best flavor in this Eggnog Breakfast Casserole.
• If you would like to have the flavor of bourbon without the alcohol content, add the tablespoon of bourbon to the egg custard. The alcohol will bake off and just the flavor of bourbon will remain.
• You can also make this in individual 1 cup casserole dishes. Just evenly divide among 12 1-cup ramekins that have been greased and adjust the baking time to 30 minutes.
