Holiday Eggnog French Toast Bake

As an avid host, I cherish brunch gatherings and always gravitate towards dishes that can be prepared entirely in advance. Recipes like my savory bacon and egg casserole or my classic overnight French toast casserole are lifesavers, allowing me to fully enjoy the company of my guests instead of being tied to the stove flipping pancakes or scrambling eggs to order. This delightful **Eggnog French Toast Casserole** has been a beloved tradition in my home for Christmas morning for many years.

Interestingly, I rarely drink eggnog on its own, finding it a bit too rich for my palate. However, I absolutely adore its distinct, festive flavor! This culinary contradiction inspired me to create this very recipe several years ago, as a delicious way to utilize leftover eggnog and infuse that unmistakable holiday taste into a breakfast classic. It instantly became a family favorite, especially with my boys, and I couldn’t be happier, given how incredibly simple it is to prepare.

The magic begins with generous chunks of soft, tender challah bread, which are gently submerged in a meticulously crafted custard mixture. This heavenly blend combines creamy eggnog, fresh milk, aromatic ground cinnamon, and vibrant orange zest with wholesome eggs. The entire assembly process takes a mere 15 minutes, making it incredibly convenient for busy holiday schedules.

Once assembled, the French toast casserole is refrigerated overnight, providing ample time for the challah bread to thoroughly absorb the rich eggnog custard. This overnight soak is crucial, transforming the bread into a custardy dream that bakes up soft and reminiscent of a luxurious bread pudding—but one you get to savor for breakfast! The result is a wonderfully moist interior with a perfectly golden, slightly crisp exterior.

This is truly the quintessential make-ahead breakfast for Christmas, New Year’s Day, or any special holiday gathering. Serve it simply dusted with a delicate layer of powdered sugar, or elevate it further with generous dollops of freshly whipped cream and a drizzle of warm maple syrup. For an extra touch of festive elegance, I highly recommend topping it with my bright and beautiful orange sugared cranberries, which add a lovely tart contrast and a pop of color.

Essential Ingredients for Your Holiday Breakfast

Crafting this irresistible eggnog overnight French toast casserole requires a short and simple list of just six primary ingredients. Given that eggnog is inherently sweet, you’ll find no additional sugar is needed in our custard filling, keeping the flavors perfectly balanced. Below is a detailed look at what you’ll need to create this festive masterpiece:

• Challah Bread: My top choice for any French toast casserole, challah bread offers an exceptionally light, airy, and rich texture. Its slightly sweet, eggy crumb soaks up the custard beautifully without becoming soggy. I recommend cutting it into 1-inch cubes, crust and all, for the best results. If your challah is very fresh, consider toasting the cubes lightly to prevent mushiness and encourage optimal absorption.
• Eggnog: The star of our show! Feel free to use your preferred brand and type of eggnog. For those looking to lighten the recipe, a low-fat eggnog works wonderfully without compromising on flavor. Ensure it’s alcohol-free if serving to children or those who prefer it.
• Milk: Incorporating 1 cup of milk helps to mellow the richness and sweetness of the eggnog, creating a perfectly balanced custard. Any type of milk you have on hand will work, from whole milk for extra creaminess to a non-dairy alternative. For an even more intense eggnog flavor, you can substitute the milk with additional eggnog.
• Eggs: Eight large eggs are crucial for forming the rich, custardy base of our French toast. They bind the ingredients together and create that delightful bread pudding-like texture once baked. For a slightly lighter dish, you can use a combination of whole eggs and egg whites.
• Ground Cinnamon: This classic spice is indispensable, providing a warm, comforting sweetness and an aromatic depth that perfectly complements the eggnog and instantly signals holiday cheer.
• Orange Zest: A subtle yet impactful addition, fresh orange zest brightens the overall flavor profile. Its bright, citrusy notes harmonize beautifully with the warmth of cinnamon and the creamy richness of eggnog, elevating the casserole from good to extraordinary.
• Whipped Cream (Optional, but highly recommended): For the ultimate indulgence, prepare a quick batch of homemade whipped cream while your casserole bakes. Its light, airy texture and delicate sweetness are the perfect counterpoint to the warm, custardy French toast.
• Streusel Topping (Optional): If you crave an added layer of texture and sweetness, a simple streusel topping is a game-changer. The recipe card below includes ingredients for this delightful crunchy addition, which truly takes this French toast casserole over the top.

How to Make Eggnog French Toast Casserole

This overnight French toast recipe is wonderfully straightforward, making your holiday mornings truly stress-free. Prepare it the night before, allow it to soak up all the delicious flavors, and simply bake it in the morning for the perfect make-ahead breakfast!

Pro Tip for Perfect Texture: Stale or day-old bread is actually preferable for French toast casseroles, as it absorbs the custard better without falling apart. If your challah bread is very fresh, a quick toast can improve its texture. Slice it into 1-inch cubes and bake at 350 degrees F (175°C) for 5 to 7 minutes until lightly golden and firm before proceeding with the recipe.

For detailed instructions and tips, refer to the full recipe card below.

1. Prepare the Bread: Begin by cutting your challah bread into uniform 1-inch cubes. Distribute these bread cubes evenly across a greased 13×9 inch baking dish. Greasing the dish ensures easy cleanup and prevents sticking.
2. Whisk the Custard: In a large mixing bowl, combine the eggs, rich eggnog, fresh milk, aromatic orange zest, and warming ground cinnamon. Whisk these ingredients vigorously until they are thoroughly combined and smooth, forming your flavorful custard.
3. Soak Overnight: Carefully pour the prepared eggnog custard mixture evenly over the bread cubes in the baking dish. Gently press the bread down into the liquid with a spatula or your hands, ensuring that every piece is fully submerged and has ample opportunity to soak up the delicious flavors. Cover the dish tightly with plastic wrap and refrigerate it overnight (at least 8 hours, or up to 24 hours). This prolonged soak is key to achieving that wonderfully moist, custardy texture.
4. Bake to Perfection: The next morning, preheat your oven to 350 degrees F (175°C). Remove the casserole from the refrigerator and discard the plastic wrap. If using the optional streusel topping (details in the recipe card), sprinkle it evenly over the top of the casserole now.
5. Baking Time: Bake the casserole in the preheated oven for approximately 50 minutes to 1 hour, or until the top is beautifully golden brown and the center appears puffed and set. If the top begins to brown too quickly, you can loosely cover it with aluminum foil to prevent over-browning while the center finishes cooking.
6. Cool and Serve: Once baked, remove the casserole from the oven and allow it to cool on a wire rack for 10-15 minutes. This resting period helps the casserole set and makes it easier to slice. Cut into individual squares, dust with powdered sugar, and serve warm with whipped cream or maple syrup. Enjoy your festive breakfast!

Most commercially available cartons of eggnog are alcohol-free. However, it’s always a good practice to double-check the ingredients list on your specific eggnog carton to ensure it aligns with your preferences, especially if serving children or those who avoid alcohol.

Absolutely! While challah bread is highly recommended for its texture and richness, you can certainly substitute it with other dense, absorbent breads. Excellent alternatives for this eggnog-infused French toast bake include day-old French bread, brioche, or even Texas toast.

You’ll know your Eggnog French Toast Casserole is perfectly baked and ready to come out of the oven when the top has achieved a beautiful golden-brown color and the center is visibly puffed up and set. A knife inserted into the center should come out mostly clean, indicating the custard has cooked through.
