Ingredients
- Texas Toast bread: Choose a thick cut bakery style loaf for the best soak and plush texture
- Eggs: Large eggs create a rich custard that holds the casserole together
- Eggnog: The star of this recipe for festive flavor and creamy sweetness Use a high quality full fat eggnog for best results
- Milk: Balances the richness of the eggnog and lightens the custard
- Rum flavoring: Gives an authentic holiday note without alcohol Pure extracts offer a smooth finish
- Cinnamon: Adds warmth and depth for that classic French toast taste Freshly ground cinnamon releases the most aroma
- Nutmeg: Brings gentle spice that pairs beautifully with eggnog For bold taste grate whole nutmeg
- Unsalted butter: Melting butter gives the topping a lovely crisp finish and rich flavor Look for butter with a sweet creamy aroma
- Light brown sugar: Creates the delicious caramelized crust Choose a soft moist sugar for easy blending
- Pecans (optional): For crunch and toasty nuttiness Toast before chopping to enhance flavor and avoid a bitter bite
Instructions
- Mix the Custard:
- Whisk together eggs eggnog milk and rum flavoring in a large bowl until smooth and well combined This creates a creamy base that soaks into every bread cube
- Build the Casserole:
- Dip each cube of Texas toast into the egg custard mixture so every bite is evenly coated Gently transfer the cubes into a nine inch baking dish and pour any remaining custard over all the bread This ensures no piece is dry
- Season and Rest:
- Sprinkle cinnamon and nutmeg evenly over the top of the soaked bread for fragrant flavor Cover the dish with foil and let it rest in the refrigerator overnight or at least four hours This time allows every piece to fully absorb the custard
- Prepare the Topping:
- Combine melted unsalted butter with light brown sugar in a small bowl Stir until completely blended for a glossy mixture that creates the perfect sweet crust
- Finish and Bake:
- Pour the butter sugar mixture evenly over the casserole then add chopped pecans if using Bake uncovered at three hundred fifty degrees Fahrenheit one hundred seventy five Celsius for about forty minutes The top should be golden and bubbling and the center just set
- Serve warm:
- Scoop generously and savor every bite

My favorite part is always the golden brown edges that crisp up from the butter sugar topping My kids love sneaking into the kitchen before breakfast to beg for the first piece
Storage Tips
Cool leftovers completely before storing Cover the baking dish with plastic wrap or transfer slices to an airtight container Refrigerate for up to three days For longer storage freeze individual portions wrapped tightly in foil and reheat in the oven until warmed through This casserole does not lose flavor or texture when frozen and reheated
Ingredient Substitutions
If you cannot find Texas toast thick cut brioche bread or challah work well Almond milk or oat milk can replace regular milk for a dairy free option If you prefer to avoid eggnog try using a blend of milk and cream with extra vanilla and spice Walnuts or sliced almonds can substitute for pecans for nutty crunch
Serving Suggestions
For brunch serve warm dusted with a little powdered sugar or a drizzle of maple syrup Pair with fresh fruit like orange slices or pomegranate seeds I sometimes place a dollop of whipped cream or Greek yogurt on top for extra indulgence This casserole can also be the centerpiece of a festive breakfast buffet
