Ingredients You’ll Need (AKA Your Shopping List)
You won’t need a shopping cart full of weird ingredients for this. Trust me.
- 1 loaf of day-old bread (a brioche or challah loaf works best)
- 8 large eggs
- 2 cups milk
- 1/2 cup heavy cream
- 1/2 cup granulated sugar
- 1 teaspoon vanilla extract
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- For the Topping:
- 1/2 cup brown sugar, packed
- 1/2 cup all-purpose flour
- 1/2 teaspoon ground cinnamon
- 1/4 cup cold unsalted butter, cubed
- Optional: Maple syrup and powdered sugar for serving
Substitutions, IMO: No brioche? A French loaf or even Texas toast works just fine. You can also use a different type of sugar, like coconut sugar or maple sugar.
Tools & Kitchen Gadgets to Get the Job Done
Here’s the gear you’ll need. Nothing complicated, I promise.
- 9×13 inch baking dish
- Large mixing bowl
- Whisk
- Small bowl (for the topping)
- Pastry cutter or a fork
- Measuring cups and spoons
The Super-Simple, Step-by-Step Instructions
Ready? Let’s do this. You’re just a few steps away from a house that smells like Christmas.
- Prep Your Pan. First things first, grease your 9×13 inch baking dish. Cut your day-old bread into 1-inch cubes and arrange them evenly in the dish.
- Make the Custard. In a large mixing bowl, whisk together the eggs, milk, heavy cream, granulated sugar, vanilla extract, cinnamon, and nutmeg until everything is well combined.
- Pour and Chill. Pour the custard mixture evenly over the bread cubes, making sure to get every piece. Cover the dish with plastic wrap and pop it in the fridge for at least 4 hours, or even overnight. This is crucial for a soggy-free casserole.
- Make the Topping. In a small bowl, combine the brown sugar, flour, and cinnamon. Use a pastry cutter or a fork to cut in the cold, cubed butter until the mixture resembles coarse crumbs. Store it in an airtight container in the fridge overnight.
- Bake It Off. In the morning, take the casserole out of the fridge and preheat your oven to 350°F (175°C). Sprinkle the topping evenly over the casserole.
- Cook and Serve. Pop the dish in the oven and bake for 40-45 minutes, or until the top is golden brown and the center is set. Serve it warm with a drizzle of maple syrup and a dusting of powdered sugar.
Calories & Nutritional Info (The Reality Check)
I’m not a nutritionist, so these are just estimates, but IMO it’s totally worth it.
- Estimated Calories per serving: ~400-500 kcal (depending on the size of your slice, let’s be real)
- Key nutrients:
- Carbs: Mostly from sugar, bread, and flour. It’s a breakfast dessert, what did you expect?
- Fats: From the butter, heavy cream, and eggs. These are the good fats that make it so rich.
- Protein: From the eggs and milk. So, it’s basically a health food, right? 😉
Common Mistakes to Avoid (So You Don’t Mess It Up)
Listen up, buttercup. These are the top reasons your casserole might go wrong.
- Using Fresh Bread: If you use fresh bread, it will get too soggy and mushy. Day-old or stale bread is key!
- Not Chilling Long Enough: This is the number one reason for a soggy casserole. The bread needs time to soak up all the custard. Be patient!
- Overbaking: You want a casserole that’s set in the middle, not a dry, hard brick. Stick to the suggested time and check the center before you pull it out.
- Skipping the Topping: The crunchy topping is what makes this casserole so good. Don’t skip it!
Variations & Customizations (Time to Get Creative)
You’ve mastered the classic, now let’s mix it up.
- The Berry Blast: Add a cup of fresh or frozen cranberries, raspberries, or blueberries to the casserole before you pour the custard. The berries add a delicious tartness that cuts through the richness.
- The Spiced-Up Version: For an extra layer of festive flavor, add 1/2 teaspoon of ground ginger and a pinch of ground cloves to the custard mixture. It will smell and taste like Christmas morning.
- The Savory Twist: Ditch the sugar and spices. Use cheddar cheese, bacon, and chives for a delicious, savory casserole. It’s a great alternative for a crowd that might prefer a more savory breakfast.
FAQ Section (Because You Have Questions, I Have Answers)
- Can I make this in a smaller pan? Yes! You can halve the recipe and use an 8×8 inch pan. Just be sure to adjust the baking time accordingly.

- How do I know when it’s done? The top will be golden brown, and the center will be set. You can stick a knife in the center—if it comes out clean, it’s done.
- Can I use a frozen bread loaf? Yes! Just be sure to thaw it and let it get a little bit stale before you cut it up.
- What’s the best way to reheat it? The best way to reheat it is in the oven at 350°F (175°C) for about 10-15 minutes, or until it’s warmed through.
