Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

For the Casserole:

• brioche or French bread, cut into cubes
• large eggs
• whole milk
• heavy cream
• granulated sugar
• brown sugar
• vanilla extract
• ground cinnamon
• salt

For the Topping:

• unsalted butter, melted
• brown sugar
• ground cinnamon
• nutmeg

Directions

1. Prepare the Bread: Lightly grease a 9×13-inch baking dish. Add the cubed bread evenly across the dish.
2. Make the Custard: In a large bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, brown sugar, vanilla extract, ground cinnamon, and salt until well combined.
3. Assemble: Pour the custard mixture evenly over the bread cubes. Press the bread gently to ensure it absorbs the custard. Cover the dish and refrigerate for at least 30 minutes, or overnight for best results.
4. Make the Topping: In a small bowl, stir together the melted butter, brown sugar, ground cinnamon, and nutmeg until well combined. Drizzle this mixture evenly over the soaked bread just before baking.
5. Bake: Preheat your oven to 350°F (175°C). Bake the casserole uncovered for 40–45 minutes, or until golden brown on top and the custard is set.
6. Serve: Let the casserole cool for a few minutes before serving. Top with powdered sugar, maple syrup, or fresh fruit if desired.

FAQs

Can I make French toast casserole ahead of time?

Yes, it’s ideal for preparing the night before. Refrigerate overnight and bake fresh the next morning.

What’s the best bread for this recipe?

Brioche or French bread is preferred for its rich texture and ability to soak up custard without becoming mushy.

Can I use non-dairy milk or cream?

Yes, almond milk, oat milk, or coconut milk can be used along with a dairy-free cream alternative.

Why chill the casserole before baking?

Chilling allows the bread to fully absorb the custard, resulting in a more evenly moist and flavorful bake.

Can I reduce the sugar?

Yes, you can reduce the sugar in both the custard and topping to suit your preference without affecting the structure.

How do I know when it’s fully baked?

The top should be golden brown and the center should feel firm and set when lightly pressed.

Can I freeze this casserole before baking?

Yes, assemble the casserole (without the topping), wrap it tightly, and freeze. Thaw overnight, add topping, and bake as directed.

Is it better served warm or cold?

It’s best served warm, but leftovers can be enjoyed cold or at room temperature.

What can I use instead of nutmeg in the topping?

You can omit it or substitute with ground allspice, cardamom, or additional cinnamon.

Can I use stale bread?

Yes, slightly stale bread works best as it absorbs the custard more efficiently.
