Ingredients
- 1 loaf brioche bread, cut into cubes: Choose a high-quality brioche; it’s worth it! Brands like La Boulangerie or Trader Joe’s have excellent options.
- 6 large eggs: Farm-fresh eggs provide vibrant color and rich flavor.
- 2 cups milk: Whole milk gives a creamier texture, but 2% works too.
- 1/2 cup heavy cream: For that luxurious mouthfeel!
- 3/4 cup granulated sugar: You can substitute with brown sugar for a warmer flavor.
- 1 tablespoon vanilla extract: Go for pure vanilla for a more intense flavor.
- 1 teaspoon ground cinnamon: Cinnamon adds warmth and spice, but feel free to experiment with nutmeg or cardamom!
- 1/4 teaspoon salt: This enhances all the flavors.
- Butter for greasing the baking dish: Use unsalted butter for best results.
- Maple syrup and powdered sugar for serving (optional): A sprinkle of powdered sugar makes a gorgeous presentation!

Prep Notes: Ensure your eggs and milk are at room temperature for optimal mixing and texture!
Step-by-Step Instructions
Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish generously with butter. This helps prevent sticking and adds flavor!
Place the brioche bread cubes evenly in the greased baking dish. Aim for an even layer for consistent soaking.
In a large bowl, whisk together the eggs, milk, cream, sugar, vanilla extract, cinnamon, and salt until well combined. Take your time—this custard is where the magic happens!
Pour the egg mixture over the bread cubes, ensuring that all pieces are soaked. Give it a gentle toss to make sure each cube gets some of that delectable custard.
Cover the dish with plastic wrap and refrigerate for at least 2 hours, or overnight if possible. This allows the bread to absorb the custard fully and develop those dreamy flavors.
When ready to bake, remove the plastic wrap and slip it into your preheated oven. Bake for 45-50 minutes, or until the top is golden brown and the custard is set. Check for doneness by inserting a knife in the center—if it comes out clean, you’re good!
Serve warm with maple syrup and a light dusting of powdered sugar if desired. This step is perfect for adding a sweet touch!
Chef’s Tips: For a crunchier top, you can add a sprinkle of granola or chopped nuts before baking. Just keep an eye on it to prevent burning!
Expert Tips & Tricks
Storage Recommendations: If you have leftovers (which is rare!), cover and store in the fridge for up to 3 days. Reheat in the oven at 350°F until warmed through.
Make-Ahead Instructions: As mentioned, you can prepare this dish the night before. Just follow the steps, then refrigerate overnight. It saves time and elevates its flavor!
Troubleshooting Common Problems: If your casserole comes out soggy, it may mean it was over-soaked or not baked long enough. Adjust your timing next time and check the custard’s firmness.
For Best Results: Use room-temperature ingredients for a smoother mixture and more consistent baking.
