Step-by-Step Cooking Instructions
- Prepare the baking dish
Lightly grease a 9×13-inch baking dish with butter or non-stick spray. Arrange the cubed brioche evenly in the dish, making sure it fills the space without being tightly packed. - Make the custard mixture
In a large mixing bowl, whisk together eggs, milk, heavy cream, granulated sugar, brown sugar, melted butter, vanilla extract, cinnamon, and salt until fully combined and smooth. - Assemble the casserole
Slowly pour the custard mixture over the brioche cubes. Gently press the bread down so it absorbs the liquid evenly. - Rest the casserole
Cover the dish with foil and refrigerate for at least 2 hours or overnight. This step allows the brioche to soak up the custard for maximum flavor. - Bake to perfection
Preheat the oven to 350°F (175°C). Remove the casserole from the refrigerator and let it sit at room temperature for 15 minutes. Bake uncovered for 40–45 minutes, until the top is golden brown and the center is set. - Cool slightly and serve
Let the casserole rest for 5–10 minutes before serving to allow it to firm up and slice cleanly.

Tips for Customizing the Recipe
- Add fruit: Fresh berries, sliced bananas, or diced apples add natural sweetness and texture.
- Enhance the spice: Nutmeg, cardamom, or pumpkin spice can deepen the flavor profile.
- Make it nutty: Chopped pecans or walnuts sprinkled on top create a delightful crunch.
- Try flavored bread: Cinnamon brioche or chocolate brioche offers a creative twist.
- Dairy alternatives: Almond milk or oat milk can be used for a lighter or dairy-free option.

Notes
- Slightly stale brioche bread produces the best texture, as it absorbs the custard without becoming mushy. If using fresh bread, allow it to air-dry for 20–30 minutes before assembling.
For deeper flavor, prepare the casserole the night before and refrigerate overnight. This resting time enhances the custard absorption and overall richness.
FAQs
1. Can Brioche French Toast Casserole be made ahead of time?
Yes, this casserole is perfect for preparing in advance. Assemble everything the night before, cover tightly, and refrigerate overnight. Baking it in the morning allows the brioche to fully absorb the custard, resulting in a richer texture and flavor.
2. Why is brioche bread ideal for French toast casserole?
Brioche has a high butter and egg content, which creates a soft, tender crumb. It absorbs the custard without becoming soggy and bakes into a creamy center with a lightly crisp top.
3. Can regular bread be used instead of brioche?
Regular bread can be used, but the texture and flavor will be less rich. Challah or Texas toast are excellent alternatives if brioche is unavailable.
4. How do you prevent French toast casserole from becoming soggy?
Using slightly stale brioche helps control moisture. Baking uncovered and allowing the casserole to rest for a few minutes after baking also ensures the custard sets properly.
5. Can this recipe be made dairy-free?
Yes, substitute whole milk and cream with almond milk, oat milk, or coconut milk. Use dairy-free butter for best results.
