What is Brioche French Toast Casserole?

Brioche French toast casserole is a baked version of traditional French toast made using brioche bread cubes soaked in a rich custard mixture. Unlike standard French toast, which is made slice by slice, this dish is baked in a large casserole dish, making it ideal for serving multiple people. The casserole is topped with a buttery streusel for added texture and finished with luscious maple butter for that extra layer of decadence.


Ingredients You’ll Need

Below are the ingredients, broken down by category, along with their U.S. measurements:

For the Casserole Base:

  • 1 lb brioche bread, cut into 1-inch cubes (roughly 10 cups)

  • 5 large eggs

  • 2½ cups whole milk

  • 2 tbsp pure maple syrup

  • 1 tbsp vanilla extract

  • ¼ tsp ground nutmeg

  • ¼ tsp kosher salt

For the Streusel Topping:

  • 6 tbsp all-purpose flour

  • 3 tbsp brown sugar (light or dark, depending on your taste)

  • ½ tsp ground cinnamon

  • 3 tbsp melted unsalted butter

For the Maple Butter:

  • ½ cup unsalted butter, softened to room temperature

  • 2 tbsp pure maple syrup


Step-by-Step Instructions

1. Prepare Your Baking Dish

Start by greasing a 3-quart (or a 9×13 inch) baking dish with butter or non-stick spray. This ensures easy removal and keeps the casserole from sticking.

2. Cube the Brioche Bread

Cut your brioche into 1-inch cubes. If your bread is fresh, you can toast it in the oven at 200°F for 20–30 minutes to dry it out. This helps it better absorb the custard.

3. Make the Custard

In a large mixing bowl, whisk together the eggs, milk, maple syrup, vanilla, nutmeg, and salt. Ensure everything is well combined for a smooth custard.

4. Soak the Bread

Place the brioche cubes evenly in your prepared baking dish. Pour the custard mixture over the top, pressing gently so the bread absorbs the liquid. Let sit for at least 20–30 minutes, or cover and refrigerate overnight.

5. Prepare the Streusel Topping

In a medium bowl, mix the flour, brown sugar, and cinnamon. Stir in the melted butter until the mixture resembles coarse crumbs. Store in the fridge if making ahead.

6. Top and Bake

When ready to bake, preheat the oven to 350°F. Sprinkle the streusel topping evenly over the soaked brioche. Bake uncovered for 45–50 minutes, or until golden brown and the center is set.

7. Make the Maple Butter

While the casserole bakes, use a hand mixer to beat the softened butter with maple syrup until smooth and fluffy. Chill until ready to serve.

8. Serve

Let the casserole cool for 5–10 minutes after baking. Serve warm with a dollop of maple butter on each slice. Optional: drizzle with additional maple syrup or a dusting of powdered sugar.

Tips for Success

  1. Use day-old bread: Drier brioche will absorb more custard without turning soggy.

  2. Let it rest: Overnight soaking ensures every bread cube is flavorful and soft.

  3. Keep an eye on baking: If the top is browning too quickly, cover loosely with foil halfway through.

  4. Maple butter magic: For extra flair, add a pinch of sea salt to your maple butter for a sweet-salty contrast.

  5. Reheat gently: Warm individual portions in the microwave or oven to revive the softness without drying it out.


Optional Add-Ins and Variations

Want to switch things up? Here are some creative ways to make the casserole your own:

  • Add fresh or frozen fruit: Blueberries, raspberries, or thinly sliced apples work beautifully.

  • Chocolate chips: Sprinkle mini chips between layers of bread for a dessert twist.

  • Savory version: Omit the sugar and syrup, and instead add cooked bacon or sausage and shredded cheddar.

  • Nutty crunch: Add chopped pecans or walnuts to the streusel topping.


Make-Ahead and Storage

Make-Ahead:
Assemble the casserole and soak overnight in the fridge. Add the streusel topping right before baking.

Storage:
Cool completely, then cover and refrigerate for up to 4 days.

Freezing:
Wrap tightly in plastic wrap and foil. Freeze for up to 2 months. Thaw overnight and bake until heated through.


FAQs

Q: Can I use another type of bread?

A: Yes! Challah, croissants, or even Texas toast make good alternatives. Brioche is preferred for its richness, but feel free to experiment.

Q: Can I reduce the sugar?

A: Yes. You can reduce the sugar in the custard and streusel without significantly changing the recipe’s integrity.

Q: Can I make it dairy-free?

A: Absolutely. Use non-dairy milk like almond or oat and a plant-based butter substitute.

Q: What’s the best way to reheat leftovers?

A: Microwave individual portions for 30–45 seconds or reheat the entire dish in the oven at 300°F for 10–15 minutes.
