Why You’ll Love This Recipe
In creating this recipe, it became clear that the line between “breakfast casserole” and “bread pudding” became completely blurred, and I have zero problem with that.
Here’s a few good reasons to try this delicious breakfast casserole:
- This recipe is best when it can be made the night before to eat the next morning, which is perfect and needed for house guests and gatherings throughout the year.
- An overnight soak in the refrigerator makes the currants plump up, the brioche is hydrated with a vanilla custard, and all is right with the world.
- This recipe is perfect with some scrambled eggs, bacon or sausage and fresh fruit for a hearty breakfast. Perfect for a holiday morning.
- It’s also great for weekend mornings, it’s an easy recipe that uses basic ingredients.
Ingredients You’ll Need
For the full recipe, list of ingredients and instructions, please scroll to the recipe card below.
- Brioche: Buttery brioche bread is usually sold already sliced in a loaf from the grocery store, but you can use a loaf from the local bakery. Slightly stale bread is best.
- Eggs: Large, please.
- Butter: Unsalted butter, softened.
- Milk: Whole milk or almond milk.
- Cream: This isn’t diet food remember.
- Maple Syrup: For it’s incredible flavor.
- Brown Sugar: Same.
- Pecans: The base of the crumble topping.
- Vanilla: A sweet note in the custard.
- Cinnamon and Nutmeg: Must-haves for this delicious recipe.
Step-By Step Instructions
- Start by buttering your baking dish, all over and up the sides of the dish.
- Cut the brioche loaf into 1-2″ inch cubes. Add it to the prepared dish.
3. Whisk together a custard with the eggs, cream, milk, spices and vanilla in a large mixing bowl.
4. Make a quick crumb topping with melted butter, toasted pecans, brown sugar, nutmeg and cinnamon.
5. Sprinkle the currants over the cubed bread. Pour the custard mixture over the top. Toss a little with your fingers, then drop the crumb topping all over and let it sit in the refrigerator for 6-8 hours or overnight.
Bake with aluminum foil for the first 20 minutes, then remove it and continue baking for another 30-35 minutes. Serve with warm maple syrup.

Frequently Asked Questions
Use an airtight container for up to three days in the refrigerator.
Sure can, but I’d suggest using two 9 x 13″ casserole dishes to bake them separately rather than one large dish.
Sure, any dried fruit would work. Try golden raisins, cherries or dried cranberries.
It’s very good on this french toast casserole, but try raspberry jam or date syrup for variation.

Overnight Brioche French Toast Casserole
Ingredients
- 1 loaf Brioche Bread, approx. 1 (one) pound, 4 (four) ounces, cut into cubes
- 2 tablespoons Butter, softened
- ⅓ cup Currants see note
- 6 large Eggs
- 1½ cups Heavy Cream Can be non-dairy cream, see note.
- ½ Cup Milk Can be non-dairy milk, see note.
- 1 teaspoon Kosher Salt
- 1 teaspoon Ground Cinnamon
- ½ teaspoon Ground Nutmeg
- 2 tablespoons Pure Vanilla Extract
- 2 tablespoons Maple Syrup
- Crumble Topping
- ½ cup Whole Pecans, toasted and chopped see note
- ½ teaspoon Kosher Salt
- ¼ cup Brown Sugar
- 2 tablespoons All-Purpose Flour
- 1 teaspoon Ground Cinnamon
- ¼ teaspoon Ground Nutmeg
- 3 tablespoons Melted Butter
- Maple Syrup, for serving
Instructions
- Cut the brioche into 1 ½ – 2 (two) inch cubes. Smear the softened butter inside of the baking dish, all over the bottom and up the sides. Add the cubed brioche to the buttered dish. Sprinkle the currants over the brioche cubes. Make the custard in a large mixing bowl by whisking the eggs with the heavy cream, milk, salt, cinnamon, nutmeg, vanilla and maple syrup. Pour this egg mixture over the brioche, and let it sit while you make the crumble topping.
- To make the crumble topping, measure the whole pecans first, toast them at 350F degrees for 8-10 minutes, then finely chop them. In a medium bowl, add the toasted and chopped pecans, salt, brown sugar, flour, cinnamon, nutmeg and melted butter. Combine it together with your fingers to make pea-sized crumbs.
- Toss the brioche in the baking dish lightly with your fingers to make sure all the cubes are soaked in the custard. Drop the crumble topping in small bits all over the casserole, dotting it here and there in no particular pattern.
- Let the casserole sit in the refrigerator for 6-8 hours or overnight, covered with aluminum foil. To bake, preheat the oven to 350F degrees. Pull the casserole out of the refrigerator and allow it to sit at room temperature for 30 minutes before placing it in the oven, then place on the middle rack with the foil on for 20 minutes. Remove the foil, then continue to bake for another 30-35 minutes, until it is set but slightly jiggly in the middle. Let the casserole rest for a few minutes before slicing and serving with warm maple syrup.
- Alternatively, you can place the covered casserole directly from the refrigerator into your cold oven, and then turn the oven on to heat to 350F degrees. Just add about 5 minutes to your baking time if you cold start the baking like this.
