Overnight Brioche French Toast Casserole
This overnight Brioche French Toast Casserole is soaked in a sweet maple syrup custard and topped with a buttery cinnamon streusel. Easy to prep ahead and bake in the morning for a sweet, cozy breakfast. Dairy-free option, too!
Ingredients
French Toast Casserole:
- 1 loaf brioche bread (stale is best_), 14 - 16oz, cut into 1-inch cubes.
- 1 ⅔ cups oat milk or unsweetened almond milk, vanilla or plain
- 6 eggs
- ¼ cup pure maple syrup
- 1 tablespoon vanilla extract
- 1 teaspoon ground cinnamon
Streusel Topping:
- ⅓ cup all-purpose flour, spoon & leveled
- ⅓ cup coconut sugar, or light brown sugar
- ½ teaspoon ground cinnamon
- 5 tablespoon cold unsalted butter, cubed
- Optional Topping: fresh berries, maple syrup and/or powdered sugar for topping
Instructions
Prepare (Night Before):
- Lightly grease a 9x13" baking pan with nonstick spray or butter.
- Add cubed brioche to the greased baking dish.
- In a medium bowl, whisk together almond milk, eggs, maple syrup, vanilla extract, and cinnamon. Pour mixture over bread and use your hands to make sure all pieces of bread are saturated.
- Wrap the baking dish with tin foil and let it sit in the refrigerator for at least 4 hours or overnight, if possible.
Bake (Day Of):
- Once ready, preheat the oven to 350°F.
- Make the streusel topping by adding all the ingredients to a small mixing bowl. Use two knives or your hands to “cut” the cubed butter into the flour. It should be crumbly.
- Once the oven is heated, remove the tin foil, evenly sprinkle the streusel on top of the casserole, and bake for 40 - 50 minutes, until the top is golden brown. If browning too fast, add tin foil back on top during the last 15 minutes. Remove from oven and let cool for 5 minutes.
- Sprinkle with powdered sugar, if desired, and serve with fresh berries. Enjoy!
Notes
MUST soak in the fridge for at least 4 hours. Overnight is best!
Best bread to use: Brioche is the star here—it’s soft, buttery, and soaks up the custard beautifully. Challah or Texas Toast also work well.
Use stale bread if you can: It holds up better and won’t get soggy. If your bread is fresh, slice it up and bake at 250°F for 10 minutes to dry it out before using.
Make it dairy-free: Use almond or oat milk and swap the butter for vegan butter or solid coconut oil.
Customize it: Try mixing in fresh or frozen berries, chocolate chips, or chopped nuts before baking for a fun twist!
