Preparing Blueberry French Toast Casserole
Creating an unbelievable blueberry French toast casserole is a delightful journey that culminates in a soft, custardy treat bursting with juicy blueberries. The best part? You can prep it the night before, making it perfect for brunch gatherings or cozy family breakfasts. Let’s walk through the steps together!
Gather Your Ingredients
Before you start, make sure you've rounded up all your ingredients. Here’s what you’ll need:
- 1 loaf of French bread, challah, or brioche
- 1 cup of fresh or frozen blueberries
- 8 large eggs
- 2 and ¼ cups of whole milk
- ½ teaspoon of ground cinnamon
- ¾ cup of packed light brown sugar
- 1 tablespoon of pure vanilla extract
For the streusel topping, grab:
- ⅓ cup of packed brown sugar
- ⅓ cup of all-purpose flour
- ½ teaspoon of ground cinnamon
- 6 tablespoons of unsalted butter, cubed
Cube the Bread and Prepare the Baking Dish
Start by greasing a 9x13-inch baking pan with butter or nonstick spray. Next, slice your bread into cubes, aiming for about 1-inch pieces. This helps create that perfect texture when baked. Spread your bread cubes evenly in the prepared pan, and don’t forget to sprinkle the blueberries on top!
Whisk the Custard Mixture
In a large mixing bowl, whisk together the eggs, milk, cinnamon, brown sugar, and vanilla extract. Mix until there are no lumps of brown sugar remaining. This custard mixture is what makes your blueberry French toast casserole rich and delicious!
Combine Bread and Custard, then Refrigerate
Once your custard is ready, pour it evenly over the cubed bread and blueberries. This is where the magic begins! Cover the pan tightly with plastic wrap and pop it in the fridge for at least 3 hours or, better yet, overnight. This soak time allows the bread to absorb all those wonderful flavors.
Make the Streusel Topping
When you're ready to bake, preheat your oven to 350°F (177°C). In a medium bowl, whisk together the brown sugar, flour, and cinnamon for your streusel topping. Cut in the cold, cubed butter using a pastry blender or two forks until the mixture resembles coarse crumbs. This topping will add a delightful crunch.
Bake to Golden Perfection
Sprinkle the streusel topping over your soaked bread mixture. Bake your casserole for 45 to 55 minutes, or until it’s golden brown on top. I prefer mine baked for around 45 minutes for a softer texture. Once done, let it cool slightly before serving warm with optional toppings like maple syrup or a dusting of powdered sugar.
If you plan to impress your friends or family during brunch, this blueberry French toast casserole is a showstopper! Make sure to save this recipe for your next gathering—you won’t regret it.

Cooking tips and notes for Blueberry French Toast Casserole
Best bread types for optimal results
Choosing the right bread is essential for an unbelievable blueberry French toast casserole. Stick with thick, sturdy loaves like French bread, brioche, or challah. These varieties can handle the custard mixture without turning mushy. For the best texture, try using day-old bread, which absorbs the flavors beautifully. If fresh bread is all you have, toast the cubes lightly in a low oven for about 10 minutes to help them absorb more custard.
Techniques for a gooier center
Want that luscious, gooey center in your casserole? Soak the bread for at least 6 hours, or overnight if possible. This allows the egg mixture to fully penetrate the layers. After baking, let the casserole rest for about 10 minutes before slicing—this helps to set those delicious layers. Top with your favorite syrup or a dusting of powdered sugar for added decadence.

Ideal drinks to accompany
Finding the perfect beverage to enjoy with your casserole is a breeze! Freshly squeezed orange juice offers a bright, citrusy contrast, while a creamy cappuccino or a hot cup of herbal tea can enhance the cozy brunch vibe.
