Preparing Blueberry French Toast Casserole
Making a delicious Blueberry French Toast Casserole is a delightful experience! This dish not only tantalizes the taste buds but can also be prepared in advance, making it perfect for brunch gatherings or special occasions. Let's dive into the steps.
Preparing the baking pan
To get started, you’ll want to prepare your baking pan. Grab a trusty 9×13-inch pan and grease it generously with butter or nonstick spray. This step is crucial to prevent sticking, ensuring that you can easily serve those delicious slices later. If you prefer, you can line the pan with parchment paper for extra protection—just remember to leave some overhang for easy removal after baking!
Cubing the bread and layering
Next, it's time to choose your bread. A loaf of French bread, sourdough, or even brioche makes for an ideal base. Slice the bread into one-inch cubes—aim for about twelve cups of bread in total. Spread these lovely cubes evenly in your prepared pan, making sure they’re snug but not squished together. Now, sprinkle a delightful cup of fresh or frozen blueberries over the top. The antioxidants in blueberries, as highlighted by sources like the USDA, not only add flavor but also nutritional value!
Mixing the egg custard
In a large mixing bowl, whisk together eight large eggs, two and a quarter cups of whole milk, half a teaspoon of ground cinnamon, three-quarters of a cup of packed light brown sugar, and a tablespoon of pure vanilla extract. This egg custard is the heart of your casserole. Ensure there are no lumps of brown sugar sticking around; we want a smooth mix that will envelop the bread beautifully.
Refrigerating for optimal flavor
After pouring the egg mixture over the bread and blueberries, cover your pan tightly. This is where the magic happens! Refrigerate it for anywhere between three hours to a full day—overnight is usually best. This resting period allows the bread to absorb the custard, making each bite deeply flavorful and scrumptiously rich.
Making the streusel topping
While your casserole is soaking away, let's not forget about the scrumptious streusel topping! In a medium bowl, mix a third cup of brown sugar, a third cup of all-purpose flour, and half a teaspoon of cinnamon. Cut in six tablespoons of cold, cubed unsalted butter until the mixture resembles crumbly sand. Sprinkle this topping over the bread mixture just before baking—it will create that perfect, crispy layer.
Baking and achieving golden perfection
When you're ready, preheat your oven to 350°F (177°C) and bake your casserole for 45 to 55 minutes. You’ll know it’s done when the top is beautifully golden brown and a toothpick inserted comes out clean. I often check at the 45-minute mark for that soft yet firm consistency. Serve it warm, and don’t forget the optional toppings—extra blueberries or a drizzle of maple syrup can truly enhance this heavenly dish!
By following these straightforward steps, you’ll have a Blueberry French Toast Casserole that’s sure to impress at any gathering. Happy baking!

Variations on Blueberry French Toast Casserole
Berry Medley Variation
For a twist on the classic blueberry French toast casserole, consider a berry medley! Use a mix of fresh or frozen berries like strawberries, raspberries, and blackberries. This not only enhances the flavor but also adds a beautiful pop of color to your dish. The sweet-tart balance from the mix will make every bite a delightful surprise. Enjoy your creation with a drizzle of homemade maple syrup for an extra touch!
Seasonal Fruit Twist
Why not make your casserole sing with the seasons? In the fall, replace blueberries with sliced apples or pears tossed in cinnamon. For winter, add cranberries for a refreshing zing. This seasonal approach keeps your casserole exciting and lets you experiment with flavors throughout the year. You can even try this bread pudding style dish with peaches in the summer for a juicy delight.

Cooking Tips and Notes for Blueberry French Toast Casserole
Best Bread Choices for Texture
For the perfect blueberry French toast casserole, choosing the right bread is essential. Opt for a stale loaf of French bread, brioche, or challah; these varieties soak up the custard beautifully, leading to a delightful texture. Day-old bread works best, but if you’re short on time, simply toast fresh cubes in a 300°F oven for 10 minutes to achieve a slightly stale consistency.
Make-Ahead and Freezing Options
This recipe shines as a make-ahead dish. Prepare the casserole the night before and allow it to soak in the fridge. Want to stash some for later? Assemble the casserole without baking, wrap it tightly, and freeze for up to two months. Thaw in the refrigerator overnight and bake as usual—it's a convenient option for crowded brunches!

Creative Serving Ideas
