Step-by-step Preparation of Blueberry French Toast Casserole
Creating a delicious blueberry French toast casserole can transform your breakfast or brunch into a memorable occasion. Follow this step-by-step guide to ensure your casserole turns out perfectly.
Prepare Your Baking Pan
Start by greasing a 9×13-inch baking pan with butter or nonstick spray. This ensures that your casserole doesn't stick and makes for easier serving later on. If you want to take it up a notch, consider lining the bottom with parchment paper for even more convenience. A well-prepped pan is crucial for a hassle-free experience, especially when you're hosting friends or family.
Cube the Bread and Add Blueberries
Next, take your chosen loaf of bread—whether it's French, sourdough, brioche, or challah—and slice it into cubes about 1 inch in size. Spread these fluffy cubes evenly across the bottom of your prepared baking pan. Then, sprinkle 1 cup of blueberries all over the bread. Yes, you can use fresh or frozen blueberries based on your preference or availability. Make sure to distribute the blueberries evenly so every bite bursts with flavor.
Mix the Custard
In a mixing bowl, whisk together 8 large eggs, 2 and ¼ cups of whole milk, ½ teaspoon of ground cinnamon, ¾ cup of packed light brown sugar, and 1 tablespoon of pure vanilla extract. Ensure there are no lumps of brown sugar remaining in the mixture; this is your custard base that will soak into the bread. Pour this luscious mixture evenly over the bread and blueberries. The custard helps bind all the flavors together while soaking into the bread, making each bite a delightful explosion of taste.
Cover and Refrigerate
Once everything is in the pan, cover it tightly with plastic wrap or aluminum foil and pop it into the refrigerator. A soaking time of 3 to 24 hours is ideal—overnight is the best choice if you can manage it. This step is critical because it allows the bread to absorb all the delicious custard, making the casserole rich and flavorful.
Make the Streusel Topping
When you're ready to bake, preheat your oven to 350°F (177°C). In a separate bowl, prepare the streusel topping by mixing together ⅓ cup of brown sugar, ⅓ cup of all-purpose flour, and ½ teaspoon of ground cinnamon. Cut in 6 tablespoons of cold, cubed unsalted butter using a pastry blender or two forks until the mixture resembles coarse crumbs. This buttery topping will give your casserole that perfect crunch when baked.
Bake to Perfection
Sprinkle the streusel mixture generously over the soaked bread and blueberries. Then, slide the pan into your preheated oven and bake for 45 to 55 minutes. The casserole should emerge golden-brown on top, and you can choose to bake it a little less if you prefer a softer texture. The aroma wafting through your kitchen will undoubtedly have everyone gathering around in anticipation!
This guided approach not only makes the process feel approachable but guarantees a delicious blueberry French toast casserole that will impress even the pickiest of eaters. Enjoy!

Variations on Blueberry French Toast Casserole
Substitute Berries for Seasonal Fruits
While blueberries are a delicious choice in your Blueberry French Toast Casserole, feel free to mix things up! For spring or summer, consider using strawberries, blackberries, or peaches. As the weather cools, try sliced apples or spiced pears for a cozy fall vibe. Even cranberries can add a delightful tartness! The versatility of fruits means you can effortlessly adapt this dish to reflect the season.
Explore Different Types of Bread
The choice of bread can elevate your French toast casserole. Instead of the usual French or brioche bread, why not opt for challah for its rich flavor or even sourdough for a tangy twist? You can also experiment with whole grain or gluten-free varieties if you’re feeling creative. Each bread type will lend a unique texture and taste to the casserole, making it your own signature dish.
