Blueberry Breakfast Casserole Ingredients
For the Casserole

• Vanilla extract – Opt for pure vanilla for the most authentic flavor.
• Ground cinnamon – Infuses warmth and depth into your casserole.
• Salt – Enhances all flavors; kosher salt gives you better baking control.
For the Streusel Topping
• All-purpose flour – Combines with sugar for the streusel’s crunch; use a gluten-free blend if needed.
• Light brown sugar – Adds moisture and sweetness to the topping.
• Sliced almonds – Provides a delightful nutty crunch; substitute with walnuts if desired.

Step‑by‑Step Instructions for Blueberry Breakfast Casserole with Almond Streusel
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven is heating, generously grease a 9×13-inch baking dish with butter or cooking spray to ensure easy removal later. This Blueberry Breakfast Casserole with Almond Streusel needs a solid base to bake evenly, so make sure to cover all corners!
Step 2: Layer the Bread and Blueberries
Cut the stale French bread into cubes and evenly scatter them in the prepared baking dish, creating a generous layer. Gently sprinkle half of the fresh blueberries over the bread, distributing them for even flavor. This initial layer of French bread makes a delightful foundation for your casserole, so take your time to arrange it nicely.
Step 3: Whisk the Custard Mixture
In a large mixing bowl, whisk together the eggs, whole milk, granulated sugar, vanilla extract, ground cinnamon, and salt until thoroughly combined and smooth. This mixture will create a rich custard that bathes the bread and blueberries. Pour it evenly over the layered bread and blueberries, making sure every piece has a chance to soak up the deliciousness.
Step 4: Soak and Add Remaining Blueberries
Gently press the bread cubes down into the custard with your fingers, ensuring they’re soaking well. Top with the remaining fresh blueberries, which will burst with flavor during baking. This Blueberry Breakfast Casserole with Almond Streusel is starting to come together—your kitchen should smell delightfully sweet!
Step 5: Make the Streusel Topping
In a separate bowl, combine the all-purpose flour, light brown sugar, and sliced almonds. Cut in the cold unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. This streusel topping adds that perfect crunch to your casserole, elevating its overall texture and flavor wonderfully.
Step 6: Add the Streusel and Bake
Evenly sprinkle the almond streusel mixture over the soaked bread and blueberry layers, ensuring complete coverage. Place the baking dish in the preheated oven and bake for 45–50 minutes or until the top is golden brown and bubbly. You’ll know it’s done when a toothpick inserted in the center comes out clean—the excitement is building for this Blueberry Breakfast Casserole!
Step 7: Cool and Serve
Once baked, remove the casserole from the oven and allow it to cool for about 10 minutes before slicing and serving. This brief cooling period lets the layers set while keeping the casserole perfectly soft. Serve warm, perhaps with a scoop of Greek yogurt or a drizzle of maple syrup to enhance the experience. Enjoy every delicious bite!
