• 2 teaspoons vanilla extract
• 1 teaspoon cinnamon
• Pinch of salt

• ¼ cup cold butter, cubed

• ½ cup powdered sugar
• 1–2 tablespoons milk
• ¼ teaspoon vanilla extract

Instructions to Prepare Blueberry French Toast Casserole

Step 1: Prepare the Baking Dish

Lightly grease a 9×13-inch baking dish with butter or non-stick spray. This prevents sticking and makes serving easier.

Step 2: Arrange the Bread

Cut the bread into roughly 1-inch cubes and spread them evenly in the baking dish. Using slightly stale bread helps it absorb the custard mixture better without getting soggy.

Step 3: Add Blueberries

Sprinkle half of the blueberries evenly over the bread cubes. Reserve the other half for later to top before baking.

Step 4: Make the Custard Mixture

In a large mixing bowl, whisk together eggs, milk, cream, sugar, vanilla, cinnamon, and salt until well combined. The mixture should be smooth and slightly frothy.

Step 5: Combine the Mixture and Bread

Slowly pour the egg mixture over the bread cubes, pressing them down gently so all pieces absorb the liquid. Sprinkle the remaining blueberries on top for extra flavor and color.

Step 6: Prepare the Topping

In a separate bowl, mix flour, brown sugar, and cinnamon. Cut in the cold butter using a fork or pastry cutter until the mixture forms small, crumbly pieces resembling coarse sand.

Step 7: Add the Topping

Sprinkle the crumble mixture evenly over the top of the casserole. This will create a sweet, crisp layer once baked.

Step 8: Rest or Chill

If preparing ahead, cover the dish tightly with plastic wrap and refrigerate overnight. This allows the bread to soak up the custard fully.
If baking immediately, let it rest at room temperature for 15–20 minutes.

Step 9: Bake

Preheat your oven to 350°F (175°C). Remove the cover and bake the casserole for 40–45 minutes, or until the top is golden and the center is set. The edges should be slightly crisp, while the middle remains soft and fluffy.

Step 10: Add Glaze and Serve

Whisk together powdered sugar, milk, and vanilla to make a simple glaze. Drizzle it over the warm casserole before serving. Enjoy with maple syrup, whipped cream, or a sprinkle of fresh blueberries.
