Step-by-Step Instructions for Blueberry French Toast Casserole

Step 1
Begin by prepping the bread for your Blueberry French Toast Casserole. Take your thick bread—whether challah, sourdough, or French—and cut it into evenly sized cubes, about 1-inch in diameter. If your bread isn’t slightly stale, you can toast it in a 300°F oven for about 10 minutes to dry it out slightly. This helps the bread absorb the custard without becoming soggy.

Step 2
In a large mixing bowl, create the rich egg custard that will elevate your casserole. Whisk together the eggs, whole milk, cinnamon, and vanilla extract until the mixture is smooth and well combined. You want it to be airy and fluffy, which should take about 2-3 minutes. This step is essential for binding the casserole together, ensuring a delightful, creamy texture after baking.

Step 3
To assemble the Blueberry French Toast Casserole, start by layering half of the bread cubes in a greased 9x13-inch casserole dish. Sprinkle a generous amount of fresh blueberries over the bread, then add the remaining bread cubes on top. Pour the prepared egg custard evenly over the entire dish, ensuring every piece of bread is soaked in the savory custard. Let it sit for a moment to absorb the flavors.

Step 4
(Optional) Prepare the delicious streusel topping by mixing together the brown sugar, flour, and cinnamon in a medium bowl. Use very cold butter and a pastry blender or two forks to cut the butter into the flour mixture until it resembles coarse crumbs. This step adds a sweet, crunchy texture that contrasts beautifully with the custard-soaked bread.

Step 5
Cover the casserole dish tightly with plastic wrap and refrigerate it overnight, or for at least 3 hours. This resting time allows the bread to absorb the custard fully, resulting in a rich and flavorful Blueberry French Toast Casserole that’s ready to be baked the next morning.

Step 6
When you’re ready to bake, preheat your oven to 350°F. Remove the casserole from the refrigerator and sprinkle the prepared streusel topping evenly over the soaked bread. Bake in the preheated oven for about 45-50 minutes, or until the top is golden brown and the edges are firm. The casserole should be lightly puffed and a little bubbly around the edges—ideal for serving warm to your guests!
