Blueberry French Toast Casserole

This Blueberry French Toast Casserole layers stale sourdough or challah cubed bread with fresh blueberries soaked in an egg and milk custard infused with cinnamon and lemon zest. After an overnight soak in the fridge, a brown sugar, cinnamon, and butter topping is drizzled over the assembled casserole before baking until golden and crunchy on top, offering a tender and flavorful breakfast or brunch option that balances sweet, fruity, and spiced elements in a comforting dish.

Description

The Blueberry French Toast Casserole brings together stale cubes of French bread mixed with fresh blueberries and soaked in a custard blend of eggs, whole milk, sugar, lemon zest, cinnamon, and salt. The lemon zest adds brightness, while the cinnamon provides warm spice notes that complement the natural sweetness of the blueberries. Refrigerated for several hours or overnight to allow the bread to absorb the custard fully, this preparation results in a custardy interior and a tender texture throughout.

The casserole is topped with a mixture of melted unsalted butter, brown sugar, cinnamon, and salt before baking at 375°F until the surface turns golden brown and crisp. This process creates a pleasantly crunchy top layer that contrasts with the soft soaked bread beneath. Letting the casserole cool slightly before serving helps it set and improves texture.

Serve the casserole with extra fresh blueberries, a dusting of powdered sugar, and maple syrup for added sweetness and moisture. This dish works well for a communal breakfast or brunch and can be prepared in advance for convenience.
