Instructions

Preheat the oven to 350°F.

Spray a 9x13-inch baking dish liberally with nonstick cooking spray.

Cut bread into 1-inch cubes and transfer to a large mixing bowl. Set aside.

In a large mixing bowl, combine eggs, sugar, milk, vanilla extract, lemon zest and salt and whisk until smooth. Add to bread cubes, then add blueberries, and fold with a rubber spatula.

Transfer bread mixture to prepared baking dish.

Bake French toast on middle rack of oven until it is golden brown on top and a toothpick inserted in the center of a piece comes out clean, 45-50 minutes.

Check to see that French toast is done. Remove from oven or add time as needed.

Allow French toast to cool in dish for at least 10 minutes. Prior to serving, plate toast (cut as desired), then sift powdered sugar over the top. Refrigerate leftovers for 2-3 days.

Tips & Tricks (5)

Bread Selection Secrets 🍞
Use day-old challah that's slightly stale, as it absorbs the custard mixture better without becoming mushy, creating the perfect texture for your French toast casserole.
Blueberry Distribution Magic 🫐
Gently fold blueberries into the casserole just before baking, and lightly dust them with a bit of flour to prevent sinking and ensure even distribution throughout the dish.
Lemon Zest Intensity Hack 🍋
Microplane your lemon zest directly into the egg mixture to release the essential oils and maximize the bright, citrusy flavor throughout the entire casserole.
Overnight Prep Perfection 🌙
Assemble the casserole the night before and refrigerate, allowing the bread to fully absorb the custard and intensify the flavor profile for a more delicious brunch dish.
Golden Brown Topping Trick 🌞
If the top isn't browning evenly, cover loosely with foil for the first 20 minutes of baking, then remove to allow the surface to achieve a perfect golden-brown color.
