Ingredients

For the Casserole

• 1 pound French bread, cut into cubes
• 6 extra-large eggs
• 3 cups whole milk
• 1 tablespoon vanilla extract
• 1/2 cup granulated sugar
• 1 tablespoon ground cinnamon
• 1/2 cup fresh or frozen blueberries
• Soft butter or cooking spray for greasing the dish

For the Cinnamon Butter Topping

• 4 tablespoons melted butter
• 1 teaspoon ground cinnamon
• 3 tablespoons light brown sugar

Optional Toppings

• Powdered sugar
• Maple syrup
• Fresh berries

Instructions

Cut the French bread into bite-sized cubes and place them into a large zip-top bag or mixing bowl.

In a small bowl, combine the granulated sugar and cinnamon. Sprinkle the mixture over the bread cubes and toss well so every piece is coated evenly.

In a separate large bowl, whisk the eggs until light and fluffy.

Add the vanilla extract and slowly whisk in the milk until fully combined.

Grease a baking dish with butter or cooking spray.

Spread the bread cubes evenly into the dish. Scatter the blueberries throughout the bread mixture.

Slowly pour the egg mixture over the bread, making sure all the pieces are moistened.

Cover the dish and refrigerate for at least 1 hour or overnight for best flavor and texture.

Preheat the oven to 350°F.

In a small bowl, mix the melted butter, brown sugar, and cinnamon together. Drizzle the mixture evenly over the casserole.

Cover loosely with aluminum foil and bake for 20 minutes.

Remove the foil and continue baking for another 25 minutes until the top is golden brown and slightly crisp.

Allow the casserole to cool for about 10 minutes before serving.

Dust with powdered sugar and drizzle with maple syrup if desired.

Notes and Tips

• French bread works especially well because it absorbs the custard without becoming mushy.
• Slightly stale bread gives the best texture for casseroles like this.
• You can substitute blueberries with strawberries, raspberries, bananas, apples, or raisins.
• For extra richness, add a splash of heavy cream to the custard mixture.
• Letting the casserole rest before baking helps the bread absorb all the flavor evenly.
• Serve with crispy bacon or sausage for a complete breakfast spread.
