(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

Directions

1. Prepare the Bread: Grease a 9×13-inch baking dish with butter or nonstick spray. Slice the French bread into cubes and spread them evenly in the prepared dish. Scatter the blueberries and cream cheese cubes over the bread.

2. Make the Custard: In a large bowl, whisk together the eggs, milk, cinnamon, brown sugar, and vanilla extract until well combined.

3. Assemble the Casserole: Pour the custard mixture evenly over the bread, ensuring all pieces are soaked. Cover the dish tightly with plastic wrap and refrigerate overnight, or for at least 3 hours.

4. Bake: Preheat the oven to 350°F (177°C). Remove the casserole from the refrigerator and let it sit at room temperature while the oven preheats. Bake, uncovered, for 45–55 minutes, or until the top is golden brown and the center is set.

5. Serve: Let the casserole cool for about 10 minutes before slicing and serving. Optionally, dust with powdered sugar or drizzle with maple syrup.

FAQs

Can I use fresh bread instead of stale bread?

Fresh bread can be used, but slightly stale bread absorbs the custard mixture better, resulting in a more cohesive casserole. To stale fresh bread, cut it into cubes and let it sit out for a few hours or bake at a low temperature for about 10 minutes.

Is it necessary to refrigerate the casserole overnight?

Refrigerating the casserole allows the bread to soak up the custard mixture, ensuring a moist and flavorful dish. While overnight refrigeration is ideal, a minimum of 3 hours is recommended.

Can I make this casserole without cream cheese?

Yes, you can omit the cream cheese or substitute it with mascarpone or ricotta cheese for a different texture and flavor.

How do I prevent the blueberries from sinking to the bottom?

Tossing the blueberries in a small amount of flour before adding them to the casserole can help prevent them from sinking during baking.

Can I use frozen blueberries?

Yes, you can use frozen blueberries without thawing them first. This helps prevent the berries from bleeding into the custard.

Can I prepare the casserole in advance and bake it later?

Absolutely. Assemble the casserole the night before, refrigerate it, and bake it the next morning for a convenient breakfast option.

How do I know when the casserole is done?

The casserole is done when the top is golden brown and the center is set. A knife inserted into the center should come out clean or with a few moist crumbs.

Can I add nuts to the casserole?

Yes, adding chopped nuts like pecans or walnuts can provide a delightful crunch and additional flavor.

Is this casserole suitable for a crowd?

Yes, this recipe serves 8 and can be easily doubled to accommodate more guests.

Can I serve this casserole with toppings?

Absolutely. Serve with maple syrup, powdered sugar, whipped cream, or fresh fruit for added flavor and presentation.
