Let’s jump into the ingredients and the easy steps to create this delightful dish.
Ingredients
- 1 loaf day-old French bread, cubed
Using day-old bread helps absorb the custard mixture better, preventing a soggy texture. French bread provides a beautiful balance of crustiness and softness, enhancing the overall texture of the casserole. - 8 oz cream cheese, softened
Cream cheese adds creaminess and richness to the casserole, creating a luxurious mouthfeel. Softened cream cheese blends well with the other ingredients, ensuring every bite is smooth and decadent. - 1 cup blueberries, fresh or frozen
Blueberries are the star tart element in this dish, adding flavor, color, and nutritional value. Their natural sweetness complements the creamy and eggy layers beautifully. - 1 cup powdered sugar
Powdered sugar sweetens the cream cheese mixture and provides a subtle, gentle sweetness. It also helps achieve a smooth consistency when blended. - 1 tbsp vanilla extract, split
Vanilla extract enhances the overall flavor profile, adding warmth and depth. Splitting it between two components allows for a rounded vanilla taste throughout the dish. - 2 tbsp whole milk
Whole milk contributes to the richness of the cream cheese mixture. The additional fat adds to the overall creaminess, ensuring it blends smoothly. - 6 large eggs
Eggs are the main binding ingredient that gives the casserole its structure and helps it rise during baking. They also enrich the flavor, making the dish more satisfying. - 2 cups whole milk
Adding milk to the egg mixture creates a custard-like base that envelops the bread and blueberries, giving the casserole a moist texture. Whole milk also contributes to a creamy mouthfeel. - 1 tsp ground cinnamon
Cinnamon provides a warm, cozy flavor that pairs perfectly with both the blueberries and the custard. Its aromatic qualities enhance the overall sensory experience of the casserole. - 1/2 tsp ground nutmeg
Nutmeg adds a subtle spice that rounds out the flavor profile, adding depth and complexity. A little goes a long way, making it a perfect complement to cinnamon.
Directions & Preparation
Step 1: Prepare the Cream Cheese Mixture
Start by beating the softened cream cheese until smooth. Then, mix in the powdered sugar, vanilla extract, and whole milk until you achieve a creamy consistency. This step is crucial; it ensures that the cream cheese will blend seamlessly into the casserole, creating pockets of creamy goodness throughout the dish.
Step 2: Add Blueberries to Cream Cheese Mixture
Gently fold in the blueberries into the cream cheese mixture. This step is important because it evenly distributes the blueberries without breaking them. Keeping them whole allows for a burst of flavor in each bite, enhancing both the aesthetic and taste of the final casserole.
Step 3: Assemble the Bread Layers
Layer half of the cubed French bread in the bottom of a greased casserole dish. Spread the cream cheese and blueberry mixture over this layer. Then, add the remaining cubed bread on top. This step is about creating the structure of the casserole, ensuring that each layer is well-defined and that the flavors meld beautifully as it bakes.
Step 4: Prepare the Egg Mixture
In a large mixing bowl, whisk together the eggs, whole milk, vanilla extract, cinnamon, and nutmeg until fully combined. Pour this mixture evenly over the assembled bread layers in the casserole dish. This egg mixture acts as the custard that binds the bread and blueberries together, creating a rich texture that contrasts nicely with the cream cheese.
Step 5: Cover and Refrigerate Overnight
Cover the casserole with plastic wrap and refrigerate overnight. This step allows the bread to soak up the custard mixture fully, ensuring that every piece of bread is saturated and full of flavor. It also makes the morning preparation quick and easy!
Step 6: Preheat the Oven
The next morning, preheat your oven to 350°F (175°C). Preheating is crucial as it ensures that the casserole bakes evenly and rises properly. A uniform temperature will help set the custard and create a beautifully golden top.
Step 7: Bake the Casserole
Remove the plastic wrap and bake the casserole for 35-40 minutes until it is puffed and golden brown on top. Baking brings all the flavors together, intensifying the sweetness of the blueberries and creating a lovely, soft texture. Keep an eye on it towards the end to prevent over-baking, which can lead to a dry casserole.
Step 8: Cool and Serve
Once baked, allow the casserole to cool for a few minutes before slicing and serving. This short cool-down period helps the casserole set further, making it easier to portion and serve. Serve with a dusting of powdered sugar or a drizzle of maple syrup for added sweetness.

Versatility of Blueberries
While this recipe highlights the delightful blueberries, don't hesitate to experiment with seasonal fruits. Cherries, strawberries, or even mixed berries can create a vibrant twist on this classic. Keeping the proportions and technique the same ensures that you still achieve that desirable balance of flavors and textures, making it a versatile staple for any season.
The Role of Day-Old Bread
Using day-old bread is a game changer for this casserole. It has lost some moisture compared to fresh bread, allowing it to soak up the liquid custard mixture without becoming overly soggy. This texture is what gives the casserole its delightful structure. If you only have fresh bread, lightly toasting it before use can also help improve absorption.
Customizing Sweetness Levels
Adjusting the sweetness of the casserole is easy; simply modify the amount of powdered sugar or incorporate different sweet toppings. Consider adding maple syrup, honey, or even a glaze if desired. While the recipe calls for a specific amount, your taste preferences can dictate how sweet or subtle the final dish will be.
FAQs
What should I do if the casserole turns out too dry?
If your casserole is too dry, it may have baked too long, or the bread didn't absorb enough custard. To rescue it, serve it with extra syrup or a creamy sauce to add moisture back into each serving.
Can I scale down the recipe for smaller servings?
Yes! You can easily scale the recipe by halving all ingredients and using a smaller baking dish. Adjust the baking time to ensure even cooking, keeping an eye on it towards the end.
How can I make the casserole extra indulgent?
To elevate your casserole, consider adding a layer of chocolate chips or nuts along with the blueberries. You might also top it with a streusel mixture for a delightful crunch.
Is there a way to reduce the sweetness of the cream cheese mixture?
Absolutely. To lower the sweetness, reduce the amount of powdered sugar in the cream cheese mixture or substitute it with a natural sweetener like honey or agave.
What if I want to add spices other than cinnamon and nutmeg?
Feel free to experiment with spices like cardamom or ginger! Just keep in mind that spices can be potent, so use them sparingly to ensure the flavors harmonize well.
Can I use a different type of milk?
Yes, you can substitute any milk for whole milk. Options like almond, oat, or 2% milk work fine, but they may alter the richness slightly.
