• Fresh blueberries: Brings freshness, juiciness, and a pop of beautiful purple color.
• French bread: Sturdy yet soft, perfect for soaking up the custard without falling apart.
• Eggs: The binding element that sets the custard and keeps everything luscious.
• Cinnamon powder: Offers a sweet-spicy warmth that complements the blueberries perfectly.
• Ground nutmeg: A pinch adds depth and a hint of cozy spice to the custard.

How to Make Overnight Blueberry French Toast Casserole

Step 1: Prepare the Cream Cheese Mixture

Start by creating a smooth and creamy base that will make each bite rich and decadent. In a bowl, mix softened cream cheese with powdered sugar, milk, and half of the vanilla extract until perfectly smooth. Then gently fold in one cup of fresh blueberries. Carefully folding in the blueberries prevents them from breaking too much, ensuring you get gorgeous bursts of fruit throughout the mixture.

Step 2: Assemble the Bread Layers

Now it’s time to build your casserole masterpiece. Begin by layering cubed French bread evenly at the bottom of a 10×14-inch baking dish to create a sturdy base. Spread the cream cheese and blueberry mixture over this bread layer. This creamy layer will soak into the bread and add delightful pockets of richness and blueberries. Top this with the remaining bread cubes to form a cozy, multilayered structure ready to soak up the egg custard.

Step 3: Prepare and Add the Egg Mixture

Whisk together milk, eggs, the remaining vanilla extract, cinnamon, and nutmeg in a large bowl until everything is fully combined and frothy. Pour this luscious egg mixture evenly over the layered bread, making sure every cube is fully drenched to guarantee a custardy, tender texture. Finally, sprinkle one cup of fresh blueberries evenly on top, which will bake into the surface, adding juicy jewels as the casserole cooks. Cover tightly with foil and refrigerate overnight, allowing all those flavors to marry beautifully.

Step 4: Preheat the Oven

About 30 to 60 minutes before baking, remove the casserole from the fridge to take the chill off. Preheat your oven to 375°F (190°C). Preheating is key to ensure the casserole bakes evenly, with that perfect delicate crust forming on top.

Step 5: Bake the Dish

Bake the casserole covered with foil for 45 minutes to trap moisture and allow the custard to set gently. Then remove the foil and continue baking for about 30 more minutes until the center is set and the top is delightfully browned. This step is crucial for achieving a gorgeous golden crust without drying out the creamy interior. In total, the casserole will bake for approximately 75 minutes.

Step 6: Serve and Enjoy

Let the casserole cool slightly after baking—a few minutes to relax and finish setting. Then slice into thick, sumptuous squares and serve warm. Each bite offers that perfect blend of creamy custard, sharp cream cheese blueberries, and soft, spiced French bread. It’s utter breakfast bliss that never fails to impress.

How to Serve Overnight Blueberry French Toast Casserole

Garnishes

Top your casserole with a dusting of powdered sugar for a pretty, delicate finish. Fresh blueberries, a drizzle of maple syrup, or a little dollop of whipped cream add delightful texture and sweetness, making it extra special. Toasted nuts like pecans or almonds can also bring a lovely crunch and nutty flavor contrast.

Side Dishes

Since the casserole is already rich and full of flavor, light and fresh sides work best. Serve with crisp bacon or sausage for a savory balance or a fresh fruit salad to complement the blueberry theme. A cup of your favorite coffee or freshly squeezed orange juice rounds out the meal beautifully.

Creative Ways to Present

For a brunch gathering, serve the casserole in a beautiful ceramic dish straight from the oven, letting guests help themselves to warm slices. Or cut it into individual portions and place on plates garnished with fresh mint and extra blueberries for a photogenic presentation. You can even set up a topping bar with syrups, nuts, and fruits to personalize each serving.

Make Ahead and Storage

Storing Leftovers

Store any leftovers in an airtight container in the refrigerator for up to three days. The casserole actually tastes even better after resting as the flavors continue to deepen. To keep the topping nice and fresh, consider adding fresh blueberries or syrup just before serving again.

Freezing

You can freeze leftover portions wrapped tightly in plastic wrap and foil or stored in a freezer-safe container for up to one month. Make sure to thaw overnight in the fridge before reheating to maintain the creamy texture and avoid drying out the bread.

Reheating

Reheat leftovers gently in a 350°F (175°C) oven for about 15-20 minutes or until warmed through. Cover with foil at first to keep moisture, then remove foil near the end to refresh the slightly crisped top layer. A quick zap in the microwave works too if you’re in a hurry, but the oven delivers best texture.

FAQs

Can I use a different type of bread for this casserole?

Absolutely! While French bread is ideal for its sturdy texture and slight chewiness, you can also experiment with brioche or challah. These breads add their own richness and sweetness, but be mindful they may soak up custard more quickly.

Do I have to soak the casserole overnight?

While soaking overnight yields the best results by allowing the bread to absorb all the custard and flavors fully, if you’re short on time, even a few hours in the fridge can work. Just make sure it sits long enough to soak through completely.

Can I use frozen blueberries instead of fresh?

Yes, frozen blueberries can be used! Just thaw and drain them well before mixing in to avoid excess moisture that might make the casserole soggy. Fresh blueberries are preferred for their texture and appearance.

Is this casserole suitable for making ahead for a crowd?

Definitely! That’s the beauty of an Overnight Blueberry French Toast Casserole. You can assemble it the night before, refrigerate, and pop it in the oven the next morning, making it perfect for feeding guests without last-minute stress.

Can I add other fruits or flavors?

Feel free to get creative! Strawberries, raspberries, or sliced peaches would all be delicious substitutions or additions. For extra warmth, you could sprinkle a touch of orange zest or swap nutmeg for allspice.
