• Softened cream cheese: Provides creamy richness to balance the tart blueberries perfectly.
• Powdered sugar: Adds smooth sweetness that blends flawlessly into the cream cheese mixture.
• Milk: Moistens and binds the casserole, creating a tender custard soak.

• Blueberries: Fresh and vibrant, they bring juicy bursts of tangy sweetness.
• Cubed French bread: The sturdy yet soft base that soaks up all the custard and flavors beautifully.

• Cinnamon powder: Adds a comforting spice that complements the blueberries.
• Ground nutmeg: Offers a subtle warmth and earthiness to round out the spices.

How to Make Overnight Blueberry French Toast Casserole

Step 1: Prepare the Cream Cheese Mixture

Start by mixing together the softened cream cheese, powdered sugar, 2 tablespoons of milk, and 1 teaspoon of vanilla extract until you get a smooth, creamy consistency. This luscious base is what sets this casserole apart by infusing each bite with richness. Then, gently fold in 1 cup of blueberries so every bite packs a fresh and fruity punch. This combination will lend a delightful texture and balance of flavors within the casserole.

Step 2: Assemble the Bread Layers

Grab a 10×14-inch baking dish and layer the bottom evenly with the cubed French bread. This sturdy bread is perfect for soaking up all the custard goodness without becoming soggy. Spread the cream cheese mixture over this bread layer as if you’re frosting a cake, ensuring it’s evenly covered so every mouthful has that creamy blueberry goodness. Top with the remaining bread cubes to create a beautiful layered effect that will soak in the custard overnight.

Step 3: Prepare and Add the Egg Mixture

In a separate large bowl, whisk together 2 cups of milk, eggs, remaining 1 tablespoon of vanilla extract, cinnamon, and nutmeg until fully combined. This spiced custard mixture is the heart of the casserole—it seeps into the bread and cream cheese, melding all the flavors perfectly. Pour it evenly over the layered bread, making sure every bite is saturated. Finally, sprinkle the remaining cup of blueberries across the top to add bursts of color and flavor on the surface. Cover tightly with aluminum foil and refrigerate overnight.

Step 4: Preheat the Oven

About 30 to 60 minutes before baking, take the casserole out of the fridge to come to room temperature. Preheat your oven to 375°F (190°C). This step ensures even baking and a soft, custardy center with a nicely browned top.

Step 5: Bake the Dish

Place the foil-covered casserole in the oven and bake for 45 minutes. Then remove the foil and continue baking for an additional 30 minutes or until the center sets and the top turns a lovely golden brown. The total baking time of about 75 minutes allows the casserole to develop that perfect texture: creamy inside with a lightly crisp top.

Step 6: Serve and Enjoy

Once baked, let the casserole cool slightly to allow the custard to firm up just enough for clean slices. Then dig in! This dish is a harmonious blend of creamy, fruity, and spiced layers that feels like a warm hug with every forkful. It’s a guaranteed crowd-pleaser that’s as beautiful as it is delicious.

How to Serve Overnight Blueberry French Toast Casserole

Garnishes

Elevate your casserole with a simple dusting of powdered sugar or a drizzle of pure maple syrup. Fresh mint leaves or additional fresh blueberries scattered on top can add a vibrant, fresh contrast that looks as pretty as it tastes. Whipped cream or a dollop of Greek yogurt pairs wonderfully if you want extra creaminess on the side.

Side Dishes

This casserole shines as the star of any brunch and pairs beautifully with light sides. Serve alongside crispy bacon or breakfast sausage for savory balance, or fresh fruit salad to echo the blueberry highlight. A crisp glass of fresh orange juice or sparkling coffee cocktail can make the meal feel extra-special.

Creative Ways to Present

For a festive brunch, consider serving the casserole in individual ramekins. Layer blueberries and cream cheese mixture for a pretty cross-section in each. Alternatively, make mini versions in muffin tins for grab-and-go bites. You can even turn leftover casserole into French toast sticks by slicing and gently pan-frying for a fun twist the next day.

Make Ahead and Storage

Storing Leftovers

Store any leftover Overnight Blueberry French Toast Casserole tightly covered in the refrigerator for up to four days. Keeping it cold preserves the creamy texture and prevents the blueberries from turning mushy while maintaining all those wonderful flavors.

Freezing

This casserole freezes beautifully. For best results, freeze before baking by assembling in a freezer-safe dish wrapped tightly with plastic wrap and aluminum foil. When ready to enjoy, thaw overnight in the fridge and bake as directed. You can also freeze baked leftovers to reheat later.

Reheating

Reheat individual servings gently in the microwave or place the whole casserole in a preheated 350°F (175°C) oven covered with foil until warmed through. To refresh the crispy top, uncover during the last few minutes of reheating for a delightful finish.

FAQs

Can I use frozen blueberries in the Overnight Blueberry French Toast Casserole?

Absolutely! Just be sure to thaw and drain them well to prevent excess moisture from affecting the custard texture.

What type of bread works best for this casserole?

French bread or a sturdy brioche works best because they soak up the custard without becoming too mushy and have a nice structure for layering.

Can I make this casserole gluten-free?

Yes, simply substitute in a gluten-free bread that is sturdy and slightly dense to maintain texture during soaking and baking.

How long can the casserole soak overnight?

It’s best to soak it for at least 8 hours but no more than 24 hours. Soaking too long can break down the bread too much, leading to a soggier texture.

Is it possible to prepare this casserole in the morning and bake the same day?

You can assemble it a few hours ahead and bake it, but overnight soaking really helps the flavors meld and the custard fully soak into the bread for that classic texture.
