Blueberry Cream Cheese French Toast Casserole
Servings: 8–10
Prep time: 25 minutes
Soaking time: 2 hours or overnight
Bake time: 50–60 minutes
Total: about 3 hours, or overnight + baking
Pan: 9 × 13-inch baking dish
Ingredients
For the casserole
1 large loaf French bread or brioche, preferably day-old — about 8 cups cubed
8 oz (226 g) full-fat cream cheese
2 cups fresh blueberries
8 large eggs
2½ cups half-and-half
or use 2 cups whole milk + ½ cup heavy cream
⅓ cup granulated sugar
2 teaspoons vanilla extract
2 teaspoons ground cinnamon
½ teaspoon salt
1 tablespoon fresh lemon zest
1 tablespoon fresh lemon juice
2 tablespoons maple syrup
2 tablespoons butter, for the pan
Day-old bread is especially useful because it absorbs the custard while retaining its structure rather than becoming excessively mushy.
Cream-cheese filling
For an especially creamy, cheesecake-like result:
8 oz cream cheese, softened
¼ cup powdered sugar
1 teaspoon vanilla
1 tablespoon lemon juice
1 teaspoon lemon zest
Golden topping
2 tablespoons melted butter
2 tablespoons light brown sugar
½ teaspoon cinnamon
Pinch of salt
Blueberry sauce
2 cups blueberries
½ cup granulated sugar
1 cup water
2 tablespoons cornstarch
1 tablespoon lemon juice
1 tablespoon butter
Blueberry sauces made with blueberries, sugar, water and cornstarch are commonly served with this style of casserole.
For decorating, like the photo
½–1 cup fresh blueberries
Powdered sugar, optional
Lemon zest, optional
A little blueberry sauce
Step-by-step instructions
1. Prepare the bread
Cut the bread into approximately 1-inch cubes.
If your bread is fresh rather than stale, spread the cubes on a baking sheet and leave them uncovered for several hours, or bake at 275°F (135°C) for about 15–20 minutes until slightly dried.
Don’t toast them until crunchy—the goal is simply to remove some moisture.
2. Prepare the cream cheese
Beat the softened cream cheese with:
¼ cup powdered sugar
1 teaspoon vanilla
1 tablespoon lemon juice
1 teaspoon lemon zest
Beat until smooth and creamy.
Tip: If your cream cheese is difficult to cut, refrigerate or briefly chill it first. Cubed cream cheese is easier to distribute throughout the casserole.
3. Make the custard
In a large bowl whisk together:
8 eggs
2½ cups half-and-half
⅓ cup sugar
2 teaspoons vanilla
2 teaspoons cinnamon
½ teaspoon salt
1 tablespoon lemon zest
1 tablespoon lemon juice
2 tablespoons maple syrup
Whisk thoroughly until the eggs are completely incorporated.
4. Assemble
Butter a 9 × 13-inch baking dish.
Add approximately half of the bread cubes.
Dot half of the cream-cheese mixture over the bread.
Sprinkle with 1 cup blueberries.
Add the remaining bread.
Add the remaining cream cheese and another 1 cup blueberries.
Pour the custard slowly and evenly over everything.
Press the bread gently down with a spatula so it absorbs the custard.
Don’t crush it—you just want all the bread exposed to the liquid.
5. Soak
Cover the dish and refrigerate for at least 2 hours.
Overnight is even better.
This gives the bread time to absorb the custard throughout the center. Make-ahead/overnight preparation is a common approach for blueberry cream-cheese French toast casseroles.
6. Make the blueberry sauce
While the casserole is soaking, make the sauce.
In a small saucepan whisk together:
½ cup sugar
2 tablespoons cornstarch
1 cup water
Whisk until smooth.
Place over medium heat and bring to a gentle boil.
Cook for about 2 minutes, stirring continuously.
Add:
2 cups blueberries
1 tablespoon lemon juice
Reduce heat and simmer for 5–8 minutes.
Break some of the berries with the back of a spoon, but leave some whole.
Turn off the heat and stir in:
1 tablespoon butter
Cool and refrigerate until needed.
7. Bake
Remove the casserole from the refrigerator while the oven heats.
Preheat oven to 350°F (175°C).
Mix together:
2 tablespoons melted butter
2 tablespoons brown sugar
½ teaspoon cinnamon
Pinch of salt
Drizzle or brush this over the top.
Cover loosely with foil.
Bake for 30 minutes.
Remove the foil and continue baking for another 20–30 minutes.
The top should become deeply golden and the center should be set but still soft and creamy.
Similar recipes use a covered-then-uncovered baking method to cook the center while allowing the top to brown.
8. Get the texture shown in your photo
This is important.
Don’t immediately cut the casserole when it comes out of the oven.
Let it rest for 10–15 minutes.
This allows the custard and cream cheese to firm up.
For an even cleaner, thicker slice like the photograph, allow it to rest 20 minutes.
Then cut into large squares.
🫐 Finish like the picture
Put a piece on a plate and add:
Fresh blueberries
Warm blueberry sauce
A very light dusting of powdered sugar
A little lemon zest
You can also add a spoonful of whipped cream or vanilla yogurt.
The contrast of the warm creamy casserole + cold fresh blueberries + warm berry sauce is excellent.
⭐ Important tips for success
Don’t use overly fresh, soft bread
Fresh bread can absorb too much liquid and become mushy.
Best: day-old French bread, brioche, challah, or a sturdy baguette.
Don’t drown the bread
Pour the custard gradually and press the bread gently into it. The bread should be saturated, but there shouldn’t be a huge pool of liquid sitting underneath.
Fresh or frozen blueberries?
Both work.
For fresh blueberries, simply rinse and dry them thoroughly.
For frozen blueberries, don’t completely thaw them first. Tossing frozen blueberries with a little flour can also help reduce excessive color bleeding.
Want it more like cheesecake?
Use:
12 oz cream cheese instead of 8 oz
¼ cup powdered sugar
Extra lemon zest
Brioche instead of French bread
Want it less sweet?
Reduce the casserole sugar from ⅓ cup to ¼ cup and omit the powdered sugar topping.
Nut & Allergy Information
This recipe does NOT require nuts.
There are no peanuts, almonds, walnuts, pecans, cashews, pistachios, hazelnuts, or other tree nuts in the recipe as written.
However, check packaged ingredients—particularly bread, cream cheese, vanilla, and any prepared toppings—for allergen statements if you’re cooking for someone with a nut allergy.
Common allergens
Ingredient Potential allergen
Bread/brioche Wheat/gluten; sometimes milk/egg
Cream cheese Milk/dairy
Eggs Egg
Half-and-half Milk/dairy
Butter Milk/dairy
Cornstarch Generally gluten-free
Blueberries No major common allergen
Cinnamon Usually fine, but individual sensitivities are possible
Gluten-free version
Use a sturdy gluten-free French-style bread or brioche and verify that all packaged ingredients are certified/labelled gluten-free.
Dairy-free version
Use:
Dairy-free cream cheese
Unsweetened plant milk
Dairy-free butter
The flavor and texture will change somewhat, but it works.
Egg-free version
This recipe is much harder to convert because eggs provide most of the custard structure. I’d recommend using a purpose-built egg-free French-toast custard rather than simply omitting the eggs.

Q&A
Can I make this the night before?
Yes—and that’s one of the best ways to make it. Assemble it, cover it and refrigerate overnight. Bake the following morning. Overnight preparation is specifically recommended for several versions of this casserole.
Can I freeze it?
Yes. For best quality, freeze the assembled casserole before baking, tightly wrapped. Thaw overnight in the refrigerator before baking.
The blueberry sauce can also be frozen separately.
Can I use frozen blueberries?
Yes. They work very well. Keep them frozen when assembling if possible.
Why is my casserole soggy?
Usually one of three things:
Too much custard
Bread was too fresh
It wasn’t baked long enough
The center should be creamy, but not liquid.
Why is the middle still wet?
Bake another 5–10 minutes. If the top is already dark, cover it loosely with foil.
Remember that the center continues to set while resting.
Why did my blueberries turn the casserole purple?
That’s normal. Blueberries release their juice during baking.
If you want more distinct white-and-blue layers like the photograph, use fresh blueberries, distribute them in pockets rather than stirring them into the custard, and avoid crushing them during assembly.
Can I use strawberries or raspberries?
Absolutely. A combination of blueberries + raspberries is particularly good.
Can I use lemon curd?
Yes. Spread a few tablespoons between the bread and cream cheese layers for a stronger lemon-blueberry flavor. Modern versions of this casserole sometimes pair blueberries with lemon curd and a blueberry-lemon sauce.
Can I make it without the blueberry sauce?
Yes. Fresh blueberries and maple syrup are enough. The sauce simply gives you the dramatic purple topping shown in the photo.
How do I get that very golden top?
Use the butter/brown-sugar topping and bake uncovered during the second half. For extra browning, you can briefly broil it for 30–60 seconds, but watch it continuously.
How do I get slices as thick as the picture?
Use a little more cream cheese, don’t over-soak the bread, bake until the center is set, and let it rest 15–20 minutes before slicing.
How long does it keep?
Refrigerate leftovers in a sealed container for 3–4 days.
How should I reheat it?
For the best texture, reheat individual portions at 325°F (165°C) until warm, rather than microwaving for a long time.
Is it breakfast or dessert?
Both. It’s technically a breakfast/brunch casserole, but with the cream cheese, blueberries and sauce, it works very well as a dessert too. Similar recipes explicitly describe it as suitable for either breakfast or dessert.
What makes this different from regular French toast?
Instead of soaking and frying individual slices, everything is assembled in one dish and baked together. That creates the soft cheesecake-like center and browned top visible in your photo.
Can I make it less sweet?
Yes. Reduce the sugar and serve the blueberry sauce separately. The blueberries and cream cheese provide plenty of flavor without making the casserole extremely sweet.
My recommended version for the exact look
For the closest visual result to your photograph, I’d use brioche + 12 oz cream cheese + fresh blueberries + lemon zest + cinnamon, bake at 350°F, and let it rest for 20 minutes before cutting. Then pile fresh blueberries over each serving and spoon the thick blueberry sauce over the top.
