Of all of my breakfast recipes, Overnight Blueberry French Toast is a favorite in my house for Christmas morning. We make it the night before, refrigerate overnight, and then it’s so easy to pull out and put in the oven while we’re opening gifts!

How to Make Blueberry French Toast Casserole:
This blueberry overnight breakfast casserole recipe uses 3 key ingredients that make it awesome: challah bread (my favorite), cream cheese (you can sub mascarpone cheese if you’d like) and blueberries (fresh or frozen). If you cannot locate challah bread, it’s okay to substitute French bread.
Start with adding cubed bread to a greased baking dish. Top the bread with chunks of cream cheese and then blueberries.
More bread is added on top of the cream cheese and blueberries. An egg/milk mixture is poured on top of all of that bread. At this point, you’ll cover it with plastic wrap and refrigerate.
Do you have to let this refrigerate overnight?
It’s covered and refrigerated overnight to let the bread soak up all of that eggy mixture. This is an important step. I like to place a heavy book on top of the plastic wrap- covered casserole so it really gets that bread all down in there in the liquid. You need an overnight soak to really let that egg mixture soak into all of that bread!
In the morning, you can just take the casserole out of the fridge and bake it. I like to take it out of the refrigerator for about 1/2 hour before putting it in the oven.
While it’s baking, you’re going to make a quick and simple, warm blueberry sauce.

Let the blueberry french toast casserole sit for a while before you try to cut into it. You’ll get cleaner slices that way.
The warm blueberry sauce is drizzled on top of warm pieces of the blueberry french toast . And it’s SO GOOD! This would be the perfect breakfast treat to serve for a holiday brunch or family gathering. It’s special enough for that for sure.
I have had this recipe sitting in my email for years… 4 years to be exact! I don’t remember how I came to ask for it. I must have been on Twitter (the big thing back then) tweeting to my friends to send me recommendations for a good brunch casserole for Easter or Mother’s Day.
One of my friends really came through for me because this overnight french toast casserole is a big time winner.
The recipe comes from my friend Janet (an internet friend for many years who I recently met in person!!) She sent me this recipe in an email many years ago… and I’m finally sharing it with you today!
Thank you so much to my friend Janet for sharing this recipe. It’s delicious, and I’m happy to share it with you too. Enjoy!

Overnight Blueberry French Toast
Ingredients
FRENCH TOAST:
- 12 slices (about 1 pound) thick, stale Challah bread (one loaf)
- Two 8-ounce packages cream cheese (or mascarpone cheese)
- 1 cup fresh or frozen blueberries (or maybe a little more)
- 12 large eggs
- 2 cups milk
- 1 teaspoon vanilla extract
- ⅓ cup maple syrup
BLUEBERRY SAUCE:
- 1 cup granulated white sugar
- 2 tablespoons cornstarch
- 1 cup water
- 1 cup fresh blueberries
- 1 tablespoon butter
Instructions
- Spray a 9x13-inch baking dish with nonstick spray and set aside.
- Cut the bread into 1-inch pieces. Place half into the prepared baking dish. Cut the cream cheese (or mascarpone) into cubes (or scoop with a small cookie scoop) and place on top of the bread. Top with the blueberries and then the remaining bread cubes.
- Whisk the eggs in a large bowl. Whisk in the milk, vanilla and syrup until well combined. Pour over the bread cubes. Cover with plastic wrap and refrigerate overnight (I like to place a book on top of the plastic wrap to sink the bread into the liquid). The next morning remove the pan from the fridge 1/2 hour before baking. Preheat oven to 350 degrees F. Remove the plastic wrap, then cover with foil and bake for 30 minutes. Remove the foil and bake another 25 to 30 minutes, or until the center is set and color is golden.
PREPARE THE BLUEBERRY SAUCE:
- In a medium saucepan whisk together the sugar and cornstarch. Add the water and bring to a boil over medium heat. Stir constantly and boil for about 3 minutes. Stir in the blueberries and reduce heat to low. Simmer for about 10 minutes or until the blueberries begin to pop. Stir in the butter until melted. Pour warm sauce over individual servings.
Notes
- I like to use whole milk- it just makes the dish a little bit more decadent all around.
- Mix in chopped fresh, frozen or canned peaches for a peach and blueberry overnight french toast!

can you make this as muffins and if so recipe?
No idea!
This turned out perfect.
I’m making this recipe for the first time for Easter. Can I let it soak 2 nights before baking it? Or should I bake it the day after soaking and then reheat the next day. I needed to make 2 days ahead of time. Thanks
So sorry I missed your message- I was on vacation. Hope it worked out for you!
I took this to a church breakfast and it was devoured! I added a squeeze of lemon to the sauce because I like lemon! This is a real keeper.
This is the best french toast recipe. I use it for every special occasion brunch and it’s a huge hit. Easy and yummy. Thank you!
