Overnight Blueberry French Toast

Here’s a delicious recipe for a spring or summer brunch:  Overnight Blueberry French Toast

Overnight Blueberry French Toast Recipe
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, but I’ve never actually met her in person!!)  Janet is a majorly talented birthday and wedding cake baker and designer – Luv and Buttah – in Phoenix, AZ.  She sent me this recipe in an email four years ago… and I’m finally sharing it with you today!

Overnight Blueberry French Toast 2

This blueberry overnight breakfast casserole recipe uses 3 key ingredients that make it awesome:  challah bread (my favorite), mascarpone cheese (you can sub cream cheese if you’d like) and blueberries.

An egg/milk mixture is poured on top of all of that bread.  It’s covered and refrigerated overnight to let the bread soak up all of that eggy mixture.

In the morning, you can just take the casserole out of the fridge and bake it.  While it’s baking, you’re going to make a quick and simple, warm blueberry sauce.

The blueberry sauce is drizzled on top of warm pieces.  And it’s SO GOOD!  Thank you so much to Janet for sharing this recipe.  I’m glad I remembered it!  This would be the perfect breakfast treat to serve for an Easter or Mother’s Day brunch.

Yield: 10 to 12 servings

Prep Time: 25 minutes

Cook Time: 1 hour

Overnight Blueberry French Toast


French Toast:

  • 12 slices thick stale Challah bread
  • Two 8-ounce packages cream cheese (or mascarpone )
  • 1 cup fresh blueberries (maybe a little more)
  • 12 large eggs
  • 2 cups milk
  • 1 teaspoon vanilla extract
  • 1/3 cup maple syrup


  • 1 cup granulated white sugar
  • 2 tablespoons cornstarch
  • 1 cup water
  • 1 cup fresh blueberries
  • 1 tablespoon butter


  1. Spray a 9x13-inch baking dish with nonstick spray and set aside.
  2. Cut the bread into 1-inch pieces. Place half into prepared baking dish. Cut  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 remaining bread cubes.
  3. 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.
  4. While the french toast is baking, prepare the 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.
*I like to use whole milk- it just makes the dish a little bit more decadent all around. *Mix in chopped fresh peaches for a peach and blueberry overnight french toast!

    I’ve had a lot of overnight french toast in my day, but NEVER with cream cheese!  This looks so fluffy and gooey all at the same time, and I love the blueberries!

    I don’t like blueberry but I love this recipe. Looks so delicious and mouth watering.  Can you suggest any alternative for blueberry?

      Try another kind of berry! Raspberries might be good!

    I can’t find Challa bread Is there another bread I can substitute with?

    • April 8th, 2015 @ 5:13 PM

      Another egg bread or brioche will work.

    I first had this wonderful casserole about 6 yrs ago aa women’s conference.  There were well over 100 people being served.  I thought for sure it must have been catered only to find out the church volunteers had made it.  I got the recipe and love it.  So easy and delicious.  I like to serve mine with a side of breakfast sausage to balance out the sweet with something spicy.

    This was easy and delicious. Thanks for sharing!

    That looks amazing – more like a pudding than a breakfast, but that won’t stop me!

    I think that I will definitely give it a try – but I think that, per your tip in the comments section, I’ll have to use Brioche rather than Challa bread as I haven’t seen that in my local supermarket here.

    This looks amazing. I enjoy french toast every Sunday, but I often work late and dont wake up in time to make it for my roommates. I’m excited to try this recipe instead.

    We are making this tonight can’t wait! But I was wondering we only have king’s Hawaiin bread would that work? Also do you know approximately how many cups of bread cubes I would need to equal the twelve slices of challah bread? Thank you so much for this recipe, Patty

    • July 31st, 2015 @ 6:59 AM

      I’m sure that would be fine. Not sure on the bread cubes… I’d just kind of eyeball it as you fill up the pan with bread.

    Everyone needs this recipe in their recipe box! #yum

    Why does it say to preheat oven the day before, when you’re assembling? And an hour for Cook time, yet in directions 25-30 minutes? I don’t want to mess it up! Thanks!

    • December 16th, 2015 @ 4:12 PM

      sorry- yes, preheat the next day. I will change that in the instructions, thanks! In the instructions is says to bake for 30 minutes with foil on, then an additional 30 with foil off.

    This is a great recipe! I’m so bummed my grocery store doesn’t sell Challah (apparently it didn’t sell well) anymore. I use Brioche and I use whatever berries are seasonally available. Out of all the combinations I love blackberries, if I really want to impress I add peaches! Thank you so much for this!

    Way Way Way WAY too much cream cheese!  And we like cream cheese in our house.  Next time I will only use 1-8 oz pkg.  really looked forward to this Easter morning…will tweek recipe and try again.
