Overnight Blueberry French Toast Casserole

This simple make-ahead casserole is kind of like a blueberry pie covered in French toast. Buttery, breakfast-y goodness.

The other day Eric says to me, “Karen, I have something very important to show you.” He hooks the computer to the TV and pulls a trailer up from Youtube. “Are you ready for this?”  Uh…I guess?

STAR WARS. We watch it. And then we watch it one more time. And then we watch it again, but this time we pause it on every scene (yes, really) so that we can analyze the characters and try to figure out exactly who BB-8 might be (R2-D2’s droid-baby??)

I ask Eric who he thought the girl was, Luke’s daughter or Han and Leia’s.

“What girl?”

“The girl, the clear main character, the girl whose face they did a close up on like 3 times in a 2 minute trailer, what do you mean what girl?”

“I didn’t see a girl.”

I think he was distracted by all the X-wings.

Are you guys into Star Wars? My family was totally into it growing up. In high school I had a 10×10 foot painting of the Millennium Falcon fleeing the Death Star (complete with glow-in-the-dark-paint) stapled to the ceiling over my bed. (My sister’s friend painted it as the backdrop of a skit they performed at a summer camp.)

The night before my other sister’s wedding was the day that Episode I came out, and we ALL went to see it together, bride and groom included. What better way to celebrate eternal matrimony than with epic galactic tales of good versus evil?

Even though I love Star Wars, I don’t consider myself a True Fan. There are no Storm Trooper costumes hidden in my closet, thankyouverymuch. I have SOME dignity.

So Mother’s Day is coming up! May 10, in case you were about to google. Since many of you ARE the mom, I have a recipe for you to print out and tape to someone’s forehead. Hey, no shame here ladies, sometimes your just gotta get er done. Even your own pampering.

My sister-in-law’s kids made her this casserole last year for Mother’s Day and I’ve been meaning to make it ever since, because even the leftovers that I tried were so good. This is not French Toast with some blueberries, this is basically blueberry pie with some French Toast on top. It’s AMAZING.

It’s the perfect make-ahead dish, make it the night before and then throw it in the oven in the morning. If you are in a rush though, you don’t have to let the bread soak ALL night–3 hours worked fine for me.

Overnight Blueberry French Toast Casserole

Yield: Serves 6


  • 8 ounces French bread (I used half of a 1-pound loaf)
  • 4 eggs
  • 1/2 cup milk
  • 1/4 teaspoon baking powder
  • 1 teaspoon vanilla
  • 4 and 1/2 cups blueberries*
  • 1/2 cup sugar
  • 4 teaspoons cornstarch
  • 2 teaspoons cinnamon
  • 2 tablespoons butter, melted (I recommend Land O'Lakes )
  • powdered sugar, to garnish


  1. Slice the French bread diagonally into 10-14 slices, each one about 1/2 or 3/4 inch thick.** Arrange in a single layer in a 9x13 inch dish.
  2. In a medium bowl, whisk together eggs, milk, baking powder, and vanilla. Pour slowly over the bread, making sure to get all the bread wet. Turn the slices over and saturate them. Cover completely and chill overnight, or at least a couple hours.
  3. When you are ready to bake, preheat the oven to 425 degrees. Grease a new 9x13 inch pan.
  4. Combine blueberries, sugar, cornstarch, and cinnamon in the greased pan. Stir until combined, then spread it out evenly.
  5. Place the bread wettest side down on top of the blueberries in a single layer. Brush with the melted butter.
  6. Bake in the preheated oven for 24-26 minutes, or until golden brown.
  7. Sprinkle with powdered sugar and serve immediately!


*I used frozen blueberries, didn't thaw them at all.

** I sliced mine a little thicker and put mine into a 2-quart pan. Whatever floats your boat.

    If my husband offers to make a Mother’s Day breakfast, I’m going to show him this recipe. It looks delicious!! I saw every Star Wars Movie when they first came out. Can’t wait to see the new one!

  2. Alissa says

    Thanks for this recipe Karen! I’m not a big French toast girl, but my husband is, and I’m excited to try this this weekend! And, uh, yes, I DO love Star Wars, and I’m just like you, a fan, but not exactly going to dress up as Yoda for the next premier or anything haha! LOVED those movies as a kid though and once upon a time had a fully Star Wars themed bedroom.

    I made this for a special family brunch this morning…..so delicious! I spooned a few dollops of lemon curd over the blueberries before baking and served with fresh lemon slices. Yum!!

  4. Julie @ Cooks with Cocktails says

    French toast is a favorite around here, but I have never tried overnight french toast! I am going to change that this weekend…. Thanks so much for the recipe it looks amazing!

    I just made this for Mother’s Day brunch for my family (6 adults 4 children) and doubled the recipe. It was fantastic and such a nice way to do brunch for a larger group of people. I have celiac disease so I used udi’s gluten free French bread/baguettes. I cut the bread in one to one and a half inch slices. I was a bit worried about the bread but it really was great. Thank you for the recipe and I hope other people suffering from celiac disease will find this recipe and adapt it.
