French toast for a crowd with zero standing over a hot stove involved might be the biggest breakfast win to ever exist.
I’m talking everything in one pan plus streusel and blueberries are involved, like gee whiz, why isn’t this breakfast every morning??

The answer is because it’s too dang good. Self control ain’t no thing around here.
Did I mention you can totally prep this one the night before? I’m gonna stop now before I pass out from all the winning.
This French Toast Casserole Features…
- Soft French bread cubes and juicy blueberries
- A sweet vanilla custard
- Buttery brown sugar streusel baked on top

Making The Casserole
(scroll down to the bottom of the post for the full recipe)
Ingredients You Will Need
- Eggs
- 2% or skim milk
- Heavy whipping cream
- Maple syrup
- Vanilla extract
- French bread
- Blueberries
- All-purpose flour
- Brown sugar
- Ground cinnamon
- Unsalted butter
Choosing Your Bread
I recommend using a loaf of French bread, ciabatta, challah, or sourdough for this recipe. If you want a milder flavor, go with any of the first three choices but if you want that signature sour flavor you get in some French toasts, give the sourdough a try.
Whatever bread you decide to go with, I recommend you purchase a whole loaf, rather than pre-sliced. This way you’ll be able to control the thickness of the cubes.

Tips for Perfect French Toast Casserole
- Cut bread into 1/2-inch cubes – try to cut the bread into uniform cubes so they get evenly submerged in the custard.
- Whisk eggs well into milk and cream – you don’t want any egg chunks in the casserole.
- Bake French toast at high temperature – this will crisp up the exterior of the French toast, similar to when you cook classic French toast on the stovetop.
- Serve French toast casserole warm – this casserole is best served warm from the oven for the best texture. Don’t forget the powdered sugar and maple syrup on top!
Recipe Variations
Try these ideas for a different twist on this casserole.
- Use another fruit – try raspberries, strawberries, blackberries, or sauteed apples in place of the blueberries.
- Add chocolate – sprinkle casserole with white or semisweet chocolate chips while warm.
- Add nuts to streusel – try adding pecans, walnuts, or almonds to the streusel topping.
Overnight Instructions
This casserole can easily be prepped to soak overnight for easy baking the next day!
Follow the recipe instructions through Step 2, cover casserole dish, and refrigerate overnight or up to 8 hours. The next day, allow casserole to come to room temperature for about 20 minutes then top with streusel and bake according to recipe instructions.

Don’t be surprised when you end up with an empty pan of this casserole! It bakes up so moist in all that wonderful vanilla custard and the little pops of juicy blueberry and buttery streusel in every bite make it absolutely irresistible.
Excuse me while I head back for my third slice.

Can you use anything else if you dont have whole wheat flour? This dish sounds AMAZING
Sarah says
Hi Libby! I haven’t tested this recipe with anything other than white whole wheat flour, but you could most likely sub in all-purpose or whole wheat. Let me know how it turns out!

I want a big helping of this for breakfast! I love that you added a streusel topping, and just look at all of those blueberries!
Sarah says
Thanks so much, girl! This french toast sounds RIGHT up your alley! 😉
Cheryl says
Mmmm this is totally money! I’m all about blueberries in breakfast foods and french toast is *the best* in general anyway! I can only imagine how quickly I’d hop out of bed if I had this waiting for me.. I wonder if you could use maple syrup instead of some of the coconut sugar?
Sarah says
You could totally sub maple syrup in for the coconut sugar! Since maple syrup is sweeter, you’d only need about 1/2 cup or so. 😉

Ooooh, I’m right there with ‘ya dreaming about that Manali! 🙂
