How To Make Sourdough French Toast Baked Casserole
Step 1: cut the bread
First preheat the oven to 350 degrees F.
Then slice the loaf of bread, then cut the sliced bread into approximately 1-inch cubes. Set the cubes of cut bread aside.



Step 2: make the egg mixture
In a large mixing bowl, add your eggs and milk. Whisk them thoroughly.
Next in the same bowl bowl add the cinnamon, brown sugar, and vanilla, mix them together.



Step 3: mix together
Place the cut bread cubes into the egg mixture, and gently stir until all of the bread is coated in eggs. Set aside.



Step 4: make the topping
In a clean mixing bowl, add your melted butter, flour, brown sugar, cinnamon, and salt. Whisk together.



Whisk until combined. The mixture will be clumpy.



Step 5: bake it
Prepare your casserole dish by rubbing it with oil, butter or spraying it with cooking spray.
Pour the egg and bread mixture into the casserole dish. Spread it into an even layer.
Sprinkle the topping evenly over the entire top of your casserole.


Place the french toast casserole into the preheated oven, and bake for approximately 20-35 minutes, or until the top is golden brown and the internal temperature is 165 degrees F. Please note that the cooking time may depend on your specific oven.
Remove it from the oven and let it rest for a few minutes before serving.
Step 6: serve it
Serve the sourdough french toast casserole with a drizzle of maple syrup, some fresh fruit and stabilized whipped cream if desired. Serve after it has set for 5-10 minutes and enjoy!

Sourdough French Toast Bake Tips, Tricks and FAQs
What is the best bread to use for this recipe?
There are several options when it comes to choosing your sourdough bread to use in this recipe. From homemade fresh bread, to day-old bread, to stale bread, or store bought sourdough bread. Then there’s crusty sourdough bread, or soft sourdough sandwich bread.
The truth is that you really can use any of these types of sourdough bread for your sourdough French toast casserole. The type of bread you use will slightly change the outcome of the breakfast bake, but they are all delicious.
If you choose to use crusty bread I would highly recommend cutting the crust off before adding it to your casserole. In my opinion, the best sourdough bread to use is your basic bread recipe made using your Dutch oven.
How to Make Ahead
This recipe is also the perfect make-ahead breakfast. You can do this by completely preparing it and assembling the casserole. Then cover it and put it in the fridge overnight. Then it’s ready to bake the next day.
