Ingredients
French Toast Casserole
- 12-15 slices of bread thickly sliced brioche or white bread
- 6 large eggs
- 2 cups whole milk
- ½ cup heavy cream
- ¾ cup granulated sugar
- 1 teaspoon cinnamon
- 2 tbs vanilla extract
Crumble Topping
- 1 cup flour plus up to ¼ cup more if needed
- ½ cup brown sugar
- 1 teaspoon cinnamon
- pinch salt
- ½ cup cold butter cut into tiny chunks
Instructions
Grease a 9x13 pan very lightly with non-stick cooking spray. Set aside.
Cut bread slices into 1 inch chunks and stagger them in the prepared baking dish as even as possible. You may need more or less bread to fill your pan depending on thickness/size.
In a large bowl or measuring cup, whisk eggs, milk, heavy cream, sugar, cinnamon and vanilla together very well until combined. Pour custard mixture evenly over bread pieces trying to moisten every piece as well as you can. Tightly cover with plastic wrap and store in the refrigerator over night.
To make the crumble topping, whisk together flour, brown sugar, cinnamon and salt in a medium bowl. Cut in butter until a coarse meal consistency is achieved. Either cover the bowl with saran wrap or place the mixture into a resealable bag to store in the refrigerator overnight with the pan of french toast.
In the morning, preheat your oven to 350 degrees. Uncover the french toast and evenly distribute the crumble on top.
Bake for 45 minutes - 1 hour depending on how gooey and custard-like you want the center to be.
Once done, serve warm with maple syrup or even just a sprinkle of confectioner's sugar on top.

When I make this recipe I have always cut little one inch cubes of bread…. But I’m starting to think you lay one inch pieces of bread just flat in the 9x13. Can you clarify?

There's really no specific way to prepare it - I just throw the bread pieces in the 9x13 pan in an even layer.

I just tried this today. It was amazing. My family absolutely loved it. My brother and sister-in-law were visiting from Colorado, so I decided to make it and it was a hit. It was all gone and it was delicious.

Looks delicious. I like the crumbly top. ?? The photo of the overnight French toast looks like there are peach slices on the bread. Are there ?
Reply
Jessica says
Nope, no peaches. What you’re seeing is the crust from the bread.

Your pictures look like there are peaches on top under the crumble. Did you put peaches on it?

I found the middle to be a bit bland, I would probably add some cinnamon to the egg mixture. Otherwise it turned out pretty good.

It's even better with challah bread or really just any thick cut bread!

Jessica says
That's good to know! I love challah bread so I may try that.

This looks absolutely delicious! My boys love French toast and my other half makes it on a regular basis, I've never heard of letting it set overnight though - I need to show this to my other half! I like that this version has a crumble to it, such a unique twist to how we usually make it. Thanks for sharing the recipe and method, we need to try it out for ourselves 🙂
