How to make Overnight French Toast Casserole:

Combine and Refrigerate: Butter the bottom and sides of a 9×13” pan. Slice bread into 1 inch chunks and add to dish. Whisk eggs in a large bowl and add cream, milk, brown sugar, cinnamon, salt, and vanilla. Pour over cubed bread and gently toss to coat. Add to pan, cover, and refrigerate overnight.

Make Topping: Stir together brown sugar, white sugar, cinnamon, and nutmeg. Cut cold butter into chunks then add to the bowl. Use a pastry cutter or your hands to combine until crumbly. Refrigerate overnight.

Bake: Sprinkle topping on top of casserole, then bake at 350°F (180°C) for 40-50 minutes, until golden on top. Let the baked french toast casserole cool for at least 10 minutes befoer serving. I think it's sweet enough without syrup, but you could serve with homemade syrup, maple syrup, or whipped cream on top.

I’ve been making French toast casserole for years, but I’ve never been completely happy with the various recipes. I’ve been looking for a custard consistency. This recipe hit it out of the park. Wow! So good. Mom said it was the best (and you know how moms can be frugal with compliments!😂). This will more be my go to recipe!!

Do I need to let the French toast bake sit out to room temperature or do I just put it in straight from the fridge?

You can bake it straight from the fridge, no need to bring it to room temperature first.

Can you use stale French bread? Will the eggs revive it?

This sounds really good! I’m guilty of burning the pan when I make French Toast, and this seems like it is an easier way to make it.
