A golden baked French toast casserole with warm blueberry sauce spooned over a square.

The fridge does the slow part. You just have to be patient enough to let it.

I'm a smoke-and-coals man, but a crowd of hungry neighbors on a holiday morning calls for something else. This one is slow cooking in its own way. You assemble it the night before, the fridge does the waiting, and in the morning you pour coffee while the oven works. Nobody's flipping anything.

Why I make it for company

My mother Barbara taught me a Southern table is about who shows up. When people show up, I want to sit with them, not stand at a stove. A pan of this on the counter, a pot of blueberry sauce still warm, and the house smells like vanilla and butter. That's a gathering.

Mise en place

30 minutes, and you’re ready to cook.

Ten small steps, all of them done before you ever pour a drop of custard. Line things up in this order and the assembly goes slow and easy.

  1. Gather EquipmentGather a 9x13-inch baking dish, nonstick spray, a large cutting board, a sharp knife, a large mixing bowl, a whisk, a medium saucepan, measuring cups and spoons, and prep containers.
  2. Prepare the Challah BreadCut 12 slice Challah Bread into 1-inch pieces. Divide the bread pieces into two equal portions and place in separate prep containers.
    3 min
  3. Prepare the Cream CheeseCut 1 Two 8-Ounce Packages Cream Cheese ((Or Mascarpone Cheese)) into cubes (or scoop with a small cookie scoop) and place in a prep container.

    30s
  10. Spray and Stage the Baking DishSpray the 9x13-inch baking dish with nonstick spray and set aside. Arrange all prepped ingredients near the work area in the order they will be used: bread portions, cream cheese cubes, blueberries for assembly, eggs in the large bowl, milk, vanilla extract, maple syrup, sugar and cornstarch mixture, water, fresh blueberries for sauce, and butter.

Changing it up

Raspberries or blackberries trade in easily for the blueberries. Brioche works if you can't find challah. For a tangier middle, goat cheese or brie can stand in for the cream cheese. I'd stay with the maple, though.

Common questions

Can I assemble it the night before?
Yes, that's the whole idea. Cover the dish and refrigerate it overnight, at least 8 hours. Take it out half an hour before baking.
How long does it bake?
Bake at 350 degrees F, covered with foil for 30 minutes. Then uncover and bake another 25 to 30 minutes until the center is set and the top is golden.
How many does it serve?
It serves 12. Prep is 25 minutes and cooking is 60, so about 85 minutes of active time in all.
Can I use frozen blueberries?
Fresh or frozen both work. Fresh gives you more color, since frozen berries bleed less into the custard.
What can I use instead of challah?
Pizza dough, crescent rolls or crescent roll dough are listed swaps. In my own kitchen I'd reach for brioche.
Does it contain common allergens?
It contains milk, egg, wheat and gluten. It's nut-free as written, but check your own ingredient labels.

Go on, then

Start tonight. Cube the bread, pour the custard, set the book on top and go to bed. Tomorrow, call everybody to the table and let them smell it first. Fire up something good.
