Paul said “close enough,” and that became my permission. The pepparkakor filled the house with ginger and cinnamon, and when I looked for something to share here — something that captures that same alchemy of warm spice and sweetness transforming a hard day — this overnight cinnamon roll casserole is the one I kept coming back to. It goes together the night before, which matters, because some mornings you need the oven to do the work while you sit beside someone you love and just breathe. Make it in October. Make it whenever the house needs to smell like something good is coming.
Overnight Cinnamon Roll French Toast Casserole
Prep Time: 20 min + overnight rest | Cook Time: 50 min | Total Time: 1 hr 10 min + overnight | Servings: 8
Ingredients
- 1 loaf (about 16 oz) brioche or French bread, cut into 1-inch cubes (about 8 cups)
- 4 large eggs
- 1 cup whole milk
- 1/2 cup heavy cream
- 1/4 cup granulated sugar
- 2 tablespoons light brown sugar, packed
- 1 1/2 teaspoons pure vanilla extract
- 1 1/2 teaspoons ground cinnamon, divided
- 1/4 teaspoon ground nutmeg
- 1/4 teaspoon fine salt
- 3 tablespoons unsalted butter, softened
- 3 tablespoons light brown sugar, packed (for swirl)
- 1 cup powdered sugar
- 2–3 tablespoons whole milk (for glaze)
- 1/2 teaspoon vanilla extract (for glaze)
Instructions
- Prepare the pan. Grease a 9x13-inch baking dish with butter or nonstick spray. Spread the bread cubes in an even layer in the dish.
- Make the custard. In a large bowl, whisk together the eggs, milk, heavy cream, granulated sugar, 2 tablespoons brown sugar, vanilla, 1 teaspoon cinnamon, nutmeg, and salt until fully combined and smooth.
- Soak the bread. Pour the custard evenly over the bread cubes, pressing down gently so every piece begins to absorb the liquid. Cover tightly with plastic wrap and refrigerate overnight, or for at least 6 hours.
- Make the cinnamon swirl. In a small bowl, mix the softened butter, 3 tablespoons brown sugar, and remaining 1/2 teaspoon cinnamon into a paste. Cover and refrigerate alongside the casserole.
- Preheat and top. When ready to bake, remove the casserole and cinnamon swirl from the refrigerator and let both sit at room temperature for 20 minutes. Preheat the oven to 350°F. Drop small spoonfuls of the cinnamon butter paste across the top of the soaked bread and swirl gently with a knife.
- Bake. Bake uncovered for 45–50 minutes, until the top is golden and set in the center. A knife inserted in the middle should come out without wet custard. If the top browns too quickly, tent loosely with foil after 30 minutes.
- Make the glaze. While the casserole bakes, whisk the powdered sugar, 2 tablespoons milk, and vanilla together until smooth. Add the remaining tablespoon of milk a little at a time until the glaze is pourable but not watery.
- Glaze and serve. Let the casserole rest 5 minutes after baking. Drizzle the glaze over the top and serve warm, directly from the pan.
