Overnight Cinnamon Roll French Toast Casserole Recipe tastes like gooey cinnamon rolls met custardy baked french toast with crackly, caramelized edges and a swirl of warm spice. It suits holiday mornings, weekend brunch, and any time you need a make ahead crowd-pleaser; total time lands around 9 hours including the chill, with about 20 minutes hands-on. I pull this out when my twins sleep late and the coffee needs a co-star.
Overnight Cinnamon Roll French Toast Casserole Recipe
You set it up at night, then bake it off in the morning while the house wakes up. The custard soaks in, the top turns golden, and the kitchen smells like a bakery without a 5 a.m. alarm.
It feeds a crowd, brings kid-and-adult approval, and works with bread cubes or shortcut cinnamon roll dough. Leftovers reheat beautifully, which might qualify as a weekday miracle.
“I prepped it the night before a baby shower. The center baked silky, the edges caramelized, and I actually enjoyed my coffee hot. Five stars from my brunch crew.”
Ingredients You Need
- 1 pound day-old brioche or challah, cut into 1-inch cubes
- Shortcut: Use 2 tubes refrigerated cinnamon roll dough (12–13 oz each), quartered; drizzle with the included icing after baking and reduce brown sugar in custard to 1/4 cup
- 8 large eggs
- 1.5 cups whole milk
- 1 cup heavy cream
- Swap: Use 2.5 cups half-and-half instead of milk plus cream
- Dairy-free: Use full-fat oat milk or almond milk; add 1 tablespoon cornstarch to help custard set
- 1/2 cup packed light brown sugar
- Reduce to 1/4 cup if using canned cinnamon rolls
- 2 teaspoons pure vanilla extract
- 2 teaspoons ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/2 teaspoon fine sea salt
- 4 tablespoons unsalted butter, melted, plus more for the dish
- Optional crunch: 1 cup chopped pecans or walnuts
- Optional orange twist: 1 teaspoon fresh orange zest
- Maple syrup for serving
Cream cheese icing option if not using canned-roll icing:
- 4 ounces cream cheese, softened
- 3/4 cup powdered sugar
- 1 teaspoon vanilla
- 2–3 tablespoons milk to thin
Equipment:
- 9×13-inch baking dish
- Large mixing bowl and whisk
- Serrated knife
- Small bowl for icing
- Plastic wrap or foil
- Sheet pan to catch drips
Quick Tips & substitutions
You can dial this in with a few pro moves and smart swaps.
- Use day-old bread so the cubes drink in the custard instead of sinking into mush.
- Press the cubes down after you pour the custard so every bite soaks evenly.
- Tent with foil for the first part of baking to prevent over-browning, then uncover to finish.
- Bake until the center jiggles slightly but does not slosh; aim for 175–185 F in the middle.
- Want less sugar? Skip the streusel and rely on cinnamon plus a light drizzle of maple syrup.
- Using canned cinnamon rolls speeds things up; reduce the custard sugar and shorten bake time by 5–8 minutes.
- No cream on hand? Use all half-and-half or all whole milk plus 2 tablespoons melted butter for richness.
- Dairy-free path: use plant milk, dairy-free cream cheese for icing, and brush the top with coconut oil.
- Crowd control: build two pans at once and freeze one unbaked for a future brunch.
How to Make Overnight Cinnamon Roll French Toast Casserole
Prep Time 20 minutes
Cook Time 45 to 55 minutes
Total Time About 9 hours including the overnight chill
- Butter a 9×13 baking dish. Add the bread cubes or quartered cinnamon roll dough in an even layer.
- Whisk the eggs, milk, cream, brown sugar, vanilla, cinnamon, nutmeg, and salt until smooth. Pour the custard evenly over the bread. Press the cubes down with the back of a spoon so they soak.
- Sprinkle nuts over the top if using. Drizzle the melted butter over everything.
- Cover tightly with plastic wrap or foil and refrigerate 8 to 12 hours. The bread will drink in the custard while you sleep.
- Heat the oven to 350 F. Set the dish on a sheet pan. Uncover and tent loosely with foil.
- Bake 25 minutes, remove the foil, then bake 20 to 30 minutes more until the top turns golden and the center sets with a slight jiggle. If the top browns too fast, tent again near the end.
- For icing, whisk cream cheese, powdered sugar, vanilla, and enough milk to reach a drizzle. Let the casserole rest 10 minutes, then drizzle the icing or the packet from canned rolls over the top.
- Slice into squares and serve warm with maple syrup. Add a pinch of cinnamon or a little orange zest if you want a bakery vibe.
Recipe Variations
You can tailor this base to fit just about any table.
- Gluten-free: Use a sturdy gluten-free brioche or sandwich bread and check labels on cinnamon rolls if you use the shortcut.
- Vegan: Use plant milk, 2 cups Just Egg in place of eggs, coconut oil instead of butter, and a dairy-free cream cheese icing.
- Lower sugar or low carb: Use a low-carb bread, sweeten the custard with allulose or monk fruit, skip the streusel, and keep the drizzle light.
- Add-ins: Fold in 1.5 cups blueberries; or scatter 2 cups small apple chunks tossed with a teaspoon of cinnamon; or swirl in 1/2 cup pumpkin puree and a pinch of cloves.
Ways to Serve Cinnamon Roll French Toast Casserole
Brunch loves company, so set the table with a few easy sides.
- Fresh berries or a citrus salad to cut the richness
- Scrambled eggs and crispy bacon for a sweet-salty combo
- Greek yogurt and cinnamon for a creamy topper
- Strong coffee or a pitcher of orange juice
- Warm maple syrup and a dusting of powdered sugar
Storage
Cool leftovers, cover the dish, and refrigerate up to 4 days. Reheat slices in a 300 F oven for 10 to 15 minutes or in the microwave in short bursts. Freeze baked squares for up to 2 months; wrap tightly and thaw overnight in the fridge before reheating. Store icing separately and warm it gently before drizzling again.
