Ingredients You Need

Refrigerated cinnamon rolls, 2 standard cans with icing, 12 to 17.5 ounces each. I like Pillsbury Grands or Annie’s. Use the icing packets for the drizzle.
Large eggs, 6
Whole milk, 1.5 cups, or use half-and-half for a richer custard
Heavy cream, 1/2 cup, optional for extra richness
Pure vanilla extract, 2 teaspoons
Ground cinnamon, 2 teaspoons
Ground nutmeg, 1/4 teaspoon
Fine sea salt, 1/2 teaspoon
Light brown sugar, 1/2 cup, packed
Unsalted butter, 4 tablespoons, melted, plus a little to grease the pan
Maple syrup, 2 tablespoons, optional for deeper flavor
Chopped pecans or walnuts, 1/2 cup, optional for crunch
Optional extra icing if you skip the packets: cream cheese 4 ounces, powdered sugar 1 cup, vanilla 1/2 teaspoon, milk 1 to 2 tablespoons

Substitutions and notes:

Use gluten-free canned cinnamon rolls if you need a gluten-free option.
Swap in 8 cups cubed brioche or challah if you want a bread base. Add 2 tablespoons extra brown sugar and 1 teaspoon extra cinnamon to boost the swirl vibe.
Use coconut milk and dairy-free rolls to go dairy-free. Pick a dairy-free icing or make a simple powdered sugar glaze with non-dairy milk.

Equipment:

9×13 inch baking dish
Large mixing bowl and whisk
Knife or kitchen scissors for cutting dough
Measuring cups and spoons
Foil and nonstick spray or butter
Cooling rack, optional

Quick Tips & substitutions

Cut cinnamon rolls into quarters for chunky bites or into sixths for more custard coverage.
Grease the pan well. The syrupy goodness likes to stick.
Whisk the custard until smooth, then pour slowly so every piece soaks up flavor.
Chill at least 8 hours. The dough needs time to drink in the custard.
Bake covered for the first part of the cook to prevent over-browning. Uncover to finish and crisp the top.
Check doneness at the center. The custard should look set and jiggle slightly, not soupy.
No icing packets? Beat softened cream cheese with powdered sugar, vanilla, and milk until pourable.
No heavy cream? Use all milk and add 1 extra egg for structure.
Want less sweetness? Cut the brown sugar to 1/3 cup and skip the maple syrup.
Add-ins that work: pecans, raisins, mini chocolate chips, or diced apple.

How to Make Overnight Cinnamon Roll French Toast Casserole

Prep Time: 15 minutes
Cook Time: 40 to 45 minutes
Total Time: about 9 hours

Butter a 9×13 baking dish. Open the cinnamon roll cans and set the icing packets aside.
Cut each cinnamon roll into 4 to 6 pieces. Spread the pieces evenly in the baking dish.
Whisk eggs, milk, heavy cream, vanilla, cinnamon, nutmeg, salt, brown sugar, and melted butter in a large bowl until smooth. Stir in maple syrup if you use it.
Pour the custard evenly over the cinnamon roll pieces. Press lightly with a spatula so the tops touch the custard.
Cover the dish tightly with foil. Refrigerate for at least 8 hours or up to 24 hours.
Heat the oven to 350°F. Move the rack to the center.
Sprinkle pecans on top if you use them. Place the dish on a sheet pan to catch any bubbling syrup.
Bake, covered, for 25 minutes. Remove the foil and bake 15 to 20 minutes more, until the center looks set and the top turns golden.
Warm the icing packets in a bowl of hot water for 2 minutes. Drizzle the icing over the casserole.
Let the casserole rest for 10 minutes so the custard finishes setting. Slice and serve warm.

Simple Variations

Apple pie twist: Fold in 1.5 cups small diced apples and 1 teaspoon extra cinnamon.
Pecan sticky vibe: Add 1/4 cup extra brown sugar and 2 tablespoons melted butter over the top before baking, then shower with toasted pecans.
Orange roll: Add 1 tablespoon orange zest to the custard and finish with an orange juice glaze.
Mocha chip: Stir 1 tablespoon instant espresso powder into the custard and scatter 1/2 cup mini chocolate chips.
Maple bacon: Crumble 6 strips crisp bacon over the top after baking, then drizzle with warm maple syrup.

Ways to Serve Overnight Cinnamon Roll French Toast Casserole

Drizzle extra icing or a quick powdered sugar glaze.
Add whipped cream and fresh berries.
Serve with salty sides like bacon or breakfast sausage.
Pair with strong coffee, chai, or a citrusy mimosa.
Dust with powdered sugar for a bakery look.

Storage

Cool leftovers to room temp, then cover and refrigerate for up to 4 days. Reheat slices in a 300°F oven for 10 to 15 minutes, or microwave in 20 to 30 second bursts until warm. Freeze individual slices in airtight wraps for up to 2 months. Thaw overnight in the fridge and reheat until steamy.
