This cinnamon roll french toast casserole transforms weekend breakfast into a special occasion without the fuss. My family begs for this sweet, custard-soaked creation whenever we have overnight guests or holiday mornings, combining two breakfast favorites into one irresistible dish.
I first made this casserole when my sister and her kids were visiting during a snowy weekend. The house smelled amazing, and my nephew who normally skips breakfast had three helpings. Now it's our traditional Christmas morning breakfast while opening presents.
Ingredients
- Refrigerated cinnamon roll dough: Contains all the cinnamon sugar goodness without any mixing or rolling
- Eggs: Create the custardy french toast base that soaks into every crevice
- Whole milk and heavy cream: Provide richness that makes this casserole truly special
- Vanilla extract: Enhances the sweet flavors throughout the dish
- Ground cinnamon and nutmeg: Amplify the warm spice profile of the cinnamon rolls
- Maple syrup: Adds natural sweetness and caramelizes slightly during baking
- Chopped nuts: Add wonderful texture contrast to the soft custard
- The included icing: Creates that classic cinnamon roll finish
Step-by-Step Instructions
- Prepare Your Baking Dish:
- Generously grease a 9x13 inch baking dish with butter or cooking spray, ensuring no spot is missed. This prevents sticking and makes serving much easier. I like to use a glass dish so I can see how the bottom is browning.
- Cut The Cinnamon Rolls:
- Open both cans of cinnamon rolls and set aside the icing packets for later. Cut each roll into quarters using a sharp knife. The pieces don't need to be perfectly even. Arrange them evenly across your prepared baking dish, slightly overlapping some pieces for texture variation.
- Create The Custard Mixture:
- In a large bowl, crack all six eggs and whisk until the yolks and whites are fully incorporated. Pour in the milk, heavy cream, vanilla extract, then sprinkle in the cinnamon and nutmeg. Whisk vigorously until the mixture is smooth with no streaks of egg visible. The custard should be a light tan color from the spices.
- Combine Everything:
- Pour the egg mixture slowly and evenly over the cinnamon roll pieces, making sure to cover all areas. Use a spatula or the back of a spoon to gently press down on the pieces so they absorb the custard. If using nuts or maple syrup, distribute them evenly over the top now.
- Bake To Perfection:
- Cover the dish with foil, being careful not to press it down onto the casserole. Bake covered for exactly 25 minutes, which allows the custard to begin setting without over-browning the top. Remove the foil and continue baking for 15-20 minutes more until the center is set but still slightly jiggly and the top pieces are golden brown.
- Add The Finishing Touch:
- Microwave the reserved icing packets for just 5-10 seconds to make them easier to drizzle. While the casserole is still warm but not piping hot, drizzle the icing in a zigzag pattern across the top. The residual heat will help the icing melt slightly into the crevices.

My favorite part about this recipe is watching guests try to figure out what makes it so delicious. The secret is using those refrigerated cinnamon rolls instead of bread. My daughter always requests this for her birthday breakfast, and watching her face light up when she smells it baking is worth every calorie.
Make Ahead Options
This casserole shines as a make-ahead breakfast solution. You can prepare everything up to the baking stage, cover tightly with plastic wrap, and refrigerate overnight. In the morning, remove from the refrigerator while preheating the oven, and add about 5-10 minutes to the covered baking time since you're starting with cold ingredients. This makes holiday mornings so much more relaxed, allowing you to enjoy coffee with your family instead of rushing around the kitchen.
Storage And Reheating
Leftovers store beautifully in the refrigerator for up to 3 days. Cover the baking dish with plastic wrap or transfer portions to airtight containers. To reheat, microwave individual servings for 30-45 seconds until just warmed through. For a crispier top, place refrigerated portions in a 300°F oven for about 10 minutes. I actually think the flavors develop even more on the second day, making the leftovers sometimes better than the original serving.
Delicious Variations
Transform this basic recipe with simple additions that create whole new flavor profiles. For a fall version, add diced apples tossed in cinnamon and a sprinkle of caramel bits before baking. In summer, fresh berries added to the top halfway through baking add beautiful color and tartness. For chocolate lovers, sprinkle mini chocolate chips between the cinnamon roll pieces. My personal favorite variation includes a layer of cream cheese mixture made by beating 8 ounces of softened cream cheese with 1/4 cup sugar and spreading it over the cinnamon roll pieces before adding the custard.

This cinnamon roll casserole will quickly become a family tradition, bringing joy and warmth to your mornings with minimal effort.
Frequently Asked Questions
- → Can I prepare this casserole the night before?
Yes! You can assemble the entire casserole, cover it tightly with plastic wrap, and refrigerate overnight. In the morning, remove it from the refrigerator 30 minutes before baking to take the chill off, then bake as directed. This makes it perfect for holiday mornings.

If you don't have heavy cream, you can use half-and-half or additional milk. The casserole won't be quite as rich but will still taste delicious. For a dairy-free version, substitute almond or coconut milk.

This casserole pairs wonderfully with fresh fruit, bacon or sausage, and extra maple syrup. For a complete brunch, add a light salad and mimosas or coffee.
