I’ve made this Cinnamon Roll French Toast Casserole more times than I can count, and every time, it’s a guaranteed crowd-pleaser. Whether it’s a lazy weekend brunch or a holiday breakfast, this dish delivers warm, gooey comfort in every bite. It combines everything I love about classic cinnamon rolls with the rich, custardy texture of traditional French toast.

The beauty of this casserole is how effortless it is to prepare. I often assemble it the night before, letting all the cinnamon-sugar goodness soak in, and just pop it in the oven in the morning.

Why You’ll Love This Cinnamon Roll French Toast Casserole

This casserole is equal parts cozy and convenient. It’s made with pre-made cinnamon rolls (yes, the ones from the can!), so you skip the time-consuming dough prep without sacrificing flavor. The result is a pull-apart style breakfast that’s soft in the center, crispy on the edges, and loaded with cinnamon swirls in every bite. Plus, it feeds a crowd and can be prepped ahead—perfect for holidays, brunch parties, or special family mornings.

What Kind of Cinnamon Rolls Should I Use?

You can use any canned cinnamon rolls for this recipe, and both classic and jumbo-sized versions work well. I typically go for the Pillsbury Grands because they bake up extra fluffy and come with a generous icing packet. If you’re feeling adventurous, homemade cinnamon rolls are a luxurious option, but not necessary—this dish shines even with the store-bought stuff.

Options for Substitutions

No cinnamon rolls on hand? Try using day-old brioche or challah bread tossed with a cinnamon-sugar mixture and a bit of melted butter. For a dairy-free version, substitute almond or oat milk and use coconut cream in place of the icing. You can also add extras like chopped pecans, raisins, or a swirl of cream cheese throughout the casserole for an added touch of richness and texture.

Ingredients for this Cinnamon Roll French Toast Casserole

Refrigerated Cinnamon Rolls – The heart of the dish. These provide the sweet, doughy base and bring that signature cinnamon swirl in every bite. You’ll also use the included icing for topping.

Eggs – Essential for creating the custard base. They bind everything together and help the casserole bake into a creamy, soft texture.

Whole Milk – Adds richness and helps soak the cinnamon rolls. You can substitute with half-and-half or a dairy-free alternative if needed.

Heavy Cream – Boosts the creaminess of the custard and gives it a luxurious texture.

Vanilla Extract – Enhances the sweetness and brings warmth to the flavor profile.

Cinnamon – Intensifies the cinnamon flavor already present in the rolls. A must for that cozy, spiced aroma.

Nutmeg (optional) – Adds depth and complexity. A little goes a long way.

Maple Syrup or Brown Sugar – Optional but recommended for added sweetness and caramelized edges.

Butter (for greasing) – Prevents sticking and adds a buttery richness to the bottom crust.

Whipped Cream or Cream Cheese Glaze – For topping. It’s the finishing touch that takes this casserole over the top.

Step 1: Prep the Baking Dish

Grease a 9×13-inch baking dish generously with butter or non-stick spray. This helps ensure the casserole lifts out easily and doesn’t stick to the pan.

Step 2: Cut the Cinnamon Rolls

Open the cans of cinnamon rolls and set aside the icing packets. Cut each roll into 4–6 small pieces and place them evenly in the greased dish.

Step 3: Make the Custard Mixture

In a large mixing bowl, whisk together the eggs, milk, heavy cream, vanilla extract, cinnamon, and a pinch of nutmeg if using. Make sure the mixture is smooth and well combined.

Step 4: Pour Custard Over Rolls

Pour the egg mixture evenly over the cut cinnamon roll pieces in the baking dish. Press the pieces down gently with a spatula so they soak up the custard.

Step 5: Chill (Optional but Recommended)

For best results, cover the dish with foil and refrigerate for at least 30 minutes or overnight. This allows the cinnamon rolls to absorb the custard fully.

Step 6: Bake the Casserole

Preheat your oven to 350°F (175°C). Bake the casserole for 35–40 minutes uncovered, or until the top is golden brown and the center is set but still slightly soft.

Step 7: Add the Icing and Toppings

Once baked, remove the casserole from the oven and let it rest for 5–10 minutes. Warm the icing packets in your hands or microwave for a few seconds, then drizzle over the casserole. Top with whipped cream or cream cheese glaze if desired.

Step 8: Serve Warm

Slice into squares and serve warm with a cup of coffee, tea, or a glass of milk. Every bite is sweet, soft, and irresistibly cinnamony.

How Long to Prepare the Cinnamon Roll French Toast Casserole

Preparation Time: If you’re making it fresh in the morning, the prep takes around 15–20 minutes. That includes cutting the cinnamon rolls, whisking the custard mixture, and assembling everything in the dish. If you’re short on time, you can skip the chilling step, though it does enhance texture.

Bake Time: The casserole bakes for about 35–40 minutes. You’ll know it’s done when the top is golden brown and the center is set but slightly soft. For a firmer texture, bake closer to 45 minutes.

Tips for Perfect Cinnamon Roll French Toast Casserole

Use day-old cinnamon rolls (if homemade): Slightly stale rolls soak up custard better without becoming soggy.
Let it soak overnight: For the best texture, allow the casserole to chill overnight. It gives the egg mixture time to fully penetrate the rolls.
Cover with foil if browning too fast: If the top is browning before the center is cooked, tent it loosely with foil halfway through baking.
Warm the icing: Microwave the icing for 5–10 seconds to make it pourable and easier to drizzle.
Serve immediately: This casserole is best served warm and fresh out of the oven.

Watch Out for These Mistakes While Cooking

Not greasing the pan properly: This leads to sticking and messy slices.
Overbaking: It can make the casserole dry and chewy. Keep an eye on the texture.
Under-whisking the custard: A lumpy mixture can lead to uneven baking.
Skipping the chill time: While optional, this step improves consistency and flavor absorption.
Pouring icing on too soon: Let it rest a few minutes first or the icing will melt too much and disappear.
