Ingredients

For the Casserole:

• 1 loaf (16 oz/450g) day-old brioche or challah bread, cut into 1-inch cubes
• 8 large eggs
• 2 cups (480ml) whole milk
• ½ cup (120ml) heavy cream
• ¾ cup (150g) granulated sugar
• 2 tablespoons vanilla extract
• 1 tablespoon ground cinnamon
• ¼ teaspoon salt

For the Cinnamon Swirl:

• ¾ cup (150g) brown sugar, packed
• ¼ cup (55g) unsalted butter, melted
• 2 tablespoons ground cinnamon

For the Cream Cheese Glaze:

• 4 oz (115g) cream cheese, softened
• 1 cup (120g) powdered sugar
• 3 tablespoons milk
• ½ teaspoon vanilla extract

The bread selection is crucial for your Cinnamon Roll French Toast Casserole—brioche or challah provide the perfect rich base that absorbs the custard while maintaining structure. Using day-old bread ensures it won’t become too soggy during baking. The cinnamon-sugar mixture creates those signature swirls reminiscent of classic cinnamon rolls, while the cream cheese glaze delivers that final authentic touch that makes this dish truly exceptional.

Pro Tips

Getting your Cinnamon Roll French Toast Casserole just right comes down to a few critical techniques that elevate it from good to spectacular.

First, the bread selection and preparation make all the difference. For the best texture, use bread that’s slightly stale or dry it out yourself by cutting it into cubes and leaving them out for a few hours before assembly. This ensures the bread absorbs the custard without collapsing into mush. If you’re short on time, spreading the cubes on a baking sheet and placing them in a 200°F oven for 10 minutes will achieve the same effect.

Second, master the layering technique for maximum cinnamon impact. Instead of mixing all ingredients together, create distinct layers: place half the bread cubes in your baking dish, drizzle with half the cinnamon mixture, add remaining bread, then top with the rest of the cinnamon mixture. This creates pockets of cinnamon sugar throughout the casserole rather than just on top.

Finally, the resting period is non-negotiable. Allow at least 30 minutes (or ideally overnight in the refrigerator) for the custard to fully penetrate the bread. This not only improves the texture but also deepens the flavor as the cinnamon and vanilla infuse throughout. When baking after refrigeration, let the casserole sit at room temperature for 30 minutes before placing it in the oven to ensure even cooking.

Instructions

Step 1: Prepare the Baking Dish
Generously butter a 9×13 inch baking dish, making sure to get into all corners and up the sides. This prevents sticking and helps create those desirable crispy edges that everyone fights over. If you’re planning to refrigerate overnight, use a ceramic or glass dish that can handle temperature changes without cracking.

Step 2: Prepare the Bread
Cut your brioche or challah bread into 1-inch cubes. If your bread isn’t already day-old, spread the cubes on a baking sheet and dry them in a 200°F oven for about 10 minutes. The bread should be dry but not toasted. Transfer half of the bread cubes to your prepared baking dish.

Step 3: Create the Cinnamon Swirl Mixture
In a medium bowl, whisk together the brown sugar, melted butter, and cinnamon until well combined. The mixture should resemble wet sand and smell wonderfully aromatic. Drizzle half of this mixture over the bread cubes already in the baking dish, using a spoon to distribute it evenly.

Step 4: Add Remaining Bread and Cinnamon
Add the remaining bread cubes to the baking dish, creating an even layer. Drizzle the rest of the cinnamon swirl mixture on top, again distributing it evenly to ensure every serving gets that delicious cinnamon flavor.

Step 5: Prepare the Custard
In a large bowl, whisk together eggs, milk, cream, granulated sugar, vanilla extract, cinnamon, and salt until completely smooth. Take your time with this step to ensure the eggs are fully incorporated and the mixture is homogeneous.

Step 6: Combine and Rest
Pour the custard mixture evenly over the bread cubes, pressing down gently with a spatula to help the bread absorb the liquid. Cover with plastic wrap and refrigerate for at least 30 minutes or overnight (up to 12 hours) for best results.

Step 7: Bake to Perfection
When ready to bake, preheat your oven to 350°F (175°C). If the casserole has been refrigerated overnight, let it sit at room temperature for 30 minutes. Bake for 45-55 minutes until puffed, golden brown, and set in the center. A knife inserted in the middle should come out clean.

Step 8: Prepare the Cream Cheese Glaze
While the casserole is baking, beat the softened cream cheese until smooth. Add powdered sugar gradually, then whisk in milk and vanilla until you achieve a pourable consistency. If the glaze seems too thick, add more milk a teaspoon at a time.

Step 9: Serve Warm
Allow the Cinnamon Roll French Toast Casserole to cool for 10-15 minutes before drizzling with the cream cheese glaze. This cooling period allows the casserole to set while still serving it warm. Cut into squares and serve with additional warm maple syrup if desired.

Variations

The beauty of this Cinnamon Roll French Toast Casserole lies in its versatility. Here are some delicious variations to keep this recipe exciting every time you make it:

Apple Cinnamon Roll Casserole: Add 2 cups of peeled, diced apples tossed in cinnamon and a tablespoon of lemon juice between the layers of bread. The apples will become tender during baking, creating a lovely apple pie-inspired breakfast casserole. This variation works beautifully in fall when apples are in season.

Pumpkin Spice Version: For an autumn twist, add ½ cup of pumpkin puree and 1 teaspoon of pumpkin pie spice to the custard mixture. This creates a seasonal breakfast casserole that’s perfect for Thanksgiving morning or any cool fall weekend. Top with toasted pecans before baking for extra crunch.

Gluten-Free Adaptation: This recipe adapts well to dietary restrictions. Simply substitute your favorite gluten-free bread (ideally one with a rich, soft texture similar to brioche). Ensure the bread is slightly dry before assembling, as some gluten-free breads can be more prone to becoming soggy. The rest of the recipe remains unchanged, allowing everyone to enjoy this breakfast treat regardless of gluten sensitivities.

Storage and Serving

Your Cinnamon Roll French Toast Casserole can be enjoyed beyond the initial serving with proper storage. Refrigerate leftovers in an airtight container for up to 3 days. For best results when reheating, cover individual portions with a damp paper towel and microwave for 30-45 seconds, or reheat larger portions covered with foil in a 325°F oven until warmed through (about 15-20 minutes).

For make-ahead convenience, you can also freeze the baked casserole for up to 2 months. Cut into individual portions before freezing for easier reheating. Thaw overnight in the refrigerator before reheating as described above.

When it comes to serving, this casserole shines as the centerpiece of a brunch spread. Pair it with savory counterpoints like a crisp bacon platter or a fresh fruit salad to balance the sweetness. For an elegant presentation, dust with powdered sugar just before serving and add fresh berries around the platter.

For an indulgent dessert-for-breakfast experience, serve warm with a scoop of vanilla ice cream or freshly whipped cream. Alternatively, offer maple syrup, caramel sauce, or additional cream cheese glaze on the side, allowing guests to customize their serving to their desired level of sweetness.

Frequently Asked Questions

Can I make this casserole without refrigerating overnight?
Yes, while an overnight rest produces the best texture, you can make this Cinnamon Roll French Toast Casserole the same day. Allow it to rest at room temperature for at least 30-45 minutes before baking to give the bread time to absorb the custard.

What’s the best bread to use if I can’t find brioche or challah?
French bread or a good-quality white sandwich bread will work well as alternatives. The key is using bread with some density that can stand up to soaking without falling apart. Avoid very airy or crusty artisan breads.

Why is my casserole soggy in the middle?
This usually happens if the bread is too fresh or if the casserole hasn’t baked long enough. Ensure your bread is slightly dry before assembly and check that your oven temperature is accurate. If the top is browning too quickly but the center isn’t set, cover loosely with foil and continue baking.

Can I make this dairy-free?
Absolutely! Substitute plant-based milk, vegan butter, and dairy-free cream cheese for their conventional counterparts. Coconut cream works well in place of heavy cream, adding a subtle complementary flavor to the cinnamon.

How do I know when the casserole is done baking?
The casserole is done when it’s puffed up, golden brown on top, and a knife inserted in the center comes out clean without liquid custard. The internal temperature should reach 160°F if you’re using a thermometer.

Conclusion

This Cinnamon Roll French Toast Casserole is comfort food at its finest — a magnificent marriage of two breakfast favorites transformed into something greater than the sum of its parts. It’s the kind of dish that creates memories, whether served on Christmas morning, at a celebratory brunch, or simply as a weekend treat that makes ordinary days feel special.
