Years ago, I stumbled upon this casserole recipe during a rainy weekend when I wanted something comforting but less fussy than rolling out dough.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and substitutions are easy if needed.

• Store-bought cinnamon rolls (1 package, about 8 rolls) – I recommend using classic refrigerated cinnamon rolls with icing included for convenience and flavor.
• Eggs (6 large, room temperature) – the backbone of the custard that soaks the bread.
• Whole milk (2 cups / 480 ml) – for richness; you can swap with almond or oat milk for dairy-free.
• Heavy cream (1 cup / 240 ml) – adds extra creaminess but can be replaced with more milk if preferred.
• Vanilla extract (2 teaspoons) – brings out the sweet, warm flavors.
• Ground cinnamon (1 teaspoon) – enhances the cinnamon roll flavor.
• Brown sugar (2 tablespoons) – adds a caramel note to the custard.
• Salt (a pinch) – balances the sweetness.
• Icing from the cinnamon roll package (optional, for drizzling) – or homemade glaze if you want to get fancy.

If you want to get creative, you can swap out the cinnamon rolls for gluten-free versions or vegan cinnamon rolls. For a seasonal twist, add fresh berries or chopped nuts before baking. The beauty here is in the simplicity and flexibility.

Equipment Needed

• 9×13-inch baking dish: A standard size that fits the casserole perfectly.
• Mixing bowl: For whisking the custard ingredients.
• Whisk or fork: To blend the eggs and liquids thoroughly.
• Knife: To cut the cinnamon rolls into pieces.
• Measuring cups and spoons: For precise ingredient amounts.
• Aluminum foil or plastic wrap: To cover the casserole while it soaks overnight.

If you don’t have a 9×13 dish, a similar-sized oven-safe casserole dish will work fine. For whisking, a fork can do the job if you don’t own a whisk. I personally find silicone spatulas handy for scraping every bit of custard out of the bowl.

Preparation Method

1. Prepare the cinnamon rolls: Open your package of cinnamon rolls and cut each roll into quarters (about 32 pieces). This helps them absorb the custard evenly. Place the pieces in an even layer in your greased 9×13-inch baking dish. (Tip: Greasing the dish prevents sticking and makes cleanup easier.)
2. Make the custard: In a large mixing bowl, whisk together 6 large eggs, 2 cups (480 ml) whole milk, 1 cup (240 ml) heavy cream, 2 teaspoons vanilla extract, 1 teaspoon ground cinnamon, 2 tablespoons brown sugar, and a pinch of salt. Whisk until fully combined and slightly frothy. (This custard is the magic that soaks the cinnamon roll pieces, making them tender and flavorful.)
3. Pour custard over cinnamon rolls: Slowly pour the custard mixture evenly over the cinnamon roll pieces, making sure all pieces get good coverage. Gently press down on the pieces with a spatula to help them soak up the liquid. (If you want extra gooeyness, let it sit for a few minutes before covering.)
4. Cover and refrigerate overnight: Cover the dish tightly with aluminum foil or plastic wrap and place it in the fridge for at least 6 hours or overnight. This step is key for the custard to soak in fully, creating that melt-in-your-mouth texture.
5. Preheat the oven: The next morning, preheat your oven to 350°F (175°C). Remove the casserole from the fridge while the oven heats.
6. Bake the casserole: Bake uncovered for 45-50 minutes, or until the top is golden brown and the custard is set (a knife inserted in the center should come out clean, with no runny custard). (If the top browns too fast, tent lightly with foil.)
7. Add the icing: Once out of the oven, drizzle the cinnamon roll icing over the warm casserole. If you like, warm the icing slightly for easier drizzling. Let the casserole cool for 5-10 minutes before serving.

Pro tip: If you want crispy edges, bake a little longer or broil for 1-2 minutes at the end, but watch carefully to avoid burning. Also, using room temperature eggs and milk helps the custard blend smoothly.

Cooking Tips & Techniques

Honestly, this Easy Overnight Cinnamon Roll French Toast Casserole is pretty forgiving, but I’ve learned a few things from making it time and again:

• Don’t skip the overnight soak: Letting the custard soak in gives the cinnamon rolls time to absorb all that creamy goodness. Without it, you’ll get dry edges and uneven texture.
• Use fresh eggs and good-quality milk: It really makes a difference in flavor and texture. I prefer whole milk and heavy cream for richness, but lighter milks work too.
• Cut cinnamon rolls into uniform pieces: This ensures even soaking and baking. I’ve made the mistake of leaving some chunks too big and they stayed doughy.
• Press down gently after pouring custard: Helps the pieces nestle in and prevents floating.
• Cover tightly in the fridge: To avoid any fridge smells sneaking in.
• Watch the baking time: Every oven is different. Start checking at 45 minutes to avoid drying out.
• Let it rest before serving: The casserole firms up a bit and is easier to cut.

Multitasking tip: While it bakes, you can get your coffee ready or prepare some fresh fruit to complement the casserole. That way, breakfast is ready at the same time everything else is set.

Variations & Adaptations

This recipe is a great base to play with, so feel free to customize it:

• Dietary: Use gluten-free cinnamon rolls or swap milk and cream for dairy-free options like almond or oat milk and coconut cream.
• Flavor twists: Add a handful of chopped pecans or walnuts for crunch, or sprinkle mini chocolate chips over the top before baking for extra indulgence.
• Seasonal: Toss in fresh or frozen berries like blueberries or raspberries for a fruity surprise.
• Cooking method: Try baking it in smaller ramekins for individual servings or even slow cook on low for 3-4 hours (great for busy mornings).
• Personal favorite: I once swirled in some pumpkin puree and pumpkin pie spice during fall—it was a hit with my family and added a cozy seasonal vibe.

Serving & Storage Suggestions

This casserole is best served warm, fresh out of the oven, drizzled with that sweet cinnamon roll icing. I like to pair it with fresh fruit, a dollop of yogurt, or even a glass of cold milk or hot coffee to balance the sweetness.

Leftovers? No worries! Store them covered in the refrigerator for up to 3 days. For longer storage, freeze portions wrapped tightly in foil or plastic wrap for up to 2 months. To reheat, pop a slice in the microwave for 30-60 seconds or in a toaster oven until warmed through and slightly crispy on the edges.

Flavors develop beautifully after resting, so if you make it the night before and serve the next morning, you’re in for a treat. Just remember to drizzle the icing right before serving so it stays fresh and glossy.

Nutritional Information & Benefits

This Easy Overnight Cinnamon Roll French Toast Casserole is a decadent treat, but it also brings some nutritional perks. Eggs provide quality protein and essential vitamins, while cinnamon adds antioxidants and a warm, comforting flavor without extra calories.

Using whole milk and cream makes it rich and satisfying, but you can lighten it up by using low-fat milk or plant-based alternatives. Keep in mind, this recipe contains gluten, dairy, and eggs, so it’s not suitable for those with allergies to these ingredients (though substitutions are possible).

From a wellness perspective, this dish is perfect as an occasional indulgence that feels like a special breakfast without hours of prep—making it easier to enjoy with loved ones and savor the moment.
