Ingredients You’ll Need

1 package (12 rolls total) King’s Hawaiian sweet rolls: These soft, slightly sweet rolls provide the perfect base for your casserole—nothing else compares to their delightful texture.
6 large eggs: Eggs bind everything together while adding richness and flavor. Use room temperature eggs for the best custard consistency.
1 ¼ cups whole milk: Whole milk adds a creamy backbone to the custard. If you’re looking for a lighter version, you can substitute with almond milk.
¼ cup heavy cream: To enhance the richness and creaminess, don’t skip this ingredient!
¼ cup granulated sugar: This sweetens the custard just enough while creating that beautiful caramelization on top.
1 tablespoon vanilla extract: The aroma of vanilla enhances the entire dish, making it comforting and inviting.
1 ¼ teaspoon ground cinnamon: This warming spice infuses delightful flavor throughout.
¼ teaspoon salt: A key ingredient to balance the sweetness and elevate all flavors.
2 tablespoon unsalted butter, melted: Butter not only enhances flavor but also helps achieve a golden crust.
Confectioners’ sugar and maple syrup: These are optional but give a sweet finishing touch when serving.
⅓ cup all-purpose flour: This is used for the streusel topping, adding a delicious crunch.
⅓ cup packed light brown sugar: Brown sugar adds moisture and a hint of caramel flavor to the streusel.
½ teaspoon ground cinnamon: Just a touch for an extra layer of warm spice in the topping.
¼ teaspoon salt: Balancing the sweetness in the streusel topping.
4 tablespoon unsalted butter, chilled and cut into cubes: Cut into the flour mixture for that crumbly texture that makes streusel so irresistible.

How to Make Hawaiian Roll French Toast Casserole

Preheat and Prepare the Baking Dish: Preheat your oven to 350 degrees F and lightly grease a 9×13-inch baking dish with butter. Arrange the bottoms of the Hawaiian rolls snugly in a single layer, cut side up.
Make the Custard: In a large mixing bowl, whisk together 6 large eggs, 1 ¼ cups whole milk, ¼ cup heavy cream, ¼ cup granulated sugar, 1 tablespoon vanilla extract, 1 ¼ teaspoon ground cinnamon, and ¼ teaspoon salt. Ensure everything is fully combined.
Soak the Rolls: Pour half of the custard mixture evenly over the rolls, gently pressing to saturate each piece.
Reassemble the Rolls: Dip each top half of the rolls into the remaining custard, coating them well before placing them back on their matching bottoms.
Fill in Gaps: Pour any remaining custard mixture into the gaps between the nested rolls. Drizzle 2 tablespoons of melted butter over the tops for excellent browning.
Prepare the Streusel: In a small bowl, combine ⅓ cup all-purpose flour, ⅓ cup packed light brown sugar, ½ teaspoon ground cinnamon, and ¼ teaspoon salt. Using a pastry blender, fork, or your fingers, cut in 4 tablespoons of cold, cubed butter until you achieve a coarse crumb texture.
Add the Streusel: Evenly sprinkle the streusel over the top of the casserole.
Bake: Tent the baking dish with foil and bake for 30 minutes. Remove the foil and continue baking for another 20-25 minutes until the top is golden and the center is set—check doneness with a knife; it should come out mostly clean.
Rest and Serve: Allow the casserole to rest for about 5-10 minutes. Dust the top with confectioners’ sugar for an elegant touch and serve it warm with maple syrup if desired.

Storing & Reheating

To store any leftovers, keep them in an airtight container in the refrigerator for up to 3 days. For longer storage, freeze the casserole wrapped tightly in plastic wrap and aluminum foil for up to 3 months. When you’re ready to enjoy, reheat individual portions in the microwave or warm the entire dish in a preheated oven at 350 degrees F until heated through. Be mindful that freezing and reheating may slightly alter the texture, so a drizzle of maple syrup can help refresh the flavors.

Chef’s Helpful Tips

For a creamier custard, use fresh heavy cream and whole milk—avoid half-and-half, as it can make the texture heavy.
If the mixture seems dry before baking, drizzle a bit more custard on top; the rolls should be well-soaked.
Letting the casserole rest after baking allows it to firm up, making it easier to slice and serve.
You can mix in fruits like blueberries or sliced strawberries for added flavor and freshness.

This Hawaiian Roll French Toast Casserole is truly an effortless way to enjoy a decadent breakfast. Its combination of sweet flavors and fluffy textures is sure to please anyone at the table. Try to share it—though it may be tough to resist seconds! Experimenting with additional ingredients or toppings could lead to your own unique twist—so have fun with this recipe.

Recipe FAQs

Can I make this recipe ahead of time?

Absolutely! You can prepare the casserole the night before, just cover it tightly and refrigerate. In the morning, bake it straight from the fridge; you may need to add an extra 10-15 minutes to the baking time.

What can I substitute for the Hawaiian rolls?

If you can’t find Hawaiian rolls, other sweet bread options like brioche or challah work beautifully! The key is to use a bread that can soak up the custard well.

How do I know when the casserole is done?

The casserole is done when the top is golden brown, and a knife inserted into the center comes out mostly clean. If you see wet custard, add a few more minutes to baking time.

Can I freeze leftovers?

Yes! Freeze leftovers wrapped tightly in plastic wrap and foil for up to 3 months. Just remember to reheat cautiously so the texture remains pleasant!
