Gather Your Ingredients and Tools

Gathering everything you need before starting makes the preparation process for hawaiian roll french toast casserole much smoother. Let me walk you through all the essential ingredients and tools you’ll need.

Hawaiian rolls and why they work best

First, you’ll need a 12-ounce package of King’s Hawaiian Sweet Rolls. These rolls are the star of this recipe for good reason. Unlike regular french bread, Hawaiian rolls already have a built-in sweetness and pillowy texture that creates the perfect foundation for french toast casserole. Furthermore, their slightly dense structure allows them to soak up the custard without falling apart. If you happen to have day-old or slightly stale Hawaiian rolls, even better—they’ll absorb more of the delicious custard mixture.

Eggs, milk, and cream: the custard base

For the custard base, you’ll need:

6-8 large eggs
1½-2 cups of milk[61]
¼ cup heavy cream

The combination of milk and cream creates the perfect custard consistency—rich without being overly heavy. For dairy alternatives, feel free to substitute almond milk, coconut milk, or soy milk. Additionally, if you don’t have heavy cream, you can use a mixture of whole milk plus heavy whipping cream (1 cup whole milk + ⅓ cup heavy cream works well).

Optional add-ins: berries, chocolate, or nuts

To elevate your hawaiian roll french toast bake, consider these delicious add-ins:

Fresh berries (blueberries, raspberries, blackberries, or strawberries)
Dark chocolate chips (½ cup)
Chopped nuts like pecans or walnuts for crunch[61]

These add-ins can be layered between the bread pieces or sprinkled on top before baking for extra flavor and texture contrast.

Recommended baking dish sizes

The right baking dish ensures even cooking. For this easy hawaiian roll french toast casserole, I recommend using either:

An 11×7 inch dish
A 12×8 inch baking dish

A standard 9×13 inch dish can work too, though keep in mind that different dish sizes may affect baking time. Regardless of which size you choose, remember to grease your baking dish with non-stick spray or butter before adding your ingredients.

How to Assemble the Casserole

The assembly process for hawaiian roll french toast casserole is surprisingly simple yet crucial for achieving that perfect texture balance. Let me guide you through each step to ensure your breakfast masterpiece turns out perfectly every time.

Cutting or tearing the rolls

Start the assembly process by preparing your Hawaiian rolls. You have two options here: cutting or tearing. For a more uniform appearance, use a serrated knife to slice the rolls into approximately 1-inch cubes. This method creates even pieces that will cook consistently. Alternatively, simply tear the rolls into bite-sized chunks for a more rustic presentation. Either technique works well, yet I prefer cutting with a serrated knife since it allows for more precise, evenly-sized pieces that absorb the custard uniformly.

Layering bread and add-ins

Once your rolls are prepared, arrange them evenly in your greased baking dish. For a more complex flavor profile, consider creating layers. First, place half of your bread pieces in the dish, then add a layer of fresh berries or other add-ins, followed by the remaining bread and another layer of add-ins on top. This layering technique ensures every bite contains a perfect balance of fluffy bread and flavorful additions.

Mixing and pouring the custard evenly

Next, prepare your custard mixture in a large bowl. Vigorously whisk together eggs, milk, cream, sugar, vanilla, and cinnamon until completely combined with no visible egg streaks. For the best results, pour the custard slowly and evenly over the bread pieces, making sure to coat every piece. Should you miss any areas, gently press the dry pieces down into the liquid using a spoon. However, avoid pressing too firmly as you don’t want to squish the bread completely.

After pouring, some recipes recommend allowing the casserole to rest for about 5-15 minutes before baking, although for a fuller flavor experience, you could refrigerate it for up to 12 hours.

Baking for the Perfect Texture

The magic of hawaiian roll french toast casserole happens in the oven where proper baking techniques transform a simple assembly into a delectable breakfast masterpiece with the perfect texture balance.

Covering vs. uncovering during bake

Baking your hawaiian roll french toast casserole uncovered typically yields the best results. This approach allows the top to become golden brown, crispy, and caramelized – which many consider the most delightful part of the casserole. For a streusel-topped version, the uncovered method is especially important as it creates that crunchy, caramelized texture everyone loves.

Nevertheless, if you notice your hawaiian roll french toast bake browning too quickly, simply lay a piece of foil loosely on top during the latter part of baking. Some recipes recommend starting covered, then uncovering: “Cover and bake for 35 minutes at 350°F, then uncover and bake for another 10 to 20 minutes”. This dual approach provides the best of both worlds – a moist interior with a crisp exterior.

How to know when it’s done

Your french toast casserole with hawaiian rolls is done when:

The top is golden brown and edges appear crispy
The center is completely set and doesn’t jiggle when gently shaken
A toothpick inserted into the center comes out clean

For those who prefer precise measurements, custards typically reach doneness at an internal temperature of 175°F. Once baked, let your casserole stand for 5-10 minutes before serving. During this time, the bread will initially puff in the oven and then slightly sink as it cools.

Tips to avoid soggy or dry casserole

A common issue with easy hawaiian roll french toast casserole is excessive sogginess. To prevent this:

Firstly, ensure you’re not using too much custard mixture. The main culprit of a soggy casserole is often excess liquid that cannot be absorbed. If you find your mixture too wet, consider using a baking dish with more surface area to promote better evaporation.

Consequently, the type of bread matters significantly. The hawaiian rolls should ideally be slightly dried out before using. Fresh bread often doesn’t absorb enough custard, resulting in sogginess. Moreover, if your casserole still turns out soggy, bake it longer – increasing the baking time helps set the custard and remove excess moisture.

Finally, for a drier result, consider mixing the bread and custard in a separate bowl first, draining any excess liquid before transferring to your baking dish.

Toppings, Variations, and Make-Ahead Tips

Taking your hawaiian roll french toast casserole from good to extraordinary happens after baking, with the right toppings and variations. Plus, knowing how to prep ahead makes this dish even more convenient for busy mornings.

Streusel topping or powdered sugar

The cinnamon streusel topping truly elevates this dish with its buttery, crumbly texture. Mix flour, brown sugar, cinnamon, salt, and melted butter until combined for a caramelized layer that many consider sweet enough to skip syrup altogether. For a simpler finish, dust with powdered sugar just before serving. Indeed, many find the streusel so deliciously sweet that maple syrup becomes optional rather than essential.

Fruit swaps and dessert versions

Beyond blueberries, try these delicious fruit variations:

Strawberries, blackberries, or mixed berry medleys
Fresh peaches during summer months
Sliced apples for a fall-inspired version

For dessert-worthy versions, consider adding Nutella, chocolate chips, caramel sauce, or even transform leftovers into dessert by topping with vanilla ice cream.

Overnight prep and storage tips

Prepare this casserole up to 12 hours ahead of time. Simply assemble everything, cover tightly, and refrigerate overnight—a lifesaver for holiday mornings. For longer storage, you can freeze the baked casserole for up to 2-3 months.

Reheating leftovers the right way

Refrigerated leftovers stay fresh for 3-4 days. When reheating, the oven method works best—cover with foil and heat at 350°F for 20-30 minutes. For individual portions, microwave for 1-2 minutes on medium power. To maintain moisture during reheating, sprinkle 1-2 tablespoons of milk over the top beforehand.
