Can I make Hawaiian roll casserole ahead of time?

Yes, absolutely. Prep it the night before, cover, and refrigerate. It’s ready to pop in the oven in the morning with minimal extra effort.

What’s the best size pan for this recipe?

An 11×7 or 12×8 inch baking dish works perfectly. A deeper oval dish also performs well but may require a bit more bake time.

Can I skip the berries or use another fruit?

Yes. Berries are optional. You can use bananas, apples, or skip fruit altogether. Chocolate chips and nuts are great alternatives.

How do I know when it’s fully baked?

The top should be golden brown and the center just slightly jiggly. A knife inserted in the middle should come out mostly clean.

Can I use other types of bread?

Yes, though King’s Hawaiian rolls are recommended for their sweetness and soft texture. Brioche or challah are solid alternatives.

Instructions

Preheat oven to 350°F and grease an 11×7 or similar-sized baking dish.
Cut Hawaiian rolls into 1-inch cubes.
Layer half of the bread cubes into the baking dish, followed by half of the blueberries. Repeat the layering.
In a mixing bowl, whisk together eggs, half and half, sugar, and vanilla until well combined.
Pour the custard mixture evenly over the layered bread and berries. Press gently to ensure absorption without flattening.
Cover the dish with foil and bake for 40 minutes.
Remove foil and bake for an additional 20–30 minutes, until the top is golden and the center is slightly jiggly.
Dust with powdered sugar and serve warm with maple syrup if desired.

Notes

Use fresh or frozen blueberries; if using frozen, don’t thaw before baking.
To make ahead, refrigerate assembled casserole overnight and bake longer if needed.
For extra richness, replace blueberries with chocolate chips or add cream cheese chunks.
Store leftovers in the fridge for up to 3 days or freeze for up to 2 months.
Reheat gently in the oven or microwave to preserve moisture.
