How To Make Overnight Orange Roll Casserole:
Step 1: Prep the Pan: When you are ready to bake, preheat your oven to 375°F. Pour the 1/4 cup of melted butter into a 9×13-inch baking dish and swirl it until the bottom is fully coated.
Step 2: Layer the Rolls: Cut each refrigerated orange roll into quarters. Arrange the pieces evenly in the buttered dish.
Tip: Don’t pack the pieces too tightly! Leaving a little “breathing room” between the quarters allows the custard to seep into every nook and cranny, creating those irresistible soft, gooey centers.
Step 3: The Citrus Custard :In a medium bowl, whisk together the eggs, heavy cream, brown sugar, vanilla, and the zest and juice of your orange. Pour this mixture slowly over the rolls, ensuring they are all moistened.
