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.
