Step 4: The Soak (Optional Make-Ahead): If you’re prepping for the next morning, cover the dish tightly with foil and refrigerate up to overnight. If you’re baking immediately, let it sit for 10 minutes to absorb some liquid before putting it in the oven.
Step 5: Bake to Golden: Bake for 30/35 minutes until the rolls are puffed and golden but still have a slight “wobble” in the center. Let the casserole cool for 10 minutes.
Step 6: The Zesty Icing: Whisk together the powdered sugar, vanilla, orange zest, and juice. Stir in the melted butter last.
Tip: If you’re short on time, you can absolutely use the little icing tubs that come inside the orange roll cans. To elevate them, just stir in a pinch of fresh orange zest before drizzling!
