This Christmas Morning Cinnamon Roll Casserole is a warm, shareable breakfast that feeds a crowd without anyone fighting over the last roll. Prep it the night before, stash it in the fridge, and pop it in the oven while everyone opens presents for a no-fuss holiday morning treat.
Don’t over-soak the rolls—more than 12 hours can make them mushy. Use room-temperature eggs and cream cheese to avoid lumps. Don’t skip brushing with butter for a crispy top. Let casserole rest 10 minutes after baking for custard to set. For gluten-free, use gluten-free canned cinnamon rolls. For dairy-free, use full-fat coconut cream, oat milk, dairy-free butter, and vegan cream cheese.
