This Cinnamon Roll Casserole is a quick, festive, and comforting brunch dish perfect for Christmas morning. It combines gooey cinnamon rolls with a rich custard base and a sweet vanilla glaze for a crowd-pleasing treat.
For best results, use room temperature eggs and milk. You can assemble the casserole the night before and bake fresh in the morning. For gluten-free or dairy-free adaptations, use appropriate cinnamon rolls and milk substitutes. Let the casserole cool for 10 minutes before serving for easier slicing and better texture. Leftovers keep well in the fridge for up to 3 days and can be frozen for up to 1 month.
