This easy overnight cinnamon roll casserole is a quick and comforting breakfast that combines cinnamon rolls with a custard soak, perfect for cozy mornings and crowd-pleasing brunches.
Do not skip the overnight soak for best texture. Use room temperature eggs and milk to avoid curdling. Cut cinnamon rolls into evenly sized pieces for even baking. Do not cover casserole while baking to maintain a golden crust. Adjust baking time if using a different size baking dish. Optional nuts can be added before baking for crunch. Leftovers keep well refrigerated for 3-4 days and can be reheated in microwave or oven.
