This easy overnight cinnamon roll French toast casserole is a quick and delicious breakfast that combines the indulgence of cinnamon rolls with a creamy custard soak, perfect for busy mornings or leisurely brunches.
Use room temperature eggs and dairy for better custard absorption. Cut cinnamon rolls into quarters for even soaking. Tent with foil if the topping browns too quickly. Let the casserole rest before serving for easier slicing. Leftovers reheat well in oven or microwave with a damp paper towel.
