Yes, it could be made a day ahead of time, just reheat it in the oven or microwave, but make sure the crescent rolls don't overcook during the reheat. You can also prep the crescent roll stuffing before baking. Make the stuffing per the directions until it needs to go into the oven. Cover the uncooked stuffing and store it in the fridge, for up to 24 hours, until ready to bake. Remove cover and bake per recipe directions.
