Cover the container and place it on the center shelf of your refrigerator. As the oatmeal sits, it will slowly absorb the milk and become plump and tender. It will need 3-5 hours before it’s ready to eat. For the smoothest possible texture, leave it for 7-8 hours.  If the container you’ve selected doesn’t come with a built-in lid, secure a piece of plastic wrap or aluminum foil around the opening. Refrigerating overnight oats for longer than abut 10 hours may result in a soggy, inedible mess.
