The easiest way is to let your cream cheese sit on your counter at room temperature for a few hours. You can chop the cream cheese into small chunks and let it sit on a plate or sheet pan for 45-60 minutes, depending on your environment and the size of the chunks. You could also place the foil-packed cream cheese in a bowl of warm water for 15-30 minutes, again depending on your environment. Be careful you don't want it to become melted. I do not recommend softening in the microwave as it can end up melting quickly.
