Allow the cream cheese to soften (come to room temperature). Leave it on the counter for about an hour before making the dip. Or soften it in your microwave.
Soak the green onions in cold water, then dry them well with paper towels. Remove and discard about the top half of the greens and the root ends. Chop the remaining green onions into thin slices.
In a medium bowl, combine the softened cream cheese, dried beef, green onions, sour cream, chives, garlic powder, Worcestershire sauce and black pepper. Use a spatula to stir until well combined. Or use an electric hand mixer.
Store the dip in an airtight container in the refrigerator for at least one hour, to allow the flavors to harmonize together.
This dip can be made up to one day in advance of serving.
Serve the dip with your favorite crackers and/or fresh cut veggies. You could also serve it in a pumpernickel or rye bread bowl, with bread cubes to dip.
Notes
Make it a cheese ball: Transfer the dip to the middle of a sheet of plastic wrap. Gather the wrap around the dip and twist to form a ball. Refrigerate for at least one hour to firm up. Roll the cheese ball in additional chopped dried beef and chopped chives before serving.Make hot dried beef dip: Spread the dip into a small oven-safe baking dish or pie plate. Top with chopped pecans if desired. Bake at 350 degrees F for about 20 minutes.
