In a medium bowl, whisk together the sour cream and cream cheese until smooth and well combined.
Stir in the minced dried onion, Worcestershire sauce, garlic powder, onion powder, and pepper until evenly distributed.
Gently fold in the green onions.
Cover and refrigerate the dip until the flavors meld and the dip is cold, at least 30 minutes or up to 2 days.
Serve chilled with potato chips or other dippers of your choice.
Refrigerate leftovers in an airtight container for up to 3 days.
