In a mixing bowl, combine the softened cream cheese, shredded cheddar cheese, chopped dill pickles, and green onions. Mix until well incorporated using an electric mixer or a wooden spoon.
Add in the Dijon mustard, Worcestershire sauce, garlic powder, onion powder, and black pepper. Continue to mix until all the ingredients are smoothly combined.
Once everything is well mixed, use your hands to form the mixture into a ball shape. If the mixture is too sticky, you can chill it in the refrigerator for about 10 minutes before shaping.
Wrap the cheese ball tightly in plastic wrap. Refrigerate for at least 1 hour to allow the flavors to meld and the cheese ball to firm up.
Before serving, you can roll the cheese ball in chopped fresh dill for added flavor and presentation.
Serve the cheese ball with assorted crackers or vegetable sticks on a serving platter.
