In a large mixing bowl, beat the softened cream cheese until smooth and creamy.
Incorporate the shredded cheddar cheese, green onions, onion powder, garlic powder, Worcestershire sauce, and salt, mixing until evenly distributed.
Place a large piece of plastic wrap on a flat surface and spoon the cheese mixture onto the center.
Gather the corners of the plastic wrap and twist to form the mixture into a compact sphere.
Refrigerate the wrapped cheese ball for at least 2 hours to allow the flavors to meld and the structure to firm.
Spread the chopped pecans on a shallow plate or tray.
Remove the cheese ball from the refrigerator, unwrap, and roll in the pecans until the exterior is fully coated.
Transfer to a serving plate and let stand at room temperature for 15 minutes before serving with crackers or vegetables.
