01 - Combine softened cream cheese, shredded cheddar, and sour cream in a medium mixing bowl. Mix until completely smooth and creamy, ensuring no lumps remain.
02 - Add Dijon mustard, mayonnaise, Worcestershire sauce, garlic powder, smoked paprika, black pepper, and cayenne pepper if using. Stir thoroughly until all seasonings are fully incorporated into the cheese mixture.
03 - Taste the dip and adjust seasoning as needed. Add more black pepper or cayenne for additional heat if desired.
04 - Transfer the dip to a serving bowl. Sprinkle chopped chives or green onions evenly over the top as a garnish.
05 - Serve immediately with warm soft pretzels. Alternatively, cover and refrigerate until ready to serve. If chilled, allow to sit at room temperature for 10 minutes before serving to soften slightly.
