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 - Incorporate Dijon mustard, mayonnaise, Worcestershire sauce, garlic powder, smoked paprika, black pepper, and cayenne pepper if using. Stir thoroughly until all seasonings are evenly distributed throughout the cheese base.
03 - Taste the dip and adjust seasoning as preferred. Add additional salt, pepper, or spices to achieve desired flavor profile.
04 - Transfer the dip to a clean serving bowl. Sprinkle chopped chives or green onions evenly over the top as garnish.
05 - Serve immediately with warm soft pretzels. If refrigerated, allow dip to sit at room temperature for 10 minutes before serving for optimal texture and flavor.
