To make this Cucumber Cream Cheese Crack Dip gluten-free, confirm that the Worcestershire sauce is certified gluten-free or labeled gluten-free, as some brands may contain gluten-based additives or malt vinegar. The cream cheese, cucumber, green onions, onion powder, garlic powder, and salt are naturally gluten-free, but packaged seasonings and dairy products should still be checked for cross-contact. Serve with certified gluten-free crackers, chips, pretzels, or fresh vegetables. Use clean utensils, bowls, food processor parts, serving dishes, and prep surfaces to prevent gluten contamination.
