In a medium bowl, stir together the Greek yogurt, mayonnaise, apple cider vinegar, chopped fresh dill, onion powder, garlic powder, cayenne pepper, salt, and black pepper until smooth and well combined.
Cover and refrigerate for at least 30 minutes to allow the flavors to develop. The dip may also be made up to 48 hours ahead.
Stir the dip before serving. Taste and adjust the seasonings as needed. Serve chilled with fresh vegetables, crackers, or chips.
Notes
Fresh vs. Dried Dill: For ¼ cup fresh dill, start with 1 tablespoon plus 1 teaspoon dried dill. Chill, taste, and add more if desired. (Test this substitution before finalizing.)
Sour Cream Substitute: Replace the Greek yogurt with an equal amount of sour cream for a richer, more traditional dip.
Lemon Variation: Fresh lemon juice can be substituted for the apple cider vinegar.
Adjust the Heat: Reduce or omit the cayenne for a milder dip, or add a little extra for more kick.
Make Ahead: Prepare up to 48 hours ahead and refrigerate until serving.
Storage: Store covered in the refrigerator for up to 4 days.
Freezing: Not recommended because the dip can separate when thawed.
Serving Ideas: Enjoy with fresh vegetables, chips, crackers, bread, or as a sandwich spread.
