In a medium bowl, whisk together the mayonnaise, Greek yogurt, lemon juice, olive oil, dill, parsley, garlic, salt, and black pepper until smooth.
Taste and adjust the seasonings. Add more lemon juice for extra tang, a pinch of red pepper flakes for heat, or more herbs for freshness.
Cover and refrigerate for at least 30 minutes so the flavors can blend.
Notes
This recipe yields about 1 cup
Success Tips
Use high-quality ingredients: A good mayonnaise and full-fat Greek yogurt make the dressing richer and creamier.
Fresh herbs make a difference: You can swap in fresh dill and parsley if you have them. Use double the amount and chop them finely before mixing.
Storage Instructions
Store the dressing in an airtight container in the refrigerator for up to 5 days. It will thicken slightly after chilling. If needed, whisk in 1 to 2 teaspoons of water or milk to thin it out.
