Gather a mixing bowl, whisk, small spatula, and a jar or container with lid for storage.
Combine Greek yogurt and mayonnaise in the bowl. Whisk until the mixture is smooth and creamy, with a velvety texture that feels light on the palate.
Finely chop fresh parsley, dill, and chives. Add the herbs to the bowl and stir well to evenly distribute their vibrant green color and fresh aroma.
Mince the garlic finely or press it through a garlic press. Mix the pungent garlic into the dip, releasing a fragrant aroma.
Squeeze in about one tablespoon of fresh lemon juice for a bright, zesty kick. Stir thoroughly to combine all the flavors.
Season the dip with salt and freshly ground black pepper. Taste and adjust the seasoning to your liking, aiming for a balanced, tangy, and herbal flavor.
If you prefer a thinner consistency, stir in one to two tablespoons of buttermilk until the dip reaches your desired pourable texture.
Give the dip a final taste test and adjust herbs, lemon, or seasoning as needed. The dip should be vibrant, creamy, and well-balanced.
Transfer the dip to a jar or container with a lid. Cover and refrigerate for at least 30 minutes to allow flavors to meld and intensify.
Before serving, give the dip a gentle stir. It should be creamy, vibrant green, and bursting with fresh herbal aroma.
Serve chilled with veggie sticks, grilled chicken, or as a flavorful salad dressing. Enjoy the bright, velvety texture and herby zing with every bite!
