In a mixing bowl, combine the mayonnaise, sour cream, and buttermilk. Whisk together until the mixture is smooth and creamy.
Add the garlic powder, onion powder, dried dill weed, dried parsley, dried chives, and a pinch of salt and pepper. If you’re using lemon juice, add it at this stage.
Whisk everything together thoroughly until the herbs and seasonings are fully incorporated into the dressing.
Taste your ranch dressing and adjust the seasoning if needed. You can add more salt, pepper, or lemon juice to suit your preferences.
Transfer the dressing to a jar or airtight container. Refrigerate it for at least 30 minutes to let the flavors blend together beautifully.
Serve as a dip, salad dressing, or sauce. Enjoy!
