In a medium-sized mixing bowl, combine mayonnaise, buttermilk, sour cream, and lemon juice.
1 cup mayonnaise, 1/2 cup buttermilk, 1/2 cup sour cream, 1 tablespoon lemon juice
Add fresh parsley, fresh dill, garlic powder, onion powder, salt, and black pepper to the bowl. Whisk until combined.
1/2 tablespoon fresh parsley, 1 tablespoon fresh dill, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1/2 teaspoon salt, 1/2 teaspoon black pepper
Taste the ranch dressing and adjust the seasonings according to your preference. You can add more salt, pepper, or herbs if needed.
Cover the bowl with plastic wrap and refrigerate for at least 30 minutes to allow the flavors to meld. Serve and enjoy! If you'd like your ranch to be a little thinner add a splash of buttermilk and mix again before serving.
