Start by carefully measuring each ingredient. In a medium bowl, mix the mayonnaise, buttermilk, and sour cream. Having everything ready will help you mix smoothly and reduce mistakes.
Use a whisk to blend the mayonnaise, buttermilk, and sour cream until pale and smooth. Aim for a creamy base without any lumps or streaks.
Once the wet ingredients are mixed well, it's time to add flavor. Add garlic powder, onion powder, dried dill, dried parsley, black pepper, salt, and paprika. Whisk again until the seasonings are fully mixed into the creamy base.
Now, taste the dressing. If it needs more flavor, adjust the salt or pepper. If you like a stronger taste, add a bit more garlic powder.
After adjusting, cover the bowl with plastic wrap or pour the dressing into an airtight container. Refrigerate for at least one hour. This helps the flavors blend, and the texture becomes thicker and creamier.
When you are ready to use the dressing, stir it well to mix any separation. Serve it in a small dish for dipping or pour it over wings, fries, or salad. This dressing is delicious and versatile for any meal.
