Start by ensuring you have all your ingredients ready. This is a crucial first step. It saves time and keeps the process smooth. Measuring each item ahead of time lets you enjoy the cooking experience without scrambling.

In a mixing bowl, combine the cultured buttermilk, mayonnaise, and sour cream. Use a whisk to blend them until smooth. This creamy base is key to a rich dressing. You want it to be well blended, free from lumps.

Next, stir in the lemon juice, Dijon mustard, and finely minced garlic. These ingredients will elevate the overall taste. The mustard provides a subtle zest that complements the creamy base.

Now’s the time to fold in the freshly chopped dill, parsley, and chives. These herbs are vital for achieving that fresh ranch profile. Mix well to distribute the herbs evenly throughout the dressing.

Lastly, sprinkle in the sea salt and coarsely ground black pepper. Taste the dressing and adjust seasoning if desired. Don’t be shy to tweak it until it suits your palate!

Transfer the dressing to an airtight container, then refrigerate it for at least 30 minutes. This resting period allows the flavors to meld beautifully. It’s worth the wait, trust me!
