📝 About This Recipe

Born in the rugged mountains of Santa Barbara, California, this authentic West Coast ranch is a world away from the bottled variety. It balances the tangy brightness of real cultured buttermilk with a rich, velvety base and an abundance of fresh, aromatic green herbs. This dressing is the definitive American condiment—creamy, herbaceous, and soul-satisfyingly fresh.

🥗 Ingredients

The Creamy Base

  • 1 cup Mayonnaise (high-quality, preferably avocado oil or classic egg-based)
  • 1/2 cup Sour Cream (full-fat for best texture)
  • 1/2 cup Buttermilk (shaken well, cold)

The Fresh Garden Herbs

  • 2 tablespoons Fresh Chives (finely minced)
  • 2 tablespoons Fresh Flat-Leaf Parsley (leaves only, finely chopped)
  • 1 tablespoon Fresh Dill (stems removed, finely chopped)

Aromatics and Seasoning

  • 1 clove Garlic (grated into a paste or very finely minced)
  • 1 teaspoon Shallot (minced into a fine paste)
  • 1 teaspoon Lemon Juice (freshly squeezed)
  • 1/2 teaspoon Worcestershire Sauce (for umami depth)
  • 1/2 teaspoon Dijon Mustard (adds a subtle sharp note)
  • 1/2 teaspoon Onion Powder
  • 1/2 teaspoon Kosher Salt (adjust to taste)
  • 1/4 teaspoon Black Pepper (freshly cracked)
  • 1/8 teaspoon Dried Tarragon (optional, for a classic California touch)

👨‍🍳 Instructions

  1. 1

    Begin by prepping your fresh herbs. Finely mince the chives, parsley, and dill until they are almost like a coarse paste to ensure their oils release into the dressing.

  2. 2

    On a cutting board, mince the garlic clove, then sprinkle a pinch of salt over it. Use the side of your knife to mash it into a smooth paste.

  3. 3

    In a medium-sized glass mixing bowl, whisk together the mayonnaise and sour cream until completely smooth and no lumps remain.

  4. 4

    Slowly stream in the buttermilk while whisking constantly. The consistency should be pourable but thick enough to coat a spoon.

  5. 5

    Add the garlic paste and minced shallots to the creamy mixture and whisk vigorously to distribute the aromatics.

  6. 6

    Stir in the fresh chives, parsley, and dill. You will immediately see the dressing take on that classic speckled green appearance.

  7. 7

    Add the lemon juice, Worcestershire sauce, and Dijon mustard. These ingredients provide the 'zing' that cuts through the richness of the fats.

  8. 8

    Sprinkle in the onion powder, kosher salt, freshly cracked black pepper, and the optional dried tarragon.

  9. 9

    Whisk everything together for about 30 seconds to ensure the spices are fully hydrated and integrated.

  10. 10

    Taste the dressing. If you prefer it tangier, add another drop of lemon juice. If it's too thick, add buttermilk one tablespoon at a time.

  11. 11

    Transfer the dressing to a glass jar or airtight container. This is crucial for maintaining a clean flavor.

  12. 12

    Refrigerate for at least 30 minutes before serving. This 'resting period' allows the dried spices to bloom and the fresh herb flavors to meld with the dairy.

💡 Chef's Tips

Always use fresh herbs over dried; the vibrant green color and grassy notes are what define a true West Coast ranch. If you don't have buttermilk, you can make a quick substitute by adding 1 teaspoon of lemon juice to 1/2 cup of whole milk and letting it sit for 5 minutes. For a thicker 'dip' consistency, reduce the buttermilk by half and increase the sour cream. Avoid using a blender or food processor, as this can over-process the herbs and turn the entire dressing a pale green color rather than speckled. Store in the coldest part of your fridge for up to 1 week; the flavors will actually improve on day two.

🍽️ Serving Suggestions

Serve alongside a platter of crisp, ice-cold crudités like Persian cucumbers, radishes, and snap peas. Drizzle over a classic Wedge Salad with iceberg lettuce, crispy bacon bits, and cherry tomatoes. Use as a cooling dip for spicy Buffalo-style cauliflower wings or traditional chicken wings. Pair with a chilled glass of California Chardonnay or a crisp Sauvignon Blanc to complement the herbal notes. Slather onto a grilled chicken club sandwich with avocado for the ultimate California lunch.
