This lightened-up buttermilk ranch dressing is creamy, tangy, and full of fresh herbs. Made with Greek yogurt, fat-free sour cream, and low-fat buttermilk, it captures the classic ranch flavor with far fewer calories than the traditional version. It’s quick to whisk together, makes a great salad dressing or veggie dip, and improves in flavor after a few hours in the fridge.
Lightened Up Buttermilk Ranch Dressing
Homemade ranch is simple to make and tastes fresher than store-bought bottles. This recipe is adapted from an older Farmgirl Fare recipe and has been a family favorite for years. It’s versatile — spoon it over a green salad, use it as a dip for raw vegetables, or try it as a sauce for wraps, grilled chicken, or roasted potatoes.
Why This Lightened Ranch Dressing Works
This version keeps the flavor of classic ranch while cutting back on calories and fat. The balance of creamy dairy, savory seasonings, and bright herbs gives you the ranch profile you expect without relying on a packaged seasoning mix.
- Creamy but lighter: Fat-free Greek yogurt and fat-free sour cream form a rich base with fewer calories than a full-fat dressing.
- Classic savory flavor: Garlic powder and onion powder provide that familiar ranch backbone while fresh parsley and chives brighten each bite.
- Versatile: Use as a dressing, dip, or spread — adjust thickness with more or less buttermilk depending on the use.
- Make-ahead friendly: The dressing tastes better after resting in the fridge for a few hours, which allows the flavors to meld.
Low-fat Buttermilk Ranch Dressing — Recipe
Yield: 13 servings (about 1/4 cup per serving). Prep time: 10 minutes.
Ingredients
- 3/4 cup fat-free sour cream
- 3/4 cup fat-free Greek yogurt
- 1/3 cup light mayonnaise
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 tablespoon chopped fresh chives
- 1 tablespoon chopped fresh parsley
- 1 teaspoon salt
- Freshly ground black pepper, to taste
- 1–2 tablespoons white balsamic vinegar (start with 1 tbsp and adjust)
- 2 cups 1% low-fat buttermilk (adjust for desired thickness)
Instructions
- In a medium bowl or large measuring cup, whisk together the sour cream, Greek yogurt, light mayonnaise, garlic powder, onion powder, chopped parsley, chopped chives, salt, and several grinds of black pepper until smooth.
- Stir in the white balsamic vinegar, then slowly whisk in the buttermilk until the dressing reaches your preferred consistency. For a thicker dip, use a bit less buttermilk; for a pourable dressing, add a little more.
- Taste and adjust seasonings — add another tablespoon of vinegar for more tang, or more herbs, salt, and pepper as desired. Refrigerate for at least 1–2 hours when possible; the flavors become more rounded with resting time.

Tips from the Test Kitchen
- Choose fresh herbs: Fresh chives and parsley make a noticeable difference. Dried herbs are less vibrant in flavor and color.
- Make ahead: Prepare the dressing a few hours before serving to allow the flavors to meld and intensify.
- Adjust thickness: For dipping use less buttermilk; for a pourable dressing add more a little at a time until you reach the right consistency.
- Keep it fresh: Store in an airtight container in the refrigerator and use within about 5 days for best flavor.
Storage
Transfer the dressing to a sealed jar or airtight container and refrigerate. Stir or shake before serving. Because it contains fresh dairy and herbs, enjoy within five days for optimal taste and quality.
