Can I make ranch dressing without buttermilk?
Yes. Mix equal parts sour cream and milk, or use Greek yogurt thinned with milk. The tanginess will shift slightly but the dressing will still work well.
How long does homemade ranch dressing last?
Store in an airtight container in the refrigerator for up to 5 days. The flavors meld and intensify after 1–2 hours, so make it ahead if possible.
Can I use fresh herbs instead of dried?
Yes, use 3 times the amount of fresh herbs (roughly 3/4 tsp of each). Fresh dill, parsley, and chives will give a brighter flavor but may slightly thin the dressing.
Is this recipe dairy-free?
No, it relies on mayo, sour cream, and buttermilk. For a dairy-free version, substitute with vegan mayo, coconut cream, and unsweetened plant milk, though the texture will differ.
How do I thicken or thin the dressing?
Add more sour cream or mayo to thicken; add buttermilk or milk to thin. Adjust in small increments to reach your desired consistency.
