Can I make ranch dressing without buttermilk?
Yes. Mix equal parts sour cream and milk, or use plain yogurt thinned with a splash of milk. Add an extra 1/2 tsp lemon juice or vinegar for tang.
How long does homemade ranch dressing keep?
Store in an airtight container in the refrigerator for up to 7 days. The flavors meld and intensify after 1–2 hours.
Can I use fresh herbs instead of dried?
Yes, use 3 times the amount of fresh herbs (about 1 tbsp fresh parsley, plus fresh chives and dill). Fresh herbs will give a brighter flavor.
Is this dressing dairy-free?
No, this recipe contains mayo, sour cream, and buttermilk. For a dairy-free version, substitute with dairy-free mayo, coconut cream, and unsweetened plant milk.
Can I double or triple this recipe?
Yes, scale all ingredients proportionally. Store extra batches in separate airtight containers for up to 1 week.
