Substitute for Sour Cream in Ranch Dressing
Best Substitutes
| Sour Cream Substitute | Rating | Substitution Ratio for Ranch Dressing | Ideal For | Flavor | Adjustments |
|---|---|---|---|---|---|
| Full‑fat Greek yogurt | Best | 1:1 | Thick dip‑style ranch or classic spoonable dressing | Bright tang, clean dairy flavor | Thin with 1–3 tbsp buttermilk or milk if needed; salt to taste |
| Mayonnaise + buttermilk blend | Good | 2/3 cup mayo + 1/4–1/3 cup buttermilk per 1 cup sour cream | Pourable, classic American ranch | Classic ranch flavor, slightly richer, very creamy | Add buttermilk gradually to reach thickness; reduce any extra liquid elsewhere |
| Crème fraîche | Good | 1:1 | Silky, restaurant‑style ranch with mild tang | Rich, buttery, less tangy than sour cream | Add 1–2 tsp lemon juice or vinegar to match tang |
| Blended cottage cheese (small‑curd, 4%) | Good | 1:1 after blending until smooth | High‑protein, lighter ranch dips | Mild dairy, slightly savory; less tang | Blend smooth; add 1–2 tsp lemon juice; pinch sugar to balance |
| Silken tofu (blended) | Works | 1:1 after blending until creamy | Dairy‑free/vegan, pourable ranch | Neutral; needs extra acid and salt | Add 2–3 tsp lemon juice, 1 tsp vinegar, extra salt; a little oil for richness |

"Swapping a bit of sour cream for part of the mayo made their ranch taste better—creamier and tangier without going full 'dip' thick."
Reddit user (r/Cooking)•General ranch dressing discussion"A former steakhouse prep cook shared their house ratio as 2:1:1 sour cream:buttermilk:mayo; others warned that pushing sour cream and buttermilk too far can make the dressing taste harshly sour."
Reddit users (r/Cooking)•Troubleshooting “restaurant-style” ranch at home"For thicker, more flavorful dressing, replace 2–4 tablespoons of the buttermilk with sour cream; it bumps body without breaking the classic profile."
Reddit user (r/Cooking)•Tips for dialing in texture"A cook’s sour cream–buttermilk ranch tasted great fresh but turned unpleasant the next day; replies blamed fresh garlic/chives in dairy getting ‘skunky’ over time and suggested adding alliums right before serving."
Food52 Hotline member•Make-ahead gotcha"If you’re out of buttermilk, a spoonful of sour cream plus a splash of cream worked as a passable stand-in for the tang and thickness."

Choosing the Right Substitute
Sour cream in ranch provides three essentials: tang, creamy fat, and thickness that suspends herbs and spices. When choosing a substitute, match body (thick vs. pourable), brightness (acid/tang), and richness so the dressing emulsifies and clings rather than turning watery. Adjust acidity with lemon or vinegar and tweak thickness with a splash of buttermilk or milk to hit your target texture.
Our Top Choice: Full‑Fat Greek Yogurt
Use it 1:1 for the closest balance of tang and thickness. It holds herbs well, tastes familiar, and can be thinned with a little buttermilk for a classic pour or left thick for a chip‑ready dip.
A Close Alternative: Crème Fraîche
Crème fraîche matches the lush mouthfeel of sour cream but is milder. Add a teaspoon or two of lemon juice or white wine vinegar to brighten it to ranch territory.
For Classic Flavor: Mayonnaise + Buttermilk Blend
Replacing sour cream with a 2/3 mayo and 1/4–1/3 cup buttermilk mix yields the quintessential creamy, pourable ranch profile. Add the buttermilk gradually to dial in thickness and keep the dressing from thinning too much.
For Higher Protein, Lighter Feel: Blended Cottage Cheese
Blend small‑curd cottage cheese until silky for a thick, protein‑rich base. It’s less tangy, so add lemon juice and a pinch of sugar to balance the savory curds.
For Dietary Restrictions: Silken Tofu
Blended silken tofu makes a neutral, dairy‑free base. Boost acidity and salt, and whisk in a teaspoon or two of neutral oil to mimic dairy richness before adding ranch seasonings.
