Quick Answer

The best substitutes for buttermilk are: Milk + Lemon Juice, Milk + White Vinegar, Plain Yogurt. Each works differently depending on your recipe needs.

Buttermilk is a tangy, acidic dairy product that’s essential in many recipes. When you don’t have it on hand, these substitutes will save your recipe without compromising taste or texture.

Why Buttermilk Matters in Recipes

Buttermilk’s acidity reacts with baking soda to create lift in baked goods. It also tenderizes proteins in marinades and adds a distinctive tangy flavor to dressings and dips.

Best Uses for Each Substitute

The milk and acid combinations work best for baking where the chemical reaction is most important. Yogurt and sour cream substitutes excel in recipes where thickness and tanginess matter more than the exact acidity level.

For vegan options, non-dairy milk with acid creates a perfect plant-based buttermilk substitute that works in most recipes.
