Buttermilk might not look like much, but it’s a quiet powerhouse in the kitchen. This tangy, cultured liquid has been around for centuries, originally left behind after churning butter. Today, it’s a go-to ingredient for adding flavor, moisture, and texture to all kinds of recipes. From breakfast favorites to savory mains, buttermilk plays well with both sweet and salty. The best part? It’s affordable, easy to find, and incredibly versatile. If you’ve got a carton sitting in your fridge and no idea what to do with it, you’re in the right place. These five ideas will show you exactly how to utilise buttermilk for cooking—and why it deserves a permanent spot in your kitchen.
1. Use Buttermilk to Make Extra-Fluffy Pancakes and Waffles
Buttermilk helps create the fluffiest pancakes and waffles you’ve ever tasted. It reacts with baking soda to form bubbles. Those bubbles expand during cooking, making your batter rise. The result is a lighter, airier texture that’s perfect for breakfast. To use buttermilk, replace regular milk in your recipe. Use the same amount, but expect better flavor and height. It also adds a subtle tang that pairs well with maple syrup. Some recipes even call for a mix of milk and buttermilk.
To upgrade basic batter, mix in mashed banana, cinnamon, or vanilla extract. Buttermilk holds up well to strong flavors. It complements them rather than clashing. For savory waffles, add chopped herbs, shredded cheese, or cooked bacon. You don’t need a fancy recipe to start. Just sub in buttermilk and see the difference. Your weekend brunch will thank you. Fluffy, golden, and packed with flavor—these are pancakes you’ll want to make every weekend.

2. Marinate Meats with Buttermilk for Tender and Juicy Results
Buttermilk is a secret weapon for tenderizing meat, especially chicken. Its acidity breaks down proteins without drying them out. The result? Juicier, more flavorful bites with every mouthful. To make a simple marinade, combine buttermilk with salt and spices. Let chicken soak for at least two hours. For the best results, marinate overnight in the fridge. The buttermilk gently softens the meat while adding a creamy tang.
Fried chicken is where this technique really shines. Southern cooks swear by it. After marinating, coat the chicken in seasoned flour. Fry until golden and crisp. The buttermilk helps the crust stick and adds extra crunch. You can also use it for pork chops, turkey, or even lamb. Add garlic, smoked paprika, or herbs for a flavor boost. The marinade clings to meat better than oil-based ones. Buttermilk doesn’t overpower. It enhances. For moist meat with a tasty edge, let buttermilk do the work. It turns everyday cuts into something memorable.
3. Bake Moist Cakes, Muffins, and Quick Breads
Buttermilk makes cakes and baked goods incredibly moist. It adds tenderness without making things heavy or greasy. It also brings out flavors like chocolate, lemon, and spice. Use it in banana bread, cornbread, or chocolate cake recipes. The acidity reacts with baking soda to help them rise. This means your baked goods get a light texture without extra fat.
Buttermilk also deepens flavor. Its tang balances sweetness, making your treats taste more complex. You’ll notice it especially in muffins and coffee cakes. To substitute, use the same amount as milk. If a recipe doesn’t call for buttermilk, add baking soda to balance it. A good ratio is 1/2 teaspoon soda per cup of buttermilk.
Want to make your own? Mix one tablespoon lemon juice or vinegar with a cup of milk. Let it sit for ten minutes. It won’t be quite the same, but it works in a pinch. For bakery-quality results at home, buttermilk is your best friend. You’ll get moist, soft, flavorful bakes every time.
4. Whip Up Creamy Dressings and Tangy Dips
Skip the store-bought bottles. Buttermilk makes easy, flavorful dressings and dips from scratch. It’s naturally creamy but much lighter than mayo or sour cream. Plus, it brings a bright, tangy taste to the table. Start with a basic buttermilk ranch. Combine buttermilk with mayo, garlic, lemon juice, and herbs. It’s fresher and cheaper than bottled versions. Add chives, dill, or parsley to boost flavor. A pinch of smoked paprika adds depth.
For dips, mix buttermilk with sour cream or yogurt. Stir in onion powder, scallions, or blue cheese. Serve with chips, veggies, or wings. The thinner texture makes it perfect for drizzling or dipping. You can also use buttermilk to loosen thicker sauces. Add a splash to hummus, tahini, or pesto to thin them out. It blends well without breaking.
Salad dressings benefit too. Mix it with olive oil and mustard for a zippy vinaigrette. Use it to mellow out spicy sauces or add a creamy touch to slaws. If your dressing feels heavy or dull, reach for buttermilk. It brightens everything it touches. You’ll want to keep it on hand for quick, tasty meals and snacks.
5. Make Tender Biscuits and Savory Scones
Buttermilk biscuits are a Southern staple for a reason. The acidity in buttermilk softens gluten and helps dough rise higher. The result is tender, flaky layers with rich flavor in every bite. To make biscuits, mix cold butter into flour, then add buttermilk. Don’t overwork the dough—keep it shaggy. That rough texture helps create flaky pockets as it bakes. Chill your dough before baking for the best rise.
Buttermilk also works in savory scones. Combine it with cheddar, green onions, or sun-dried tomatoes. Its tang complements strong cheeses and herbs. The dough is easy to work with and bakes up golden. If your biscuits usually turn out dry, buttermilk can fix that. Its moisture and acidity make a huge difference. You’ll get softer texture without sacrificing structure.
Want crisp tops? Brush with buttermilk before baking. It adds shine and helps toppings stick. For comfort food that feels homemade and special, buttermilk biscuits are hard to beat. They’re simple, satisfying, and endlessly customizable. Pair with jam, gravy, or eat warm from the oven—no regrets either way.
Bonus Tips: How to Store and Substitute Buttermilk
Buttermilk lasts longer than fresh milk but still needs care. Store it in the fridge and shake before using. If it smells sour or curdled, it’s probably past its prime. If you run out, make your own. Add lemon juice or vinegar to milk and let it sit. You can also use plain yogurt thinned with water. These substitutes work in most recipes.
Freeze buttermilk in ice cube trays to save leftovers. Use frozen cubes in batters, marinades, or dressings. Don’t drink frozen buttermilk plain—it’s best for cooking. Buttermilk powder is another option. Mix it with water as needed. It keeps well and saves fridge space. Whether fresh or from powder, buttermilk adds magic to your meals.
Final Thoughts: Buttermilk Deserves a Spot in Your Kitchen
Buttermilk may seem old-fashioned, but it’s incredibly versatile. From fluffy pancakes to juicy chicken, it makes food better. It adds lift, tenderness, and a touch of tang to everyday dishes. Try swapping it in your favorite recipes. Use it in baking, dressings, marinades, and more. It’s affordable, easy to use, and deeply flavorful. Once you start cooking with buttermilk, you’ll wonder how you ever lived without it.
