Buttermilk herb dressing is a great way to use up a cup of leftover buttermilk to make an easy homemade salad dressing with garden fresh herbs or your favorite dried herbs from the pantry.

When I buy a container of buttermilk to make my favorite homemade buttermilk waffles or buttermilk biscuits, I always seem to have just a cup leftover.

One of my favorite ways to use it up is to make homemade buttermilk herb dressing for salads with chicken or leftover pork and lots of fresh veggies.

This easy dressing recipe is perfect because I always have the remaining ingredients in my fridge and it is flexible enough to go with whatever fresh herbs or dried herbs I feel like using.

My favorite fresh herb to use is dill but during the winter I'll often use a dried Italian herb blend instead.

Why This is the Best Recipe

I absolutely love this easy buttermilk herb dressing and think it is the best recipe because:

  1. Uses Up Leftover Buttermilk: It only takes a cup, so it is the perfect way to use the last of the container.
  2. Easy Ingredients: I almost always have everything else on hand but it is flexible enough to swap out the seasonings.
  3. Flexible: You can use your favorite herbs here, fresh or dried.
  4. Light but Creamy: Compared to bottled dressings, the texture of this recipe is perfect for drizzling over fresh, crispy vegetables.


The ingredients to make the homemade dressing are on the counter.

Look at just how few things you need to make this!

  • Buttermilk: I love using organic buttermilk because it always lasts longer in the fridge so I have more time to use it up!
  • Mayonnaise: You can use light made with olive oil or regular.
  • Dijon Mustard
  • Minced Garlic
  • Olive Oil
  • Green Onions:
  • Lemon
  • Fresh or Dried Herbs: Be sure to read my notes on which ones to choose below.

Whisk the Dressing

First, prep all the ingredients but the buttermilk and herbs.

Add the mayo, mustard, olive oil, lemon juice, garlic, and chopped green onions to a mixing bowl. Whisk them together to combine the flavors.

The green onions and dressing ingredients are in a big mixing bowl.

Add the Buttermilk

Next, drizzle in the buttermilk to the mixing bowl. Pour slowly and stop when your desired texture has been reached.

You may or may not need the entire cup of buttermilk.

The dressing has been whisked and the cup of buttermilk is about to be drizzled in.

I like our dressing to be easy to drizzle, not too thick.

Herb Variations

Finally, season the buttermilk dressing with your favorite herbs.

I had some fresh dill on hand the day I made this, so I added a tablespoon of chopped dill.

When my patio herb garden is in full swing, I might also use:

  • Fresh basil
  • Fresh thyme
  • Fresh tarragon
  • Fresh chives
  • Fresh dill: If you use dill, be sure to save some to make my easy dill dip for veggies, too!

However, sometimes fresh herbs aren't available and you don't feel like running out to the store.

You can make this herb dressing with dried herbs, too.

I love to use:

  • Dried Italian herb blend
  • Dried Mediterranean herb blend
  • Dried ranch seasoning

Serving Suggestions

A green salad with chicken, tomatoes, and croutons has been drizzled with the buttermilk herb dressing.

This buttermilk herb dressing tastes great as a salad dressing with chunks of leftover chicken or pork.

Don't have leftovers? Just cook some chicken tenderloins in the air fryer and chop them up.

Pair it with my homemade cornbread croutons for a surprisingly easy but very impressive salad if you're serving company. Or add a homemade buttermilk drop biscuit for the bread roll.

I've also used this herb dressing as a dip for fresh vegetables or even potato chips or fried pickles.

You could use it as a chicken marinade for baked chicken to keep it nice and juicy.

Storage Tips

Store the prepared dressing in an airtight container for up to 3 days.

While buttermilk itself freezes well, don't try to freeze this prepared dressing because the herbs and green onions may affect the texture as it thaws.
