Creamy Pesto Salad Dressing

My Go-To Salad Dressing

There are three reasons I go to The Old Spaghetti Factory. The warm sourdough bread. The spumoni ice cream. And the creamy pesto salad dressing!

I loved it so much since I was a kid that I decided to figure out how to make it on my own and this is what I’ve came up with (many years ago).

And it’s been a family favorite every since.

I make this dressing probably more than any other. It’s one of the easiest dressing recipes, yet it’s so flavorful and satisfying.

  • Pour into an airtight container and refrigerate 30 minutes. Serve over green salad.

Homemade Salad Dressing doesn’t get any easier!

Where’s the Fresh Basil?

The term “Pesto” in the dressing is kind of funny to me because there isn’t even fresh basil in it but I stuck with the name all the same.

I love the signature flavor of the dried basil in the dressing and actually wouldn’t recommend substituting fresh here.

Can I Use the Buttermilk Substitute?

I don’t recommend using the milk + vinegar/lemon juice substitute for the buttermilk. I’ve tried and it doesn’t quite taste the same. Unfortunately.

I also love this dressing on a salad with chicken – for more of a main dish instead of a side dish. But it’s also perfect on a side salad to go with your spaghetti.

Ingredients

Instructions

  • Combine all ingredients in a medium mixing bowl. Whisk until well blended.
  • Pour into an airtight container and refrigerate 30 minutes. Serve over green salad.

Notes

  • *Don't use stale dried basil (as in one that has been sitting in the cupboard for a year or two). A fresher pack is best. This is also delicious with fresh basil, 1/3 cup finely chopped.
  • **I use the the pokey side of a box grater to get the fine grate. Just be careful. Also store bought grated parmesan such as Kraft can be used as well when in a rush.

    sounds good! Could you substitute dill weed for the basil? A local restaurant has a lemon dill dressing that sounds like this one. I will make this recipe regardless!

    Oh my…this is tasty and I haven’t even let it sit an hour…I used kefir in place of buttermilk as I have no buttermilk. I may add a wee bit of lemon juice to give it a more buttermilk like “zing”.

    The Spaghetti Company is my absolute favorite restaurant because of that dressing and the mizithra cheese! My mom and sister actually go there and buy their dressing and cheese to take home and use! I can’t wait to try this to see how close it is!
