This Pesto Vinaigrette is bursting with summer basil flavor. Easy to make with the use of store-bought pesto, this dressing will be your go not just in summer but any time you’re craving that sweet summer basil.
If you’re looking for the perfect quick and easy dressing that is packed with summer flavor, then this Pesto Vinaigrette is exactly what you need.
This recipe is crazy easy to make thanks to store bought pesto. During the summer it’s pretty easy and cost effective to make your own pesto. During the winter months when you want just a little bit summer to spruce up those dark winter days, store bought pesto can be your best friend. I use it for pastas, for sandwiches, pizzas and now this pesto vinaigrette. I’ve been buying mine at Costco and it’s becoming one of my favorite products. I even make special trips to Costco for it when I run out. It’s pretty good, guys.

My favorite part of this vinaigrette is just how lusciously smooth it is. Almost creamy but without a hint of cream. Let’s discuss what you’ll need to make it.
What ingredients do you need to make Pesto Vinaigrette?
Because you’ll be using store bought pesto for this recipe, you’ll only need a few ingredients:

- PRE-MADE PESTO You can certainly make your own or you can buy your favorite brand.
- VINEGAR: Every vinaigrette dressing calls for, you guessed it, vinegar. This recipe calls for white wine vinegar which I think adds the perfect bright flavor. A reader below suggested that she preferred Red Wine Vinegar in this recipe which is a great substitute! Don’t use distilled or apple cider as both of those will be to harsh. And balsamic will alter the color.
- GARLIC: Yes, your store bought pesto is probably going to already have garlic in it but I like adding a touch more to give it a bit more garlickly flavor.
- EXTRA VIRGIN OLIVE OIL: Always use the best quality extra virgin olive oil that you have on hand when making vinaigrettes. The pesto itself has olive oil but the addition of more olive oil helps emulsify this dressing giving it a creamy consistency.
SALT AND PEPPER
How to make Pesto Vinaigrette with Premade Pesto:
You’ll need a food processor to make this. I use this mini food processor from KitchenAid and it’s one of my favorite kitchen tools!

Combine pesto, garlic and vinegar in a food processor and process until smooth. 
With the food processor running, slowly drizzle the olive oil in through the small opening in the top of the lid until the dressing is emulsified. 
Season to taste with salt and pepper.
STEP #1: Combine pesto, garlic, and vinegar together in the food processor and process until smooth.
STEP #2: With the food processor running, slowly drizzle the oil in through the small opening in the top of the lid. Continue processing until the vinaigrette is emulsified.
STEP #3: Season to taste with salt and pepper.
Ways to use Pesto Vinaigrette:
I have made this pesto vinaigrette a few times now and it is always a huge hit. It is of course great on green salads, but if you have a friend who is not a huge fan of beets, drizzle this over some roasted beets to change their mind. And if you want to make a festive spring crostini, spread some goat cheese on toast and drizzle with vinaigrette. Whatever you do, make this pesto vinaigrette today.

Storage and Leftovers:
I store this in the refrigerator in a mason jar. It usually lasts several days. Keep in mind that the olive oil will solidify in the cool temperatures so you’ll want to bring it up to room temperature before serving.

Like making your own dressings? ME TOO! Here are some of my favorite dressings to make at home:
- Homemade Caesar Dressing without raw eggs is perfect for those who are a bit squeamish about using them!
- Can’t go wrong with Buttermilk Ranch. Like ever.
- I use this Honey Mustard Dressing as a salad dressing but also as a marinade for chicken and a dip for chicken strips. It’s a family favorite!

I prepared it for my family and everyone just loved it especially my husband. Thanx for sharing.
i’ve now tried this with both balsamic and red wine vinegar! the balsamic produced a really weird color, but tasted fantastic. the red wine vinegar was very good and not too sharp. i think i preferred the flavor of the balsamic, but i could never serve it to anyone because the color was ghastly. the red wine vinegar is the winner for me. thank you for posting this recipe – it’s allowed me to experiment and find the right fit!
Yum! Looks like it would go well with some fresh tomatoes and olives! Can’t wait to try this recipe!
I love that you tried it with kale and walnuts! What a great idea!
Love this recipe, which I’ll make again and again. I made it tonight with what I had on hand (kale and walnuts) and I couldn’t believe how quickly in came together and how wonderful the flavor is. I’m excited to start experimenting with nut and herb combinations.
Thank you for your feedback Christie! Let me know if you try it with the other vinegars. I was concerned about balsamic because of color but I bet red wine vinegar would be good too!
this was ok as written, but the white vinegar taste was too strong. i will probably try it again with a milder vinegar, maybe red wine or balsamic.
Ooooh I have to try this asap! I’ve been trying to eat healthy and this presto vinaigrette would be perfect for my daily salads. :) Looks yummy!
Holy moly! I can’t believe how easy it is to make! MUST TRY ASAP!
I love Costco’s pesto and have a big thing of it in the fridge! I’ll have to try this vinaigrette with it for sure!
Yes! One of my favorite kinds of dressing!!!
Oh, how delicious! I’m gonna add this to my lunch salad today.
