This Late Summer Vegetable Soup with Basil Pistou is one of my favorite soup recipes! This recipe makes great use of all that delicious summer produce like zucchini, corn, basil but with the exceptional flavor of a garlikcy basil pistou, that's added on top right before serving.

Healthy Summer Soup
Soups are a great way to get in a ton of vegetables in one meal. As they say, soup is good for the soul (any time of year). And now that Jersey corn and tomatoes are at their peak, I decided to take advantage of the opportunity to create a vegetable soup recipe which would highlight that exceptional flavor.
Roma Tomatoes
Many minestrone/vegetable soups call for canned tomatoes in their recipe. For this recipe, I use fresh organic Roma tomatoes. They add such amazing fresh flavor that only ripe summer tomatoes can bring. They do require just a bit of prep work before cooking to remove the skins, but it's well worth the effort.
How to Prep Roma Tomatoes for Easy Peeling:
(you need about 5-6 Roma tomatoes)
- Using a sharp knife, mark the tomatoes at the tip with "X".
- Place them in a pot of boiling water for one minute.
- Transfer to a bowl of ice water to cool.
- Peel.
What is Basil Pistou?
Although the fresh vegetables alone are insanely delicious, the basil pistou is what really makes this soup special.
Pistou is a French condiment made from basil and garlic and used like pesto. I throw in a little Italian flare, by adding in some Parmesan cheese as well. If you wanted to keep this dish vegan, just omit the cheese part.
Pistou can be stirred into pastas, slathered on sandwiches or used in vegetable soups, as I've done here (soup au pistou, in French). I suggest making large batches of it and freezing it in ice cube trays, to have whenever you need it.
How To Make the Basil Pistou
To a food processor, add basil leaves, garlic and parmesan cheese.
Begin to blend while at the same time adding in enough extra virgin olive oil to create a sauce. (sauce should not be too thin and not too thick...think pesto!)
Serving Options
There are a few options for serving the soup. For the kids, I added in some orzo pasta. My husband and I devoured it as is, with some toasted bread on the side...hello! You can add some beans to make it even more satisfying.
Either way, this little bowl of soup makes you feel like you're being instantly transported to Provence.
Not a bad way to travel, huh?
