Except for a few college years, I have always lived on a farm. Growing up, we spent every summer day outside, well after a little morning-time TV. Many times it was some cartoon watching, but pretty soon I found Martha Stewart Living and from then on I was hooked. Each morning I would watch what was probably a summer rerun but I soaked it all in. (How’s this for a flashback?!) Ok, I totally went down a rabbit hole of old Martha episodes while searching for that link. Back to the grilled zucchini…

After my Martha fix, I’d help Mom with whatever gardening was on the day’s schedule: hoeing, watering, planting, canning or shelling peas (which I think I got 25 cents a cup for). Sometimes I would help Dad move animals from one building to another, but its no surprise that I was always more comfortable in the garden.

In her garden, Mom kept perfect, weed-free rows full of delicious vegetables. We didn’t often experiment with new recipes but instead stuck to the standards that Mom knew were good. Usually, our zucchini was made into a frittata or what we affectionately called “zucchini rounds”: little pancakes with Parmesan cheese and onion. Those. Were. Good.

Nowadays I love to find new ways to use the bounty my zucchini plants produce. This unique vegetable can take on almost any flavor you add to it, which is exactly why I love to grill it. The added flavor is multiplied with a basil dressing that would make anything edible. The way I eat today has changed, but the fact that I always have an abundance of zucchini has not!

Cook Time 10 minutes
Total Time 30 minutes
Servings 6 servings


For the salad

  • Stir and crumble on feta cheese.


  • This can be made up to one hour before serving with dressing. If making a day in advance, leave the dressing off and add before serving.

  1. Hi Kaleb,

    Just wanted to let you know this salad is great– so flavorful, easy, and I love that it is served cold. I added some torn up rotisserie chicken (not necessary, but nice). Definitely a great way to use up a bunch of zucchini!

    Thanks for all the fun content and ideas you post!


    1. So good to hear Cara! I love the idea of chicken if you want it more hardy. Salads like this are what I eat all summer. So glad you enjoyed!

    I made your grilled zucchini & onion salad for our July 4th cookout! It was so delicious, and was a big hit. I doubled it and there was plenty, with some left for us to enjoy a second day! Sorry, I didn’t take a photo of it!

    Easy, unique and delicious 😋 A really great salad for summer. We’ll definitely make it again!

  6. Yum!!! I love everything about your gardening and food prep! I always make my own dressings since I was a kid cooking with my mom. It’s the only way. I need one of those mixers, so cool😃

    GREAT recipe! I divided it into two containers as I made it, based on food preferences in our family. One likes zucchini, the other likes yellow squash so I made that substitution. Worked out great!

    Oh my gosh. Just made this last night. It is awesome! My husband overdid the zucchini on the grill, so they had a dark char. It may have been even better with the smokey flavor. The only swap I made was red wine vinegar rather than sherry vinegar. Once it was all tossed together, it became better than the sum of its parts! Thank you!
