How to Grill Zucchini - Perfect Every Time! found on KalynsKitchen.com

For most of my life I was kind of lukewarm about zucchini. When I was a kid, my mom would dip it in egg and fry it, something I liked ok, but didn’t love. It wasn’t until I discovered how great grilled zucchini can taste (and my mom started making creamed” zucchini) that I really started appreciating the zucchini that spring up overnight in the garden.

This method for How to Grill Zucchini That’s Perfect Every Time is a recipe you should use in the summer when the zucchini are fresh from the garden or farmer’s market. Since you want rather thick slices of zucchini, it’s the perfect way to cook those that miss getting picked and get a bit too large.

Zucchini can be easily cooked on a stove-top grill pan with ridges if you don’t have an outside grill. The same type of preparation is also good on yellow summer squash or eggplant. Once you’ve tried it, I promise this way of cooking zucchini will become a part of your regular summer rotation for the grill. (If you’re making this recipe to be Paleo, Vegan, or Gluten-Free, be sure to choose a salad dressing that works with that eating plan.)

I like to use a mandoline to slice the zucchini on the diagonal for more surface area on the grill. Mix together your favorite vinaigrette, garlic powder, and a few teaspoons of dried Italian herbs like basil, oregano, or rosemary. Put the zucchini in a single layer in a heavy Ziploc bag, dump in the marinade, and let it marinate in the fridge for several hours (or all day while you’re at work.)

When it’s time to cook, let the zucchini drain well in a colander placed in the sink while you preheat the grill to medium-high.

Lay zucchini on an angle to the grill grates, and if you want those criss-cross grill marks, rotate each piece after 3-4 minutes. Then turn and cook a few minutes more on the second side. I cook zucchini about 10-12 minutes total, or slightly less if you want some crunch left in them.

How to Grill Zucchini That's Perfect Every Time!

This post can teach you How to Grill Zucchini  and this perfect grilled zucchini is a side dish all summer long.


  • 2 zucchinis 10-12 inches long, sliced in slices 1/2 to 5/8 inch thick (see notes)
  • 1/2 cup of your favorite vinaigrette salad dressing
    (for South Beach choose dressing with less than 2 grams of sugar per serving (see notes)
  • 1 tsp. garlic powder or garlic puree (optional, but good)
  • 1-2 tsp. dried oregano, basil, thyme, rosemary, or a combination (optional)


  1. Cut zucchini into slices, making sure the slices are the same thickness.
  2. Combine salad dressing with garlic powder and dried herbs of your choice, if using. (I like this both with and without the extra flavorings. This is one place where fresh herbs are not better.)
  3. Put zucchini slices into Ziploc bag, pour in marinade and let zucchini marinate in the fridge 4 hours or longer, even as long as all day if desired.
  4. When you’re ready to cook, drain zucchini into a colander placed in the sink.
  5. To cook zucchini, preheat grill to medium-high. (You can only hold your hand there for 3-4 seconds.) You can spray the grill with non-stick spray if desired, but you don’t really need it.
  6. Place zucchini on grill on a diagonally to the grill grates, keeping a spray bottle handy for taming any flames that shoot up from the oil in the marinade.
  7. After 3 or 4 minutes, check for grill marks, and when you see them rotate zucchini going the opposite direction. Cook 3 or 4 more minutes after you’ve rotated.
  8. Turn zucchini to second side and cook a few minutes more, or until zucchini is starting to soften, with the outside slightly charred and browned.
  9. Season with salt and fresh ground black pepper and serve hot.


I like to use a mandoline slicer to slice the zucchini on the diagonal. I like Newman’s Own Original Recipe Olive Oil and Vinegar Dressing dressing for this recipe. (affiliate links)

This is an easy recipe that Kalyn came up with and has used for years.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Zucchini or other low-glycemic summer vegetables grilled this way are perfect for any low-carb or low-glycemic eating plan as well as any phase of the South Beach Diet, as long as you use low-sugar vinaigrette. I like Newman’s Own Olive Oil and Vinegar or Newman’s Own Balsamic Vinaigrette which has only 1 gram of sugar per serving. For vegan, Paleo, or Whole 30, be sure to choose an approved dressing.

  3. Hey Erin, how fun hearing from you! Hope you enjoy the zucchini!

  4. Hi Kalyn! I'm making this grilled zucchini and yellow squash tonight. Im so glad I stumbled upon this blog, you and my mom Lois go way back 🙂 I remember playing at your house as a kid!!

  5. Jeff, I cook them with the grill closed (unless I'm taking photos.) But it will work either way, just cook a few minutes longer if you keep the grill open.

  6. Hi Kalyn, I will be trying these this weekend. Do you keep the grill cover up while cooking?

  7. I have never tried recipes for zucchini, such a wonderful tip, thanks for sharing.

  8. Thank you for sharing this recipe, this dish caught my eye I have included it in my June Recipe Roundup at This American Bite.

  9. Thanks for all the nice feedback everyone, and I love the idea of serving this with garlic yogurt like Luana suggested!

  10. More important than perfect, it looks really good!

    A great sauce for that would be some Greek yogurt that has one pressed or finely chopped garlic clove mixed in it, really good and very easy. I have a Turkish friend who serves this; it's not as complicated as tzatziki, and ready in a minute.

  11. Kalyn, There's nothing better than grilled veggies in the summertime. Love it!

  12. Those are perfectly grilled zucchini slices! I happened to love zucchini in any form, but grilled zucchinis are delicious.

  13. Grilled Zucchini is one of those great tastes of summer — to us, at least. I'll do up extra to serve at room temp with a little Smoked Provalone and fresh tomatoes as a sandwich. Probably not very SB friendly, but so worth it!

    Since there's no fear of cross contamination, if you put the left over marinade in the 'fridge, it's a nice dressing on the sandwich. Oh yum!

  14. Made these this evening, didn't have italian dressing but used a mrs dash italian garlic marinade. Delicious, Thanks!

  15. This is such a wonderful tip and the pics look yummy! Thanks for sharing!

    – DV

  16. Elizabeth, so glad you liked it! I like the idea of "fries."

  17. Just made this tonight and it was great even though it only sat for about 15-20 min in the marinade. I had long skinny zukes and summer squash so I cut them lenghwise into spears. My son called them zucchini and summer squash "fries." We loved them. Thanks!!

  18. Brittany, hope you enjoy it!

  19. I have been searching for recipes for zucchinu and came across your site. We are trying this for dinner tonight (it is currently marinating in the fridge)! 🙂 Thanks so much for sharing. I will be checking back often!


  20. Lauren, thanks! So glad you liked it.

  21. We made this recipe with zucchini and squash last night for dinner, and it was great. I had been looking for a simple marinade that didn't involve balsamic vinegar and this was perfect! I didn't have time to let them marinate for the full four hours, but it was delicious anyway. Next time I'll start earlier 🙂 Thanks for posting!

  22. Stellula, hope you enjoy it.

  23. This is perfect. I ended up with a HUGE zucchini from a co-worker, and muffins and casseroles have made a dent in the zucchini, but grilled zucchini will finish it off. Thanks for sharing!

  24. Lovin' Life, glad you liked it!

  25. These look delicious!! I shared your recipe on my blog as too. Thank you!!!

  26. Anonymous, these were round "8-Ball" zucchini, so there is no "long way" to cut them!

  27. My brother cooks zucchini on the grill and it's terrific! He slices it the long way, though, so you end up with these long thick slabs. Not so much cutting up into little pieces (for the cook, anyway).

  28. Have never tried grilled zucchini – this was so easy and so very good. Thank you for posting.

  29. This zucchini was so yummy- we were fighting over the last piece! (Obviously, I need to make more next time. LOL) Thank you so much for sharing the recipe to this summertime treat. It is a new fav at our house. YUM

  30. Anonymous, you're so welcome. Glad you liked it!

  31. Thank you so…much for this recipe for grilled zucchini. We absolutely loved it! The zucchini were good in the dressing before grilling too!! Thanks again!

  32. This is exactly how I grill zucchini too! Yum!

  33. Grilled zucchini..that really sounds good!

  34. I just discovered that I love grilled summer squashes (at a restaurant) and we just picked our first yellow summer squash. Thanks for your VERY timely post! And have a fabulous time at Blogher!

  35. Have a great time at Blogher Kalyn. I’m looking forward to hearing all about it when you return.

  36. Have a great time at Blogher!
    We sometimes like to use Italian dressing as the main ingredient in marinating london broil (for grilling).
    and Kalyn, did you get my e-mail about my WHB submission a few days ago (yes, I sent it a bit early this week)?

  37. Have fun at Blogher–I’m looking forward to hearing about it. And the zucchini does look perfect.
