Grilling season has arrived, and I couldn’t be happier about it! A few years ago I shared this ultra-simple recipe for World’s Easiest Grilled Vegetables, and this has become the easy grilled vegetable side dish I make all summer long. And I’ve already picked some zucchini from my garden and made it this year with fresh garden zucchini, which only makes it better!

Marinating the veggies in a purchased vinaigrette is the simple trick that makes these vegetables a wow, and I think the choice of dressing is pretty important. If you’re a low-carb eater or someone who’s trying to avoid sugar, be sure to choose a dressing with not more than 2 grams of sugar per serving. That won’t be hard to find, but you also need to choose a dressing with oil as the first ingredient. I prefer dressing that’s more oily than creamy when I’m using it as a marinade; I use Newman’s Own Original Recipe Olive Oil and Vinegar Dressing for this recipe, which is one reason it’s always in my fridge.

I’m featuring this recipe for Friday Favorites today to remind you about it, and if you’re trying to eat plenty of vegetables I hope you’ll enjoy this easy recipe for grilled vegetables as much as I have! And check the recipe for other vegetables combinations you can cook using this method.

I use a Grill Pan for Grill Vegetables:

I cook these easy grilled vegetables in a grilling pan with holes (affiliate link) that sits on top of the grill grates. There are endless variations for vegetables you can cook in a pan like this, but most often I use this combination of zucchini, sweet onions, and red bell pepper. You want to cut the vegetables in same-size pieces, not quite 2 inches in size.

How to Make World’s Easiest Grilled Vegetables:

(Scroll down for complete recipe including nutritional information.)

  1. Cut up whatever veggies you’re choosing into same-size pieces.
  2. Put the cut-up veggies into a small Zip-loc bag (or a plastic container with a snap-tight lid) and pour over just enough Italian salad dressing to coat the veggies, then let them marinate in the fridge for 4-6 hours (or longer) before you cook them. I always use Newman’s Own Original Recipe Olive Oil and Vinegar Dressing (affiliate link).
  3. Be sure to drain the vegetables before you dump them into the grill pan or the oil in the dressing will flame up on the grill.
  4. Have your grill pre-heated to medium-high before you start to cook the vegetables, with the grill pan sitting on the grill grates.
  5. Then put veggies into the hot pan and spread them around so as many as possible are touching the surface of the pan.
  6. Start to cook the veggies with the lid closed on the grill.
  7. I give my veggies a stir about every 5 minutes, and cook them 15-20 minutes, depending on what type of vegetables I’m using.
  8. I like it when these easy grilled vegetables get a little charred, but you might prefer yours a little less well-done.
  9. Season with a little salt and fresh-ground black pepper and enjoy!

Other Vegetable Combinations I like for Grilling:

  • Zucchini, Yellow Squash, Sweet Onions
  • Sugar Snap Peas, Red Bell Pepper, Sweet Onions
  • Sugar Snap Peas, Par-boiled Carrots, Sweet Onion (boil the carrots for 2-3 minutes and drain before you marinate)
  • Sweet Potato, Zucchini, Sweet Onion (marinate sweet potato separately and cook it about 5 minutes before adding other vegetables to the pan)
  • Asparagus, Red Bell Pepper, Sweet Onion (cut asparagus into fairly short pieces, cut on the diagonal)
  • Eggplant, Zucchini, Red Bell Pepper
  • Eggplant, Red Bell Pepper, Sweet Onion

World’s Easiest Grilled Vegetables

Yield 4 servings
Prep Time 10 minutes
Cook Time 20 minutes
Total Time 30 minutes

These are the ultra-easy grilled vegetables I make over and over all summer long.


  • 2 medium zucchinis
  • 1 large sweet onion
  • 1 large red bell pepper
  • 1/2 cup Italian Salad Dressing (see notes)
  • pinch of dried herbs such as thyme, oregano, ground fennel, or dried basil (optional; I rarely add herbs)
  • salt and fresh ground black pepper to season vegetables after grilling


  1. Cut ends off the zucchini, then cut in half lengthwise and cut into slices not quite 2 inches thick.
  2. Peel onion, cut off ends, cut in half, then break apart into individual layers and cut each one into same-size pieces.
  3. Cut red bell pepper in half, cut out seeds and stem, and cut into pieces the same size as the onion and zucchini.
  4. Put the vegetables into Ziploc bag or plastic container with tight-fitting lid, choosing the smallest size you can to fit all the vegetables so they get well coated with the marinade.
  5. Pour in enough dressing to coat the vegetables, about 1/2 cup. Add dried herbs if desired, then close the bag or container and marinate in the fridge for 4-6 hours (or all day is fine if you’re at work.)
  6. When you’re ready to cook vegetables, put the grill pan on the grill grate and preheat grill (and pan) to medium-high heat. (You can only hold your hand there for a few seconds at that heat.)
  7. Drain vegetables into a colander placed in the sink and let dressing drain off while you preheat the grill. (This is very important to prevent flare-ups when you add the vegetables to the grill pan.)
  8. When grill and pan are hot, pour in the vegetables and spread them around so as many as possible are touching the surface of the pan.
  9. Cook with grill lid closed, stirring the vegetables every 5 minutes or so to insure that they get lightly browned on all sides.
  10. Cook about 15-20 minutes, or until vegetables are cooked but still slightly crisp and starting to char on the edges. (I don’t mind if mine get a bit charred, but keep an eye on them if you’d like them less browned.)
  11. Serve hot, with salt and fresh ground pepper to season.


I like Newman's Own Classic Oil and Vinegar Dressing (affiliate link)for marinating the vegetables; be sure to use a low-sugar dressing with oil as the first ingredient.

If you have leftover grilled vegetables, they’re best reheated for a few minutes in a very hot frying pan.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
These easy grilled vegetables vegetables are a wonderful side dish for the South Beach Diet or other low-carb eating plans.

  8. wow!!! I was hoping to find a recipe that sounds equally easy…as it is tasty. I look forward to using a new grill basket tomorrow cooking lunch for my mom! Thank you!!!

  9. Grilled Vegetables are so tasty! I bought a vegetable grill pan a year ago and have not used it yet. I have decided to be the chief vegetable griller. Can't wait until my husband tastes these delicious recipies. Thanks, Kalyn.

    • Wanda you are going to love the vegetable basket for the grill! I have a couple of different sizes and use them all!

  10. Kalyn, as far as I know, if you eat a lot of eggplant will make the body soreness. Is there a suitable recipe in this case, or just for a eggplant like me lol

    • I mean eggplant fan, like me

    • Jeanette, I am not completely sure what you mean? But if you're wondering if you can cook eggplant this same way, the answer is yes. There are some other grilled eggplant recipes on the blog too; just enter "grilled eggplant" into the search bar. Let me know if that wasn't what you meant.

    • Kalyn, Thanks so much for your feedback and it's sorry to get you confused. Yes, I could find some other great recipes with "grilled eggplant" search. However, I am asking that, as I checked around and learnt that our bodies will be pain if we eat a lot of eggplant. Please correct me if I am wrong !

    • Jeanette, I've never heard of anything like that. I did a quick search in google and didn't find anything. In general I think a varied diet is healthiest, but I think you could eat eggplant several times a week before I would worry at all.

    • Kalyn,
      Thanks so much for your feedback and well noted. I think enough and right eating in this case is a best choice

  11. Hi Kayln,
    I like your work.
    We love grilled veg done in a bbq wok. We have two, a round one like yours (but not copper,) and a square SS one (very handy for gas grills, such as portables, with very low lids.) Customized dressings are easy to concoct in a plastic bag: oil; powdered garlic; something thick to help coatings stick (BBQ sauce, HP Worchestershire-type sauce, oyster sauce, thick teriyaki sauce, etc.); and a source of salt (fish sauce, soya sauce.) Many ways to go. Shake coarsely cut peppers, onions, broccoli, squash, or other firm veg in a bag with dressing. After these have been cooked for a while (3-4 stirs, 15 min or so) shake tomato wedges and mushrooms in the same bag and add to the wok, and cook for a few minutes more. The tomatoes add some juiciness.
    Serve warm on a bed of spinach, with or without some sort of tomato-based salad dressing. Yum!

    • Rod it sounds like you have done a lot of experimenting with grilled veggies! I wouldn't add a sweet sauce like barbecue sauce or teriyaki sauce (since I am trying to avoid extra carbs) but some of those other ideas sound great!

  12. Hi Kalyn,
    I want to let you know the link to Newmans does not work since they have reworked their site. You can still view the dressing but you just have to go to the"home page" first and then follow your nose to the dressing. I am working on eliminating soy from my intake so have become an avid reader of labels. It may or may not contain soy and or canola. I have a pretty good homemade version of this using both extra version and light olive oils and champagne vinegar. I got it initially from an American Heart Association cookbook, which had the blend of herbs I use. I don't even measure. It has nutmeg and summer savory in addition to the usual suspects. We love it. My veggies are marinating in it right now but it's very stormy so I may wrap them in foil and pop in the oven.

  13. This is how I've cooked veggies for years! I also love to season with oil and a packet of dry Good Seasons Italian in order to eliminate the chemicals often found in bottled dressings. And in the dead of winter, I'll just dump it them on a biscuit pan and roast in the oven for 30 min at 350 or so. Yum!
