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.

  1. Joanne, I agree! It's not a showy dish, but they're delicious!

  2. I love seeing posts like these because they remind me how delicious simply grilled veggies are! No need for fuss!

  3. Shirley for camping I take the veggies already cut up in the ziploc bag and then pour the dressing on the morning of the day I want to cook them. You must get a pan like this; you'll love it!

    Cmanwarren, glad I an inspiring you to put veggies on the menu!

  4. Great suggestions! Grilled vegetables will be on our holiday menu for this weekend!

  5. Anything that says "World's Easiest" I'm game for, Kalyn, and roasted veggies are my favorite. Even hubby can't resist them when roasted. I'm definitely getting one of these grill pans. We can use it all the time, but it will come in handy when we go camping the most as that's where most of our grilling takes place. 😉 Oh, and I agree on using Italian dressing. It's also great for meat marinades. One can find one a ready-made on they like or mix up a few ingredients on their own to have the same effect. Really great post, Kalyn–thanks! 🙂


  6. Elizabeth, I must try green beans as well! I agree, these pans that cook on the grill are just the greatest!

  7. I adore vegetables done this way!! (We like to add a few parboiled potatoes and button mushrooms then garnish with as many fresh herbs as we can find.)

    Like you, we have two barbecue woks. Neither is that lovely copper colour though; they're both black enamel. But they're the best utensils, aren't they?

    We love green beans cooked in the barbecue wok. And asparagus with baby onions is pretty brilliant as well.

    But I'd never thought of cooking broccoli in the barbecue wok. Good idea, Lydia!

  8. Lydia, grilled broccoli! I MUST try that soon.

  9. I also use Newman's Own dressing for marinating veggies (and chicken breasts) for the grill, though I'm partial to the light balsamic variety. Lately I've been trying to broaden my veggie grilling horizons, by grilling things I haven't done often before (broccoli, potatoes, eggplant), because everything seems to taste better on the grill.

  10. Not sure why, but I've never grilled brussels sprouts. Love that idea, sounds fantastic!

  11. I never thought about using Italian dressing! Lately I've been on a brussel sprout kick. They taste so delicious when grilled or roasted! I usually just use some non-stick spray on them and season it up a bit before grilling! I love them charred too…gives them a nuttiness! I will have to try the Italian dressing trick! Sounds yummy!

  12. Cindy, agreed!

    Susie, I think red peppers really get a lot sweeter when they're grilled. Lucky you, grilling all year!

  13. Thanks for the tip about the Italian dressing. We grill veggies all the time. Our favorite is grilled red bell peppers. When we serve them to guests, I'm amazed by the number of people who say they don't like red peppers but love them when they are grilled.

  14. We do exactly the same thing! Exactly!! It's amazing what a little fire can do for a veggie. Yum. –Cindy

  15. CJ, sounds like a lot of good grilled veggies at your house. And hooray that it's finally grilling weather!

  16. I have a grill basket and I LOVE it! It makes vegetables taste incredible.
    Sometimes I'll finish the dish with fresh herbs, chopped kalamata olves or a little feta cheese, but that's not necessary. The vegetables stand alone in flavor. Good warm or room temp. Fantastic as an antipasto.

    Hooray that grilling season is in full swing.

  17. Barbara, this is SO easy and still delish. (My kind of recipe!)

    Nancy, asparagus is good with everything, don't you agree? I'll have to try portobello mushrooms. I like regular mushrooms cooked separately because they seem to cook more quickly than other veggies.

    Anon- Wow, what a nice comment. You are so welcome, and it makes me very happy that your kids are enjoying the food!

  18. Kalyn you are the BEST!!! You are so kind to share all your wonderful recipes and techniques
    ! I use your recipes and suggestions so much that my kids ask me "Is this one of Kalyn's recipes". We never met you but you are a very important part of our family!! Thanks so, so much… :0)

  19. Asparagus would also be great with any of the combos you list. Bermuda onions also work. And portabello (?) mushrooms are great. I use the leftover atop a luncheon salad the next day, or chopped smaller & put in a great South Beach omelet!

  20. I'll have to try the Newman's Own dressing. It doesn't get much easier than this. I need to step it up.
