Grilled zucchini is a simple, nutritious summer side dish that goes with just about anything! You’ll love this version with lemon and Italian herbs.

Is it even summer if you’re not throwing vegetables on the grill for a quick and easy summer side dish?

Zucchini makes an appearance on our table at least once a week this time of year. I love the texture that grilled zucchini has and its neutral flavor means it goes well with everything from chicken to burgers.

Zucchini is mild, which means its a blank slate for whatever seasonings you’re in the mood for. You can use lemon, garlic, and Italian seasonings like I do in this recipe, or even just toss it in oil and balsamic vinegar. Zucchini acts like a sponge, so it will soak all of that flavor right up!

Depending on the seasonings you use, this side dish can be low carb, gluten-free, whole 30, paleo, and/or dairy free. (And yes, you can totally make this recipe with yellow squash, too!)

How to grill zucchini, step by step:

Tips for the best grilled zucchini:

  • Chose small, firm zucchini. Big zucchini have lots of seeds and can be kind of mushy inside — no one wants that!
  • Cut it evenly so it all cooks at the same rate. For grilled zucchini, I like to cut it into wedges. This way the pieces are big enough not to fall through the grates and there’s plenty of surface area to get nice and charred.
  • Don’t worry about peeling the zucchini – the skins are tender and taste great! It also helps give the zucchini spears some structure.
  • If you want, you can salt the zucchini before marinating it. This isn’t necessary, but it will draw some moisture out, resulting in a firmer vegetable. After cutting the zucchini, sprinkle it with salt and set it in a colander in the sink. After about 10 minutes, wipe the salt (and any accumulated moisture) off with a towel.
  • Make sure your grill is clean and well oiled to prevent the zucchini from stick to the grated. A grill basket is also helpful here
  • If you don’t have a grill, or if the weather is bad, you can use a grill pan inside or follow this method for broiled zucchini.
