Grilled zucchini is an easy and delicious way to use up those garden zucchini. Learn how to grill zucchini perfectly with this simple tutorial.

Why You Need to Make Zucchini on the Grill
While we love baked zucchini and air fryer zucchini, there is something about making zucchini on the grill that is full circle.
Zucchini is such a wonderful summer veggie to harvest and cooking it on the grill will allow you to get a hint of char while cooking it perfectly.
In this post, we’ll teach you everything you need to know about slicing, seasoning, and grilling zucchini perfectly every time.

Zucchini season May-August and this is prime time for either buying zucchini from the grocery store or growing it in your own garden (depending on where you live).
We recommend buying medium-sized zucchini. They should be firm to touch and without any bruises.
Now it’s time to slice your zucchini for grilling. There are many different shapes and sizes you can choose, but just make sure you slice them all the same way so that they cook evenly. Here are some ideas:
- Long strips (how we did it!)
- Spears
- Coins
You can keep things super simple flavor-wise with salt and pepper. But you can also get creative with either storebought or homemade seasonings. Here are some ideas:
- Homemade taco seasoning
- Italian seasoning
- Everything bagel seasoning
- Ranch seasoning
- Homemade cajun seasoning
Next, place each zucchini half onto the tin foil and grill for around 10 minutes, flipping every 4 minutes. Remove the zucchini from the grill once you start to see char marks.
Note: you may need to cook your zucchini for more or less time depending on how to sliced it.
Ways to Use Leftover Grilled Zucchini
Don’t let any zucchini go to waste! Here are some ideas for your leftovers:
- Garden Veggie Hash
- Summer Squash Pasta
- Taco Zucchini Boats
- Stuffed Zucchini

Sometimes zucchini have a ton of seeds and water content. That may sometimes cause grilled zucchini to become mushy. If you do suspect that there are too many seeds in your zucchini halves, use a spoon to scoop them out gently.
You want to get your zucchini nice and grilled up. That may mean grill marks or just golden brown vegetables. We love the flavor that olive oil gives zucchini, but feel free to use whatever oil you would like!
The worse thing you can do is overcook your zucchini and create a mushy mess! If you are going to eat your zucchini immediately, then we recommend grilling it for no more than 10-12 minutes.
However, if you are planning to use the zucchini in another recipe like pasta or for a side dish that you are going to reheat, undercook the zucchini by grilling them for only 8-9 minutes.
Grilled zucchini would be delicious chopped up and tossed into pasta or even makes a great side dish for any meal. Serve this grilled zucchini with any of the recipes below.
