Grilling is an absolute must in the summer. And, while there are many different ways to grill meat, I wanted to share one of our favorite ways to grill up healthy vegetables.

I love making this grilled zucchini recipe in the summer because it is ready, start to finish, in about 20 minutes.

Plus, it’s gluten-free and low carb, so it’s something that everyone on my guest list can enjoy without a problem.

As it gets warmer, I love being able to move my cooking outside onto the grill.

Have you tried our recipe for grilled Hawaiian ham kabobs? Or, how about spicy grilled corn? There are so many easy grilling recipes to try!!

making marinade for grilled vegetables

Should you salt zucchini before cooking? 

Adding salt to your zucchini helps draw out some of the water content, and it adds flavor as well.

But this grilled zucchini recipe uses a marinade, so there is no need to add extra salt to your squash.

Do you have to peel zucchini before grilling? 

If you purchased your zucchini from the grocery store and the skin has been waxed, yes. You will need to peel the skin to remove the wax.

However, if the zucchini hasn’t been waxed, there is no need to peel it.

If you have a very large zucchini, you can peel it if you think that the skin is more bitter.

But, try it first to be sure, because the skin is loaded with flavor, fiber, and nutrients.

What size zucchini should I use for grilling?

Smaller zucchini have a sweeter flavor, so ideally, you don’t want to larger zucchini on the grill. 

I look for medium-sized zucchini that are about 7″ long. But, if your Italian squash are larger or smaller, they will still work for this grilled zucchini recipe.


If you’ll be making zucchini parmesan using extra large zucchini, you will want to remove the seeds before you make this recipe.

What other vegetables are good for grilling? 

If you are all out of zucchini, you can use this same method to make grilled yellow summer squash, eggplant, bell pepper and onion wedges, or even grilled asparagus spears.

If the vegetables are especially small, you may want to grill them on foil instead to avoid them falling through the cracks.

Zucchini Parmesan FAQ

Can I make zucchini on the grill in foil? 

Yes, if you want to make grilled zucchini in foil packets rather than directly on the grates, you can. Simply make a boat out of the foil, then add the spears and the marinade.

Then, very carefully seal the foil and allow zucchini parmesan to cook for the total time. You can open the foil and turn the zucchini over partway through if you like. But, it isn’t necessary to do that to cook it completely.

This is also an easy time-saving hack when it comes time to clean the grill after cooking.

All you need to do is to remove the grilled zucchini from the foil, and there is no extra clean up involved. That means more time to relax and spend with friends rather than inside doing dishes.

Can I make this recipe inside? 

If you don’t have an outside grill, you can easily make this zucchini parmesan recipe on a stovetop grill pan — as long as the grill you use has ridges on it.

Something similar to a George Foreman indoor grill should work perfectly.

What spices pair well with this easy side dish?

That all just depends on what you want for your own personal consumption. I love topping it with parmesan cheese, but you can easily add garlic powder, black pepper, red pepper flakes, fresh basil, onion powder, fresh garlic or fresh herbs, or anything else that you want. 

The great thing about making this easy recipe is that you can make it any way that you want. 

Can I make this in the oven?

Sure! If you want to cook this indoors, you can add the zucchini spears to a baking sheet in a single layer. Just know that you won’t have grill marks on them, but you will still be able to eat them in your favorite way. 

You can also slice them in zucchini rounds and cook them on a sheet pan as well. I sprinkle a bit of kosher salt on them and sometimes even add finely grated Parmesan cheese to my baked zucchini. Add a spice mix to the whole batch to enhance the flavor.
