What is a zucchini?

Zucchini is a summer squash that is long and green on the outside and pale yellow on the inside. It kind of looks like a cucumber.

Both the outer skin and small internal seeds are edible, so it’s a quick and easy vegetable to grill.

Zucchini are very similar to yellow squash, and they’re often found next to each other in the produce section.

Although it’s a summer squash, it’s not just available in summer months. You can find it year round.

How To Grill 20 Vegetables


When grilling vegetables for the first time, I recommend starting with olive oil, salt and pepper. Most of the time, that’s all vegetables really need.

  • Zucchini
  • Olive Oil
  • Kosher Salt
  • Coarse Ground Black Pepper

Because zucchini is so mild, it also goes well with more adventurous flavors like balsamic vinegar, Italian seasoning and fresh herbs. You can easily match the seasonings to the rest of your meal.

How to grill zucchini

This is a really fast cook. You can season the zucchini a couple hours in advance and store it on a pan on the counter or in the refrigerator until right before you’re ready to fix dinner.

  1. STEP ONE: Heat your grill to medium-high heat with a direct heat zone. This is about 375-400F degrees. If you’re cooking these inside, heat your indoor grill pan on the stove over medium-high heat.
  1. STEP TWO: It’s best to cut the zucchini before grilling it. You have a few options. You can make zucchini spears. You can simply make 1/4-inch slices. Or, you can slice the zucchini vertically into long strips.

When slicing it vertically, I like to remove the ends, so the zucchini is flat and stable when I stand it up on its end. Then, you can either slice long vertical strips or slice the zucchini in half and then slice it into vertical strips.

A small zucchini will usually result in 4 vertical slices. With a large zucchini, you can get 5.

If your pieces are cut too thin, you may want to consider using a grill basket so they don’t fall between the grill grates.

  1. STEP THREE: Place the cut zucchini in a single layer onto a sheet pan or in a large bowl. Drizzle the pieces with olive oil. Then, sprinkle all sides with salt and pepper.
  1. STEP FOUR: Place zucchini on the hot grates and cook for about 7 minutes, until grill marks start to form.

  1. STEP FIVE: Flip the zucchini and continue cooking for another 5-8 minutes. The cook time will vary, depending on how thick your slices are. You want to create more grill marks and the zucchini should be soft and tender.

How to serve grilled zucchini

Remove the zucchini from the grill and place it on a platter.

At this point, you could garnish it with fresh herbs, a drizzle of balsamic vinegar or even a sprinkling of grated parmesan cheese.


Grilled zucchini can be stored in an airtight container in the refrigerator for up to a week. Simply reheat it in the microwave.

While you can freeze grilled zucchini, the texture will lose some integrity and it can become mushy.

Grilled Zucchini

Grilled zucchini is one of my favorite side dishes. The squash holds up so well to the grill and can be served hot or cold.
Prep Time: 5 minutes
Cook Time: 15 minutes
Total Time: 20 minutes
Servings: 4


  • 2 zucchini squashes
  • 1 tbsp olive oil
  • 1 tsp kosher salt
  • 1 tsp coarse ground black pepper


  • Heat the grill to medium-high (375-400F degrees).
  • Cut zucchini into spears or 1/4-inch thick slices.
  • Drizzle the slices with olive oil and season all over with salt and pepper.
  • Grill cut side down for 7 minutes, until you get nice grill marks.
  • Flip and grill for about 8 more minutes.


I love zucchini with salt and pepper, but you can also add your favorite seasonings. Garlic powder, onion powder and lemon zest are nice touches. 
If your slices are thinner, they will cook in less time. 
If your slices are thicker, they will need a little more time. 
The main thing to look for is nice grill marks. You also want the zucchini to still be a little firm inside.
