How To Cook Zucchini On The Barbecue

To cook zucchini on the barbecue, you want high heat, quick timing, and a little bit of oil so the slices char instead of steam.
 
It’s one of the easiest vegetables to grill, and once you know how to cook zucchini on the barbecue, you’ll be throwing it on the grate all summer long.
 
The key is treating zucchini like a quick-cooking steak rather than a watery vegetable that needs to soften for ages.
 
In this post, we’ll walk through how to cook zucchini on the barbecue, the best ways to prep it, and a few flavor tricks that make it taste amazing.
 
Let’s fire up the grill.
 

How to Cook Zucchini on the Barbecue

Cooking zucchini on the barbecue comes down to three things: heat, surface contact, and seasoning.
 
Get those right, and you’ll have tender, smoky, slightly charred zucchini every single time.
 

1. Choose the Right Zucchini

Small to medium zucchini are best for the barbecue because they have fewer seeds and firmer flesh.
 
Big, watery zucchini tend to turn mushy on the grill, so save those for baking or soups.
 
Look for zucchini that feel heavy for their size and have shiny, unblemished skin.
 

2. Slice Them Thick Enough

If you cut zucchini too thin, they’ll fall apart or slip through the grill grates.
 
Aim for slices about half an inch thick, or cut them lengthwise into planks.
 
Lengthwise planks are actually my favorite way to cook zucchini on the barbecue because they hold up well and get great grill marks.
 

3. Salt Them First

Zucchini are full of water, and salting them pulls some of that moisture out.
 
Sprinkle sliced zucchini with salt and let them sit for about 15 minutes, then pat them dry.
 
This step keeps them from steaming on the grill and helps them char properly.
 

4. Oil and Season

Brush the zucchini with olive oil or avocado oil so they don’t stick to the grates.
 
Season with black pepper, garlic powder, or a sprinkle of Italian herbs.
 
You can also toss them in a simple marinade of olive oil, lemon juice, and minced garlic before they hit the barbecue.
 

5. Preheat the Grill Hot

You want your barbecue at medium-high heat, around 400 to 450°F.
 
A hot grill gives zucchini a quick sear so the outside chars while the inside stays tender.
 
Clean the grates and oil them lightly right before placing the zucchini down.
 

6. Grill Them Fast

Cook zucchini for about 3 to 4 minutes per side, depending on thickness.
 
Don’t move them around too much, let them sit so they develop those nice dark grill lines.
 
Flip once, cook the other side, and pull them off while they’re still slightly firm.
 

7. Finish with a Little Something

Once they’re off the barbecue, finish zucchini with fresh lemon juice, parmesan, or a drizzle of balsamic glaze.
 
A sprinkle of fresh herbs like basil or parsley wakes up the flavor.
 
This is what turns simple grilled zucchini into something people actually fight over.
 

Best Ways to Prep Zucchini for the Barbecue

How you prep zucchini depends on what you’re serving, but a few methods work best on the barbecue.
 

1. Lengthwise Planks

Cut zucchini into long strips about half an inch thick for an easy flip and great presentation.
 
These are perfect as a side dish or layered into a grilled veggie sandwich.
 

2. Round Slices

Round coins cook fast and work well in skewers or foil packets.
 
Just keep them thick enough so they don’t dry out or fall apart.
 

3. Halved Mini Zucchini

Baby zucchini are ideal for the barbecue because they cook evenly in just a few minutes.
 
Halve them, oil them, and grill cut side down for a beautiful char.
 

4. Zucchini Skewers

Thread chunks of zucchini onto skewers with onions, peppers, and cherry tomatoes.
 
This is a fun way to cook zucchini on the barbecue for a crowd.
 

Common Mistakes When Cooking Zucchini on the Barbecue

Even though grilling zucchini is simple, a few mistakes can ruin the texture.
 

1. Slicing Too Thin

Thin slices dry out and turn limp, so always go a bit thicker than you think.
 

2. Skipping the Oil

Without oil, zucchini sticks to the grates and tears apart when you flip it.
 

3. Grilling on Low Heat

Low heat steams zucchini instead of grilling it, and you end up with soggy slices.
 

4. Overcooking

Zucchini cook fast, so stay close to the barbecue and pull them off while they still have some bite.

To cook zucchini on the barbecue, slice them thick, salt and oil them, and grill them hot and fast for a few minutes per side.
