In this post, we’ll walk through how to grill green squash step by step, plus some tips on seasoning and avoiding common mistakes.
 
Let’s fire up that grill.
 

How to Grill Green Squash Perfectly Every Time

Grilling green squash comes down to a few simple steps, and once you get them down, you’ll do it on repeat all summer long.
 
Here’s exactly how to grill green squash so it comes out charred on the outside and tender on the inside.
 

1. Pick the Right Green Squash

The best green squash for grilling is firm, heavy for its size, and free of soft spots.
 
Small to medium squash work better than giant ones because they have fewer seeds and firmer flesh.
 
If you’re grilling green squash from your garden, pick them while they’re still young and glossy.
 

2. Slice It Thick Enough to Hold Up

When you grill green squash, cut it into planks or rounds that are about half an inch thick.
 
Too thin and it’ll fall apart on the grates, too thick and the middle stays raw while the outside burns.
 
For long squash like zucchini, slice lengthwise into strips so they’re easier to flip.
 

3. Salt and Rest Before Grilling

Sprinkle your sliced green squash with salt and let it sit for about 15 minutes.
 
This draws out excess moisture, which is the number one reason grilled green squash turns soggy.
 
Pat the slices dry with a paper towel before they hit the grill.
 

4. Coat Lightly in Oil

Brush each piece with olive oil or avocado oil so it doesn’t stick and gets those nice grill marks.
 
Don’t drench it, just a light coating is enough when you grill green squash.
 

5. Preheat the Grill to Medium-High

Your grill should be hot before the squash goes on, around 400 to 450°F.
 
A hot grill sears the surface quickly, which keeps the inside from drying out when you grill green squash.
 

6. Grill 3 to 4 Minutes Per Side

Lay the slices directly on the grates and leave them alone for a few minutes.
 
Flip once, then grill the other side until you see those beautiful char marks.
 
That’s really all there is to how to grill green squash.
 

Best Seasonings and Marinades for Grilled Green Squash

Plain salt and pepper is great, but green squash takes on flavors like a sponge, so have some fun with it.
 
Here are a few winning combos to try the next time you grill green squash.
 

1. Garlic, Lemon, and Herbs

Toss your green squash in olive oil, minced garlic, lemon juice, and fresh thyme or oregano.
 
The citrus brightens everything up and complements the smoky flavor from the grill.
 

2. Balsamic and Honey Glaze

A little balsamic vinegar mixed with honey creates a sweet-tangy glaze that caramelizes beautifully.
 
Brush it on during the last minute of grilling so it doesn’t burn.
 

3. Smoky Paprika and Cumin

If you like a bit of heat, dust your green squash with smoked paprika, cumin, and a pinch of chili powder.
 
It gives grilled green squash a warm, earthy kick that pairs great with grilled meats.
 

4. Parmesan and Black Pepper

Sprinkle freshly grated parmesan over the squash right after it comes off the grill.
 
The cheese melts slightly and clings to every slice, making your grilled green squash feel fancy with almost no effort.
 

Common Mistakes to Avoid When Grilling Green Squash

Even though it’s simple, there are a few traps that can ruin your green squash on the grill.
 
Avoid these and you’ll be golden.
 

1. Skipping the Salting Step

If you skip salting, your green squash releases water onto the grill and steams instead of sears.
 
That’s how you end up with sad, limp slices instead of beautifully charred ones.
 

2. Overcrowding the Grill

Give each piece of green squash its own space so the heat circulates and the edges caramelize.
 
If you crowd them, they’ll steam and never get those grill marks.
 

3. Walking Away Too Long

Green squash cooks fast, so stay close and keep an eye on it.
 
A minute too long and you go from perfectly charred to burnt.
 

4. Dressing It Too Early

Add delicate herbs, lemon juice, or cheese after grilling, not before.
 
High heat dulls fresh flavors and can burn sugary marinades.
 

5. Using Cold Squash Straight From the Fridge

Let your green squash sit at room temperature for a few minutes before grilling.
 
Cold slices cook unevenly, so the outside burns before the inside softens.
 

So, How to Grill Green Squash?

Grilling green squash is easy once you know the basics, and the results are worth it every time.
 
Slice it thick, salt it, oil it lightly, and grill it hot and fast for a few minutes per side.
 
Season it however you like, and serve it while it’s still warm and slightly charred.
 
Now that you know how to grill green squash, you’ve got a go-to side dish for every backyard cookout this season.
