Cooking zucchini and squash on a Blackstone griddle is one of the easiest, fastest ways to get a healthy side dish on the table.
 
In this post, we’ll break down exact cook times for zucchini and squash on Blackstone, plus prep tips, temperature settings, and seasoning ideas.
 
Let’s fire up that griddle.
 

How Long to Cook Zucchini and Squash on Blackstone

The short answer is: cook zucchini and squash on Blackstone for about 4 to 6 minutes per side over medium-high heat.
 
But that range shifts depending on the thickness of your slices and the temperature of your griddle.
 
Here’s how to nail the timing every single time.
 

1. Thin Slices (1/4 Inch)

If you slice your zucchini and squash into thin coins or planks around a quarter inch thick, they cook fast.
 
Expect them to take roughly 3 to 4 minutes per side on a griddle set to medium-high (about 375°F to 400°F).
 
Thin slices soak up seasoning beautifully and get a nice sear, but they can turn mushy if you walk away.
 
Stay close and flip once you see the edges start to soften and brown.
 

2. Thick PlanKS or Half-Moons (1/2 Inch)

Thicker cuts need more time and a slightly lower heat so the outside doesn’t burn before the inside cooks through.
 
For half-inch planks or half-moons, cook zucchini and squash on Blackstone for about 5 to 6 minutes per side.
 
That’s roughly 10 to 12 minutes total.
 
You’ll know they’re done when a fork slides in easily but they still hold their shape.
 

3. Whole or Halved Squash

Small zucchini or yellow squash halved lengthwise take the longest.
 
Place them cut-side down first and give them 6 to 8 minutes, then flip and cook another 4 to 5 minutes.
 
When you cook zucchini and squash on Blackstone this way, you get those deep, caramelized grill marks that make them look like they came off a fancy restaurant grill.
 
Total time lands right around 10 to 13 minutes.
 

How to Cook Zucchini and Squash on Blackstone Perfectly

Timing is only half the battle.
 
How you prep and season your zucchini and squash on Blackstone matters just as much as the clock.
 
Here’s how to get it right.
 

1. Preheat Your Griddle Properly

Set your Blackstone to medium-high and let it preheat for at least 10 minutes.
 
A hot, even surface is the difference between a sear and a sad, steaming pile of squash.
 
Sprinkle a few drops of water on the surface — if they sizzle and dance, you’re ready.
 

2. Dry Your Veggies Before Cooking

Zucchini and squash are mostly water, and moisture is the enemy of browning.
 
Pat your sliced zucchini and squash dry with paper towels before they hit the griddle.
 
This one step keeps them from turning soggy when you cook zucchini and squash on Blackstone.
 

3. Oil Lightly, Don’t Drown

Brush on a thin layer of avocado oil, canola oil, or olive oil.
 
Too much oil causes splattering and steaming rather than searing.
 
A light coat helps the seasoning stick and gives you that golden crust.
 

4. Season Simply and Generously

Salt, black pepper, and garlic powder are the holy trinity here.
 
Add smoked paprika for depth, or Italian seasoning for a herby twist.
 
Season before cooking, then taste and adjust after they come off the griddle.
 

5. Don’t Crowd the Griddle

Spread your zucchini and squash in a single layer with a little space between each piece.
 
Crowding traps steam and ruins the texture.
 
If you’re cooking a big batch, work in rounds and keep finished pieces warm in the oven at 200°F.
 

6. Flip Once, Not Five Times

Resist the urge to keep flipping.
 
Let each side cook undisturbed so those beautiful char marks develop.
 
One flip halfway through is all you need when you cook zucchini and squash on Blackstone.
 

Best Seasonings and Serving Ideas

Once you know how long to cook zucchini and squash on Blackstone, the fun part begins — flavor.
 
Try a squeeze of lemon and a sprinkle of parmesan right after they come off the heat.
 
A drizzle of balsamic glaze adds a sweet, tangy finish.
 
Red pepper flakes bring a little heat if you like things spicy.
 
These griddled veggies pair beautifully with grilled chicken, steak, or fish.
 
You can also toss them into pasta, grain bowls, or a warm salad with feta and herbs.
 

So, How Long to Cook Zucchini and Squash on Blackstone?

How long to cook zucchini and squash on Blackstone comes down to thickness and heat.

Follow these tips and you’ll cook zucchini and squash on Blackstone like a pro every single time.
