If you’ve been wondering how to cook zucchini and squash on Blackstone, you’re in the right place.
 
It’s a simple process that takes just a few minutes once your griddle is hot.
 
And the best part is you can season them a hundred different ways depending on what you’re in the mood for.
 
In this post, we’ll walk through how to cook zucchini and squash on Blackstone, from prep to plating, so you can nail it every time.
 
Let’s fire up that griddle.
 

How to Cook Zucchini and Squash on Blackstone

Learning how to cook zucchini and squash on Blackstone really comes down to three things: high heat, the right oil, and not crowding the griddle.
 
When you cook zucchini and squash on Blackstone, the flat-top gets screaming hot and gives you that beautiful char in minutes.
 
Here’s the step-by-step process so you know exactly how to cook zucchini and squash on Blackstone without them turning to mush.
 

1. Preheat Your Blackstone to Medium-High Heat

The first step in how to cook zucchini and squash on Blackstone is getting the surface properly heated.
 
Turn your griddle on medium-high and let it preheat for about 10 minutes.
 
You want it hot enough that a drop of water sizzles the second it hits the surface.
 
If the griddle isn’t hot enough, your zucchini and squash will steam instead of sear.
 
And nobody wants soggy squash.
 

2. Slice Zucchini and Squash Evenly

Cut your zucchini and squash into half-inch rounds or quarter-inch planks.
 
The key is keeping the slices uniform so they cook at the same rate.
 
If some pieces are thick and others are paper-thin, the thin ones will burn before the thick ones soften.
 
Pat the slices dry with a paper towel because moisture is the enemy of a good sear.
 

3. Oil and Season Generously

Toss your zucchini and squash in a bowl with a couple tablespoons of avocado oil or another high-smoke-point oil.
 
Then season with salt, black pepper, garlic powder, and onion powder.
 
You can also add smoked paprika, Italian seasoning, or red pepper flakes for a little kick.
 
Coating the zucchini and squash before they hit the griddle helps the seasoning stick and the edges caramelize.
 

4. Lay Them Flat and Don’t Touch Them

Place the zucchini and squash slices flat on the hot Blackstone in a single layer.
 
Leave a little space between each piece so they sear instead of steam.
 
Now here’s the hard part: don’t touch them for 2 to 3 minutes.
 
Let the griddle do its job and build that golden crust.
 

5. Flip and Finish

After 2 to 3 minutes, flip each slice with a spatula.
 
Cook for another 2 minutes until both sides are golden brown and the centers are tender.
 
If you want them softer, give them an extra minute.
 
If you like a bit of crunch, pull them off right after the flip.
 

Best Seasonings and Flavor Combinations for Zucchini and Squash on Blackstone

Once you’ve mastered how to cook zucchini and squash on Blackstone, the fun part is playing with flavors.
 
Here are some winning combos to try.
 

1. Garlic Butter and Parmesan

Melt butter on the griddle, toss in minced garlic, then add your cooked zucchini and squash.
 
Finish with a shower of grated parmesan and fresh parsley.
 
It’s rich, savory, and always a hit.
 

2. Lemon Herb Medley

Squeeze fresh lemon juice over the zucchini and squash right after they come off the griddle.
 
Then sprinkle with chopped basil, oregano, and a pinch of sea salt.
 
The bright acidity balances the smoky char beautifully.
 

3. Smoky Southwest Style

Season with cumin, chili powder, smoked paprika, and a squeeze of lime.
 
Top with crumbled cotija cheese and cilantro for a taco-night side that disappears fast.
 

4. Balsamic Glaze Finish

Drizzle a balsamic reduction over the cooked zucchini and squash just before serving.
 
The sweet-tangy glaze pairs perfectly with the caramelized edges.
 
Add toasted pine nuts for a little crunch.
 

Common Mistakes to Avoid When Cooking Zucchini and Squash on Blackstone

Knowing how to cook zucchini and squash on Blackstone also means knowing what not to do.
 
Avoid these common mistakes and your griddle veggies will turn out perfect every time.
 

1. Overcrowding the Griddle

If you pile too many zucchini and squash slices on the Blackstone at once, they’ll release moisture and steam.
 
Cook in batches if you’re feeding a crowd.
 
It takes a few extra minutes but the results are worth it.
 

2. Skipping the Preheat

A cold griddle is the fastest way to ruin zucchini and squash.
 
Always give your Blackstone a full 10 minutes to heat up before adding anything.
 

3. Cutting Them Too Thin

Paper-thin slices turn to mush on a hot griddle.
 
Aim for half-inch rounds so the zucchini and squash hold their shape and texture.
 

4. Not Drying the Slices

Water is the enemy of browning.
 
Pat your zucchini and squash dry before oiling and seasonings so they sear instead of stew.
