To cut zucchini and squash for grilling, slice them lengthwise into planks or rounds that are about 1/2-inch thick.
This size holds up beautifully on the grill without turning mushy or falling through the grates.
If you’ve ever wondered how to cut zucchini and squash for grilling so they come out perfectly charred and tender, you’re in the right place.
The key is consistent thickness so every piece cooks at the same rate.
In this post, we’ll walk through how to cut zucchini and squash for grilling, the best shapes for different squash varieties, and a few tips to keep them from sticking.
Let’s get grilling.
How to Cut Zucchini and Squash for Grilling
Learning how to cut zucchini and squash for grilling starts with a few simple steps.
Here’s the process broken down:
1. Wash and Trim the Ends
Rinse your zucchini and squash under cool water to remove any dirt.
Pat them dry with a clean towel because excess moisture can cause them to steam instead of char.
Slice off both ends with a sharp knife.
A sharp knife is crucial here because a dull blade will bruise the delicate flesh.
2. Choose Your Cut: Planks, Rounds, or Spears
When you cut zucchini and squash for grilling, you have three main options.
Lengthwise planks are the most popular because they’re easy to flip and give you those lovely grill marks.
Simply stand the zucchini upright and slice it into long strips about 1/2-inch thick.
Rounds work well for smaller squash like pattypan or baby zucchini.
Just lay them flat and cut crosswise into 1/2-inch coins.
Spears are great for larger squash because they’re sturdy and won’t fall apart.
Cut the squash in half lengthwise, then cut each half into wedges.
3. Keep the Thickness Consistent
The secret to perfectly grilled zucchini and squash is uniform thickness.
Aim for 1/2-inch thick pieces across the board.
If the pieces are too thin, they’ll turn to mush on the grill.
If they’re too thick, the outside will burn before the inside cooks through.
So take your time and try to keep every slice the same size.
4. Scoop Out Seeds for Larger Squash
If you’re grilling large zucchini or yellow squash, the center can be watery and seedy.
After slicing lengthwise, use a spoon to gently scrape out the seeds.
This step isn’t mandatory but it helps prevent soggy planks.
Once you cut zucchini and squash for grilling this way, the texture improves dramatically.
Best Squash Varieties for Grilling
Not all squash are created equal when it comes to grilling.
Here are the ones that hold up best:
1. Zucchini
Zucchini is the go-to choice for grilling because of its mild flavor and firm texture.
It absorbs marinades beautifully and cooks quickly.
When you cut zucchini for grilling, you really can’t go wrong with planks or rounds.
2. Yellow Squash
Yellow squash, also called summer squash, is slightly softer than zucchini.
It grills well but benefits from thicker cuts to avoid falling apart.
Cut yellow squash for grilling into 1/2-inch planks and handle them gently.
3. Pattypan Squash
Pattypan squash has a unique flying saucer shape that looks stunning on the grill.
Slice it into rounds or cut it into wedges.
Its dense flesh holds up nicely to high heat.
4. Butternut Squash
Butternut squash is a winter squash that requires a different approach.
Peel it first, then cut it into 1/2-inch planks or cubes.
It takes longer to cook than summer squash, so give it a head start.
Tips for Grilling Zucchini and Squash Perfectly
Knowing how to cut zucchini and squash for grilling is half the battle.
The other half is nailing the grilling technique.
Here are some tips:
1. Brush With Oil, Don’t Drench
Lightly brush each piece with olive oil before grilling.
Too much oil causes flare-ups and greasy squash.
A thin coating is all you need for nice char marks.
2. Preheat the Grill Properly
Make sure your grill is hot before placing the squash on it.
Medium-high heat is ideal, around 400°F to 450°F.
A hot grill sears the surface quickly and prevents sticking.
3. Don’t Move Them Around Too Much
Place the squash on the grill and leave it alone for 3 to 4 minutes.
Let those grill marks develop before flipping.
Flipping too soon tears the flesh and ruins the presentation.
4. Season After Grilling
Salt draws out moisture, so it’s best to season after grilling.
A sprinkle of sea salt, cracked pepper, and a squeeze of lemon is all you need.
Fresh herbs like basil or parsley take it to the next level.
5. Watch the Cook Time
Zucchini and summer squash cook fast, usually 6 to 8 minutes total.
Butternut squash takes longer, around 15 to 20 minutes.
Keep an eye on them so they don’t turn to mush.
So, How to Cut Zucchini and Squash for Grilling?
To cut zucchini and squash for grilling, slice them into 1/2-inch planks, rounds, or spears, keeping the thickness consistent so they cook evenly.
Wash, trim, and scoop out seeds from larger squash to avoid sogginess.
Brush lightly with oil, preheat your grill, and let them sear without fussing.
And remember, how to cut zucchini and squash for grilling is really about giving them a sturdy shape that stands up to the heat.
Follow these steps and you’ll have beautifully charred, tender squash every single time.
Happy grilling.
