How long do you broil zucchini?
The answer is simple: you broil zucchini for about 5 to 8 minutes per side, depending on the thickness of your slices and how tender or charred you like them.
Broiling zucchini is one of the fastest ways to get a smoky, caramelized veggie side on the table, so if you’ve ever wondered how long do you broil zucchini, you’re in the right place.
The short window matters because zucchini is mostly water.
That means it can go from perfectly crisp-tender to mushy in just a minute or two under high heat, so timing really is everything here.
In this post, we’ll walk through exactly how long to broil zucchini, the best way to prep it, and the little tricks that keep it from turning soggy.
Let’s get to it.
How Long Do You Broil Zucchini?
How long you broil zucchini depends on a few things, but the general rule is 5 to 8 minutes per side.
Here’s how that breaks down based on how you cut it:
1. Sliced Rounds or Spears (½ inch thick)
If you slice your zucchini into ½-inch rounds or spears, broil them for about 5 to 6 minutes per side.
Set your oven rack 6 inches from the heating element and flip them halfway through.
You’ll know they’re done when the edges are golden and the centers are fork-tender but not collapsing.
2. Thin Slices (¼ inch thick)
Thin slices broil fast, so give them just 3 to 4 minutes per side.
These are perfect if you want crispy zucchini chips or a quick topping for salads and grain bowls.
Keep a close eye on them because ¼-inch slices can scorch in seconds.
3. Thick PlanKS or Halves (1 inch thick)
For thicker cuts like planks or halved zucchini, broil for 7 to 8 minutes per side.
These bigger pieces hold up well and stay juicy inside while the surface gets that nice char.
Just make sure they’re evenly coated in oil so they don’t dry out.
4. Whole Small Zucchini
You can even broil whole small zucchini, and those take around 8 to 10 minutes per side.
Pierce them with a fork first so steam can escape and they cook evenly.
So the next time someone asks how long do you broil zucchini, you can tell them it depends on thickness, but 5 to 8 minutes per side covers most cuts.
How to Broil Zucchini So It Turns Out Perfect
Knowing how long to broil zucchini is half the battle, but prep matters just as much.
Follow these steps and you’ll get tender, flavorful zucchini every single time.
1. Slice Evenly
Cut your zucchini into pieces of the same thickness so they finish cooking at the same time.
Uneven slices mean some pieces burn while others stay raw.
2. Pat Them Dry
Zucchini holds a lot of water, and moisture is the enemy of browning.
Pat the slices dry with a paper towel before seasoning.
This one step makes a huge difference in how your broiled zucchini turns out.
3. Toss With Oil and Seasoning
Brush or toss the zucchini with olive oil so every surface gets a light coating.
Then season with salt, pepper, garlic powder, or Italian herbs.
Oil helps the zucchini caramelize instead of steaming under the broiler.
4. Use a Sheet Pan or Broiler-Safe Dish
Arrange the slices in a single layer on a baking sheet or broiler-safe dish.
Don’t overcrowd them, or they’ll steam instead of roast.
5. Preheat the Broiler
Always preheat your broiler for at least 5 minutes before the zucchini goes in.
A hot broiler gives you that quick char while keeping the inside tender.
6. Watch It the Whole Time
Broiling is fast and unforgiving, so stay by the oven.
Since you already know how long do you broil zucchini, set a timer and check a minute early.
Tips and Common Mistakes When Broiling Zucchini
Even with the right timing, a few small mistakes can ruin your broiled zucchini.
Here’s what to avoid and what to do instead.
1. Skipping the Flip
Flipping halfway through is what gives you even browning on both sides.
If you forget, one side will char while the other stays pale and soft.
2. Cutting Too Thin
Slices thinner than ¼ inch tend to burn before they crisp up.
Stick to ½-inch slices if you’re new to broiling zucchini.
3. Overcrowding the Pan
Too many slices on one pan traps steam and stops browning.
Use two pans if you need to, or broil in batches.
4. Adding Cheese Too Early
If you want melted parmesan on top, sprinkle it during the last 1 to 2 minutes.
Any earlier and it’ll burn before the zucchini is done.
5. Forgetting to Salt After, Not Just Before
A light sprinkle of flaky salt right after broiling wakes up the flavor.
It’s a small step that makes your zucchini taste restaurant-quality.
So, How Long Do You Broil Zucchini?
You broil zucchini for about 5 to 8 minutes per side, depending on how thick you slice it.
Thin slices need just 3 to 4 minutes per side, while thick planks can take up to 8 minutes per side.
The key is to preheat your broiler, pat the zucchini dry, coat it in oil, and flip it halfway through.
Now that you know exactly how long do you broil zucchini, you can get that smoky, caramelized side dish on the table in under 15 minutes.
Happy broiling.
