You can broil zucchini in the oven in about 5 to 10 minutes per side, depending on the thickness of your slices and how hot your broiler runs.
That’s the short answer, but there’s a little more to it if you want perfectly tender zucchini with those gorgeous charred edges instead of soggy, mushy slices.
If you’ve been wondering how long to broil zucchini in oven so it comes out just right, you’re in the right place.
In this post, we’ll walk through exactly how long to broil zucchini, how to prep it, and the little tricks that make a big difference.
Let’s get right into it.
How Long to Broil Zucchini in Oven
The answer to how long to broil zucchini in oven really comes down to a few key factors.
Most recipes call for broiling zucchini for about 5 to 7 minutes per side.
That said, thin slices might be done in as little as 3 to 4 minutes per side, while thicker planks or halves can take closer to 8 to 10 minutes per side.
Here’s what actually determines the timing when you broil zucchini in the oven:
1. The Thickness of Your Zucchini
Thin rounds, about ¼ inch thick, will broil zucchini fast.
They can go from perfectly crisp to burnt in under a minute, so keep an eye on them.
Thicker slices, around ½ inch, need closer to 5 to 7 minutes per side.
And if you’re broiling zucchini halves or spears, plan for 8 to 10 minutes per side.
The thicker the zucchini, the longer it takes to broil in the oven.
2. Your Broiler’s Heat Level
Not all broilers are created equal.
Some ovens run blazing hot at 550°F, while others hover closer to 500°F.
A hotter broiler means you’ll broil zucchini in less time, sometimes just 3 to 4 minutes per side.
A gentler broiler might take the full 8 to 10 minutes.
This is why you should always check your zucchini at the halfway mark instead of trusting the clock blindly.
3. The Distance From the Heating Element
The rack position matters more than most people realize.
If you place your baking sheet 4 to 6 inches below the broiler, zucchini will cook evenly and develop nice char without burning.
Move it closer, and you’ll broil zucchini faster but risk a burnt exterior with a raw center.
Move it farther away, and you’ll need extra time to broil zucchini properly.
4. How You Prep the Zucchini
Patting your zucchini dry before broiling helps a lot.
Excess moisture steams the zucchini instead of roasting it, which slows everything down.
A light coat of oil also helps the zucchini broil evenly and brown beautifully.
So the drier and better-oiled your zucchini, the quicker and more evenly it will broil in the oven.
How to Broil Zucchini in the Oven Step by Step
Now that you know how long to broil zucchini in oven, let’s talk about the actual process.
Here’s a simple method that works every time:
1. Preheat Your Broiler
Turn your oven to broil and let it preheat for at least 5 to 10 minutes.
A properly preheated broiler is the secret to getting that nice char when you broil zucchini.
2. Slice and Season the Zucchini
Cut your zucchini into rounds, planks, or halves, depending on what you’re making.
Toss them with olive oil, salt, pepper, and any herbs or spices you love.
3. Arrange on a Baking Sheet
Lay the zucchini in a single layer on a baking sheet.
Don’t overcrowd them, or they’ll steam instead of broil.
4. Broil Zucchini for 5 to 7 Minutes Per Side
Slide the sheet onto the rack and broil zucchini for about 5 to 7 minutes.
Flip each piece and broil zucchini for another 5 to 7 minutes until tender and charred.
5. Watch Closely Near the End
The last minute or two is when zucchini can go from perfect to burnt.
Stay by the oven and pull them out the moment they look right.
Tips for Perfectly Broiled Zucchini
A few small tweaks can take your broiled zucchini from good to great.
1. Don’t Skip the Oil
Oil helps zucchini broil evenly and prevents sticking.
2. Use a Wire Rack
A wire rack lets heat circulate so zucchini broil more evenly on all sides.
3. Add Toppings After Broiling
Cheese, lemon juice, and fresh herbs are best added after you broil zucchini.
4. Season Generously
Zucchini is mild, so it needs a good amount of salt and seasoning to shine.
So, How Long to Broil Zucchini in Oven?
You can broil zucchini in the oven in about 5 to 10 minutes per side, depending on thickness, heat, and rack position.
Thin slices broil fast, thicker planks take longer, and a hot broiler speeds everything up.
The key is to keep an eye on them and flip halfway through so both sides get that lovely char.
Now that you know exactly how long to broil zucchini in oven, you can whip up a batch any night of the week.
