How Long To Roast Broccoli And Zucchini

Roasting broccoli and zucchini takes about 15 to 25 minutes at 425°F (220°C), depending on how thick you cut them.
 
If you’ve ever wondered how long to roast broccoli and zucchini together, the good news is these two vegetables actually roast well side by side.
 
Broccoli usually needs a little more time than zucchini, so timing and placement matter.
 
In this post, we’ll break down exactly how long to roast broccoli and zucchini, how to prep them, and how to get that perfect crispy edge every single time.
 
Let’s get roasting.
 

How Long to Roast Broccoli and Zucchini Together

When you roast broccoli and zucchini together, plan for 15 to 25 minutes total in a 425°F oven.
 
Broccoli florets typically take 18 to 22 minutes to get tender with crispy tips.
 
Zucchini, on the other hand, cooks faster and is usually done in 12 to 18 minutes.
 
That difference is why you should either cut your zucchini into thicker pieces or add it to the pan a few minutes after the broccoli.
 
If you’re roasting them on separate sheet pans, you have full control.
 
But most people roast broccoli and zucchini on the same pan for convenience, and that works fine with a little planning.
 

1. Broccoli Roasting Time

Broccoli florets roast in 18 to 22 minutes at 425°F when cut into bite-sized pieces.
 
The stems need a bit longer, so cut them smaller than the florets or slice them thin.
 
You’ll know your broccoli is ready when the edges turn dark brown and the stems pierce easily with a fork.
 

2. Zucchini Roasting Time

Zucchini roasts in 12 to 18 minutes at 425°F, depending on the thickness of your slices.
 
Half-inch rounds take around 15 minutes, while thicker spears can take up to 20.
 
Zucchini releases a lot of water, so give the pieces space on the pan to avoid steaming.
 

3. Why the Timing Difference Matters

Zucchini has a much higher water content than broccoli, which is why it cooks faster.
 
If you toss both vegetables onto the same pan at the same time with equal-sized cuts, your zucchini will turn mushy before the broccoli is done.
 
So cut the zucchini in thicker chunks or slide it into the oven five minutes after the broccoli.
 

How to Prep Broccoli and Zucchini for Roasting

Prepping broccoli and zucchini for roasting is simple, but a few small steps make a big difference in how long they take to roast.
 
Here’s how to get both vegetables oven-ready.
 

1. Cut Them Into Even Pieces

Cut broccoli into florets that are roughly the same size so they roast evenly.
 
Slice zucchini into half-inch rounds or thick spears, which helps them hold their shape.
 
Even pieces mean even roasting, and that’s the whole game here.
 

2. Dry Them Well

Pat both vegetables dry with a clean kitchen towel or paper towels before roasting.
 
Excess moisture is the enemy of crispiness, especially with watery zucchini.
 
Dry vegetables roast faster and brown better.
 

3. Toss With Oil and Seasoning

Coat broccoli and zucchini with a couple of tablespoons of olive oil.
 
Add salt, pepper, garlic powder, and maybe a pinch of red pepper flakes.
 
Spread everything in a single layer on your sheet pan so nothing overlaps.
 

Tips for Perfectly Roasted Broccoli and Zucchini

Getting the timing right for how long to roast broccoli and zucchini is easier when you follow a few proven tips.
 
These small tweaks separate soggy vegetables from crispy, golden ones.
 

1. Preheat Your Oven Properly

Set your oven to 425°F and let it fully preheat before the vegetables go in.
 
A hot oven gives you that quick caramelization that keeps zucchini from turning to mush.
 

2. Use a Large Sheet Pan

Crowding the pan traps steam, and steamed zucchini is nobody’s favorite.
 
Use a pan big enough to spread the vegetables in a single layer with a little breathing room.
 

3. Flip Halfway Through

Flip the broccoli and zucchini about halfway through roasting.
 
This helps both sides brown evenly and prevents sticking.
 

4. Broil at the End for Extra Crisp

If you want extra crispy edges, broil the vegetables for the last one to two minutes.
 
Keep a close eye on them, because broccoli can go from perfect to burnt fast.
 

So, How Long to Roast Broccoli and Zucchini?

Roasting broccoli and zucchini takes about 15 to 25 minutes at 425°F, with broccoli needing slightly more time than zucchini.
 
If you’ve been unsure about how long to roast broccoli and zucchini in the same pan, just remember to cut the zucchini thicker or add it a few minutes later.
 
Dry them well, toss with oil and seasoning, spread them out, and let the oven do the rest.
 
Follow these tips and you’ll get tender broccoli and golden zucchini every time.
 
Now go preheat that oven.
