How Long Does It Take To Roast Carrots And Broccoli

Roasting carrots and broccoli takes about 20 to 30 minutes in a 425°F (220°C) oven, depending on how you cut them and whether you roast them together or separately.
 
Carrots usually need a little longer since they’re denser, while broccoli florets cook faster and can go from perfectly crisp to charred in just a few extra minutes.
 
If you’ve been wondering how long to roast carrots and broccoli so both come out tender and caramelized at the same time, the answer comes down to a few simple tricks.
 
In this post, we’ll break down exactly how long to roast carrots and broccoli, how to prep them so they finish together, and the mistakes that throw off your timing.
 
Let’s get into it.
 

How Long to Roast Carrots and Broccoli

Roasting carrots and broccoli together takes roughly 20 to 30 minutes at 425°F, and here’s how that timing breaks down:

1. Carrots Need 25 to 30 Minutes

Carrots are dense root vegetables, so they take the longest to soften and caramelize.
 
If you’re roasting carrot sticks or coins about ¼-inch thick, plan on 25 to 30 minutes.
 
Whole carrots or thick chunks can take 35 to 40 minutes, so cut them smaller if you want everything done at once.
 
The good news is that roasting carrots and broccoli in the same pan works beautifully as long as you give the carrots a head start.
 

2. Broccoli Needs 15 to 20 Minutes

Broccoli florets roast much faster than carrots because they’re less dense and contain more water.
 
At 425°F, broccoli florets typically take 15 to 20 minutes to turn tender with crispy, browned edges.
 
If you roast broccoli on its own, that’s your full roasting time.
 
But when you’re roasting carrots and broccoli together, add the broccoli about 10 minutes after the carrots go in.
 

3. Oven Temperature Matters

Most recipes for roasting carrots and broccoli call for 400°F to 425°F.
 
At 400°F, add about 5 minutes to each timeframe.
 
At 425°F, you get faster caramelization and that slightly charred edge everyone loves.
 
Just keep an eye on the broccoli toward the end, because a hot oven can take it from crispy to burnt quickly.
 

How to Prep Carrots and Broccoli for Even Roasting

Getting the timing right when roasting carrots and broccoli starts before they hit the oven, so prep them like this:

1. Cut Them to Similar Sizes

Cut carrots into sticks or coins about ¼-inch thick, and cut broccoli into florets of similar size.
 
When pieces are uniform, they roast at the same rate instead of some burning while others stay raw.
 
This one step does more for your roasting carrots and broccoli results than any other tip.
 

2. Dry the Broccoli Thoroughly

Wet broccoli steams instead of roasts, which throws off your timing completely.
 
Pat the florets dry with a clean towel after washing them.
 
Dry broccoli will brown and crisp in 15 to 20 minutes, while damp broccoli may take closer to 25 and never get crispy.
 

3. Don’t Crowd the Pan

When roasting carrots and broccoli, spread them in a single layer with a little space between pieces.
 
A crowded pan traps steam, and your vegetables end up soggy instead of caramelized.
 
Use a large sheet pan, or split everything between two pans if needed.
 

Tips for Roasting Carrots and Broccoli Perfectly

A few extra tips will keep your carrots and broccoli roasting evenly every single time:

1. Give Carrots a 10-Minute Head Start

The simplest way to nail the timing for roasting carrots and broccoli in one pan is to roast the carrots alone for 10 minutes first.
 
Then add the broccoli and roast everything for another 15 to 20 minutes.
 
That way both vegetables finish at the same moment.
 

2. Toss With Enough Oil

Use about 2 tablespoons of olive oil for a standard sheet pan of carrots and broccoli.
 
Enough oil helps them brown evenly and keeps the timing predictable.
 
Too little oil means dry, uneven roasting, and too much means steaming.
 

3. Season Simply and Check Early

Salt, pepper, and garlic powder are all roasting carrots and broccoli really need.
 
Start checking at the 15-minute mark for the broccoli and 25 minutes for the carrots.
 
Oven temperatures vary, so let what you see in the pan guide you more than the clock.
 

So, How Long Does It Take to Roast Carrots and Broccoli?

Roasting carrots and broccoli takes about 20 to 30 minutes at 425°F, with carrots needing 25 to 30 minutes and broccoli needing 15 to 20.
 
Give the carrots a 10-minute head start, cut everything to even sizes, and keep the pan uncrowded.
 
Follow those steps, and your roasted carrots and broccoli will come out tender, caramelized, and ready to serve.
