Roasting carrots and broccoli takes about 20 to 30 minutes in a 425°F oven, depending on how you cut them and how crispy you like your veggies.
Carrots usually need a little more time than broccoli, so timing them right is the key to getting both perfectly tender and caramelized.
If you’ve ever wondered how long it takes to roast carrots and broccoli together without turning one into mush, you’re in the right place.
In this post, we’ll break down the exact roasting times for carrots and broccoli, plus tips to nail that golden, crispy finish every single time.
Let’s dive in.
How Long to Roast Carrots and Broccoli Together
When you roast carrots and broccoli together, plan for roughly 25 to 30 minutes total at 425°F.
The trick here is that carrots are denser, so they take longer to soften than broccoli florets do.
That means you’ll want to give carrots a head start of about 10 minutes before adding the broccoli to the pan.
If you toss everything in at once, the broccoli will likely burn at the edges before the carrots are even close to tender.
So the answer to how long it takes to roast carrots and broccoli really depends on whether you’re cooking them separately or together.
Roasting Carrots Alone
If you’re only roasting carrots, expect them to take about 25 to 35 minutes.
Cut them into sticks or coins about half an inch thick for even cooking.
Baby carrots can take a bit longer since they’re usually thicker and packed with moisture.
Roasting Broccoli Alone
Broccoli on its own roasts in about 20 to 25 minutes.
Smaller florets cook faster, so keep them around the same size for consistency.
You’ll know the broccoli is done when the tips turn dark and crispy while the stalks stay tender.
Factors That Affect Roasting Time for Carrots and Broccoli
Several things can change how long it takes to roast carrots and broccoli, so keep these in mind before you preheat that oven.
1. Size and Thickness of the Cuts
The size of your pieces matters more than almost anything else.
Thin carrot coins roast in 20 minutes, while thick chunks can take 40.
Same goes for broccoli, where large florets need extra time compared to small ones.
2. Oven Temperature
Most recipes call for 400°F to 425°F for roasting carrots and broccoli.
Lower temperatures around 375°F will take longer but give you softer, sweeter veggies.
Higher heat at 450°F speeds things up but demands more attention so nothing burns.
3. Pan Spacing and Crowding
If your veggies are piled on top of each other, they’ll steam instead of roast.
Give everything a little breathing room so the hot air can circulate and caramelize the edges.
A crowded pan can easily add 10 minutes to your total roasting time.
4. Fresh vs. Frozen Vegetables
Fresh carrots and broccoli roast faster and crisp up better than frozen ones.
Frozen veggies release extra water, which means they need more time and often end up softer.
If you’re using frozen, thaw and pat them dry first for the best results.
How to Roast Carrots and Broccoli Perfectly
Getting the timing right is only half the battle, so here’s how to roast carrots and broccoli like a pro.
1. Prep and Cut Evenly
Wash and chop your carrots and broccoli into similar-sized pieces.
Aim for carrot sticks about half an inch thick and broccoli florets roughly the same width.
Even pieces mean even roasting, which solves half your timing problems right there.
2. Toss With Oil and Seasoning
Coat everything in a couple tablespoons of olive oil, then season with salt, pepper, and garlic powder.
Don’t be shy with the oil, since it helps the veggies brown instead of drying out.
Spread them on a sheet pan in a single layer for the crispiest results.
3. Give Carrots a Head Start
Roast the carrots for 10 minutes before adding the broccoli to the pan.
This simple step is the secret to roasting carrots and broccoli together without one overcooking.
After 10 minutes, toss in the broccoli, stir everything, and roast for another 15 to 20 minutes.
4. Check and Flip Halfway Through
Around the halfway mark, give your veggies a good stir or flip with a spatula.
This helps them brown evenly on all sides and prevents sticking.
You’ll also get a feel for whether they need a few extra minutes.
5. Look for the Right Doneness Signs
Carrots are ready when they’re fork-tender with slightly caramelized edges.
Broccoli is done when the florets are crispy and the stalks are tender but not mushy.
If you’re unsure, just taste a piece, since that’s the most reliable test of all.
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 a 10-minute head start.
The exact time depends on your cut sizes, oven temperature, and whether you’re using fresh or frozen veggies.
Give the carrots a head start, keep your pieces even, and don’t crowd the pan.
Follow those simple rules, and you’ll have perfectly roasted carrots and broccoli every time.
Now go preheat that oven and enjoy your veggies.
