How long to roast broccoli and carrots depends on the size of your pieces and the temperature of your oven.
Generally, roasted broccoli and carrots take about 20 to 30 minutes at 400°F (200°C).
If you’re wondering how long to roast broccoli and carrots together, the answer is simple: roast them at the same temperature but cut the carrots smaller so they cook evenly.
Knowing how long to roast broccoli and carrots is key to getting tender carrots and crispy broccoli edges every single time.
In this post, we’ll break down the exact roasting times for broccoli and carrots, plus tips for getting them perfectly done.
Let’s dive in.
How Long to Roast Broccoli and Carrots: The Exact Times
When you roast broccoli and carrots, the timing depends on a few factors.
Here’s a quick breakdown so you know exactly how long to roast broccoli and carrots in your oven.
1. Roasted Broccoli Takes 18 to 22 Minutes
Broccoli florets roast faster than carrots because they’re less dense.
At 400°F (200°C), broccoli florets need about 18 to 22 minutes.
You’ll know they’re done when the edges are crispy and the stems are tender.
If you like extra crispy broccoli, roast it for 25 minutes, but keep an eye on it so it doesn’t burn.
2. Roasted Carrots Take 25 to 35 Minutes
Carrots are denser, so they take longer to roast than broccoli.
At 400°F (200°C), carrot sticks or coins need about 25 to 35 minutes.
If your carrots are cut into thin coins, they’ll be done in about 25 minutes.
Thicker chunks may take up to 35 minutes or even 40 minutes for very large pieces.
3. Roasting Broccoli and Carrots Together
If you want to roast broccoli and carrots on the same sheet pan, cut the carrots into small, thin pieces.
This way, both veggies finish cooking at around the same time.
Start the carrots first for about 10 minutes, then add the broccoli.
Or cut carrots into matchsticks so they roast in 20 minutes alongside the broccoli.
Tips for Perfect Roasted Broccoli and Carrots
Now that you know how long to roast broccoli and carrots, here are a few tips to get the best results.
1. Cut Pieces to the Same Size
Even cooking starts with even cutting.
Cut broccoli florets and carrot pieces to roughly the same size.
This ensures everything roasts at the same rate, so nothing burns while something else stays raw.
2. Don’t Crowd the Pan
Spread your broccoli and carrots in a single layer on the baking sheet.
If they’re piled up, they’ll steam instead of roast.
Use two sheet pans if you’re roasting a big batch.
3. Toss with Oil and Seasonings
Coat your veggies with olive oil, salt, pepper, and garlic powder.
A little oil helps them brown beautifully and keeps them from drying out.
You can also add a squeeze of lemon juice after roasting for a bright finish.
4. Flip Halfway Through
Stir or flip your broccoli and carrots about halfway through roasting.
This helps them cook evenly and prevents one side from getting too dark.
Common Mistakes When Roasting Broccoli and Carrots
Even if you know how long to roast broccoli and carrots, a few mistakes can ruin the results.
1. Using a Low Oven Temperature
Roasting at 350°F (175°C) will take longer and won’t give you those crispy edges.
Stick with 400°F (200°C) or even 425°F (220°C) for the best texture.
2. Cutting Carrots Too Thick
Thick carrot chunks take much longer than broccoli.
If you’re roasting them together, always cut carrots smaller than you think you need.
3. Forgetting to Dry the Veggies
Wet broccoli and carrots will steam instead of roast.
Pat them dry with a towel before tossing them in oil.
4. Not Preheating the Oven
A hot oven is essential for roasting.
Preheat your oven for at least 10 to 15 minutes before adding the baking sheet.
So, How Long to Roast Broccoli and Carrots?
How long to roast broccoli and carrots comes down to this: broccoli needs 18 to 22 minutes, while carrots need 25 to 35 minutes at 400°F (200°C).
If you roast them together, cut the carrots smaller or give them a head start.
With the right timing and a few simple tips, you’ll get perfectly roasted broccoli and carrots every time.
Now you can confidently answer the question of how long to roast broccoli and carrots and enjoy a delicious, healthy side dish.
