Baking broccoli and sweet potatoes takes about 20 to 35 minutes at 400°F (200°C), depending on how you cut them and whether you’re baking them together or separately.
Broccoli usually roasts in 20 to 25 minutes, while sweet potatoes need 25 to 35 minutes when cubed, or up to 45 to 60 minutes if you bake them whole.
The good news is you can absolutely bake broccoli and sweet potatoes at the same time on the same sheet pan with a little timing strategy.
If you’ve been wondering how long to bake broccoli and sweet potatoes so they both come out perfectly tender and caramelized, this post breaks it all down.
In this post, we’ll cover exactly how long to bake broccoli and sweet potatoes, the best temperature to use, and the tips that keep both veggies from turning mushy or burnt.
Let’s get roasting.
How Long to Bake Broccoli and Sweet Potatoes
How long to bake broccoli and sweet potatoes depends on a few key factors, but here are the general timeframes to work with:
1. Broccoli Bakes in 20 to 25 Minutes
When you bake broccoli at 400°F, it typically takes 20 to 25 minutes to get those crispy edges and tender stems.
Smaller florets bake faster, closer to 18 to 20 minutes, while larger pieces may need the full 25.
The key is to toss broccoli in oil, spread it in a single layer, and check it around the 18-minute mark so it doesn’t overcook.
2. Cubed Sweet Potatoes Need 25 to 35 Minutes
If you’re baking cubed sweet potatoes, expect them to take about 25 to 35 minutes at 400°F.
Cut them into even 1-inch cubes so they bake at the same rate.
Larger chunks can take closer to 35 to 40 minutes, and whole sweet potatoes baked in the oven take 45 to 60 minutes.
3. Whole Sweet Potatoes Take 45 to 60 Minutes
Whole sweet potatoes take much longer than broccoli, so this is where timing matters.
If you want to bake whole sweet potatoes alongside broccoli, start the sweet potatoes first and add the broccoli later.
Or cube the sweet potatoes so both veggies finish around the same time.
4. Oven Temperature Matters
Most recipes for baking broccoli and sweet potatoes call for 400°F (200°C).
At 425°F, both bake faster but the broccoli can char before the sweet potatoes are done.
At 375°F, you’ll need to add about 5 to 10 minutes to the bake time for both vegetables.
How to Bake Broccoli and Sweet Potatoes Together
Baking broccoli and sweet potatoes on the same sheet pan is totally doable if you follow a few smart steps:
1. Give the Sweet Potatoes a Head Start
Since sweet potatoes take longer, give them a 10-minute head start on the sheet pan before adding the broccoli.
This way, by the time the broccoli is done, the sweet potatoes are perfectly tender too.
2. Cut Everything Into Similar Sizes
Cut sweet potatoes into 1-inch cubes and broccoli into medium florets so they bake evenly.
Even sizing is the secret to knowing exactly how long to bake broccoli and sweet potatoes without guessing.
3. Don’t Crowd the Pan
Use a large sheet pan and spread the veggies in a single layer with space between them.
Crowding steams the vegetables instead of roasting them, which means mushy broccoli and pale sweet potatoes.
Use two pans if needed.
4. Toss With Oil and Season Early
Coat both vegetables in olive oil, salt, and pepper before baking.
This helps them caramelize and keeps the broccoli from drying out.
Tips for Perfectly Baked Broccoli and Sweet Potatoes
Here’s how to nail the timing every single time you bake broccoli and sweet potatoes:
1. Preheat the Oven Fully
Always preheat to 400°F before baking broccoli and sweet potatoes.
A hot oven gives you that roasted texture instead of a steamed one.
2. Flip Halfway Through
Stir or flip the veggies around the halfway point so they brown evenly on all sides.
3. Check Doneness With a Fork
Sweet potatoes are done when a fork slides in easily.
Broccoli is done when the stems are tender and the edges are crispy.
4. Watch the Broccoli Closely
Broccoli can go from perfect to burnt quickly, so check it a few minutes before the timer goes off and pull it early if needed.
So, How Long to Bake Broccoli and Sweet Potatoes?
Baking broccoli and sweet potatoes takes about 20 to 35 minutes at 400°F, with broccoli finishing on the faster end and cubed sweet potatoes taking a bit longer.
Whole sweet potatoes need 45 to 60 minutes, so give them a head start if you’re baking everything together.
Now that you know how long to bake broccoli and sweet potatoes, you can get perfectly roasted veggies on the table with zero guesswork.
Happy roasting.
