How long to roast beets and carrots depends on a few key factors, but generally speaking, beets take about 45 to 60 minutes while carrots need only 25 to 35 minutes in a 400°F oven.
Since these two root vegetables have different densities, they cook at different rates, which is why timing matters so much when you roast beets and carrots together.
If you’ve ever pulled a tray out of the oven only to find mushy carrots and rock-hard beets, you’re not alone.
In this post, we’ll break down exactly how long to roast beets and carrots, plus tips for getting them perfectly tender every single time.
Let’s dive in.
How Long to Roast Beets and Carrots Together
When you roast beets and carrots on the same sheet pan, the answer to how long to roast beets and carrots really comes down to size and technique.
Beets are dense and take much longer to soften, while carrots are lighter and cook faster.
The trick is to give the beets a head start so both vegetables finish at the same time.
Here’s how long to roast beets and carrots based on how you cut them:
1. Whole Beets and Whole Carrots
Whole beets typically need 50 to 60 minutes at 400°F, depending on their size.
Whole carrots, on the other hand, only need about 30 to 40 minutes.
If you’re roasting them whole together, add the carrots to the pan about 20 minutes after the beets go in.
That way, everything finishes around the same time.
2. Cubed Beets and Carrot Chunks
Cutting beets into 1-inch cubes brings the roast time down to about 35 to 45 minutes.
Carrots cut into similar chunks need roughly 25 to 30 minutes.
So if you’re wondering how long to roast beets and carrots when they’re cubed, plan for about 40 minutes total with the carrots going in 10 to 15 minutes later.
3. Thinly Sliced or Julienned
Thin slices roast fast, sometimes in as little as 20 minutes.
If you slice both beets and carrots thinly, you can roast them together for 20 to 25 minutes, flipping once halfway through.
Just keep an eye on them because thin pieces can burn quickly.
Factors That Affect How Long to Roast Beets and Carrots
Oven temperature, vegetable size, and even the type of pan you use all influence how long to roast beets and carrots.
Here are the main things to keep in mind:
1. Oven Temperature
Most recipes call for 400°F, which gives you a nice caramelized exterior.
If you drop the temperature to 375°F, add about 10 extra minutes to your roast time.
Higher heat, like 425°F, speeds things up but can cause burning if you’re not careful.
2. Size and Uniformity
The smaller and more uniform your pieces, the faster and more evenly they’ll cook.
Large beets can take over an hour, while baby beets might be done in 30 minutes.
Always aim for similar-sized pieces so everything roasts at the same pace.
3. Type of Pan
A dark-colored baking sheet absorbs more heat and can shave a few minutes off your roast time.
Lining your pan with parchment paper prevents sticking but can slightly slow browning.
Either way, the difference is minor, so don’t stress too much about it.
Tips for Roasting Beets and Carrots Perfectly
Getting the timing right is one thing, but a few simple tips can make your roasted beets and carrots truly shine.
1. Toss With Oil and Season Well
Coat your vegetables in olive oil so they roast evenly and develop those crispy edges.
Add salt, pepper, and herbs like thyme or rosemary for extra flavor.
2. Give Beets a Head Start
Since beets take longer, always start them first.
This is the single most important tip when figuring out how long to roast beets and carrots on one pan.
3. Check for Tenderness
Pierce the vegetables with a fork to test doneness.
If the fork slides in easily, they’re ready.
If there’s resistance, give them a few more minutes.
4. Don’t Crowd the Pan
Spread the vegetables in a single layer so they roast instead of steam.
Crowding leads to soggy results and uneven cooking.
So, How Long to Roast Beets and Carrots?
How long to roast beets and carrots comes down to giving beets 45 to 60 minutes and carrots 25 to 35 minutes at 400°F.
Since beets are denser, they need a head start of about 15 to 20 minutes before the carrots join them on the pan.
With the right timing, size, and a little patience, you’ll get tender, caramelized vegetables every time.
Now you know exactly how long to roast beets and carrots, so go ahead and give it a try tonight.
