How long do you roast carrots and potatoes?
The answer depends on how you cut them and at what temperature you roast them, but generally speaking, carrots and potatoes roast in about 25 to 45 minutes at 425°F (220°C).
If you’ve been wondering how long to roast carrots and potatoes together in the same pan, the sweet spot is usually around 30 to 35 minutes for bite-sized chunks.
The exact time you roast carrots and potatoes depends on a few key factors like size, density, and whether you’re roasting them whole or chopped.
In this post, we’ll break down exactly how long you should roast carrots and potatoes based on how you prep them, so you never end up with burnt carrots and raw potatoes again.
Let’s get roasting.
How Long to Roast Carrots and Potatoes Together
When you roast carrots and potatoes together, timing matters because these two vegetables cook at slightly different speeds.
Here’s how long to roast carrots and potatoes based on the most common cuts.
1. Cubed Carrots and Potatoes (1-inch pieces)
When you cut both vegetables into 1-inch cubes, roast carrots and potatoes for about 30 to 35 minutes at 425°F.
This is the most popular way to roast carrots and potatoes because the pieces cook evenly and finish at roughly the same time.
Toss them in oil, spread them in a single layer, and flip halfway through for golden edges.
2. Wedges or Thick Chunks (2-inch pieces)
If you roast carrots and potatoes as wedges or larger chunks, plan for 40 to 45 minutes at 425°F.
Larger pieces need more time for heat to penetrate the center, especially dense potatoes.
Cut your carrots slightly thicker than your potatoes if you can, since carrots tend to soften faster.
3. Whole Baby Carrots and Halved Baby Potatoes
When you roast carrots and potatoes in their smaller forms, like baby carrots and halved baby potatoes, 25 to 30 minutes at 425°F usually does the trick.
Baby carrots are already uniform in size, so they roast quickly and evenly.
Just keep an eye on them so they don’t shrivel up before the potatoes are done.
4. Whole Roasted Carrots and Potatoes
If you’re roasting whole carrots and whole potatoes, be ready to wait 50 to 60 minutes.
Whole potatoes take the longest because of their density, so pierce them with a fork before roasting to help heat escape and cook the inside faster.
Whole carrots, on the other hand, will finish sooner, so you may need to pull them out earlier.
What Temperature Do You Roast Carrots and Potatoes At?
The best temperature to roast carrots and potatoes is 425°F (220°C).
This high heat gives you that crispy exterior and tender interior everyone loves.
If you’re roasting carrots and potatoes at a lower temperature like 375°F, expect to add about 10 to 15 minutes to your total roasting time.
Roasting carrots and potatoes at 400°F is a good middle ground if you’re worried about burning the edges.
Just remember, the lower the heat, the longer you roast carrots and potatoes.
Tips for Perfectly Roasted Carrots and Potatoes
Knowing how long to roast carrots and potatoes is only half the battle.
Here’s how to make sure they come out perfectly every time.
1. Cut Them the Same Size
When you roast carrots and potatoes, uniform pieces are everything.
If your potatoes are in big chunks and your carrots are in thin coins, the carrots will burn before the potatoes are cooked through.
Aim for pieces that are all roughly the same size so everything finishes together.
2. Don’t Crowd the Pan
If you pile carrots and potatoes too close together, they’ll steam instead of roast.
Use a large sheet pan and spread them in a single layer with a little space between each piece.
This is the difference between soggy vegetables and perfectly caramelized ones.
3. Parboil the Potatoes First
One trick to roast carrots and potatoes evenly is to parboil the potatoes for 5 to 7 minutes before roasting.
This gives them a head start so they finish at the same time as the carrots.
Drain them well and pat them dry before tossing them in oil.
4. Flip Halfway Through
About halfway through the roasting time, flip your carrots and potatoes with a spatula.
This ensures both sides get that golden, crispy finish.
5. Season After Roasting Too
Salt and pepper before roasting is great, but a little sprinkle of fresh herbs or flaky salt after you roast carrots and potatoes takes them to the next level.
So, How Long Do You Roast Carrots and Potatoes?
You roast carrots and potatoes for about 25 to 45 minutes at 425°F, depending on how you cut them.
Cubed pieces take around 30 to 35 minutes, while larger wedges and whole vegetables need 40 to 60 minutes.
The key is to cut them evenly, give them space on the pan, and flip them halfway through.
Now that you know exactly how long to roast carrots and potatoes, you can get them in the oven with confidence and enjoy a perfectly golden side dish every single time.
