You can roast carrots and potatoes in the oven easily by tossing them in oil, seasoning them well, and spreading them on a sheet pan to bake until golden and tender.
This classic combo is one of the simplest and most satisfying side dishes you can make at home.
The oven does most of the work, caramelizing the natural sugars in the carrots and crisping the edges of the potatoes.
If you’ve ever wondered how to roast carrots and potatoes in the oven so they come out perfectly every time, you’re in the right place.
In this post, we’ll walk through how to roast carrots and potatoes in the oven step by step, plus tips for getting them crispy, flavorful, and evenly cooked.
How to Roast Carrots and Potatoes in the Oven
Roasting carrots and potatoes in the oven comes down to a few key steps.
Get these right and you’ll have a foolproof side dish for weeknights, holidays, or meal prep.
1. Preheat and Prep Your Oven
Start by preheating your oven to 425°F (220°C).
A hot oven is essential when you roast carrots and potatoes because it gives them that golden, crispy exterior.
While the oven heats up, line a large sheet pan with parchment paper or give it a light coat of oil.
Don’t crowd the pan—if the veggies are piled up, they’ll steam instead of roast.
2. Cut Everything Into Even Pieces
When you roast carrots and potatoes, size matters more than you’d think.
Cut your potatoes into roughly 1-inch chunks and your carrots into similar-sized pieces.
This helps them cook at the same rate so nothing ends up mushy or underdone.
If your carrots are thick, slice them in half lengthwise first so they roast evenly alongside the potatoes.
3. Toss With Oil and Seasonings
Drizzle both veggies with olive oil or avocado oil—about 2 to 3 tablespoons for a full pan.
Toss until every piece is coated, then season generously with salt, black pepper, garlic powder, and dried herbs like rosemary or thyme.
This is the step that makes roasted carrots and potatoes taste so good, so don’t be shy with the seasoning.
4. Spread Them in a Single Layer
Spread the carrots and potatoes out in one even layer on your sheet pan.
Leave a little space between pieces so the heat can circulate and crisp them up.
If your pan is too small, use two pans—trust me, it’s worth it when you roast carrots and potatoes.
5. Roast, Flip, and Roast Again
Slide the pan into the oven and roast for about 25 minutes.
Then pull it out, flip the pieces with a spatula, and return it to the oven for another 15 to 20 minutes.
You’ll know they’re done when the potatoes are fork-tender and the carrots are caramelized at the edges.
Total roasting time is usually 40 to 45 minutes, depending on how big you cut them.
Tips for Perfectly Roasted Carrots and Potatoes
Want to roast carrots and potatoes like a pro?
Here are a few simple tips that make a big difference.
1. Parboil the Potatoes for Extra Crispiness
If you love crispy roasted potatoes, boil them for 5 to 7 minutes before roasting.
Drain them well, let them steam dry, then toss with oil and seasonings.
This roughs up the surface and helps them crisp beautifully when you roast carrots and potatoes together.
2. Keep Carrots and Potatoes Separate If Needed
Carrots tend to cook a little faster than potatoes.
If your pieces are uneven, roast the potatoes first for 10 minutes, then add the carrots.
That way everything finishes at the same time when you roast carrots and potatoes in the oven.
3. Add Fresh Herbs at the End
Dried herbs go in before roasting, but fresh herbs like parsley or dill should go on after.
Sprinkle them over your roasted carrots and potatoes right when they come out of the oven.
The residual heat will release their aroma without burning them.
4. Don’t Skip the Flip
Flipping halfway through is one of the easiest ways to get even browning.
It helps every side of your carrots and potatoes make contact with the hot pan.
Skip this step and you’ll end up with one crispy side and one pale side.
What to Serve With Roasted Carrots and Potatoes
Roasted carrots and potatoes pair with just about anything.
Serve them next to roast chicken, grilled steak, baked salmon, or a hearty meatloaf.
They also work great in bowls with grains and greens for a simple vegetarian meal.
And if you have leftovers, they reheat well in a hot skillet or a quick stint in the oven.
So, How Do You Roast Carrots and Potatoes in the Oven?
You roast carrots and potatoes in the oven by cutting them evenly, tossing them in oil and seasonings, spreading them on a sheet pan, and baking at 425°F for about 40 to 45 minutes, flipping halfway.
It’s a simple method that delivers crispy, caramelized results every single time.
Whether you’re making a quick weeknight side or a holiday spread, knowing how to roast carrots and potatoes in the oven is a skill worth having.
So grab your sheet pan, preheat that oven, and roast carrots and potatoes tonight.
