You can roast potatoes and carrots in an air fryer in about 20 to 25 minutes at 400°F (200°C), depending on how big you cut them.
That’s the short answer, and honestly, it’s one of the easiest side dishes you’ll ever make.
If you’ve been wondering how long to roast potatoes and carrots in air fryer so they come out crispy outside and tender inside, the timing mostly comes down to cube size, temperature, and a quick shake halfway through.
In this post, we’ll break down the exact roasting time for potatoes and carrots in the air fryer, plus tips to keep them from turning out soggy or burnt.
Let’s get right into it.
How Long to Roast Potatoes and Carrots in Air Fryer
The answer to how long to roast potatoes and carrots in air fryer is usually 20 to 25 minutes at 400°F.
But that number shifts a bit depending on a few key things.
1. The 400°F Sweet Spot
Roasting potatoes and carrots in the air fryer works best at 400°F (200°C).
This high heat gives you that golden, crispy exterior while the inside steams to a soft, fork-tender finish.
If you go lower, say 375°F, you’ll need closer to 28 to 30 minutes.
2. Cube Size Matters Most
Cut your potatoes and carrots into even 1-inch cubes for the most predictable results.
Smaller pieces, around half an inch, can roast in as little as 15 to 18 minutes.
Larger chunks, closer to 1.5 inches, may take 28 to 30 minutes, so keep them uniform for even cooking.
3. Shake the Basket Halfway
About 12 to 13 minutes in, pull the basket out and give it a good shake.
This simple step is what separates perfectly roasted potatoes and carrots from unevenly cooked ones.
It also keeps the pieces from sticking to the basket or steaming on one side.
Tips for Perfect Air Fryer Roasted Potatoes and Carrots
Getting the timing right is half the battle, but a few tricks make the final result even better.
1. Soak the Potatoes First
Soaking cubed potatoes in cold water for 15 minutes rinses off excess starch.
That starch is what makes potatoes steam instead of crisp, so soaking helps them roast up golden.
Just pat them completely dry before they hit the air fryer.
2. Don’t Skip the Oil
A tablespoon or two of oil helps the seasonings stick and encourages browning.
Toss the potatoes and carrots with oil, salt, pepper, and any herbs you like before air frying.
Olive oil, avocado oil, or even a light spray of cooking oil all work great here.
3. Avoid Overcrowding the Basket
If you pile too many potatoes and carrots into the basket, they’ll steam rather than roast.
Cook them in a single layer, and work in batches if you’re feeding a crowd.
This one tip alone can shave minutes off your roasting time and give you crispier edges.
4. Season at the Right Time
Salt, garlic powder, paprika, and rosemary are classic picks for roasted potatoes and carrots.
Add delicate herbs like fresh parsley after roasting so they don’t burn.
A squeeze of lemon or a sprinkle of parmesan at the end takes things up a notch.
Common Mistakes When Roasting Potatoes and Carrots in Air Fryer
Even with the right time, a few small slip-ups can ruin your batch.
1. Skipping the Preheat
Most air fryers benefit from a quick 3 to 5 minute preheat.
This ensures the potatoes and carrots start roasting the moment they hit the basket.
2. Cutting Pieces Unevenly
If your potato cubes are bigger than your carrot slices, they won’t finish at the same time.
Aim for uniform pieces so everything roasts evenly in that 20 to 25 minute window.
3. Forgetting to Check Early
Air fryer models vary, so start checking around the 18 minute mark.
Pierce a piece with a fork, and if it slides in easily, they’re done.
So, How Long to Roast Potatoes and Carrots in Air Fryer?
Roasting potatoes and carrots in an air fryer takes about 20 to 25 minutes at 400°F.
Cut them into even 1-inch cubes, toss them in oil and seasonings, and shake the basket halfway through.
With those simple steps, you’ll get crispy, tender roasted potatoes and carrots every single time.
So fire up that air fryer and enjoy your perfectly roasted veggies.
