Let’s dive in.
How Long to Roast Potatoes and Carrots in Air Fryer
Roasting potatoes and carrots in an air fryer takes roughly 20 to 25 minutes at 380°F, with a shake halfway through.
Here’s what shapes that number:
1. Chop Size Decides Everything
The single biggest factor in how long to roast potatoes and carrots in air fryer is how big you cut them.
One-inch cubes of potato and half-inch carrot coins cook in about 20 minutes.
Bigger wedges or thick carrot chunks can push the roasting time for potatoes and carrots in an air fryer closer to 28 or even 30 minutes.
Aim for uniform pieces so everything finishes at the same time.
2. Temperature and Preheating
Set your air fryer to 380°F for the best balance of crispy outside and fluffy inside.
If your air fryer has a preheat function, use it.
Preheating shaves a few minutes off how long to roast potatoes and carrots in air fryer and gives you more even browning.
Some models run hot, so check at the 18-minute mark the first time you make this.
3. Give Them a Shake Midway
Around the 10 to 12 minute mark, pull the basket out and shake it.
This simple step is why roasted potatoes and carrots in an air fryer come out evenly crisp instead of burnt on top and pale underneath.
Shake once, maybe twice if you packed the basket full.
4. Don’t Overcrowd the Basket
Air fryer roasting depends on hot air circulating around every piece.
If you pile potatoes and carrots in too deep, they steam instead of roast, and your cooking time gets unpredictable.
Cook in a single layer, and work in batches if you’re feeding a crowd.
How to Roast Potatoes and Carrots in Air Fryer Perfectly
Knowing how long to roast potatoes and carrots in air fryer is half the battle.
The other half is prep, and these steps make a real difference:
1. Cut Them Even and Similar in Size

2. Toss With Oil and Seasoning
A tablespoon or two of olive oil helps them crisp and keeps the seasoning stuck.

If it slides in easily, you’re close to done.
If not, add 3 to 5 more minutes.
