Jacket potatoes, also known as baked potatoes, are a simple yet deeply satisfying comfort food. Their fluffy, steaming interior and crispy, golden-brown skin make them a versatile base for countless toppings, from classic butter and sour cream to gourmet combinations like smoked salmon and crème fraîche. Traditionally, baking potatoes meant a long wait in the oven, but the advent of air fryers, particularly the Ninja Air Fryer, has revolutionized the process. Air frying uses rapid circulation of hot air to cook food efficiently while crisping the exterior, producing perfectly baked potatoes in a fraction of the traditional oven time. In this guide, we’ll explore how to optimize temperature, timing, and technique to achieve ideal jacket potatoes every time.
Temperature is critical for baking potatoes in the air fryer. Too low, and the interior becomes undercooked while the skin struggles to crisp; too high, and the skin can burn before the flesh is properly cooked. For the Ninja Air Fryer, the optimal temperature is 400°F (204°C). This setting strikes the perfect balance between a tender, fluffy interior and a golden, slightly crisp skin. Preheating the air fryer to this temperature ensures even heat distribution, which is essential for consistent results, particularly if your potatoes are large or irregularly shaped.

Cooking time depends on potato size and variety, but generally, a medium to large potato requires 35-45 minutes at 400°F. Smaller potatoes may be done in around 30 minutes, while extra-large potatoes can take up to 50 minutes. The Ninja Air Fryer’s circulating hot air allows potatoes to cook evenly without the need for flipping in most cases, though rotating them halfway through the cooking time can further enhance uniform browning and crispness.
Perfectly baked jacket potatoes have a distinct combination of qualities:
If in doubt, cut open a potato; the flesh should separate easily and appear uniformly cooked.
The simplicity of jacket potatoes is part of their charm. For classic air fryer preparation, you need:
No additional ingredients are required, but high-quality oil and salt significantly improve the final texture and flavor.
Altering the temperature changes both cooking time and texture:
Temperature adjustments should always be coupled with monitoring doneness carefully.
Timing is equally crucial:
Always check the potato with a fork or skewer at the minimum recommended time, then adjust as necessary.
Even with an air fryer, mishaps can occur:
To bake jacket potatoes in a Ninja Air Fryer, set the temperature to 400°F (200°C). This high temperature allows the skin to become crispy while ensuring the potato inside is perfectly cooked and tender.
It typically takes around 35 to 40 minutes to bake jacket potatoes in a Ninja Air Fryer. Cooking time may vary depending on the size of the potatoes and the model of your air fryer. Be sure to check for tenderness by inserting a fork into the potato.
Yes, it is recommended to poke several holes in the potatoes with a fork before baking. This allows steam to escape during cooking, preventing the potatoes from bursting and ensuring an even bake.
While optional, it is a good idea to coat the potatoes with a light layer of oil (such as olive oil) before baking. This helps the skin become crispier and adds flavor. You can also season the potatoes with salt or other spices for added taste.
Yes, you can bake multiple jacket potatoes at once in your Ninja Air Fryer, but make sure they are not overcrowded. Leave enough space between each potato to allow for even airflow, which is essential for a crispy skin and even cooking.
Jacket potatoes are done when the skin is crispy and the inside is soft and tender. To check, insert a fork or skewer into the center of the potato. If it slides in easily and the flesh is fluffy, the potatoes are ready.
It is best to add toppings, such as cheese, sour cream, or bacon, after the potatoes are fully baked. If you add them during the cooking process, they may burn or overcook. You can, however, pop the potatoes back into the air fryer for a few minutes to melt cheese or heat up toppings if needed.
