The Essential Ingredients for a Perfect Sweet Potato
This recipe uses just a handful of the simplest pantry staples to create a spectacular result.
- Sweet Potatoes: The star of the show. For the best and most evenly cooked results in an air fryer, try to choose sweet potatoes that are relatively long and narrow, rather than short and round. This will help them cook through at the same rate. Look for potatoes with smooth, firm, and unbruised skin.
- Olive Oil: A light coating of olive oil is the key to that perfectly crispy, flavorful skin. The oil helps the skin to crisp up and get beautifully browned, rather than becoming dry and leathery. Avocado oil or another high-heat oil also works perfectly.
- Kosher Salt and Freshly Ground Black Pepper: The simple, essential seasonings. Generously seasoning the outside of the potato before cooking not only flavors the delicious skin but also helps to draw out a little bit of moisture, contributing to its crispiness.
- The Toppings (Butter & Chives): The classic and perfect finishing touch. A simple pat of unsalted butter melting into the fluffy flesh and a sprinkle of fresh, finely chopped chives is a timeless and delicious way to serve your sweet potato.
Step-by-Step to the Perfect Air Fryer Sweet Potato
Follow these simple, detailed steps for a perfect, crispy-on-the-outside, fluffy-on-the-inside result every time.
Step 1: Prep the Sweet Potatoes
First, scrub your sweet potatoes very well under running water to remove any dirt. Pat them completely dry with a paper towel. A dry potato will result in a crispier skin.
Using a fork, prick the sweet potatoes all over, about 8 to 10 times per potato.
Pro Tip: Do not skip this step! Pricking the skin is a crucial safety measure that allows steam to escape from the inside of the potato as it cooks, which prevents it from potentially bursting in your air fryer.
In a medium bowl, toss the dry, pricked sweet potatoes with the 2 teaspoons of olive oil, the 1/2 teaspoon of kosher salt, and a few grinds of black pepper until they are evenly and completely coated.
Step 2: Air Fry to Crispy, Fluffy Perfection
Place the coated potatoes in the basket of your 6-quart air fryer in a single layer.
Pro Tip: It’s important not to overcrowd your air fryer basket. The potatoes need space for the hot air to circulate all around them to get that perfectly crispy skin.
Cook at 400°F (200°C) for 35 to 40 minutes, flipping the potatoes over halfway through the cooking time.
The sweet potatoes are perfectly done when the skin is dry and crispy to the touch, and a sharp knife or a skewer can be inserted into the very center of the potato with absolutely no resistance. The cooking time will vary slightly depending on the exact size and thickness of your potatoes.
Step 3: Slice, Fluff, and Serve
Carefully remove the hot sweet potatoes from the air fryer basket.
Cut a slit lengthwise along the top of each potato, being careful of the hot steam that will be released.
Use a fork to gently fluff up the bright orange flesh on the inside. Season the inside with an extra pinch of salt.
Top each potato with a generous pat of butter and a sprinkle of freshly chopped chives. Serve immediately.

Frequently Asked Questions (FAQs)
Q1: Do I absolutely have to prick the sweet potatoes with a fork before air frying?
Yes, this is a very important safety step! As the sweet potato cooks at a high temperature, steam builds up inside. Pricking a few holes in the skin allows that steam to escape safely. If you don’t prick the skin, there is a small but real chance that the pressure could build up and cause the potato to burst inside your air fryer, which would create a huge mess.
Q2: How long does it really take to cook a whole sweet potato in the air fryer?
The cooking time will depend on the size and thickness of your sweet potato. For a standard, 8-ounce, relatively narrow sweet potato, 35 to 40 minutes at 400°F is a perfect timeframe. If your potato is much larger or rounder, it may need up to 45-50 minutes. The best way to check for doneness is to see if a sharp knife can be inserted into the center with zero resistance.
Q3: Can I cook more than two sweet potatoes at a time in my air fryer?
It depends on the size of your air fryer. The most important rule is to not overcrowd the basket. The potatoes should be in a single layer with some space around them for the hot air to circulate. If the potatoes are packed in too tightly, they will steam instead of roast, and you will not get that signature crispy skin.
Q4: Is it healthier to cook a sweet potato in the air fryer than to bake it in the oven?
The nutritional content of the sweet potato itself will be virtually the same whether you cook it in the air fryer or the oven. The main benefits of using an air fryer are speed and energy efficiency. It cooks much faster and uses less electricity than heating up a large, conventional oven.
Q5: Should I wrap my sweet potatoes in foil when I air fry them?
No, you should not wrap them in foil for this recipe. Wrapping a potato in foil will trap the steam, which will result in a soft, steamed skin rather than the delicious, dry, and crispy skin that the direct, circulating hot air of the air fryer creates.
