Whole Sweet Potato in Air Fryer
Luke and Kay – Flawless Food
These air fryer sweet potatoes are easy, healthier than a traditional oven bake and delicious. The air fryer crisps the skin while keeping the flesh soft and fluffy. If you’re in a hurry, use the microwave first, then finish in the air fryer for a quicker result (skin will be less crisp). Store cooked potatoes in the fridge for up to four days or in the freezer for up to three months.

Equipment
- Air fryer
- Sharp knife
- Glass mixing bowl
- Microwave (optional for the quicker method)
Ingredients
- 2 sweet potatoes (about 290 g / 10.2 oz each)
- 1 teaspoon oil (olive, avocado or other)
- Salt, to taste
Instructions — Air Fryer Method (Best)
- Prick each sweet potato a few times with a fork or sharp knife. This prevents steam buildup and helps even cooking. Do not stack potatoes in the air fryer; cook in a single layer.
- Place the potatoes in a bowl. Drizzle with 1 teaspoon of oil and rub to coat the skins evenly, or use a spray oil.
- Sprinkle salt over the skins and rub it in so the seasoning adheres.
- Transfer the potatoes to the air fryer basket. Cook at 200°C / 400°F for about 40 minutes, turning once halfway through for even browning.
- Check doneness by inserting a sharp knife into the centre—if it meets no resistance, the potatoes are done. If still firm, continue cooking in 2-minute intervals until tender.
- Remove, split open and serve with your favourite toppings.
Quicker Microwave + Air Fryer Method (less crispy skin)
- Prick each potato and place on a microwave-safe plate. Microwave on high, turning once halfway through. Times vary by microwave power and potato size. As a guide for large (~290 g) potatoes: 1 potato = 4 minutes, 2 = 6 minutes, 3 = 8 minutes, 4 = 10 minutes.
- Check with a knife; if still firm, continue in 1-minute bursts until soft.
- Toss microwaved potatoes in a bowl with 1 teaspoon oil and salt, then air fry at 200°C / 400°F for 8 minutes to add some crispness to the skin.
How to Check Doneness
Insert a knife into the centre—if it slides in easily the potato is cooked. If there’s resistance, air fry a bit longer and test again.
Tip: Choose sweet potatoes of similar size to ensure even cooking. Avoid potatoes with very skinny ends, which cook faster than the centre.

Ingredients
The ingredient list is intentionally short—this recipe shines because of its simplicity. You only need sweet potatoes, a little oil and salt. Optional seasonings can be added to taste for more complexity.
Oil
A light coating of oil helps the skin crisp and prevents the flesh from drying out. Olive, avocado or coconut oil all work well. Use spray oil if you prefer less oil, or omit it altogether if you want an oil-free result—expect less crisp skin in that case.
Seasoning Ideas
Salt is essential. For variety, mix salt with black pepper, garlic powder, smoked paprika or dried herb blends before rubbing it onto the skin. Fresh herbs such as chives, parsley or cilantro are best added after cooking for a bright finish.
Instructions — Summary
1) Prick sweet potatoes. 2) Toss in oil and salt. 3) Air fry at 200°C / 400°F for about 40 minutes, turning once. 4) Test with a knife and serve with fillings or toppings of your choice.
Quickest Method: Microwave + Air Fryer
If you need dinner faster, microwave the potatoes until soft, then finish in the air fryer for a few minutes to add texture. This saves time but will not achieve the same deep crispiness as the full air-fry method.
Serving Suggestions
These air-fried sweet potatoes work as a side with roasted or grilled proteins, or as a main when loaded with toppings. Popular fillings include chilli con carne, chicken curry, tuna mayo, prawn cocktail, egg mayo with bacon, baked beans and cheese, coronation chicken, or a simple topping of sour cream and chives.
Storage and Reheating
Store cooled potatoes in an airtight container in the fridge for 3–4 days. Refrigerate within two hours of cooking. To freeze, place in a sealed container for up to three months and defrost overnight in the fridge.
Reheat quickly in the microwave for 2–3 minutes (skin will soften) or refresh in the air fryer at 200°C / 400°F for 5 minutes to re-crisp the skin.
