Instructions
Air Fryer Roasted Sweet Potatoes
- Preheat your air fryer to 400°F for 3 minutes to jump start browning.
- Peel if you prefer, or leave skins on. Cut into 1/2-inch cubes. Rinse quickly and pat very dry to remove surface starch.
- In a bowl, toss cubes with oil, salt, pepper, garlic powder, smoked paprika, and cinnamon (if using). Sprinkle cornstarch last and toss again to lightly coat.
- Spread in a single layer in the preheated basket. Cook at 400°F for 12 to 16 minutes, shaking the basket every 5 minutes. Cook in batches if needed to avoid crowding.
- They’re done when edges are deeply golden and centers are tender. Taste and adjust salt. Finish with lime juice, a dusting of paprika, or chopped herbs.
Storage & Reheating
- Fridge: airtight up to 4 days. Freezer: freeze on a tray, then bag up to 2 months. Reheat: air fryer 375°F for 3–5 minutes; oven 400°F for 5–8 minutes; microwave 30–60 seconds for softer texture. Re-crisp with a light spray of oil before reheating.

Step-by-Step Instructions to Make Roasted Sweet Potatoes Air Fryer
Step 1: Preheat the air fryer
Preheat your air fryer to 400°F for 3 minutes. A hot basket jump starts browning.
Step 2: Prep and cut the potatoes
Peel if you prefer, or leave skins on for more texture. Cut into 1/2 inch cubes for even cooking. Rinse quickly and pat very dry with a clean towel to remove surface starch.
Step 3: Season generously
Add the cubes to a bowl. Toss with oil, salt, pepper, garlic powder, smoked paprika, and cinnamon if using. Sprinkle cornstarch last and toss again so it clings lightly to the oiled potatoes.
Step 4: Air fry and shake
Spread potatoes in a single layer in the preheated basket. Cook at 400°F for 12 to 16 minutes, shaking the basket every 5 minutes. Cook in two batches if your basket is small to avoid crowding.
Step 5: Finish and serve
They are done when edges are deeply golden with a crisp bite and centers are tender. Taste and adjust salt. Finish with a squeeze of lime, a dusting of paprika, or chopped herbs.
Tips for Success
- Cut evenly to 1/2 inch cubes for consistent doneness
- Do not overcrowd the basket or they will steam
- Preheat for better browning and crisp edges
- Add cornstarch after oiling for a thin, crunchy coating
- Let them rest 2 minutes after cooking so surfaces set and stay crisp

Memories Made Around the Table
On busy weeknights, this was the side that got my family to the table with smiles. A little paprika, a squeeze of lime, and suddenly it tasted like more than the sum of its parts.
FAQs
Do I need to peel the sweet potatoes? No. The skin adds fiber and a lovely chew. Peel for a smoother bite if you prefer.
Why did my potatoes turn out soft instead of crisp? Likely crowding or insufficient drying. Spread in a single layer, pat dry before seasoning, and shake the basket during cooking.
Can I make these oil free? Yes. Skip oil and season with dry spices, but texture will be less crisp. Add 1 tsp aquafaba for a lighter coating that helps spices stick.
Can I use frozen sweet potato cubes? Yes. Cook from frozen at 400°F for 16 to 20 minutes and season after the first shake so spices adhere.
