Air Fry Sweet Potato Cubes (A Quick My Story about)
A few months ago, I had one of those classic “it’s 5:45pm and I have zero dinner plans” kind of nights. My youngest had soccer practice, the fridge was basically empty, and I was this close to declaring it cereal-for-dinner night.
But then I remembered the two sweet potatoes sitting quietly in the corner of the pantry — like little orange lifesavers. I chopped them up, tossed them in some oil and spices, and popped them in the air fryer while I reheated leftovers.
Five minutes later, my daughter walked in and said, “Mom, it smells like Chick-fil-A fries in here.”
Honestly? That was the moment this Air Fry Sweet Potato Cubes recipe became a permanent part of our dinner rotation.
Sometimes the simplest meals turn out to be the most memorable.

Step-by-Step: How to Make Air Fry Sweet Potato Cubes
1. Cube & Season
Peel your sweet potatoes and chop them into about ½-inch cubes. (Think “bite-sized, but not tiny.”) Toss them into a bowl with the oil and seasonings. Give it a good stir — no bare potato bits allowed.
2. Preheat & Air Fry
Preheat your air fryer to 400°F. Add your seasoned sweet potatoes in a single layer — super important! Crowding the basket = soggy cubes.
Air fry for 10–12 minutes, shaking halfway through. If your air fryer runs hot, check at 9 minutes.
🔥 Pro Tip: No need to boil before! Straight to the air fryer, baby!
3. Optional Oven Method
No air fryer? No problem.
Preheat your oven to 425°F. Spread seasoned cubes on a lined sheet pan (not overlapping). Roast for 25–30 minutes, flipping halfway through.

Can I Customize These Sweet Potato Cubes? (FAQs)
Can I use olive oil instead of avocado oil?
Absolutely. Any neutral oil works. Avocado oil just has a higher smoke point and subtle flavor.
Can I store leftovers?
Sure, but they’re best fresh. Reheat in the air fryer at 375°F for 3–4 minutes to revive the crisp.
How do I make these sweet instead of savory?
Skip the garlic/pepper and add a sprinkle of cinnamon, a dash of brown sugar, and maybe a drizzle of maple syrup. Your house will smell like the holidays.
Is this recipe healthy?
Yes! Sweet potatoes are high in fiber and vitamin A. Plus, you’re using way less oil than traditional roasting.
