Ingredients for Air Fryer Sweet Potato

This is a quick overview of what you’ll need. The full recipe card below has exact measurements and instructions.

• Sweet potatoes: 3 cups of 1/2-inch cubes (about 2 medium sweet potatoes). You can buy pre-cut cubes to save time.
• Oil: Olive oil or avocado oil.

• Cornstarch: The secret to crispiness; it helps form a golden exterior while keeping the inside fluffy.

How to make Air Fryer Sweet Potato Cubes

You only need an air fryer and a mixing bowl. Follow these steps for the best results.

Prepare the Sweet Potatoes

Wash and peel whole sweet potatoes if needed. Use a sharp knife to cut into 1/2-inch cubes, aiming for uniform pieces so they cook evenly. If you have pre-cut cubes, skip this step.

Mix the Spices

Combine brown sugar, chili powder, paprika, cumin, garlic powder, cornstarch, and a pinch of salt in a small bowl. Mixing the dry ingredients first ensures even seasoning.

Add Oil and Spices

Toss the sweet potato cubes with the oil to coat, then sprinkle the spice-cornstarch mixture over them and toss again until evenly covered.

Air Fry

Preheat the air fryer to 390°F (199°C) for about 3 minutes. Add the seasoned sweet potatoes and cook for 6 minutes, shake or toss the basket, then cook an additional 6 minutes or until the cubes are crisp on the outside and tender inside.

Serve

Serve immediately while hot, seasoning with additional salt and pepper if needed. These sweet potato cubes complement many entrees; favorites include:

• Blackened pork chops—the spices pair wonderfully with the sweet potatoes.
• Grilled pork tenderloin for a complete, flavorful meal.
• Air fryer shrimp for a quick protein to go alongside the potatoes.
• Cheesy chicken dishes or roasted chicken for a comforting plate.
• Baked pork chops for a simple family dinner.

What air fryer should I use?

This recipe works with any air fryer. A 4-quart basket-style model fits this portion well, but rack-style air fryers will yield the same results.
