Step-by-Step Instructions for Air Fryer Sweet Potato Cubes
- Preheat your air fryer to 400°F (200°C) for 3–5 minutes. A hot air fryer = crispy edges.
- Prep the sweet potatoes by peeling and cutting them into 1-inch cubes. Pat dry to remove excess moisture.
- Toss cubes in oil and seasoning. Use salt, pepper, and any optional spices you like. Don’t skimp—flavor matters.
- Place cubes in the air fryer basket in a single layer. Avoid overcrowding so they crisp evenly.
- Air fry for 12–15 minutes, shaking the basket halfway through. Check for golden, crispy edges and tender centers.
- Optional garnish with fresh herbs like rosemary or parsley. Serve immediately.
Tips for Perfect Air Fryer Sweet Potato Cubes
- Pat cubes dry before adding oil—less moisture = crispier edges.
- Don’t overcrowd the basket; let air circulate.
- Shake halfway through cooking for even browning.
- Experiment with spices: cinnamon + paprika = amazing sweet + smoky flavor.
- Serve hot—sweet potatoes cool quickly and lose some crispiness.
Common Mistakes to Avoid
- Cutting cubes unevenly – small cubes cook faster than large ones.
- Skipping preheat – sweet potatoes need heat to crisp.
- Overcrowding the air fryer – leads to steaming instead of roasting.
- Forgetting seasoning – bland sweet potatoes = sad sweet potatoes.
Substitutions & Alternatives
- Oil: olive, avocado, or coconut oil.
- Spices: smoked paprika, curry powder, cinnamon, chili powder.
- Herbs: rosemary, thyme, parsley, or sage.
- Other veggies: carrots, parsnips, or butternut squash cubes can be roasted the same way.
Sweet potatoes are forgiving—experiment to find your favorite flavor combo!
