To make the most amazing Air Fryer Sweet Potato Stacks, follow these straightforward steps:

1. Prep Sweet Potatoes: Wash and peel the sweet potatoes. Slice them into thin rounds, about 1/8 inch thick. A mandoline slicer works best for uniformity.

2. Season Sweet Potatoes: In a large bowl, combine the sweet potato slices, olive oil, garlic powder, paprika, salt, and pepper. Toss until evenly coated.

3. Preheat Air Fryer: Preheat your air fryer to 380°F (193°C) for about 3-5 minutes.

4. Arrange Stacks: Starting with one slice, layer four to five sweet potato rounds stacking them vertically. Secure each stack with a toothpick if needed.

5. Cook Stacks: Place a few stacks in the air fryer basket, ensuring they’re not overcrowded. Cook for 12-15 minutes, flipping halfway through for even crispiness.

6. Check for Doneness: After the initial cooking time, check the tenderness and crispness. If desired, add an additional 3-5 minutes until you reach your preferred texture.

7. Remove and Garnish: Carefully remove the stacks from the air fryer. Let them cool slightly and garnish with fresh herbs if using.

8. Serve Warm: These stacks are best served fresh and warm for maximum flavor and texture.
