Preparation Phase & Tools to Use

Essential Tools and Equipment

  • Air fryer (5-quart or larger for batch cooking)
  • Sharp chef’s knife or mandoline
  • Vegetable peeler
  • Large mixing bowl
  • Clean kitchen towel or paper towels
  • Measuring spoons
  • Silicone tongs

Importance of Each Tool

  • The air fryer is crucial for even, oil-free cooking.
  • A sharp knife or mandoline ensures uniform fry thickness.
  • A mixing bowl is used to evenly coat fries with seasoning.
  • Tongs help flip and retrieve fries without damaging them.

Preparation Tips

  • Choose firm, unblemished sweet potatoes.
  • Peel or leave skin on for added texture and nutrients.
  • Cut evenly to ensure uniform cooking.
  • Soak cut fries in cold water for 30 minutes to remove starch—this step is key for maximum crispiness.

Ingredients List

  • 2 large sweet potatoes, peeled and cut into thin fries
  • 1 tablespoon olive oil (or avocado oil)
  • 1/2 teaspoon sea salt
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon smoked paprika
  • 1/4 teaspoon black pepper
  • Optional: 1/2 teaspoon cornstarch for extra crisp

Flavor Variations

  • For heat: 1/4 teaspoon cayenne or chili powder
  • For sweet-savory: 1/2 teaspoon cinnamon + pinch of brown sugar
  • For herby: Add 1/2 teaspoon dried rosemary or thyme

Step-by-Step Directions

  1. Prep the Sweet Potatoes
    Wash, peel (optional), and cut into 1/4-inch thick fries.
  2. Soak in Water
    Soak the fries in cold water for at least 30 minutes. Drain and pat completely dry.
  3. Season the Fries
    In a bowl, toss the fries with olive oil and seasonings. Optionally, add cornstarch for extra crisp.
  4. Preheat the Air Fryer
    Set the air fryer to 375°F (190°C) and preheat for 3–5 minutes.
  5. Cook in Batches
    Arrange fries in a single layer. Avoid overcrowding.
  6. Air Fry the Fries
    Cook for 12–15 minutes, shaking the basket halfway through. Add 2–3 more minutes if needed for extra crispness.
  7. Cool Slightly Before Serving
    Let fries sit for 2–3 minutes to firm up their crisp.

Tips and Variations

  • Don’t skip the soaking step.
  • Rotate fries or shake halfway to ensure even browning.
  • Use parchment paper with holes if fries stick to your basket.
  • Try sweet potato wedges or shoestring cuts for variation.

Serving & Pairing

Serving Suggestions

Crispy Air Fried Sweet Potato Fries shine on their own but elevate any meal. Serve hot with one or more of the following:

  • Homemade garlic aioli
  • Chipotle mayo
  • Avocado ranch
  • Honey mustard
  • Sriracha ketchup

Common Mistakes to Avoid & How to Perfect the Recipe

Mistakes

  • Overcrowding the basket: Leads to soggy fries.
