  • Vanilla Extract1.5 tsp
  • Milk1.5 cup

Instructions

  1. 1

    Heat oven to 425°F (220°C). Peel 2 large sweet potatoes (or scrub well — skin is edible). Cut into ½-inch wide fries (uniform size matters).

  2. 2

    Soak the cut fries in cold water for 30 minutes. This removes excess starch. Drain and pat very dry — wet fries don't crisp.

  3. 3

    In a large bowl, toss the dry fries with 1 tablespoon of cornstarch. The cornstarch creates the crispy exterior.

  4. 4

    Add 2 tablespoons of olive oil, 1 teaspoon salt, 1 teaspoon paprika, ½ teaspoon garlic powder, ½ teaspoon black pepper, ¼ teaspoon cayenne (optional). Toss to coat completely.

  5. 5

    Spread on a parchment-lined baking sheet in a single layer with space between fries. Use two sheets if needed — crowded fries steam.

  6. 6

    Bake 30-35 minutes, flipping halfway, until deeply golden and crispy. Sprinkle with extra salt while hot. Serve immediately with sriracha mayo, ranch, or honey mustard.

💡 Expert Tips

  • 1.Soak then dry. Removes starch and surface moisture. Both matter.
  • 2.Cornstarch coating. The secret for crispy oven fries.
  • 3.Single layer with space. Crowded fries steam, don't crisp.
  • 4.Don't move during first half of baking. The crust forms when undisturbed.

🔬 Why It Works

Crispy sweet potato fries depend on three techniques: soak-and-dry (removes starch and moisture), cornstarch coating (creates crispy exterior), and proper spacing (allows Maillard browning rather than steaming). The high oven temperature (425°F) creates the crispy texture; lower temperatures give limp soft fries.

Frequently Asked Questions

Why are sweet potato fries always soggy?
Most recipes skip the soak-dry-cornstarch combination. With those three steps, you get crispy fries that hold up.
Can I deep-fry?
Yes — fry at 350°F for 3-4 minutes per batch. Crispier but more work and oil.
Best dipping?
Sriracha mayo, honey mustard, ranch, chipotle aioli, garlic aioli. Or eat plain — they're sweet enough.
Spice variations?
Cinnamon-sugar (sweet version), za'atar, taco seasoning, jerk seasoning. The neutral sweet potato takes well to many spices.
