Ingredients (serves 3–4)

For the Sweet Potato Fans

  • 3 large sweet potatoes (about 250–300 g / 9–10 oz each)
  • 2 tablespoons olive oil
  • 1 teaspoon fine salt
  • ½ teaspoon freshly ground black pepper
  • 1 teaspoon sweet paprika powder
  • 1 teaspoon garlic powder

For the Chili-Maple Glaze & Candied Walnuts

  • 3 tablespoons pure maple syrup
  • 1 tablespoon soy sauce (or tamari for gluten-free)
  • 1 teaspoon chili sauce (sriracha or your favorite hot sauce, adjust to taste)
  • 1 teaspoon lemon juice
  • 1 teaspoon vegetable oil (or olive oil)
  • 50 g (½ cup) walnut halves or pieces
  • Fresh parsley, chopped (for garnish)

Step-by-Step Instructions

  1. Preheat oven to 200°C (392°F) fan-forced / 220°C (428°F) conventional. Line a large baking tray with parchment paper.
  2. Wash the sweet potatoes thoroughly and pat completely dry. Leave the skin on for extra crispiness and nutrients.
  3. Place one sweet potato on a cutting board. Lay two wooden spoons or chopsticks along both sides to act as guards. Slice the potato crosswise into 3–4 mm (⅛-inch) thin slices, cutting only until the knife hits the spoons – this keeps the base intact and creates the “fan” effect. Repeat with all potatoes.
  4. Gently fan out the slices slightly. Transfer to the prepared tray.
  5. In a small bowl, mix olive oil, salt, black pepper, sweet paprika, and garlic powder. Brush this mixture generously over every slice, getting into the crevices.
  6. Bake for 35–45 minutes until the edges are golden and crispy and a knife slides easily through the thickest part.
  7. While the potatoes roast, prepare the glaze: In a small non-stick pan over medium heat, combine maple syrup, soy sauce, chili sauce, lemon juice, and vegetable oil. Bring to a gentle simmer.
  8. Add the walnuts and cook, stirring constantly, for 2–3 minutes until the glaze thickens and coats the nuts beautifully. Remove from heat immediately to prevent burning.
  9. When the sweet potato fans are ready, remove from the oven and immediately spoon or brush the hot glaze over each one, letting it drip into the layers.
  10. Scatter the caramelized walnuts on top and finish with a sprinkle of fresh parsley.
