Naturally vegan, gluten-free, and packed with flavor, it’s the healthy dinner upgrade you’ll make on repeat.
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
- Preheat oven to 200°C (392°F) fan-forced / 220°C (428°F) conventional. Line a large baking tray with parchment paper.
- Wash the sweet potatoes thoroughly and pat completely dry. Leave the skin on for extra crispiness and nutrients.
- 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.
- Gently fan out the slices slightly. Transfer to the prepared tray.
- 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.
- Bake for 35–45 minutes until the edges are golden and crispy and a knife slides easily through the thickest part.
- 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.
- 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.
- 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.
- Scatter the caramelized walnuts on top and finish with a sprinkle of fresh parsley.
