Serves: 6
Prep time: 15 minutes
Cook time: 30 minutes
Difficulty: moderate
Featured appliance: Philips ‘4000 Series’ Stacked Dual Basket Air Fryer. Cook two dishes at once with stacked baskets, smart tech and a compact design.
Ingredients
3 large sweet potatoes, peeled and thinly sliced (use a mandoline for even slices)
2 tbsp cream
1 cup Gruyére cheese, finely grated
1 tsp rosemary, finely chopped (and extra for garnish!)
Olive oil spray
Flaky salt, for seasoning
Extra rosemary sprigs, to garnish
Method for Gruyére and Sweet Potato Stacks
1. Preheat the air fryer to 180°C.
2. Thinly slice sweet potatoes and pat dry with paper towel.
3. In a large bowl, toss slices with cream, Gruyére, rosemary, and a pinch of salt.
4. Layer slices into small stacks (about 6–7 cm high), pressing lightly so they hold together. Secure with toothpicks if needed.
5. Arrange stacks in the air fryer basket. Spray with olive oil and cook for 15 minutes, until golden at the edges and tender in the centre.
6. Remove toothpicks. Transfer stacks to a serving platter, sprinkle with flaky salt, and garnish each with a rosemary sprig.
Handy Hints for your Gruyére and Sweet Potato Stacks
- Use orange and purple sweet potatoes together for colour contrast.
- Chill slices in iced water before layering for extra crisp edges.
- These can be assembled a few hours ahead and cooked just before serving.
