Step 1

Preheat oven to 200°C (180°C fan-forced). Line three oven trays with baking paper.

Step 2

Using a spiraliser or julienne attachment on a mandoline or V-slicer, cut pumpkin into long thin strips (see tips). Combine pumpkin and oil in a large bowl; season.

Step 3

Spread pumpkin strips in a single layer between two trays. Roast for 12 minutes or until just tender; cover to keep warm. If using thinner noodles, you will need to reduce the cooking time. Meanwhile, place walnuts and pepitas on the third tray; roast for 5 minutes or until fragrant.

Step 4

Cook bacon in a medium frying pan over medium heat, stirring occasionally, for 5 minutes or until browned. Add cream, milk and ½ cup of the pecorino; bring to the boil. Simmer for 5 minutes or until sauce thickens. Season to taste.

Step 5

Carefully transfer pumpkin to a large shallow bowl. Pour sauce over pumpkin; top with roasted nut mixture, remaining pecorino and chives. Season with freshly ground black pepper. Serve immediately.
