Place the diced butternut squash on a baking tray. Drizzle with Tenuta Marmorelle ZERO Extra Virgin Olive Oil, season with salt and black pepper and add the sage leaves. Toss well to coat.
Roast for 25–30 minutes, turning halfway, until golden and tender.
Gradually add the vegetable stock, one ladleful at a time, stirring regularly and allowing each addition to absorb before adding more. Continue until the risotto is creamy and reaches your desired consistency. Add more or less stock as needed.
Once cooked, add the butter and stir until melted and fully incorporated.
Stir in the grated Parmesan until smooth and creamy. If needed, add a little more boiling water or stock to reach your preferred consistency.
Gently stir through the roasted butternut squash and roasted sage leaves, reserving a little for the top.
Serve with the remaining roasted butternut squash and sage, finished with freshly ground black pepper
