Preheat the oven: Heat your oven to 200°C (fan 180°C) / 400°F / Gas Mark 6.
Prepare the squash: Spread the diced squash on a large baking tray. Drizzle over the olive oil, sprinkle with thyme, salt, and pepper, then toss with your hands to coat evenly.
Roast the squash: Roast for 30–40 minutes, turning once with a metal spatula halfway through, until golden and tender.
Serve hot: Taste for seasoning, then serve hot as a side with your favourite main.
