Start by preheating the oven to 200°C fan.
Add the pumpkin, carrots and onion to a large enough mixing bowl. Drizzle with olive oil, salt, paprika and a good crack of black pepper. Toss well to coat.
Transfer to a large parchment-lined tray. Wrap the garlic cloves in aluminium foil and find a cosy spot for it on the tray.
Roast for 20 minutes until everything is tender and caramelised. Remove from the oven and set aside.
While the veggies are cooling, put 1/2 litre of vegetable stock (or water) to boil in a large pot. Add a pinch more salt.
Once it comes to boil, reduce the heat (to medium/ medium low) and tip in the roasted veggies & garlic, taking care to also pour in any leftover oil from the baking tray.
Give it a good stir and let it simmer for 5-7 minutes or so, before removing from heat.
Once cooled down, blitz everything until smooth. Serve garnished with a sprig of basil or toasted pumpkin seeds.
