Preheat oven to 200℃ and line a tray with baking paper.
Wash and cut carrots. Toss in 2 tbsp of the olive oil and sprinkle with sea salt.
Arrange the chopped carrots flat on the tray and roast for about 40 minutes until tender when pierced with a knife.
Remove from the oven and set aside to cool for 10 minutes.
Place the coked carrots in a bowl and blend them with a handheld mixer, together with the tahini and garlic until the mixture is a smooth puree.
Season with salt and pepper to taste. Add more garlic if you wish.
Serve in a shallow bowl, drizzled with the remaining olive oil and toasted pumpkin seeds.
If not using immediately, refrigerate and bring to room temperature before serving.
