Preheat the oven to 400°F (200°C). Place the diced butternut squash, roughly chopped onion, and halved garlic head facing down on a baking sheet lined with parchment paper. Drizzle with olive oil and toss to coat.
Roast in the oven for 25-30 minutes or until tender and lightly browned. Add the roasted vegetables and vegetable broth to the pot. Bring to a boil, reduce the heat, and let simmer for 10-15 minutes. Stir from time to time.
Blend. Peel the garlic. Use an immersion blender or transfer the soup to a blender and purée until smooth or has your favorite texture—season with salt and pepper to taste. Serve hot with olive oil and fried sage leaves if you'd like.
