How to Make Butternut Squash Soup with Roasted Vegetables

1. Preheat the oven – Set to 400°F (200°C) and line a baking sheet with parchment paper.
2. Prepare vegetables – Toss cubed butternut squash, sweet potatoes, onion, and garlic with olive oil, salt, and pepper. Spread in an even layer.
3. Roast until tender – Bake for 25–30 minutes, stirring halfway through, until vegetables are soft and caramelized at the edges.
4. Simmer with broth – Transfer roasted vegetables to a large pot, add vegetable broth and cinnamon, then simmer for 10 minutes to blend flavors.
