Steps

1. Roast vegetables: Heat oven to 400º. On a large rimmed baking sheet, toss all vegetables with oil, salt and pepper. Roast in the hot oven until tender, about 25-30 minutes.
2. Prepare soup: Once vegetables are done, melt butter in a large pot over medium heat. Add cumin and thyme and cook for 1-2 minutes, until fragrant. Add roasted vegetables, then add chicken broth. Simmer for 10 minutes on low heat.
3. Finish: Blend soup until creamy using an immersion blender. Add cream to taste, then simmer for another few minutes. Adjust seasoning and cream to taste before serving.
