Creating Roasted Vegetable Soup is straightforward if you follow these easy steps:

1. Preheat Oven: Preheat your oven to 425°F (220°C).
2. Prep Vegetables: Wash, peel, and chop your selected vegetables into bite-sized pieces.
3. Toss with Olive Oil: In a large bowl, combine the chopped vegetables with olive oil, salt, pepper, thyme, and basil.
4. Roast Vegetables: Spread the seasoned vegetables on a baking sheet in a single layer. Roast in the preheated oven for 20-25 minutes, or until tender and slightly charred.

7. Blend the Soup: Bring the mixture to a simmer and cook for 5-10 minutes. Then, use an immersion blender to blend until smooth or until the desired consistency is reached.
8. Adjust Seasoning: Taste the soup and adjust seasoning with salt, pepper, or balsamic vinegar if desired.
9. Serve Warm: Ladle the hot soup into bowls for serving.
