Instructions
Preheat oven to 350°F. Slice the top off the garlic head, place cut side down on a baking sheet with tomatoes, onion, thyme, olive oil, salt, and pepper. Toss and roast for 30-35 minutes.
Let garlic cool slightly, then squeeze out cloves. Transfer roasted vegetables to a blender, add garlic, and blend until smooth.
Pour in vegetable broth and creme fraiche, blend again until creamy. Adjust seasoning as needed.
Serve the soup in bowls, drizzled with extra olive oil and garnished with creme fraiche or sour cream.
Notes
For a richer flavor, roast the garlic longer or add fresh basil before serving.
