Ingredients
Method
- Preheat oven to 425°F. Halve tomatoes and cut onion into wedges. Drizzle with olive oil, season, and roast 45-60 minutes until golden.
- In a large pot, melt butter over medium heat. Sauté minced garlic 30-60 seconds until fragrant.
- Add roasted tomatoes, onions, and juices to pot. Stir in broth and fresh basil.
- Blend with immersion blender until smooth. Strain for extra silky texture if desired.
- Add thyme sprig and heavy cream. Simmer 30 minutes, remove thyme, season with salt and pepper. Stir in a pinch of baking soda if desired.
Notes
Roasting develops up to 60% of this soup’s flavor complexity—don’t skip this step. Add cream after simmering to prevent curdling.
