08 - Serve hot, drizzled with cream and garnished with fresh basil leaves and croutons or toasted bread if desired.

# Expert Suggestions:

01 -
  • Roasting the tomatoes transforms them into concentrated sweetness, so you taste pure tomato flavor without any tinny aftertaste.
  • It tastes restaurant-quality but actually comes together in under an hour with minimal hands-on time.
  • The whole kitchen smells incredible while it cooks, and somehow that's half the magic.
02 -
  • Don't use watery, pale tomatoes expecting magic—roasting concentrates what's already there, so mediocre tomatoes just become mediocre soup, while ripe tomatoes become extraordinary.
  • Tasting and adjusting at the end matters more than following exact measurements; sometimes tomatoes are naturally sweeter or more acidic, and only your palate knows what balance feels right.
03 -
  • Don't skip the parchment paper on your baking sheet—it prevents sticking and makes cleanup feel effortless.
  • If your blender is powerful enough, skip straining entirely and embrace the slight body the soup naturally has.
