Instructions
To Make the Croutons
Preheat oven to 400˚F.
Add bread cubes to a medium bowl; drizzle with olive oil and toss to coat. Spread cubes in a single layer on a baking sheet and season to taste with kosher salt. Bake 15 to 20 minutes until golden and crisp. Remove from oven and set aside.
For the Bisque
Meanwhile, heat butter and olive oil in a soup pot over medium heat until sizzling. Add onion, carrot, celery and garlic; cook and stir until onion is softened and translucent, about 5 minutes. Add tomatoes, water, oregano, crushed red pepper, salt and pepper. Stir and bring to boil; reduce heat and simmer 15 minutes.
To finish the soup, remove from heat and stir in fresh basil leaves; blend in the pan with an immersion blender or blend in batches in a traditional blender. (Important note: Blending hot liquids in a traditional blender will blow the lid off which will make a mess and could burn you. Instead, use a towel to cover the top of of the pitcher while blending instead of the lid.)
Return blended soup to pan and stir in heavy cream; season to taste with salt and pepper. Reheat to simmer if needed.
Ladle hot soup in to bowls and top with croutons. Garnish with fresh basil leaves if desired and serve.
