FAQs

Can I use fresh tomatoes instead of canned?

Yes, fresh tomatoes can be used, but canned San Marzano tomatoes add a consistent, rich flavor and texture that enhances the soup.

How do I make the soup thicker?

Simmer the soup uncovered for a longer time to reduce liquid, or add a small amount of tomato paste during cooking to thicken and intensify flavor.

Mini Croutons

  • Small pieces of bread, cut into small cubes

  • Diced garlic (to taste)
  • Basil (fresh, chopped, to taste)

Instructions

  1. Preheat Oven: Set your oven to 375°F (190°C) to prepare for roasting the tomatoes.
  2. Prepare Tomatoes: Arrange the tomato halves cut side up on a baking sheet. Drizzle them with olive oil and sprinkle with kosher salt and black pepper for seasoning.
  3. Roast Tomatoes: Roast the tomatoes in the preheated oven for 1 hour until they are tender and slightly caramelized. Remove from the oven and set aside.

  5. Add Aromatics: Stir in the minced garlic, fresh thyme, salt, and black pepper. Continue to sauté for another minute to release the aromas.
