Equipment

  • 1 large pot or Dutch oven
  • 1 wooden spoon
  • 1 ladle
  • 1 blender (optional for smoother texture)
  • 1 cutting board

Ingredients
  

  • 2 tablespoons olive oil
  • 2 large onions, thinly sliced
  • 3 cloves garlic, minced
  • 4 cups ripe tomatoes, chopped (or 28 oz canned tomatoes)
  • 4 cups vegetable or chicken broth
  • 1 teaspoon sugar
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 1 tablespoon balsamic vinegar
  • Fresh basil leaves for garnish (optional)

Instructions
 

  • Heat the olive oil in a large pot over medium heat. Add the sliced onions and cook, stirring occasionally, for about 15 minutes, until they are soft and begin to caramelize.
  • Add the minced garlic and cook for another 2 minutes, making sure it doesn’t burn.
  • Stir in the chopped tomatoes, sugar, salt, and black pepper. Cook for about 5 minutes, allowing the flavors to meld and the tomatoes to soften.
  • Pour in the vegetable or chicken broth and bring the mixture to a boil. Reduce the heat and let it simmer for an additional 10 minutes.
  • If a smoother texture is desired, use an immersion blender to puree the soup to your liking. Alternatively, you can transfer it to a blender in batches.
  • Stir in the balsamic vinegar and adjust the seasoning if necessary.
  • Serve hot, garnished with fresh basil leaves if desired.
  • For added richness, consider drizzling a bit of cream or olive oil on top before serving.
