Ingredients
Method
- Heat the oil in a large soup pot or Dutch oven over medium heat.
- Add the onion, carrots, and celery. Cook, stirring occasionally, until the vegetables are tender and the onions are lightly browned.
- Stir in the garlic and cook for one more minute. Add the tomato paste and cook for 20 to 30 seconds. Pour in the canned tomatoes, broth, salt, and pepper. Scrape any browned bits from the bottom of the pot.
- Bring the pot to a boil. Cover, reduce heat to a simmer, and cook until the vegetables are very soft, 15 to 20 minutes.
- Stir in the spinach and let it wilt for one to two minutes. Then, add the yogurt and brown sugar, if desired.
- Puree the soup directly in the pot with an immersion blender until smooth. Alternatively, carefully transfer the soup to a regular blender, process in batches, and return it to the pot to reheat.
- Taste the blended soup and adjust the seasoning with salt and pepper. Ladle into bowls and serve.
Notes
This soup is great served with the classic grilled cheese, any kind of bread, toast, or crackers. We like to make cheesy garlic bread with butter, garlic powder, and any kind of shredded cheese toasted on sliced bread.
You can garnish soup with grated parmesan, a sprinkle of shredded cheese, fresh basil, or sliced fresh spinach leaves.
