Classic tomato soup
- 2 tbsp extra-virgin olive oil
- 1 brown onion
- ½ teaspoon fine sea salt
- 2 tbsp tomato paste
- 1 400g tin diced tomatoes
- 2 cups vegetable broth
- ½ cup cooked cannellini bean rinsed and drained
- 2 tbsp unsalted butter cut into a few pieces
- 1 teaspoon coconut sugar or brown sugar to taste
- Salt and pepper to taste
- In a Dutch oven or soup pot, warm the olive oil over medium heat until shimmering. Add the onion and salt and cook, stirring occasionally, until the onions are tender and turning translucent, 7 to 10 minutes. Add the tomato paste and cook, stirring constantly, until fragrant, about 30 seconds.
- Add the tomatoes and vegetable broth and stir to combine. Increase the heat to medium-high, and bring the mixture to a simmer. Cook for 30 minutes, reducing the heat as necessary to maintain a gentle simmer, and stirring occasionally.
- Remove the pot from the heat and let it cool for a few minutes. Carefully transfer the mixture to a blender, being sure not to fill past the maximum fill line (blend in batches if necessary). Add the beans, butter, sugar, and several twists of black pepper. Securely fasten the lid and blend the soup until smooth, being careful to avoid hot steam escaping from the lid.
- Since canned tomatoes vary in flavor, I always end up tinkering with this soup a bit at the end. Taste and, if necessary, add a little more sugar (to balance out the acidity of the tomatoes), pepper, and salt (I usually add another ¼ to ½ teaspoon).
- If you’re adding basil, add it now. Briefly blend again, and serve hot. This soup keeps well for up to four days or so. You can freeze leftovers for up to 3 months.
