Ingredients
Method
Step-by-Step
- Prepare the onion, carrots, celery, garlic, and cabbage. Remove the cabbage core and chop the leaves into bite-size pieces so they cook evenly.
- Heat the olive oil in a large Dutch oven or soup pot over medium heat. Add the onion, carrots, celery, kosher salt, and black pepper, then cook for 6–8 minutes, stirring occasionally, until the vegetables begin to soften.
- Add the minced garlic, tomato paste, Italian seasoning, and optional red-pepper flakes. Cook for 30–60 seconds, stirring constantly, until the garlic is fragrant and the tomato paste is blended into the vegetables.
- Stir in the diced tomatoes, broth, and chopped cabbage. Bring the mixture to a boil, then reduce the heat, partially cover the pot, and simmer for 20–25 minutes, or until the cabbage and carrots are tender.
- Stir in the drained and rinsed white beans, if using. Simmer for another 5 minutes so the beans warm through while keeping their shape.
- Remove the soup from the heat and stir in the red-wine vinegar or fresh lemon juice. Taste and adjust the salt and pepper, then garnish with fresh parsley and serve hot.
Notes
Sauté the aromatic vegetables before adding the broth for deeper flavor. Add beans near the end so they stay intact. Refrigerate leftovers in a covered container and reheat gently on the stovetop or in the microwave.
