Creating the Best Tuscan White Bean Soup is simple and rewarding. Follow these steps for a perfect bowl of soup:

1. Prepare the Beans: Rinse and soak the dried white beans in water for 8 hours or overnight. Drain and set aside.
2. Sauté the Vegetables: In a large pot over medium heat, heat the olive oil. Add the diced onion, carrots, and celery. Sauté for about 5-7 minutes, until the vegetables soften.
3. Add Garlic and Herbs: Stir in the minced garlic, thyme, and rosemary. Cook for an additional minute until fragrant.
4. Combine Ingredients: Add the soaked white beans, vegetable broth, diced tomatoes (with juice), and bay leaf. Bring to a boil.
5. Simmer the Soup: Reduce heat to low and let the soup simmer uncovered for about 45-60 minutes, or until the beans are tender. Stir occasionally to prevent sticking.
6. Season: After the beans are cooked, add salt and pepper to taste. If using, stir in the kale or spinach and cook for an additional 5 minutes until wilted.
7. Serve: Remove the bay leaf. Ladle the soup into bowls and garnish with chopped parsley and grated Parmesan cheese, if desired.

With these straightforward instructions, you’ll have a wonderfully fragrant and filling soup ready to enjoy!
