Making Creamy Tuscan Ravioli Soup is straightforward when you follow these simple steps:

1. Sauté Aromatics: In a large pot, heat olive oil over medium heat. Add the diced onion and sauté until translucent, about 5 minutes. Add minced garlic and sauté for an additional minute, until fragrant.
2. Add Broth and Tomatoes: Pour in the vegetable or chicken broth and add the undrained diced tomatoes. Stir well to combine.
3. Season the Mixture: Add Italian seasoning and season with salt and pepper to taste. Bring the mixture to a simmer.
4. Cook the Ravioli: Once simmering, add the ravioli to the pot. Cook according to package directions, usually around 5-7 minutes, until the ravioli floats and is tender.
5. Incorporate Spinach: Stir in the fresh spinach and let it wilt for about 2-3 minutes.
6. Add Cream: Reduce the heat to low and pour in the heavy cream. Stir gently to combine, ensuring the soup is heated through but not boiling.
7. Adjust Seasoning: Taste and adjust the seasoning with more salt and pepper if necessary.
8. Serve Hot: Ladle the soup into bowls, and top with grated Parmesan cheese and fresh basil for garnish.

These steps will guide you in creating a comforting bowl of Creamy Tuscan Ravioli Soup with ease.
