Creating Zuppa Toscana is straightforward if you follow these simple steps:

1. Sauté the Sausage: In a large pot, heat a drizzle of olive oil over medium heat. Add the Italian sausage and cook until browned, breaking it apart with a spatula as it cooks.
2. Add Onions and Garlic: Once the sausage is browned, add the chopped onions and minced garlic. Sauté for about 3-5 minutes until the onions become translucent.
3. Add Potatoes: Stir in the sliced potatoes, mixing them well with the sausage and onion mixture.
4. Pour in Chicken Broth: Add the chicken broth to the pot, ensuring all ingredients are submerged. Bring to a boil, then reduce the heat to a simmer.
5. Cook the Potatoes: Allow the soup to simmer for about 15-20 minutes, or until the potatoes are tender.
6. Incorporate Kale: Once the potatoes are cooked, add the chopped kale to the pot. Allow it to wilt for about 3-5 minutes.
7. Add Cream: Pour in the heavy cream, stirring well to combine. Let the soup simmer for an additional 5 minutes.
8. Season: Taste and adjust the seasoning with salt, pepper, and red pepper flakes if desired.
9. Serve: Remove from heat and ladle the soup into bowls. Top with freshly grated Parmesan cheese if preferred.
