Making Zuppa Toscana is a straightforward process. Just follow these simple steps to create this comforting masterpiece:

1. Cook the Sausage: In a large pot, heat a drizzle of olive oil over medium heat. Add the Italian sausage and cook until browned. Break it up with a spoon as it cooks.
2. Add Onions and Garlic: Once the sausage is browned, add the diced onion and minced garlic. Sauté until the onion becomes translucent, about 3-5 minutes.
3. Pour in Chicken Broth: Stir in the chicken broth, scraping up any bits stuck to the bottom of the pot. Bring the broth to a boil.
4. Add Potatoes: Add the sliced potatoes to the boiling broth and reduce heat to simmer. Cook for about 15-20 minutes, or until the potatoes are tender.
5. Add Kale: Stir in the chopped kale and cook for an additional 5 minutes until it wilts.
6. Incorporate Cream: Slowly pour in the heavy cream, stirring to combine. Adjust the consistency by adding more broth or cream as needed.
7. Season: Enhance the flavors with salt, pepper, and red pepper flakes if desired. Taste and adjust seasonings as needed.
8. Serve Hot: Ladle the soup into bowls and serve immediately.
