Creating Zuppa Toscana Soup can be straightforward when you follow these easy steps:

1. Brown the Sausage: In a large pot or Dutch oven, heat a splash of olive oil over medium heat. Add the Italian sausage, breaking it apart with a spoon. Cook until browned, about 5-7 minutes.
2. Sauté the Vegetables: Add the chopped onion and minced garlic to the pot, cooking until the onion becomes translucent, around 3-5 minutes.
3. Add Broth and Potatoes: Pour in the chicken broth and add the thinly sliced potatoes. Increase the heat and bring the mixture to a simmer.
4. Simmer: Let the ingredients cook together for about 20 minutes, or until the potatoes are tender.
5. Incorporate Kale: Stir in the chopped kale and let it wilt in the soup for about 5 minutes.
6. Creamy Finish: Reduce the heat to low, and slowly pour in the heavy cream. Stir well to combine, allowing it to heat without boiling.
7. Season: Taste the soup and adjust the seasoning with salt, pepper, and red pepper flakes according to your preference.
8. Serve: Ladle the Zuppa Toscana Soup into bowls and enjoy the nourishment it offers with each delightful bite.
