Let’s dive into the cooking process with these easy-to-follow instructions:

1. Start by heating olive oil in a large pot over medium heat. Add the Italian sausage, breaking it into small pieces with a wooden spoon. Cook until browned, about 5-7 minutes. Remove the sausage from the pot and set aside.
2. In the same pot, add the diced onion and minced garlic. Sauté until the onion becomes translucent and fragrant, approximately 3-4 minutes.
3. Pour in the chicken broth and bring to a gentle simmer. Add the diced potatoes and cook until they are fork-tender, around 15-20 minutes.
4. Stir in the heavy cream, cooked sausage, salt, pepper, oregano, and red pepper flakes. Let the soup simmer for an additional 5 minutes, allowing the flavors to meld together.
5. Finally, add the chopped kale, stirring until wilted but still vibrant green, about 2-3 minutes.
6. Serve hot, garnished with freshly grated Parmesan cheese for an extra touch of indulgence.

This soup is a testament to the lessons I learned from my abuela: taste as you go, and don’t be afraid to adjust the spices to suit your palate. Cooking is an art, and every dish is a canvas.
