In a large pot over medium-high heat, add the Italian sausage, breaking it apart as it cooks. Sauté for about 6-8 minutes until the sausage is browned and cooked through. Once browned, remove the sausage from the pot and set it aside, leaving the delicious drippings behind for the next step.

In the same pot, pour in a splash of olive oil if needed, and add the diced onion, carrot, and celery. Sauté the vegetables for 5-7 minutes or until they become tender and fragrant. Stir in the minced garlic and cook for an additional 1-2 minutes until the garlic releases its aroma, enhancing the flavors for your Creamy Parmesan Italian Sausage Ditalini Soup.

Pour in the chicken broth and diced tomatoes, stirring everything together. Bring the mixture to a gentle simmer while adding Italian seasoning, salt, and black pepper to taste. Allow this savory mixture to simmer uncovered for 10-15 minutes, allowing the flavors to meld beautifully and the vegetables to soften further.

Carefully stir in the uncooked ditalini pasta, ensuring it's submerged in the broth. Reduce the heat to medium-low and let the soup simmer for 10-12 minutes, stirring occasionally. Watch as the ditalini cooks through, filling your kitchen with the comforting aroma of the Creamy Parmesan Italian Sausage Ditalini Soup.

Once the pasta is tender, lower the heat further and stir in the heavy cream and grated Parmesan cheese. Continue to mix until the cheese has melted fully and the soup is creamy and smooth. Return the browned sausage to the pot and let everything simmer together for an additional 5 minutes to allow the flavors to combine.

As your Creamy Parmesan Italian Sausage Ditalini Soup reaches its final stage, garnish with freshly chopped parsley for a pop of color. Serve the soup hot, ideally paired with crusty bread for dipping.
