Break the sausage into small chunks and cook over medium-high heat until deeply browned (5-7 minutes), then remove before building your broth base—this creates fond that adds incredible depth to your soup.

Stir in tortellini only during the last 4-5 minutes of cooking; adding it too early causes the pasta to absorb excess broth and become mushy, while late addition keeps it perfectly tender with intact cheese filling.

After browning sausage, reserve 1-2 tablespoons of the rendered fat and sauté minced garlic for 30-45 seconds until fragrant before adding onions—this technique intensifies garlic flavor and prevents bitterness.

Before stirring heavy cream into the hot broth, ladle a cup of hot soup into the cream while whisking constantly, then add the mixture back—this prevents curdling and ensures a silky, luxurious texture.

Add fresh spinach leaves in the final minute after all other ingredients are cooked; they'll wilt quickly while retaining vibrant color and nutritional value, rather than becoming dark and bitter if cooked longer.
