Follow these simple steps to make your Creamy Parmesan Italian Sausage Ditalini Soup:

1. Cook the Sausage: In a large pot, heat a drizzle of olive oil over medium heat. Add the Italian sausage, breaking it up with a spoon. Cook until browned, about 5-7 minutes. Drain excess fat if necessary.

2. Sauté the Vegetables: Add the diced onion and minced garlic to the pot. Sauté until the onion becomes translucent, about 3-4 minutes.

3. Add the Broth and Tomatoes: Pour in the chicken broth and add the diced tomatoes. Stir to combine and bring the mixture to a simmer.

4. Cook the Pasta: Once simmering, add the ditalini pasta and Italian seasoning. Cook according to the pasta package instructions, usually around 8-10 minutes until al dente.

5. Incorporate the Cream: Stir in the heavy cream and allow the soup to heat through for about 2-3 minutes.

6. Add Spinach and Cheese: If using, add the baby spinach and stir until wilted. Then mix in the grated Parmesan cheese, stirring until melted and creamy.

7. Season: Taste the soup, adding salt and pepper as needed to enhance the flavor.

8. Serve: Remove from heat, and let it cool slightly before ladling into bowls.
