Here’s how to create the delightful Creamy Italian Meatball Soup in just a few straightforward steps:

1. Make the Meatballs: In a large bowl, combine the ground beef, ground Italian sausage, breadcrumbs, Parmesan cheese, egg, minced garlic, oregano, basil, salt, and pepper. Mix well until fully combined.

2. Form Meatballs: Shape the mixture into small meatballs, about 1 inch in diameter. Set aside on a plate.

3. Sauté the Vegetables: In a large pot, heat olive oil over medium heat. Add the diced onion and sauté until translucent, about 3-4 minutes.

4. Add Carrots and Tomatoes: Stir in the diced carrots and halved tomatoes, cooking for another 3 minutes.

5. Add Chicken Broth: Pour in the chicken broth and bring to a gentle boil.

6. Cook Meatballs: Gently add the meatballs to the pot. Allow them to simmer in the broth for about 15-20 minutes, until they are cooked through.

7. Stir in Spinach: Once the meatballs are fully cooked, stir in the chopped spinach, allowing it to wilt.

8. Add Cream: Pour in the heavy cream and mix gently. Allow the soup to simmer for another 2-3 minutes for the flavors to meld.

9. Taste and Season: Before serving, taste the soup and adjust seasoning with additional salt and pepper if necessary.

10. Serve Hot: Ladle the soup into bowls and serve immediately, garnished with extra Parmesan cheese if desired.
