Ingredients

Scale
  • 1 tablespoon olive oil
  • 1 small yellow onion, diced
  • 4 cloves garlic, minced
  • 1 pound ground Italian sausage
  • 1 teaspoon Italian seasoning
  • ½ teaspoon red pepper flakes (optional)
  • ¼ teaspoon salt
  • 6 cups chicken broth
  • 10 lasagna noodles, broken into bite-sized pieces
  • 1 cup heavy cream
  • 4 ounces cream cheese, softened to room temperature
  • 2 cups fresh spinach, chopped
  • 1½ cups shredded mozzarella cheese
  • ½ cup grated Parmesan cheese
  • Fresh basil, for garnish

Instructions

  1. Heat olive oil in a large pot over medium heat. Add onion and saute for 3-4 minutes, stirring occasionally, until translucent.
  2. Add garlic and cook for 30 seconds until fragrant, stirring constantly.
  3. Add ground Italian sausage, breaking it up with a spoon. Cook for 8-10 minutes, stirring and breaking up meat, until browned and no pink remains.
  4. Season with Italian seasoning, red pepper flakes if using, and salt. Stir to combine.
  5. Pour in chicken broth and bring to a rolling boil over high heat.
  6. Stir in broken lasagna noodles and cook for 8-10 minutes, stirring every 2-3 minutes, until noodles are tender but still slightly firm (al dente).
  7. Reduce heat to low. Cut cream cheese into 1-inch cubes and stir continuously for about 2 minutes until completely melted and smooth.
  8. Add heavy cream and chopped spinach. Simmer for 2-3 minutes until spinach wilts.
  9. Turn off heat and stir in mozzarella and Parmesan cheeses until melted.
  10. Let soup rest for 3-5 minutes to allow cheese to fully incorporate and soup to thicken slightly. Garnish with fresh basil before serving.

Notes

  • Don’t overcook pasta as it will continue to absorb liquid. Break lasagna noodles into bite-sized pieces for easier eating.
  • Soften cream cheese to room temperature before adding for smoother melting. Use quality Italian sausage for optimal flavor.
  • Add spinach just before serving for best color and texture. Stir every 2-3 minutes while cooking noodles to prevent sticking.
  • If soup becomes too thick, add chicken broth or cream ¼ cup at a time until desired consistency is reached.
