Cook turkey: In a large pot over medium heat, add ground turkey, onions, and garlic. Cook until the turkey is browned and onions are transparent, about 7-10 minutes.
Add tomatoes and broth: Stir in the crushed tomatoes and broth, mixing thoroughly. Bring the mixture to a simmer, allowing the flavors to blend for about 10 minutes.
Add noodles: Break the lasagna noodles into smaller pieces and add them to the pot. Cook until the noodles are al dente, which usually takes about 10-12 minutes.
Mix in seasoning: Stir in Italian seasoning and salt to taste. Adjust flavors according to your preference, enhancing the dish's character.
Incorporate ricotta: Remove the pot from heat and stir in the ricotta cheese until combined. This will add creaminess and take the soup to a comforting level.
Serve: Ladle the soup into bowls and top with mozzarella cheese and fresh basil. Let the cheese melt slightly before enjoying.
