In a large pot, heat a splash of olive oil over medium heat. Add 1 lb ground turkey, 1 chopped onion, and 3 minced garlic cloves. Cook until the turkey is browned and the onion is translucent, approximately 5-7 minutes.
Next, pour in 4 cups of chicken broth and 2 cups heavy cream. Stir the mixture well to combine.
Add 12 broken lasagna noodles into the pot. You can break them into halves or thirds, depending on your preference. Bring the mixture to a gentle boil, then cook until the noodles are tender, about 10-12 minutes.
Season your soup with salt and pepper to taste, and sprinkle in 1 tsp Italian seasoning.
Once the noodles are cooked, stir in 2 cups ricotta cheese and half of the 2 cups shredded mozzarella cheese. Cook until the cheese has melted and blended into the soup.
Serve the soup hot, garnished with the remaining mozzarella, 1 cup grated Parmesan cheese, and a sprinkle of fresh basil if desired.
