Stir in the onion, carrots and garlic and cook until softened, 5 to 7 minutes. Stir in 2 cups water, the chicken broth and tomatoes; cover and bring to a boil. Add the pasta and cook until al dente, about 15 minutes. Stir in the basil and season with salt and pepper.
Serve the stoup in bowls and dollop with the ricotta. Pass the parmigiano-reggiano at the table.
