In a large pot set over medium-low heat, add the olive oil then add the sausage and cook it, breaking it apart into pieces, until it is no longer pink.
Add the garlic and cook, stirring, until it is golden brown, 2 to 3 minutes.
Add the marinara sauce, stirring to combine, then stir in 2 cups of water and the pasta.
Bring the mixture to a boil, reduce it to a simmer then cover the pot and continue cooking until the pasta is al dente, 12 to 15 minutes.
Serve the pasta topped with Parmesan cheese and fresh basil.
