Heat a large pot or Dutch oven over medium-high heat. Add beef. Cook, breaking beef into small pieces with a wooden spoon, until browned and cooked through, about 6 minutes. Add salt.
Reduce heat to medium and add marinara sauce to pot with beef. Fill empty marinara jar with water (approx. 3 cups) and add to the pot as well. Stir to combine. Add pasta and stir again.
Bring pasta and sauce to a simmer (just barely bubbling). Cook, for 15 minutes, stirring frequently to ensure pasta does not stick to the bottom. Add 1 more cup water and continue cooking, stirring frequently, until pasta is tender, about 15 minutes more.
Garnish with parmesan and fresh basil. Serve immediately.
