In a large, heavy-bottomed stock pot set over medium-low heat, add the olive oil, garlic and a pinch of kosher salt. Cook, stirring, until the garlic is golden and fragrant, about 2 minutes.
Add the tomato paste and cook, stirring, until caramelized, about 1 minute.
Increase the heat to medium then add the ground beef, Italian seasonings and 1/2 teaspoon kosher salt. Cook, breaking apart the meat with a spatula, until it is no longer pink, about 5 minutes.
Stir in the marinara sauce, beef broth, Worcestershire and sugar.
Increase the heat to medium-high then stir in the pasta. Bring the mixture to a boil, cover the pot, then reduce it to a simmer. Cook until the pasta is al dente, stirring the pasta every 5 minutes to release any noodles from the bottom of the pot that may be sticking, about 25 minutes.
Uncover the pot then taste and season the pasta with additional salt or sugar, as desired. Serve the pasta topped with grated Parmesan cheese.
