Heat a large pot of salted water until it boils, then cook the pasta following the package instructions until al dente. Drain the pasta using a colander and set it aside.
In a saucepan of medium size, heat the olive oil over medium-high heat. Add the chopped onions and cook them until they turn translucent through sautéing.
Add the minced garlic and sauté for an additional minute until fragrant.
Stir in the ground beef and cook until it's browned and cooked through. Break up the meat with a wooden spoon as it cooks.
Add the dried oregano, dried basil, crushed tomatoes, red pepper flakes (if using), salt, and black pepper into the mixture. Stir everything together, bring it to a simmer, and let it cook for 15-20 minutes to allow the flavors to meld together.
Add the cooked pasta to the sauce, tossing it gently until all the pasta is coated with the meaty marinara sauce.
Serve the Tuscani Meaty Marinara Pasta hot, garnished with grated Parmesan cheese if desired.
