Cook the beef in a large skillet over medium heat until browned, about 5-7 minutes.
Add the diced onion to the skillet and sauté until translucent, about 4-5 minutes.
Stir in the minced garlic and cook for another minute until fragrant.
Pour in the crushed tomatoes and beef broth, stirring to combine.
Add oregano, basil, salt, and pepper, stirring to incorporate.
Reduce heat to low, and let the sauce simmer for at least 30 minutes, stirring occasionally.
While the sauce simmers, cook the pasta according to package instructions until al dente.
Drain the pasta and add it directly to the ragu, tossing to coat the noodles.
Serve hot, topped with grated Parmesan cheese.
