In a large pot, bring salted water to a boil. Add your preferred pasta (penne, rigatoni, or shells) and cook according to package instructions until al dente. Drain and set aside.

In a large skillet, heat a drizzle of olive oil over medium-high heat. Add chopped onion, sautéing for 2-3 minutes until it's translucent and fragrant.

Toss in minced garlic, bouillon, and Italian seasoning. Stir for about 1 minute until the mixture becomes aromatic.

Incorporate the ground beef, breaking it apart with a spatula. Cook until browned, about 5 minutes. Drain excess fat if necessary.

Stir in marinara sauce and let it come to a simmer. Cook for approximately 8 minutes.

Adjust seasonings with salt and pepper to your liking. Fold in the cooked pasta, ensuring every piece is coated in the sauce.

Stir in chopped parsley and grated parmesan for 2-3 minutes until the cheese melts beautifully.
