In a large pot, bring salted water to a boil. Add the rotini and cook according to package instructions until al dente. Drain and set aside.

In a large skillet, heat olive oil over medium heat. Add minced garlic, onions, and bell pepper. Sauté until the onions are translucent.

Pay attention to the garlic; it can burn quickly, altering the dish's flavor dramatically.

Increase the heat to medium-high and add the ground beef to the skillet. Stir until browned. Drain excess fat if necessary.

Ensure you break the meat into small pieces while cooking to achieve even browning.

Stir in Cajun seasoning, tomato sauce, and chicken broth. Bring to a simmer, allowing all flavors to meld together beautifully.

Add the cooked rotini to the sauce. Toss until the pasta is well-coated and everything is heated through.

Sprinkle cheese over the top and cover, allowing it to melt blissfully.

Serve hot, topped with freshly chopped parsley.
