1. Bring a large pot of salted water to a boil. Cook the pasta until al dente according to package instructions. Drain, reserving 1/4 cup of pasta water, and set aside.

2. In a large skillet over medium heat, brown the ground beef until no longer pink. Drain excess fat. Add Cajun seasoning and stir to coat the meat evenly.

3. Push the beef to one side of the skillet. Add butter and minced garlic. Sauté until fragrant, about 1 minute. Mix everything together.

4. Lower the heat. Pour in Alfredo sauce and stir. Add Velveeta cubes and let them melt into the sauce, stirring occasionally. Add a splash of reserved pasta water if the sauce is too thick.

5. Add the cooked pasta into the skillet and toss until fully coated. Season with salt and black pepper to taste.

6. Let the pasta simmer for 2 more minutes so the flavors marry together.

7. Serve hot, topped with chopped parsley or extra cheese if desired.
