01 - Bring a large pot of salted water to a boil. Cook bowtie pasta according to package directions until al dente. Drain, reserving ½ cup pasta water, and set aside.
02 - In a medium bowl, combine beef strips with olive oil, smoked paprika, Cajun seasoning, garlic powder, onion powder, salt, and black pepper. Toss until evenly coated.
03 - Heat a large skillet over medium-high heat. Add seasoned beef and cook 3–4 minutes, stirring occasionally, until browned and cooked through. Remove from skillet and set aside, loosely covered.
04 - Reduce skillet heat to medium. Add butter and minced garlic; sauté 1 minute until fragrant.
05 - Pour in heavy cream and add cubed cream cheese. Stir continuously until cream cheese melts completely and sauce is smooth.
06 - Stir in Parmesan cheese, Cajun seasoning, and red pepper flakes. Simmer 2–3 minutes, stirring frequently, until sauce thickens. Season with salt and pepper to taste.
07 - Add drained pasta to the skillet, tossing to coat thoroughly. If sauce is too thick, add reserved pasta water a tablespoon at a time until desired consistency is achieved.
08 - Arrange cooked spiced beef over the pasta. Toss gently to distribute or leave beef on top as a garnish.
09 - Sprinkle with chopped fresh parsley and additional Parmesan cheese. Serve immediately while hot.
