Step 1: Bring a large pot of salted water to a boil. Add the bowtie pasta and cook until al dente, about 10 to 11 minutes. Before draining, reserve ½ cup of the pasta water. Drain and set the pasta aside.

Step 2: Pat the steak tips dry with paper towels. Season evenly with Cajun seasoning, garlic powder, smoked paprika, salt, and black pepper.

Step 3: Heat olive oil and 1 tablespoon of butter in a large skillet over medium-high heat. Add the steak tips in a single layer. Sear for 1 to 2 minutes per side until browned and cooked through. Remove the steak from the skillet and set aside.

Step 4: Lower the heat to medium. In the same skillet, add the remaining 2 tablespoons of butter. Stir in the minced garlic and cook for about 30 seconds until fragrant.

Step 5: Pour in the heavy cream and milk. Add the softened cream cheese and stir until fully melted and smooth.

Step 6: Add the Parmesan, mozzarella, and remaining ½ teaspoon of Cajun seasoning. Stir continuously until the cheese melts and the sauce becomes creamy. Season with salt and pepper to taste.

Step 7: Add the cooked bowtie pasta to the skillet. Toss gently to coat the pasta in the sauce. If the sauce is too thick, add a splash of reserved pasta water to loosen it.

Step 8: Plate the cheesy pasta and top with the seared Cajun steak tips. Garnish with chopped parsley before serving.
