Begin by boiling a pot of salted water and cook the penne pasta according to package instructions until al dente. Drain and set aside.

In a large bowl, combine the steak tips with olive oil, Cajun seasoning, garlic powder, smoked paprika, salt, and black pepper. Mix well to coat the steak.

Heat butter in a large skillet over medium-high heat. Add the steak tips and sear for about 3-4 minutes until they’re browned and cooked to your desired doneness. Remove the steak from the skillet and set aside.

In the same skillet, add minced garlic and sauté for about 1 minute until fragrant. Pour in heavy cream and whole milk, stir to combine.

Add in the cream cheese gradually, mixing until melted and creamy.

Stir in the freshly grated Parmesan and shredded mozzarella cheeses. Mix well until the sauce is smooth. Season with additional Cajun seasoning if desired.

Add the cooked penne pasta and seared steak back into the skillet. Toss until the pasta and steak are well coated with the creamy sauce.

Transfer to serving plates, sprinkle with chopped parsley, and enjoy!
