Start by bringing a large pot of salted water to a rolling boil over high heat. Add the twisted pasta and cook according to package instructions until al dente, about 8-10 minutes.

In a large skillet, heat 2 tablespoons of olive oil over medium-high heat until shimmering. Add the sirloin steak bites in a single layer and sear for 3-4 minutes, flipping once, until golden-brown.

Reduce the heat to medium and add 2 tablespoons of butter to the same skillet. Once melted, pour in 1 cup of heavy cream and sprinkle in Cajun seasoning. Simmer for 2-3 minutes.

Stir in the cooked twisted pasta into the creamy sauce, ensuring each piece is coated. Add in the warm steak bites along with ½ cup of grated Parmesan cheese and gently fold to combine.
