Begin by boiling water in a large pot. Once boiling, add a generous pinch of salt and the rigatoni. Cook according to the package instructions until al dente. Drain and set aside.

While the pasta cooks, take the steak tips and pat them dry with a paper towel. Season generously with Cajun seasoning, salt, and pepper.

In a large skillet, heat the olive oil over medium-high heat. Once hot, add the steak tips and sear for about 4-5 minutes until they are nicely browned and cooked to your desired doneness. Remove the steak from the skillet and set aside.

In the same skillet, lower the heat to medium and add the heavy cream. Allow it to simmer for a minute before adding in the grated Parmesan cheese. Stir continuously until the cheese has fully melted and combined with the cream, creating a luxurious sauce.

Add the cooked rigatoni and steak tips back into the skillet. Toss until every piece is coated with the creamy sauce.

Distribute the dish onto plates, garnishing with fresh parsley for that vibrant touch.
