Bring a large pot of generously salted water to a boil. Add the twisted pasta and cook according to package instructions until al dente (tender but still firm to the bite). Before draining, reserve about 1/2 cup of the pasta cooking water to use later if needed. Drain the pasta and set aside.
02 -
While the pasta is cooking, prepare the steak. Pat the cubed steak dry with paper towels - this is crucial for achieving a good sear. Season the steak generously with salt, pepper, garlic powder, and smoked paprika, tossing to coat all sides evenly.

Heat the olive oil in a large skillet over medium-high heat until shimmering but not smoking. Working in batches if necessary to avoid overcrowding, add the seasoned steak cubes to the hot skillet in a single layer. Let them cook undisturbed for 1-2 minutes to develop a good sear, then use tongs to turn them and brown all sides. This should take about 3-4 minutes total for medium-rare to medium doneness. Remove the seared steak bites from the skillet and set aside on a plate, tented loosely with foil to keep warm. Repeat with any remaining steak.

In the same skillet with all those flavorful browned bits from the steak, reduce the heat to medium and add the 4 tablespoons of butter. Once melted, add the minced garlic and sauté for 1-2 minutes until fragrant and lightly golden, being careful not to burn it. If using the optional red pepper flakes, add them now to infuse the butter with heat.
05 -
Pour the heavy cream into the skillet with the garlic butter. Stir in the Cajun seasoning, garlic powder, and a bit of salt and pepper to taste. Bring the mixture to a gentle simmer and let it bubble for 3-4 minutes, stirring occasionally, until it begins to thicken slightly. Reduce the heat to low and gradually whisk in the grated Parmesan cheese until completely melted and the sauce is smooth and velvety.
06 -
Add the drained pasta directly to the skillet with the Cajun Alfredo sauce. Toss thoroughly to coat every piece of pasta with the creamy sauce. If the sauce seems too thick, add a splash of the reserved pasta water, a little at a time, until you reach your desired consistency. Taste and adjust seasonings if needed.
07 -
Gently fold the seared steak bites back into the skillet, along with any accumulated juices from the plate. Stir gently to combine everything, allowing the steak to warm through in the hot pasta and sauce, about 1-2 minutes. Be careful not to overcook the steak at this stage.
08 -
Transfer the pasta and steak bites to a large serving dish or individual plates. Sprinkle generously with freshly chopped parsley for color and a bright, fresh flavor. If desired, offer additional grated Parmesan cheese at the table. Serve immediately while hot and enjoy!
