Bring a large pot of salted water to a boil. Add the pasta and cook according to the package instructions until al dente. Drain and set aside.

While the pasta cooks, heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the steak and season with salt and pepper.

Cook for 3-4 minutes until browned on all sides. Remove from the skillet and set aside.

In a clean skillet, melt the butter over medium heat. Add the heavy cream, Parmesan cheese, and garlic powder. Stir continuously until the sauce thickens, about 5 minutes.

Season the sauce with salt and pepper to taste.

Add the cooked pasta to the skillet with the sauce. Toss to coat the pasta evenly.

Add the cubed steak on top of the pasta.

Garnish with chopped parsley and additional grated parmesan, if desired.
