Cook the fettuccine pasta according to package instructions until al dente. Drain and set aside.
In a large skillet, heat the olive oil over medium-high heat. Add the sliced steak and season with salt and pepper. Cook until browned, about 3-4 minutes. Remove the steak from the skillet and set aside.
In the same skillet, add the minced garlic and sauté for about 1 minute until fragrant.
Pour in the beef broth and bring to a simmer. Let it cook for 2-3 minutes to reduce slightly.
Lower the heat and stir in the heavy cream, Italian seasoning, and Parmesan cheese. Mix until the cheese is melted and the sauce is smooth.
Return the cooked steak to the skillet and add the drained fettuccine. Toss everything together until the pasta is well coated in the creamy sauce.
Serve immediately, garnished with fresh parsley.
