Bring a large pot of salted water to a boil. Add the 8 ounces of fettuccine and cook according to package instructions until al dente, usually about 10-12 minutes. Drain the pasta and set aside, reserving a small cup of pasta water.
While the pasta cooks, heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Add the thin strips of beef steak, seasoning with salt and pepper. Sear the steak for about 2-3 minutes per side until browned but still tender. Remove the steak from the pan and set aside.
Lower the heat to medium and add the minced garlic to the same skillet. Sauté for about 30 seconds to 1 minute until fragrant, being careful not to burn it.
Pour in 1 cup of beef broth and 1 cup of heavy cream to the skillet. Stir in 1 teaspoon of Italian seasoning, then bring the mixture to a gentle simmer. Let it cook for 3-5 minutes, stirring occasionally, until the sauce starts to thicken.
Stir in the grated Parmesan cheese until melted and smooth. Return the cooked steak strips to the skillet, tossing to coat them thoroughly in the creamy sauce. If the sauce is too thick, add a splash of reserved pasta water to loosen it.
Add the drained fettuccine to the skillet and gently toss until every strand is coated with the luscious sauce. Taste and adjust seasoning with salt and pepper if needed.
Transfer the creamy steak pasta to serving plates or a large bowl. Sprinkle generously with freshly chopped parsley for a fresh herbal note and a pop of color. Serve hot and savor every bite.
