Prepare the Steak: Generously season both steaks with salt and pepper on all sides. Preheat a cast iron skillet or heavy-bottomed pan over medium-high heat. Add 1 tablespoon of butter and let it melt and sizzle.

② Sear to Perfection: Add the seasoned steaks to the hot skillet and cook until beautifully caramelized and golden brown, about 2-4 minutes per side. Cook to your desired doneness – aim for 145-155°F internal temperature for medium. Remove steaks from skillet, cover with foil, and let rest for 10 minutes while you prepare the pasta and sauce.

③ Cook the Pasta: While the steak rests, bring a large pot of salted water to a rolling boil. Add fettuccine and cook until al dente according to package directions. Drain and set aside, reserving ½ cup of pasta water if needed.

④ Create the Alfredo Magic: Return the same skillet used for the steak to medium heat. Add remaining 2 tablespoons of butter, heavy cream, and parmesan cheese. Stir constantly until the cheese melts completely and the sauce becomes smooth and creamy, about 5 minutes. Season with salt and pepper to taste.

⑤ Combine & Serve: Add the drained fettuccine to the alfredo sauce and toss gently to coat every strand. Slice the rested steak against the grain into thick strips. Serve the creamy pasta topped with the sliced steak and an extra sprinkle of parmesan cheese if desired.
