Cook fettuccine pasta according to package directions. Drain and set aside.
Season steaks with salt and pepper.
Heat olive oil in a large skillet over medium-high heat. Sear steaks for 3-4 minutes per side for medium-rare, or to desired doneness. Remove steaks from skillet and let rest for 5 minutes before slicing.
In the same skillet, melt butter over medium heat. Add garlic and cook for 1 minute, or until fragrant. Pour in heavy cream and bring to a simmer. Stir in Gorgonzola cheese and Parmesan cheese until melted and smooth.
Add cooked fettuccine pasta to the sauce and toss to coat.
Slice steaks and serve over fettuccine Alfredo.
Notes
Garnish with fresh parsley, if desired. For a richer flavor, add a splash of white wine to the sauce.
