Boil a large pot of salted water and cook fettuccine according to package directions until al dente.
Season steak strips with salt and half of the cracked pepper.
Heat olive oil in a large skillet over medium-high heat.
Sear steak strips in batches until browned, about 2-3 minutes; remove from pan and set aside.
Reduce heat to medium, add butter and garlic, and sauté for 1 minute until fragrant.
Deglaze the skillet with beef broth, scraping up browned bits.
Stir in heavy cream and the remaining cracked pepper; simmer for 3-5 minutes until slightly thickened.
Whisk in Parmesan cheese until smooth.
Add cooked pasta and steak back into the skillet, tossing to coat thoroughly in the sauce.
Garnish with fresh parsley and serve immediately.
