Boil the linguine in salted water until al dente, reserving 1 cup of pasta water before draining.
Sear the seasoned beef strips in a hot skillet with olive oil until browned, then remove to a plate.
Sauté the minced garlic in the butter in the same skillet over medium-low heat for 1 minute.
Simmer the beef broth, heavy cream, and Italian seasoning in the skillet until slightly thickened.
Toss the drained pasta, cooked beef, and grated Parmesan into the sauce off the heat, using pasta water to thin it if needed.
