Now, it’s time to make the sauce! Add the beef broth to the skillet, stirring to loosen up any browned bits stuck to the pan. Bring the broth to a simmer, and then pour in the heavy cream. This is where the magic happens—turning everything creamy and dreamy!
Let the sauce cook for a few minutes until it thickens slightly. You can always add some of that reserved pasta water if the sauce seems too thick. Just a little bit at a time, and keep stirring until you reach the perfect consistency.
Once the sauce is ready, stir in the shredded provolone cheese. Let the cheese melt into the sauce, creating that rich, velvety texture we’re all after. At this point, taste the sauce and season it with salt and pepper to your liking.
