Step 1

Heat pan over medium high heat. Melt butter then add mushrooms. Cook until browned, about 3-5 minutes.

Step 2

Increase heat to high, add beef and cook until browned, about 5 minutes. Stir in flour, Worcestershire, mustard, garlic powder, onion powder, dried herbs, salt, & pepper. Mix until combined.

Step 3

Stir in the beef broth and bring to a low boil. Scrape the bottom of the pan to deglaze it with the broth. Add the pasta, reduce heat to a simmer, and cover the pan. Stir pasta every 2 minutes or so to turn to top pasta into the broth to ensure even cooking. Cook for 6-10 minutes or until pasta is cooked to your desired texture.

Step 4

Stir in sour cream and cook for another minute or so, until the sour cream is heated through. Taste for seasonings and add more salt/pepper if needed. Top with fresh parsley and serve warm.
