This One Pot Hamburger Stoganoff is a great weeknight meal! It's quick, easy, filled with simple ingredients, and has NO condensed soup.
In a large skillet over medium heat cook the mushrooms and onion with the butter and olive oil until softened and mushrooms are lightly browned. Add the ground beef and garlic and cook until beef is no longer pink (or until it is mostly cooked, it will continue to cook as it simmers).
Add the flour and stir to coat. Add the broth, uncooked noodles, Worcestershire, beef bullion, and parsley. Cover and simmer for 10 minutes or until pasta is tender. Stir occasionally to prevent sticking. Remove from heat and stir in sour cream. Taste for salt and pepper and season accordingly.
