Place beef cubes, flour, salt and pepper in a large ziplock bag and shake to coat meat.
Heat oil in a soup pot and add meat (discarding excess flour mixture), stirring frequently to sear. Stir in onion, dried mustard, Worcestershire sauce, consume and carrots. Turn heat to low and simmer for 40 minutes.
When beef is tender, stir in rutabagas, parsley and lemon juice; cook 10 minutes more.
