Heat oil in a medium pot and brown beef cubes. Remove beef from pot.

Add garlic and onion to pot and cook until softened, about three minutes.

Pour in beer, broth (or water), Worcestershire sauce, tomato paste, sugar, and seasonings. Mix to combine.

Return beef to pot, cover and simmer on low until meat is very tender, about one and a half to two hours.

Add carrots and parsnips and continue to simmer until vegetables are tender and liquid is reduced, about 30 minutes. Top with minced parsley before serving.
