Instructions
In the Multicooker, whisk together the broth, wine, tomato paste, mustard, Worcestershire, and 1/2 teaspoon of the black pepper.
Add the potatoes, carrots, parsnips, onions, and rosemary to the pot, and toss to combine.
Season the beef with the salt and remaining 1/2 teaspoon black pepper.
Nestle the beef into the vegetables in the pot. Cover with the lid, press [Roast], and adjust the temperature to 300°F and the timer to 2 hours 30 minutes.
Cook until the beef is very tender, about 2 hours 15 minutes. Press Cancel.
Remove and discard the rosemary. Transfer the beef to a cutting board, remove the string (if using), and slice thinly.
Arrange the beef and vegetables on a serving platter or plates, spooning any remaining liquid over the top. Sprinkle with parsley (if using).
