Start by cutting the beef chuck roast into 2-inch chunks. Heat a large skillet over medium-high heat and add a tablespoon of butter. Sear the beef chunks on all sides for about 3-4 minutes until they're nicely browned.

In your slow cooker, combine the seared beef, chopped Yukon Gold potatoes, minced garlic, and beef broth. Pour in the remaining butter and stir gently to ensure everything is well-mixed.

Cover the slow cooker with its lid and set it to low for 7 hours or high for 4 hours.

Once cooked to perfection, carefully ladle the Garlic Butter Beef with Potatoes into bowls. Garnish with freshly chopped parsley.
