Brown the chuck roast on all sides in a hot skillet before adding to the slow cooker to develop a rich, caramelized crust that deepens the overall flavor of your broth.

Cut carrots and potatoes into uniform, larger chunks so they don't disintegrate during the long cooking process and maintain their structure for an appealing presentation.

Place half the onions and garlic on the slow cooker bottom before the roast, then add the remaining half on top to create depth of flavor throughout the broth.

Stir in the worcestershire sauce in the last 30 minutes of cooking rather than at the beginning to preserve its complex umami notes and prevent them from cooking off.

Select a chuck roast with visible white fat throughout the meat, as this fat renders during slow cooking to create an incredibly tender and flavorful result.
