In a medium mixing bowl, whisk together the Zesty Italian mix, Ranch seasoning, and beef gravy powder. Pour in the beef bone broth and Worcestershire sauce, stirring until you have a smooth, concentrated liquid base.

Pat your roast dry with paper towels. In a hot skillet with a drizzle of oil, sear the meat for 3–4 minutes per side. This locks in the juices and creates a beautiful crust that enhances the final gravy.

Nestle the beef into the basin of your slow cooker. If you are adding vegetables like carrots or potatoes, tuck them around the sides of the meat now.

Pour your prepared seasoned broth directly over the roast, ensuring the top is well-coated.

Secure the lid and set your device to Low. Let it slow-simmer for 8 hours. Resisting the urge to peek is key; keeping the steam trapped ensures the fibers of the chuck roast break down until they are fork-tender.

Once finished, the meat should fall apart with minimal effort. Shred it directly in the pot so it can soak up the rich, seasoned juices before serving.
