FAQs
Can I use a different cut of beef?
Yes, other cuts like brisket or round roast can work, but beef chuck roast is ideal for slow cooking since it becomes tender and flavorful.
Is it necessary to use a slow cooker?
A slow cooker is recommended for the best tender results, but you can also cook the beef in a covered pot in the oven at low heat (around 300°F) for 3–4 hours until tender.

Ingredients
Beef and Gravy
- 2 lbs beef chuck roast, trimmed
- 1 large onion, sliced
- 2 cups beef broth
- 1 packet brown gravy mix (about 1 oz)
- 1 tablespoon Worcestershire sauce
- 1 teaspoon garlic powder
- Salt and black pepper to taste
- 2 tablespoons cornstarch (optional, for thickening)
To Serve
- 3 cups mashed potatoes, prepared
Instructions
- Season the beef: Generously season the beef chuck roast with salt, black pepper, and garlic powder, ensuring all sides are evenly coated for maximum flavor.
- Prepare slow cooker: Place the sliced onions evenly in the bottom of the slow cooker, then carefully lay the seasoned beef roast on top of the onions.
- Make gravy mixture: In a bowl, whisk together the beef broth, brown gravy mix, and Worcestershire sauce until smooth. Pour this mixture evenly over the beef in the slow cooker.
- Slow cook: Cover the slow cooker with its lid and cook on low heat for 8 hours, or until the beef becomes tender enough to shred easily with a fork.

- Shred and combine: Shred the cooked beef using two forks, then return the shredded meat to the thickened gravy and stir to combine.
- Serve: On each plate, place a generous scoop of prepared mashed potatoes, top with the shredded beef, and ladle over plenty of rich, flavorful gravy. Enjoy warm.
Notes

- If you prefer a smoother gravy, strain the cooking liquid before thickening with cornstarch.
- This dish can be prepared ahead of time and refrigerated; reheat gently before serving.
- Mashed potatoes can be homemade or store-bought to save time.
