This Slow Cooker Beef Manhattan is classic comfort food made easy. Tender chuck roast cooks low and slow in savory gravy, then gets served over fluffy mashed potatoes for a hearty, hands-off dinner perfect for busy days.
Ingredients
Beef & Gravy
- 2 lb beef chuck roast trimmed
- 1 large onion sliced
- 2 cups beef broth
- 1 packet brown gravy mix about 1 oz
- 1 tbsp Worcestershire sauce
- 1 tsp garlic powder
- 1 tsp salt or to taste
- 0.5 tsp black pepper or to taste
- 2 tbsp cornstarch optional, for thickening
For Serving
- 3 cups mashed potatoes prepared
Instructions
- Season the beef chuck roast on all sides with salt, black pepper, and garlic powder.
- Place sliced onion in the bottom of the slow cooker and set the seasoned beef on top.
- In a bowl, whisk together beef broth, brown gravy mix, and Worcestershire sauce until smooth. Pour over the beef.
- Cover and cook on low for 8 hours, or until the beef is fork-tender.
- If thicker gravy is desired, remove the beef and whisk a cornstarch slurry into the liquid. Cook on high for 15–20 minutes until thickened.
- Shred the beef with two forks and return it to the gravy.
- Serve the beef and gravy generously over warm mashed potatoes.
Notes
For best results, cook on low heat for maximum tenderness. Mushrooms can be added during cooking for extra flavor, and leftover gravy thickens when refrigerated—add broth when reheating if needed.
