Ingredients

Scale

Beef and Seasoning

  • 2 pounds beef roast (chuck or round works well)
  • 1 medium onion, sliced
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon dried thyme
  • 1 teaspoon black pepper
  • 1/2 teaspoon salt

Broth and Sauces

  • 2 cups beef broth
  • 2 tablespoons Worcestershire sauce
  • 1 tablespoon soy sauce

Gravy Thickener

  • 2 tablespoons cornstarch
  • 2 tablespoons cold water

To Serve

  • 6 slices of bread (white or Texas toast style)
  • 4 cups mashed potatoes (homemade or prepared)

Instructions

  1. Prepare the slow cooker: Place the sliced onion in the bottom of your slow cooker to form a flavorful base layer.
  2. Add the beef: Lay the beef roast on top of the onions in the slow cooker, ensuring even placement for consistent cooking.
  3. Mix liquids and seasonings: Pour beef broth, Worcestershire sauce, and soy sauce over the beef. Then sprinkle garlic powder, onion powder, dried thyme, black pepper, and salt evenly on top.
  4. Cook low and slow: Cover the slow cooker and cook on LOW for 8 hours or on HIGH for 4 to 5 hours, until the beef is tender and easily shredded.
  5. Shred the beef: Remove the beef roast from the slow cooker and shred it using two forks, breaking it into bite-sized, tender pieces.
  6. Prepare the gravy: Strain the cooked onions from the slow cooker liquid and return the broth to the pot. Stir in a slurry made from 2 tablespoons cornstarch mixed with 2 tablespoons cold water. Heat gently, stirring continuously until the gravy thickens.
  7. Assemble and serve: Place a slice of bread on a plate, top with a generous helping of mashed potatoes, add shredded beef, and ladle the thickened gravy over the entire dish for a classic Beef Manhattan experience.

Notes

  • Use a chuck roast for the best flavor and tenderness.
  • For thicker gravy, add cornstarch slurry gradually and cook until desired consistency.
  • Mashed potatoes can be homemade or store-bought depending on convenience.
  • White bread or Texas toast works best to soak up the gravy without falling apart.
  • This dish can be prepared a day ahead; simply store components separately and reheat before assembling.
