Ingredients

Main Ingredients

  • 3 pounds chuck roast
  • 2 cups low-sodium beef broth
  • 1 tablespoon oil of your choice for searing

Homemade Dry Onion & Au Jus Gravy Mix

  • 2 tablespoons dried onion flakes
  • 2 tablespoons cornstarch
  • 2 1/2 teaspoons beef bouillon powder
  • 2 teaspoons onion powder
  • 1 teaspoon garlic powder
  • 1 1/2 teaspoons dried parsley
  • 1/2 teaspoon black pepper

Instructions

  1. Optional Searing: Heat oil in a large skillet over medium-high heat. Once hot, add the chuck roast and cook for a few minutes on each side until browned. This step adds flavor but can be skipped for convenience.
  2. Prepare Gravy: In the slow cooker insert, whisk together beef broth, dried onion flakes, cornstarch, beef bouillon powder, onion powder, garlic powder, dried parsley, and black pepper until smooth with no lumps.
  3. Add Roast to Slow Cooker: Place the browned (or raw) chuck roast into the slow cooker with the gravy mixture, ensuring the roast is mostly submerged.
  4. Cook Beef: Cover and cook on HIGH for 4 to 5 hours or on LOW for 8 to 10 hours until the beef is tender and can be easily shredded.
  5. Shred Beef: Remove the roast from the slow cooker and shred it using two forks. Discard any large pieces of fat.
  6. Combine Beef with Gravy: Return the shredded beef to the slow cooker and stir well to coat the meat with the gravy.
  7. Serve: Spoon the shredded beef and gravy generously over slices of bread. Serve alongside creamy mashed potatoes for the classic beef Manhattan experience.

Notes

  • Optional searing enhances flavor by browning the meat but the roast will still be delicious if seared or added raw.
  • You can prepare the mashed potatoes shortly before the beef finishes cooking to serve everything hot and fresh.
  • Using low-sodium beef broth and homemade spice mix reduces sodium content compared to packaged mixes.
  • If preferred, this recipe can also be adapted to an Instant Pot using the provided pressure cooking instructions for a faster preparation.
