Ingredients
- For the Beef:
- 1 large yellow onion, sliced
- 4 lb chuck roast, trimmed
- 1 tsp black pepper, freshly ground
- 1 oz au jus gravy mix (1 packet)
- 1 oz onion soup mix (1 packet)
- 2 tsp Worcestershire sauce
- 2 cups beef broth
- For the Sandwiches:
- 8 medium hoagie rolls
- 3 tbsp butter, softened
- 8 oz provolone cheese, sliced
- Freshly chopped parsley, for garnish
Instructions
- Place the sliced onions in the bottom of the slow cooker. Season the chuck roast with black pepper on both sides and place it on top of the onions.
- Sprinkle the au jus mix and onion soup mix over the top of the beef.
- In a separate bowl, mix together the Worcestershire sauce and beef broth, then pour it into the slow cooker. If you prefer more gravy for dipping, use more beef broth.
- Cover and cook on LOW for 7 to 8 hours, or until the beef is very tender and falls apart easily.
- Carefully remove the beef from the slow cooker. Use a slotted spoon to remove the onions and place them in a separate bowl for later.
- Using a fine-mesh strainer, pour the drippings from the slow cooker into a bowl or gravy boat to use as the dipping sauce for the sandwiches.
- Assemble the Sandwiches: Cut the sandwich rolls open and spread butter (if desired) on the inside. Toast until lightly browned.
- Top with shredded beef, onions, and provolone cheese.
- Garnish with freshly chopped parsley, if desired.
- Serve the toasted sandwiches with the warm dipping sauce and enjoy!
Notes
- If you prefer a spicier sandwich, add some hot sauce or horseradish to the beef before serving.
- For a richer flavor, you can also sauté the onions in butter before adding them to the slow cooker.
- If you don’t have provolone cheese, mozzarella or Swiss cheese works well as alternatives.
- Feel free to adjust the amount of beef broth depending on how much gravy you want to serve with your sandwiches.
