How to Make Crockpot Roast Beef Sandwiches
This Crockpot Roast Beef Sandwiches recipe is exceptionally easy, taking just minutes to prep before your slow cooker does all the work. Imagine sinking your teeth into impossibly tender, shredded beef infused with savory flavors, creating a sandwich that rivals any deli classic. With a total preparation time of about 10 minutes and a slow cooking time of 6-8 hours, this dish is the epitome of effortless, satisfying home cooking.
Step-by-Step Instructions
- Prepare the Roast: Pat the beef chuck roast dry with paper towels. This helps create a better sear if you choose to sear it first (though it’s optional for this recipe). If searing, season the roast generously with salt and pepper on all sides. Heat a tablespoon of oil in a skillet over medium-high heat and sear the roast for 2-3 minutes per side until browned. This step adds an extra layer of flavor but is not essential if you’re short on time.
- Assemble in the Crockpot: Place the beef chuck roast in your slow cooker.
- Add Seasonings: In a small bowl, whisk together the dry onion soup mix, dry brown gravy mix, garlic powder, and black pepper. Sprinkle this seasoning mixture evenly over the top of the beef roast.
- Add Liquids: Pour the beef broth (or water) and Worcestershire sauce around the roast in the slow cooker.
- Slow Cook: Cover the slow cooker and cook on LOW for 6-8 hours, or on HIGH for 4-5 hours, until the beef is fork-tender and easily shreds apart. The exact cooking time will depend on your slow cooker and the size of your roast.
- Shred the Beef: Once the roast is cooked and tender, carefully remove it from the slow cooker and place it on a cutting board or in a large bowl. Using two forks, shred the beef into bite-sized pieces.
- Combine with Juices: Return the shredded beef to the slow cooker with the remaining cooking liquid. Stir the shredded beef into the liquid, ensuring it is well coated. The liquid will have thickened into a rich, flavorful gravy.
- Toast the Buns (Optional but Recommended): While the beef is resting or as it finishes cooking, lightly toast your hoagie rolls or slider buns. You can do this in a toaster, under the broiler for a minute, or in a dry skillet.
- Assemble the Sandwiches: Spoon generous amounts of the shredded roast beef and its savory gravy onto the bottom halves of your toasted buns.
- Add Toppings: Add your desired optional toppings. Melted Provolone cheese is a classic choice and pairs beautifully with the rich beef. Sautéed onions and peppers add a sweet and savory crunch, while pickles provide a refreshing tang. A smear of mayonnaise can add extra creaminess.
- Serve: Place the top half of the bun on your sandwich and serve immediately. Enjoy your delicious and easy Crockpot Roast Beef Sandwiches!

Storing and Reheating Tips

To reheat, you can warm the shredded beef and gravy gently in a saucepan over low heat or in the microwave until heated through. If reheating in the microwave, stir occasionally to ensure even heating. You can then toast fresh buns and assemble your sandwiches. Alternatively, you can place the leftover shredded beef and gravy in freezer-safe containers and freeze for up to 2-3 months for future easy meals. Thaw overnight in the refrigerator before reheating.
