Crock Pot Beef Dip Sandwiches

Slow Cooker Instructions

1. Place the beef broth and dry onion soup mix into a large crock pot, stir until combined. Season the roast beef with the pepper and the garlic. Place the oil in a large skillet over medium-high heat, then sear the roast on all sides, then place the beef roast into the liquid in the slow cooker.
2. Cover and cook on low for 6-8 hours or high for 3-4 hours until the meat is fork-tender. Remove the roast from the crock pot and slice into thin slices or shred. If you are shredding the beef it is best to leave some liquid with it to ensure it stays moist and delicious!
3. Preheat your oven to 350 °. Spread the butter on the sub/hoagie buns, stuff the meat and cheese slices into the rolls and place on a baking sheet.. Toast the sandwiches for 5 minutes or until the cheese starts to melt.
4. If desired, strain the liquid in the slow cooker though a sieve into a bowl, then ladle the liquid (au jus) into bowls large enough for dipping for when you are serving.
