Ingredients

Meat and Seasoning

  • 2 1/2 to 3 pounds beef chuck roast
  • Kosher salt, to taste
  • Freshly ground black pepper, to taste
  • 2 tablespoons olive oil

Slow Cooker Liquids & Soup Mix

  • 2 (1-ounce) packages dry onion soup mix
  • 2 cups water
  • 2 (14.5-ounce) cans beef broth

Sandwich Assembly

  • 6-8 slices Swiss or provolone cheese
  • 6-8 crusty rolls (such as ciabatta)

Instructions

  1. Season and Heat Oil: Heat olive oil in a large skillet over medium-high heat. While the oil is heating, generously season all sides of the chuck roast with kosher salt and freshly ground black pepper to enhance the meat’s flavor.
  2. Sear the Roast: Once the oil starts to shimmer, carefully place the seasoned roast in the hot pan. Sear it on all sides by letting it sit undisturbed for about 1-2 minutes per side until it’s nicely browned. This process locks in the juices and adds rich flavor.
  3. Transfer to Slow Cooker: Move the seared roast along with pan juices into your slow cooker. Sprinkle the dry onion soup mix evenly over the roast, then pour in the water and beef broth to create a flavorful cooking liquid.
  4. Slow Cook the Meat: Cover and cook the roast on high for 4-6 hours or on low for 8-10 hours. The goal is to cook until the beef is so tender it shreds easily with a fork.
  5. Shred the Beef: Remove the cooked roast from the slow cooker and shred it using two forks, separating the meat into bite-sized pieces that will be perfect for sandwiches.
  6. Prepare Sandwiches: Slice the crusty rolls and pile generous portions of shredded beef onto each. Top with a slice of Swiss or provolone cheese.
  7. Melt the Cheese: Place the assembled sandwiches on a baking sheet and broil them in the oven just long enough to melt the cheese and toast the top bun lightly.
  8. Serve with Au Jus: Serve the sandwiches hot, accompanied by the cooking juices (au jus) from the slow cooker for dipping, enhancing every bite with savory flavor.

Notes

  • For a crispier sandwich, you can toast the bottom bun before assembling.
  • Use leftover au jus by straining and refrigerating for up to 3 days or freeze for longer storage.
  • Substitute provolone or mozzarella if you prefer a milder cheese flavor.
  • For an even richer au jus, you can simmer the cooking liquid on the stove to reduce and concentrate the flavors.
  • Ensure not to skip the searing step, as it adds essential depth of flavor to the roast.
