Step 1

Place the chuck roast in the bottom of the slow cooker. Season all sides with the onion soup mix, garlic, and thyme.

Step 2

Pour the Worcestershire sauce and onion soup over the top of the chuck roast. Cut one tablespoon of butter into two pats, and place them on top of the roast. Then place the lid on the slow cooker.

Step 3

Cook for 6-8 hours on high, or 8-10 hours on low.

Step 4

Once done, carefully remove the roast and shred the meat, discarding any extra fat or connective tissues.

Step 5

Drain the fat from the juices and place in a bowl, or bowls for the au jus dipping sauce.

Step 6

Melt the remaining 3 tablespoons of butter. Cut each roll in half and brush with butter. Place the rolls on a baking sheet cut side up and broil for 2-4 minutes or until the edges are toasted.

Step 7

Make sandwiches by adding the shredded beef to the rolls, topping with cheese, then serving with a bowl of the au jus dipping sauce.
