Pat the roast dry with paper towels and season it with salt and pepper.
Reserve 2 tablespoons of beef broth from the 3 cups of beef broth. Set them aside.
In a large measuring cup or medium bowl, combine the larger amount of beef broth and the Worcestershire sauce. Set the mixture aside.
Heat the olive oil in a large skillet or Dutch oven over medium-high heat. Add the roast and sear on all sides until browned evenly. Carefully transfer the roast to a slow cooker.
In the same skillet or Dutch oven you used to brown your roast, reduce the heat to medium. Add the onions and cook them until they are tender. Next, add the garlic and cook it until it is fragrant, about 30 seconds.
Add the 2 reserved tablespoons of beef broth to the skillet or Dutch oven. Using a wooden spoon, scrape the bottom of the pan and carefully transfer the entire mixture to the slow cooker.
Add the beef broth and Worcestershire mixture and the bay leaf and onion powder to the slow cooker.
Cook on high for 4 hours or on low for 6 hours until the roast is tender and has reached an internal temperature of at least 145 degrees on an instant-read thermometer.
Transfer the roast from the slow cooker to a cutting board. Thinly slice the meat on the diagonal.
Prepare your au jus. Place a fine mesh strainer over a large bowl, and pour the juices from the slow cooker into the strainer.
Transfer the onions in the strainer to a small bowl and discard the bay leaf.
Place the sliced meat back into the slow cooker along with the onions. Moisten the meat by pouring in 1/4 cup of the au jus from the large bowl.
Preheat the oven to 350 degrees.
Split the hoagie rolls lengthwise and butter them.
Gently toast the rolls on a baking sheet in the oven until they are warmed through and lightly crispy, about 5 minutes.
Spread the meat and onion mixture on the hoagie rolls. Add 2 slices of Swiss cheese to each sandwich.
Serve with au jus on the side for dipping. Enjoy!
If you prefer your cheese melted, simply pop the sandwiches back into the oven on the baking sheet under the broiler for 1-2 minutes.
