Pop the sides of the slow cooker and remove the lid. Place the pot roast in the center of the slow cooker and add salt, pepper, and a packet of au jus seasoning.
To the pot roast, add in the jar of pepperoncinis and the juice from the peppers.
Pour in the beef stock, water, and Worcestershire sauce. Close the lid and set on low for 6 hours (or on high for 4 hours).
When the timer is up, remove the lid and take out the pot roast.
With two forks, shred the pot roast and add to the bottoms of sweet rolls.
Top the sweet rolls with slices of cheese (provolone or swiss work great) and close with the tops of the rolls. Serve with a small bowl of au jus for dipping.
To assemble the sliders:
Slice open small potato dinner rolls. Using tongs, grab some of the pepperoncini pot roast from the slow cooker and spread evenly across the rolls.
Layer a few slices of cheese on top and close with the tops of the rolls.
Ladle a cup of au jus and serve alongside the pot roast sliders.
Notes
Be generous when seasoning the pot roast with salt and pepper. We want to ensure there is enough seasoning while the meat cooks.
