Tasty Chicago-style Italian Beef made super easy with the help of the Instant Pot. Full of spice and flavor. Sure to be a total crowd pleaser!
Heat the Instant Pot on saute mode. Liberally season the roast with kosher salt, pepper, and Italian seasoning. When 'hot', drizzle olive oil in pot and brown the roast both sides.
Place the onion, bell pepper, and garlic cloves on top of the roast. Dump in the entire jar of pepperoncini peppers. Add the Worcestershire sauce.
Place the lid on the Instant Pot and turn valve to sealing. Cook on Manual for 45-55 min, NPR.
Release the steam valve. Remove the roast and shred. Return the meat to the juices in the pot.
Serve on buttered and toasted rolls. Optional: Place a slice of provolone cheese on top and melt under the broiler.
*If your beef chuck roast is really thick, you may want to cut it into smaller chunks to ensure proper cooking in the instant pot.
