With melt-in-your-mouth beef, melted provolone, and a tangy touch of Giardiniera and seasonings, these hearty sandwiches are easy to make right in the slow cooker. Crock Pot Italian Beef Sandwiches are the perfect comfort food that's both easy and satisfying for a busy weeknight or to feed a crowd!
Add sliced onion to the bottom of a 6-quart slow cooker and pour beef broth over the top. Season both sides of the roast with salt and pepper. Place roast on top of the onions.
Sprinkle garlic, Italian salad dressing mix, Italian seasoning, pepperoncini pepper slices, and Italian mix Giardiniera over the top.
Cover and cook on low for 8-9 hours or high for 5-6 hours.
Remove beef and shred with two forks and return to the slow cooker. Mix until combined and continue to cook for thirty minutes.
Preheat your oven to 350℉. Open your hoagie rolls, put two pieces of cheese in them, and then place them on a baking sheet. Bake for about 5 minutes or until cheese is melted.
Garnish with extra Italian mix Giardiniera, and enjoy!
