These slow cooker Italian beef sandwiches are one of those dinners that look like you put in way more effort than you actually did. The beef cooks low and slow until it is fall-apart tender, then gets piled high onto toasted rolls with melty provolone and that tangy kick from pepperoncini and giardiniera. It is messy, saucy, and full of flavor in every bite, and somehow always disappears faster than you expect.
If you are already planning these sandwiches for dinner, there are a few more recipes that fit right into the rotation. Red Cabbage Slaw adds that crunchy, fresh bite that cuts through all the rich beef, and Creamy Greek Yogurt Coleslaw is another easy side when you want something simple but still balanced. For something warm and filling alongside it, Sheet Pan Chicken Thighs is one I keep coming back to on busy nights, and if you want to end things on a sweet note, Strawberry Dump Cake is always the easiest crowd pleaser to throw together.

Ingredients
- Chuck roast
- Olive oil
- Onion
- Garlic
- Italian dressing mix
- Salt
- Crushed red pepper flakes
- Black pepper
- Beef broth
- Pepperoncini peppers
- Pepperoncini juice
- Giardiniera
- Hoagie rolls
- Provolone cheese
Directions
Heat olive oil in a large skillet over medium-high heat. Sear the chuck roast on all sides until deeply browned to develop rich flavor. Place the seared roast into the slow cooker.
Add the sliced onion and minced garlic on top of the roast. Sprinkle the Italian seasoning, red pepper flakes, salt, and pepper evenly over the meat. Pour the beef broth and pepperoncini juice around the roast. Top with the pepperoncini peppers.
Cover and cook on low for 8 hours or high for 5 hours, until the beef is fork-tender and easy to shred.
Remove the roast and shred it using two forks. Return the shredded beef to the slow cooker and stir it into the juices. Let it soak for at least 15 to 20 minutes to absorb maximum flavor. To assemble, split the hoagie rolls and toast lightly if desired. Place a slice of provolone cheese on the bottom of each roll. Pile the shredded beef onto each roll, spooning extra juices over the top. Finish each sandwich with a generous spoonful of giardiniera for a bright, tangy crunch. Serve with extra au jus for dipping, if desired.
How do you serve this? What do I serve with this recipe?
- Serve these sandwiches hot, piled high, and do not even try to keep them neat. Spoon extra juices right over the beef so everything soaks in, then add a side of that au jus for dipping because that is where all the flavor is. I usually throw them on a tray with some chips or a quick slaw and call it dinner, but fair warning, people will go back for seconds before you even sit down.
FAQs (Because Life’s Too Busy for Guesswork)
Giardiniera is a mix of pickled vegetables such as carrots, cauliflower, celery, and peppers packed in oil or vinegar, adding tangy crunch and heat.
Yes, you can stir some into the slow cooker during the last 30 minutes of cooking for deeper flavor, though adding it fresh on top keeps the texture crisp.
It has mild heat, but using hot giardiniera will increase the spice level significantly.
Sturdy hoagie or French rolls work best because they hold up well to the juicy beef and toppings.
What are substitutions that I can make?
- Chuck roast – You can use a bottom round roast or rump roast if that is what you have on hand. Just make sure it has some fat so it stays tender.
- Pepperoncini – Banana peppers will give you a similar tangy flavor if needed.
- Giardiniera – You can skip it or swap in extra pepperoncini, but it does add that little crunch and extra flavor on top.
- Provolone cheese – Mozzarella or Swiss both melt well and work great on these sandwiches.
- Hoagie rolls – Any sturdy sandwich roll works. Sub rolls or even toasted hamburger buns will get the job done.
How should I store my leftovers?
- Slow Cooker Italian Beef should be stored in an airtight container in the refrigerator for up to 4 days. Keep the beef with the juices so it stays tender and does not dry out. To reheat, warm it on the stovetop over medium heat or in the microwave until heated through.
- To freeze, let the beef cool completely, then transfer it with the juices into a freezer-safe bag or container. Freeze for up to 3 months. Defrost in the refrigerator overnight and reheat on the stove so it soaks back up all that flavor.
