What is Italian Beef?

Italian Beef is a classic Chicago dish dating back to the 1930’s. It has thinly sliced roast beef cooked in flavorful Italian seasonings until super tender. It’s served with tomatoes and zesty pickled vegetables – sometimes Chicago-style giardiniera ( a mix of different vegetables including carrots, cauliflower, and peppers in hot or mild varieties) or, as we prefer, with zesty pickled peppers called pepperoncini.

The slow cooker is an ideal way to cook the Italian Beef – and it comes out super tender from the long and slow cooking process. We like to eat it on a sub roll with provolone cheese, plus onions, chopped pickled peppers, and the tomatoes!

• It’s a delicious way to feed a hungry crowd at game day parties, but it’s makes a great weeknight meal for your family.
• Prep is super easy, then the slow cooker does the rest of the work so you can go about your day while the beef cooks.
• There’s nothing better than coming how to a house filled with amazing aromas from the slow cooker! You’ll love the fork-tender beef and zesty flavors as well.

• Beef – We selected a bone-in chuck roast, but a boneless chuck roast is also perfectly fine for this recipe. Chuck roast is a very flavorful cut of beef and it gets super tender when slow cooked.
• Onion – We cooked the beef with about a pound of diced red onion (yellow or white would also be fine). We also chopped up some additional red onion to sprinkle over the sub as a garnish.
• Red Wine – Used to deglaze the pan, you can swap in beef broth if you prefer a non-alcoholic option.
• Tomatoes – Some are cooked with the beef while others are chopped and added as a topping when serving the subs.
• Seasonings – Including ground black pepper, Italian seasoning, sugar, celery salt, garlic powder, onion powder, and bay leaves.
• Provolone Cheese
• Sub Rolls – For serving
• Pepperoncini – Also added to the top of the sub when served.

1. Sear the beef and cook the onions until softened.
2. Deglaze the pan with wine or beef stock.
3. Place tomato halves into the bottom of a slow cooker, then place the beef on top of the tomatoes.
4. Pour in any liquid leftover from searing the beef and onions. Also add the seasonings to the slow cooker.
5. Slow-cook on high for 8 to 10 hours, until the beef is super tender.
6. Remove beef to a cutting board and slice for serving, adding in some of the cooked tomatoes and onions to the serving bowl.
7. Line each sub roll with some sliced provolone cheese, fill the roll with hot cooked beef, then top with uncooked chopped tomatoes, onion, and pepperoncini.

• Can I make this Slow Cooker Italian Beef ahead of time? Yes. You can make it a day ahead, then reheat in a pan or microwave before serving.
• How do I store leftovers? Store covered in the refrigerator for up to three days.
• Can I freeze this dish? Yes. We would suggest only freezing the cooked beef and vegetables. Serve with freshly chopped onions, tomatoes, and pepperoncini.
