Notes

Make Italian Beef Subs for your next game day party. The slow cooker makes prep super easy!

Whether you are hosting a game day party at home, or traveling with your slow cooker to a tailgate party at the stadium, today’s recipe for Slow Cooker Italian Beef Subs is sure to be a fan favorite!

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.

Key Ingredients & Substititions

  • 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.

Special Tools You’ll Need

  • Slow Cooker – Ours is 6-quarts
  • Cutting Board & Knife
  • Large Dutch Oven or Heavy Pot – Used to sear the beef.

How do I make Slow Cooker Italian Beef Subs?

  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.

Serving Tip

The hot cooking liquid from the slow cooker can be served and used to dip the sandwich (similar to a French dipped sandwich) but this step is optional.

    We love Italian beef subs made in the slow cooker. Sometimes we grill the chuck roast to brown it but MOST of the time we simply put it plus a jar of sliced pepperoncini and a jar of giardiniera (including the juices) and cook on low all day. We then shred the beef and dress the sandwiches just as you do using provolone and mozzarella slices. It is a true “dump & go” dinner made this way BUT I think we’ll have to do a taste comparison! HA!

    We just served this last weekend for 15 for my husband’s birthday celebration

    HELLO, JUST DISCOVERED YOUR SITE TODAY AND AM SUPER EXCITED TO REVIEW AND TRY YOUR RECIPES. EVERYTHING LOOKS SO DELICIOUS AND THIS IS THE FIRST SITE, OTHER THAN FOOD NETWORK, THAT I HAVE FOUND, THAT IS SAVORY AND SWEET AND ENTICING.

    QUESTION, I HAVE PRINTED OUT YOUR SLOW COOKER ITALIAN BEEF SUBS RECIPE. THE INSTRUCTIONS MENTION TO COOK IN SLOW COOKER FOR 8-10 HOURS ON HIGH. IS THAT CORRECT? OR SHOULD IT BE LOW FOR 8-10 HOURS.

    Reply

    • Slow Cooker Italian Beef Subs (22)Jack says

      We did in fact cook ours on high for nine hours. Five pounds of chuck roast is a large piece of beef and the higher temperature is needed to cook it through. That said, slow cookers models vary so please feel free to check sooner if you think that your slow cooker may cook a little faster.

      Good luck,
      Jack
