Table of Contents

Ingredients

3 lb chuck roast, trimmed of visible fat and cut into large pieces
1 envelope Italian salad dressing mix (see notes)
8 oz sliced pepperoncini peppers, plus a splash of juice (extra for serving)
8 oz Chicago-style Giardiniera, drained (extra for serving)
14.5 oz can beef broth
Provolone cheese slices (optional)
Sandwich buns or rolls

Directions

1. Prepare the beef
Place the chuck roast pieces in the bottom of a 6-quart slow cooker. Sprinkle the Italian salad dressing mix evenly over the meat.

2. Add the flavorings
Add the sliced pepperoncini peppers, a splash of their juice, and the drained Giardiniera. Pour in the beef broth, lifting the roast pieces slightly so the broth seeps underneath.

3. Slow cook the beef
Cover with the lid and cook on Low for 9 hours, or until the beef is tender and shreds easily with a fork.

4. Shred and simmer
Shred the beef directly in the slow cooker using two forks. Stir well to combine with the juices and vegetables. Cover again and cook on Low for 1 additional hour to let the flavors meld.

5. Assemble the sandwiches
Split the buns in half. Pile the shredded Italian beef onto each bun and top with a slice of provolone cheese (toast or broil gluten-free buns first, if using). Add extra pepperoncini peppers or Giardiniera for more flavor. Serve warm.

Tips

For a richer flavor, brown the beef on all sides in a skillet before adding it to the crock pot.
Use high-quality Italian dressing mix for the best seasoning balance.
Don’t skip the extra hour after shredding—the beef absorbs even more flavor as it rests in the juices.
Toasting the buns prevents them from getting soggy.

Variations and Substitutions

Cheese Options: Swap provolone for mozzarella or Swiss cheese for a different melt.
Heat Level: Add crushed red pepper flakes or spicy Giardiniera for extra kick.
Meat: Try bottom round roast or brisket if chuck roast isn’t available.
Low-Sodium: Use reduced-sodium broth and rinse the Giardiniera lightly before adding.

FAQs

Can I make this ahead of time?
Yes. The beef tastes even better the next day. Store in the fridge up to 4 days and reheat in its juices.

Can I freeze Italian beef?
Absolutely. Freeze in portions with some of the cooking liquid for up to 3 months. Thaw overnight in the refrigerator and reheat gently.

What’s Giardiniera?
It’s an Italian pickled vegetable mix (often with carrots, cauliflower, and peppers) that adds a tangy, spicy flavor to the beef.

Serving Suggestions

Serve these sandwiches with a side of potato chips, French fries, coleslaw, or a green salad. For a true Chicago-style experience, dip the sandwich into the warm cooking juices before serving.
